EXCLUSIONS
• The termination fitting, as shown in figure 4-21, is not a concealed
joint, and therefore, is not affected by these guidelines. The
termination fitting shall be installed per WARD's instructions.
• Manifold stations, which include the multiport manifold and pressure
regulator, shall not be installed in concealed locations regardless of the
qualifications of the tubing fittings.
• Fittings installed inside accessible enclosure boxes, for such items as
quick connect gas outlets or fireplace shut-off valves, are exempted
from these guidelines.
New Installations
Fireplace Logs
The connection to a valve controlling gas flow to a fireplace appliance may be
concealed when installed as shown in figure 4-22. The concealed tubing
fitting can be installed beneath the floor, or hearth, or inside the brickwork of
the fireplace. Wardflex tubing and fittings shall not be installed inside the
firebox for connection of log lighters or gas wands.

Attention
The installation of Gastite® Flexible Gas Piping must be performed by a qualified installer who has successfully completed the
Gastite® training program. The installer must also meet all qualifications required by the state and/or local administrative author-
ity administering the provisions of the code where the gas piping is installed.
This document provides the user with general guidance when designing and installing fuel gas piping using Gastite® Flexible Gas
Piping. This guideline must be used in conjunction with the local building standards and codes. Local requirements will take prece-
dence in the event there is a conflict between this guideline and the local codes. In the absence of local codes, installation must
be in accordance with the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA-54, National Standard of Canada,
Natural Gas Installation Code, CAN/CGA-8149.1, National Standard of Canada, Propane Installation Code, CAN/CGA-B149.2, the
International Fuel Gas Code, the Federal Manufactured Home Construction and Safety Standards, 24 CFR Part 3280, the Manu-
factured Housing Construction and Safety Standards, ICC/ANSI 2.0 or the Standard on Manufactured Housing, NFPA 501.
Special attention must be given to the proper design, installation, testing and use of the gas piping system. Sound engineering
principles and practices must be exercised, as well as diligent adherence to the proper installation procedures. All installed sys-
tems must pass customary installation inspections by the administrative authority prior to being placed in service.
Warning
Improper installation or operation of the system may result in fire, explosion or asphyxiation. Only the components
provided or specified by Gastite® as part of the fuel piping system are to be used in the installation. Use of com-
ponents from other flexible gas piping systems other than those specified as part of the Gastite® system is prohib-
ited and may result in poor system performance and serious bodily injury or property damage. Where additions,
repairs or replacements involve CSST systems from different manufacturers, the systems should be joined using l
standard pipe fittings at the interface.

1.1 Limitations of the Guidelines
This document is intended to aid the professional gas installer in the design, installation and testing of fuel gas piping systems
using corrugated stainless steel tubing (CSST) for residential housing, commercial and industrial buildings. It would be impossi-
ble for this guideline to anticipate and cover every possible variation in building configurations, construction styles, appliance
loads and code restrictions. Therefore, there will be applications that will not be covered by this guideline. For applications that
go beyond the scope of this guideline, the installer should exercise sound engineering principles and practices and/or contact
Gastite® for engineering assistance.
The techniques outlined within this guideline are recommended practice for generic applications. These practices must be
reviewed for compliance with all applicable local fuel gas and building codes. Where a conflict exists between these guidelines
and local requirements, local requirements will take precedence unless a variance is obtained from the administrative author-
ity administering the provisions of the code where the gas piping is installed.
Use of components from other flexible gas piping systems other than those specified as part of the Gastite® system is prohibit-
ed and may result in poor system perform and serious bodily injury or property damage. Additional information pertaining to gas
piping systems is available from your local gas utility or propane supplier.

Section 2.0 Description of System and Components
2.1 System Description
a) The Gastite® Flexible Gas Piping System has been tested in accordance with the American National Standard for Fuel
Gas Piping Systems Using Corrugated Stainless Steel Tubing, ANSI/IAS LC -1. This standard lists performance require-
ments for certification of CSST systems for use with all recognized fuel gases, including Natural Gas and Propane, up
to 5 -PSI operating pressure.
b) Corrugated Stainless Steel Tubing may be used in combination with all approved fuel gas piping materials
using pipe threads at the interface. System components such as manifolds, tees and stub -outs may be fab-
ricated from other approved materials to be used with Gastite® flexible gas piping.
c) The corrugated stainless steel system has a number of essential hardware and design differences from conventional gas
piping using rigid steel pipe and copper tubing. These differences are described as follows:
• System uses corrugated stainless steel tubing (CSST) made of 300 series type material, ASTM A240.
• The tubing is connected using special mechanical brass fittings designed specifically for the Gastite CSST.
• In many applications, the tubing is sized for individual gas appliance loads and is, therefore, usually small in diame-
ter. The tubing may also be installed in a parallel fashion from a central distribution manifold rather than a series lay-
out commonly used for rigid pipe systems.
• The Gastite® Flexible Gas Piping is suitable for use with elevated pressure systems. (Above 1/2 PSI).
• Corrugated Stainless Steel Tubing is pulled through the structure similar in fashion to electrical conduit and therefore
requires different handling and installation techniques than rigid pipe.

3.1 Configuration
3.1.1 Introduction
System Configuration
Prior to piping installation, refer to building plans or prepare a sketch showing the location of the appliances, the various appli-
ance load demands, point of delivery (location of gas meter or second stage LP regulator), and possible piping routes. Appli-
ance load demand data can be obtained from the manufacturer's nameplate located on each appliance, or provided to the sys-
tem designer by the builder/contractor.
a) Determine the local piping restrictions prior to installing the flexible gas piping. Confirm that the local administrative
authority has accepted the use of flexible gas piping. Corrugated Stainless Steel Tubing has been accepted by most
major code bodies, but local or state adoption of these codes often lags behind. Check with the local administrative
authority or an authorized Gastite Distributor for approval in your area.
b) Determine metered (supply) pressure.
3.1.2 Gas pipe sizing and allowable pressure loss
The design flow capacity and pressure loss on any pip-
ing system under maximum probable flow conditions,
from point of delivery to the inlet connection of the
equipment, shall be such that the gas supply volume
and pressure at the equipment is greater than the min-
imum volume and pressure required for proper equip-
ment operation.
Typically when using the "Summation Method" for gas
pipe sizing, the sum of the pressure losses through
each section of pipe should result in a minimum 5"
water column natural gas pressure delivered to the
appliance inlet. (Pressures less than 5" w.c. may be
sufficient for proper appliance operation but should be
reviewed with the manufacturers' input rating and the
local administrative authority)
Natural Gas:
• Standard low-pressure supply throughout the USA and Canada is usually 6-7 inches water column (also designated as
1/4 PSI or 4 ounces).
• Higher pressure supply such as 14 inches w.c. (1/2 PSI) and 2 PSI provide significant CSST size reduction. Check
with the local gas utility for the availability of elevated pressure.
Propane (Liquefied Petroleum Gas):
LP is typically supplied within residential buildings at 11 inches w.c. This pressure is set at the second stage regu-
lator.
Elevated pressure settings from 14 inches w.c. to 2 PSI and 5 PSI also provide CSST size reductions. Check with
the propane gas supplier for available pressure.
Determine the total capacity needed for all appliances. CFH/BTUH equivalents for natural gas or propane flow can be obtained
from the local gas utility or propane supplier. The capacity tables within this guide or any approved CSST tables should be used
to determine pipe sizing needed to meet BTUH input load requirements.
• For natural gas with a specific gravity of 0.60, one cubic foot per hour (1 CFH) is approximately 1,000 BTUH.
• For propane gas with a specific gravity 1.52, one cubic foot per hour (1 CFH) is approximately 2,500 BTUH.

Section 3.0 System Configuration
Refer to section (7.0) for gases with a specific gravity other than .60.
3.1.3 Series Systems
A series layout is the most common arrangement utilized for rigid
pipe systems for low pressure. These usually consist of a main
run (header) with tees branching off to each appliance. In a tradi-
tional series system, the service pressure down stream of the ED
-
meter is typically less than 1/2 PSI.
The minimum pressure supplied to any given appliance is an
important consideration. To operate properly, most Natural Gas
appliances require a minimum of 4 inches water column pres-
sure and most Propane (Liquefied Petroleum) appliances require
a minimum of 10 inches water column pressure. Allowable
pressure drop along any particular run may be dictated by local
code restrictions, typically it is 0.5" (1/2 inch) water column
between the meter and the furthest appliance.
3.1.4 Parallel Systems
In a parallel system, appliances are serviced by individual runs
that stem off from a central distribution manifold. A main run from
the meter supplies the manifold. The manifold station is located
close to the greatest load, typically the boiler or furnace. A par-
allel layout is most likely to be used in medium pressure (14 inch
es water column) and elevated pressure (in excess of 14 inches
water column) systems.
3.1.5 Dual Pressure System
A Dual Pressure system incorporates two operating pressures
downstream from the meter. The first pressure, set by the ser-
vice regulator at the meter, is usually 2 PSI, but can be higher or
lower depending on code restrictions and gas company policy.
This part of the system is sized separately and ends at the
pounds -to -inches regulator inlet. The allowable pressure loss for
this part of the system must be added to the effect of the regula-
tor to determine the available pressure at the regulator outlet.
The chart on page (46) shows pressure losses for maximum loads
through the regulator.
The second pressure, at the outlet of the pounds -to -inches regu-
lator is under 1/2 PSI, usually 8 inches w.c. for natural gas and
11 inches w.c. for propane. Generally, a parallel system requires
a higher total footage of smaller diameter tubing and fewer fittings
compared to a series layout.

3.1.6 Multiple Manifold System l
For those installations in which the energy load demand is large or the appliances are installed throughout the structure with long
distances from the meter, a multiple manifold system may be used. Elevated pressure systems are a safe, efficient method of
providing for larger BTU load demands while maintaining smaller pipe diameters.
3.1.7
Fig. 3-4
Combination Steel / CSST System (Hybrid)
In a hybrid system, corrugated stainless steel tubing is used
in combination with rigid pipe or copper tubing. In low and
medium pressure systems it is often advantageous to use
both CSST and rigid pipe to help minimize pressure drops
typically encountered on systems with high loads and/or
long runs. Gastite®, Flexible Gas Piping is approved for
use in combination with all approved fuel gas -piping
materials by using approved pipe threads at the inter-
face.
3.1.8 Elevated Pressure System
In a complete elevated pressure system, corrugated stainless
steel tubing is used to deliver pressures in excess of 1/2 PSI to
a pounds -to -inches regulator positioned directly in front of each Muar
appliance regulator. This is an alternate method of installation
used to minimize pressure drops typically encountered on sys-
tems with high loads and/or long runs.

3.2 Sizing Procedures and Exercises
3.2.1 Sizing Methods
A modified version of the "longest length method for pipe sizing" (commonly used in conventional rigid pipe systems) is present-
ed in section (3), and used in Example (3.2.4,3.2.5). This method should be used for low-pressure system installations (7 inch-
es water column) and medium pressure installations (14 inch water column or 1/2PSI).
For sizing dual -pressure systems, the piping from the meter to the pounds -to -inches regulator is sized separately from the piping
downstream of the regulator outlet. This procedure is introduced in section (3) and is used in Example (3.2.6).
An alternative sizing method, which considers a summation of the pressure losses through each section of piping, is located in
Section (3.2.8). This procedure is utilized for the designer whose requirements are not satisfied by the previously described
methods. The summation method can be used for system pressures other than indicated in the sizing tables of Section (7.0).
This method allows full use of the maximum flow capacity of CSST. In this fashion, a designer can minimize piping size (or max-
imize flow capacity) with greater accuracy in a more complicated arrangements.
Sizing for a "Hybrid System", Black Pipe and CSST, is accomplished by using the "Summation Method" to determine the pressure
loss through each section of piping. Refer to table (7.4), "Pressure Drop Curves for Gastite CSST" and table (7.5.1), "Capacity
of Natural Gas Piping".
The sizing tables used in this manual include losses for (4) 90 degree bends, and (2) end fittings. Tubing runs with larger num-
bers of bends and or fittings should be increased by an equivalent length of tubing to the following equation: L = 1.3 (N): where
"L" is additional length of tubing, and "N" is the number of additional fittings, or 90 degree bends.
3.2.2 Reference Data for Proper System Sizing
3.2.3 The Longest Run Method
a) For sizing each length of pipe, determine the total gas load for all appliances serviced by that section and the maximum dis-
tance in which that particular section delivers gas. The maximum distance includes overall length from the meter to furthest
appliance location serviced by that run.
b) Refer to Appendix "A" Capacity Tables for the maximum flow capacity of CSST at the required piping length

3.2.4 EXAMPLE 1 — SERIES SYSTEM — LOW PRESSURE (6 INCHES WATER COLUMN)
Figure (3-8) shows a typical single family installation with (3) appliances. The piping is arranged in series with a main run branch-
ing at the appliances. The utility company's supply pressure (downstream of the meter) is 6 inches water column (low pressure).
The designated pressure drop across the overall length from the meter to the furthest appliance is .5" w.c. The utility company
advises that the specific gravity of the gas delivered will be .60 and the energy content is 1 CFH = 1000 BTUH.

3.2.7 EXAMPLE 4 — MULTIPLE MANIFOLD SYSTEM :
Figure (3-11) shows a larger single family installation with (7) appliances. The piping is arranged in parallel with two distribution
manifolds branching CSST runs to supply the appliances. The utility company's supply pressure (downstream of the meter) is 2
PSI. The designated pressure drop across the overall length from the meter to the furthest pounds -to -inches regulator is 1.0 PSI.
Sizing of all appliance runs downstream from the pressure regulator is performed considering the length and load for each appli-
ance as in the previous example.
To size the elevated pressure trunk lines, use the Longest Run Method to determine the trunk line sizes by adding the distance
from the meter to the furthest regulator (trunk "A" + trunk "F"). This length is used to size both trunk lines. It important to note
that the total load of the system is passing through trunk "A" while only the load of the second manifold system is passing through
trunk 'T". Continue to size all appliance runs downstream of the pressure regulator in the same fashion as a single manifold sys-
tem.

3.2.8 EXAMPLE 5 — SUMMATION METHOD FOR SERIES SYSTEM — LOW PRESSURE (6 INCHES WATER COLUMN)
Figure (3-12) shows a typical single family installation with (3) appliances. The piping is arranged in series with a main run branch-
ing at the appliances. The utility company's supply pressure (downstream of the meter) is 6 inches water column (low pressure).
The designated pressure drop across the overall length from the meter to the furthest appliance is .5" w.c. The utility company
advises that the specific gravity of the gas delivered will be .60 and the energy content is 1 CFH = 1000 BTUH.
When using the "Summation Method" for gas pipe sizing, the sum of the pressure losses through each section of pipe should result
in a minimum 5" water column pressure delivered to the appliance inlet. (Pressures less than 5" w.c. may be sufficient for proper
appliance operation but should be reviewed with the manufacturers' input rating and the local administrative authority)

3.2.9 EXAMPLE 6 -HYBRID PARALELL SYSTEM- LOW PRESSURE
In this example, the piping is arranged in a parallel configuration with rigid steel pipe used for the main run from the meter to a
central distribution manifold and individual CSST runs to each appliance. The utility company advises that the supply pressure is
7in. WC and the specific gravity of the gas delivered will be 0.60 and the energy content is 1 CFH = 1000BTUH.
Sizing for a Hybrid System (one that includes both Iron Pipe and CSST) is accomplished by using the "longest length method" to
determine the pressure loss through each section of piping. Each segment of the piping system uses the appropriate sizing table
for that particular piping material. It is important to note that most typical natural gas appliances require a minimum inlet pressure
of 4.0 in. WC to operate properly.
Therefore, for this example, the Iron Pipe portion of the system will be sized for no more than a 0.50 in WC pressure drop and the
CSST portion of the system will be sized for no more than a 1.0 pressure drop. This will result in a maximum 1.5 in WC pressure
loss over the entire system and a 5.5 in WC pressure delivered to the most remote appliance.

4.1 General Provisions
a) Precautions must be taken to ensure any exposed CSST is not damaged or abused during building construction. All tub-
ing, fittings and hardware should be stored in a clean, dry location prior to installation.
b) Open ends of the tubing are to be temporarily plugged or taped closed prior to installation to prevent entrance of dirt, dust
or other debris.
c) The protective plastic jacketing should be kept in place as much as possible to protect the tubing from corrosive threats.
Contact with chemicals containing chlorides must be followed by thorough rinse and wipe dry. This includes fluxes used to
solder copper tubing and acid based cleaners used to wash masonry.
d) Protect tubing from contact with sharp objects.
e) Avoid stressing the tubing or fittings with tight bends, kinks, twists or excessive stretching. Refer to table (4-1) for the rec-
ommended minimum bend radius for CSST.
f) Supporting CSST - Tubing shall be supported in a workmanlike manner with metal pipe straps, bands or hangers suitable
for the size and weight of the tubing, at intervals not to exceed those shown in table (4-2). Gastite, recommends the use of
metal pipe straps because some plastic clips are susceptible to breakage upon subsequent handling.

4.2 Fitting Assembly
Step 1
Step 2
Cut -to -Length
Cut tubing to the desired length leaving approximately one inch for fitting attach-
ment. Cut should be centered between two corrugations. Use light roller pressure
with extra rotations in one direction to leave tubing round and free of burrs. Note:
To ensure a quality flare, all cuts should be made on a straight section of tubing.
tri acket
Using a utility knife, strip jacket back to the valley of the second convolution.
Caution: Tube ends are sharp, use care when handling.
Step 3
Install Nut and Bushinigs
Thread fitting body into appliance. Slide nut over tubing. Separate bushings and
position as shown into the valley of the first convolution leaving one convolution
exposed between the end of the bushing and tubing.
At this point, the bushings will begin to capture the jacket for a contaminant resis-
tant seal.

Section 4.0 Installation Practices
Step 4
�i Position Bushings
Insert bushings into fitting body. A small amount of resistance indicates the bush-
ings are being compressed to further capture the jacket. Note: The piloting fea-
ture of the bushings ensures the tubing is aligned properly with the fitting body for
a uniform flare and a gas tight seal.
Fig. 4-7
Step 5
Wrench Fitting
Slide nut over bushings and thread onto fitting body. Some resistance will be
experienced as the nut begins to compress the tubing and create the double wall
flare.
Continue to thread the nut until resistance to wrenching increases greatly and the
double wall flare is tightly seated.
Note: During the tightening process rotate the nut only, do not rotate the fitting
body. For recommended torque values refer to table (4-3).

Support shall be at every floor not to exceed 10 feet between supports. Inside Hollow Wall Cavities. This is the preferred for ver-
tical sections of piping rather than horizontal sections. Avoiding horizontal runs through the walls will minimize the need for strike
protection.
4.3.2 Horizontal Runs
Tubing routed on top of sealing joists and other structural members which comply with the horizontal support spacing require-
ments will be considered sufficient supported without the need for strapping or tie downs. Beneath Floor Joists Gastite®, may be
routed beneath, through and along side floor and ceiling joists. Due consideration must be given to future construction possibil-
ities. Alternate locations such as between supply and return air ducts also provide protection. On top of Ceiling Joists is the pre-
ferred method of routing in areas where slab -on -grade construction is prevalent.
4.3.3 Installation clearance holes
Clearance holes for routing CSST are to be approximately 1/2 inch greater than the O.D. of the CSST. Drilling of any structural
member must be in conformance with the local building code. Refer to table (4-4) for the recommended drill hole sizing.

4.3.4 Concealed Fittings
G� e'
m
The Gastite® Mechanical Fittings have been tested and listed per the requirements of ANSI/IAS LC -1 for concealed use. The fit-
ting may be used for concealed attachment to appliance valves, branch runs using tee fittings, length splices and stub -outs man-
ufactured from approved fuel gas piping materials.
These guidelines address some of the most common situations where concealing the fittings is the only practical alternative.
These guidelines cannot address all applications of concealed fittings, but instead, provide typical instructions to demonstrate
the principles that apply to fittings listed for installation in concealed locations. (reference National Fuel Gas Code, NFPA 54, Sec-
tion 3.4.2)
a) New Installations - When multiple gas outlets are supplied from a single run
of CSST, each downstream outlet branch can be connected to the main run
using a tee -type fitting which can be located in a concealed location.
b) Fireplace "key valves" - Flexible piping connections to fireplace key valves
can be located in a concealed location, when accessibility is not readily pro-
vided.
c) Stub -outs — Flexible piping connections to stub -outs fabricated from
approved fuel gas piping materials.
d) Exclusion - Manifold stations (2 PSI system), which include the multi -port
manifold, shut-off valve and pressure regulator, shall not be installed in con-
cealed locations regardless of the qualifications of the tubing.
4.3.5 Modifications to Existing Systems
a) New Ceilings in Unfinished Rooms/Basements - CSST fittings originally
installed in accessible ceiling locations can be concealed in the event a ceil-
ing is installed at a later date
b) Extensions to Existing Tubing Runs - A concealed tubing can be modified to
permit an extension to another appliance location provided there is suffi-
cient capacity to supply both appliances at the same time. If an accessible
location for the modification is not available, the existing tubing run can be
modified with a tee fitting that will result in a concealed fitting behind the
wallboard.

4.3.6 Outdoor
Gsy e'
m
Gastite® Flexible Gas Piping has passed all requirements of ANSI/IAS LC -1, which include testing for suitability for exposure of
CSST piping systems to outdoor environments.
a) Outdoors - When installed outdoors, the external jacketing shall remain intact as much as practical for the given instal-
lation. Any portions of the exposed stainless steel tubing shall be wrapped with tape or sleeved to prevent later threats
by acid or chloride based cleaning solutions for masonry. Self -bonding silicone tape is recommended here for durabili-
ty
b) Along side a structure - When installed along the outside of a structure (between the ground and a height of 6 ft.) in an
exposed condition, the CSST shall be protected from mechanical damage inside a conduit or chase. A conduit or chase
is not required if the tubing is installed in a location that will not subject the CSST to mechanical damage.
4.3.7 Fire Rated Constructions
The plastic jacket on the steel tubing has an ASTEM E84 rating of 25 for flame spread, and 20 for smoke density. These values
meet most typical requirements for building construction. Therefore, the jacket should remain intact when passing through typi-
cal building constructions such as floor and ceiling joists, rim joists, walls or other fire rated resistance construction, limited to
materials of ASTM E84 ratings of 25 flame, and 50 smoke, or lower.
For tubing passing through a UL® classified fire rated construction, the UL®, Classified System for 'Through -Penetration Firestop
Systems (XHEZY is to remove the plastic jacketing for two feet on both sides of the wall and completely seal around the tubing
(jacket removed) with an approved fire rated caulk appropriate for the wall construction. The caulk must fill the entire annular
space around the tube circumference between the stainless tubing and wall. Completely fill nominal 1 1/4" deep opening in wall-
board layers on each side of assembly. Only 1 length of CSST may pass through a single penetration.

4.4 Protection
G e'
m
Concealed Gastite CSST should be routed in areas that will minimize the opportunity for physical damage or installed in areas
where the tubing will be free to move to avoid a potential puncture threat.
Gastite CSST installed in locations subject to physical damage shall be adequately protected. The tubing shall be protected at
points of support and when passing through structural members such as studs, joists and plates. The following (3) conditions
must exist to determine the need for mechanical strike protection.

4.5 Meter
Gastite-
^system
The gas piping for the meter "stub -out" is usually subject to local requirements such as size, location, and material type. It is
always important to confirm local code and utility requirements. Gastite recommends the use of 1/2" CSST or greater as
the minimum trunk line size. Size 3/8" should not be used for trunk lines. This will allow for the addition of future gas
appliances and minimize the opportunity for whistling.
a) Unsupported Meters - Meters that depend on the service supply line and/or the house piping for support shall not be
directly connected to the CSST. As shown in figures (4-28,4-29), a rigid connection point is created using a Gastite ter-
mination fitting, Gastite designed stub -out or rigid pipe components.

Self -Supported Meters - Meters that are independently supported with a bracket can be directly connected to the CSST
as shown in figure (4-30,4-31). If practical, direct CSST connections shall include a 3 to 6 inch loop of tubing (see fig-
ure 4-31) to accommodate differential settling and meter movement. No mechanical protection of the tubing is required
for outdoor meter connections, however, ensure that the local utility supports this practice as some utilities have regu-
lations specifying meter attachments. Ensure that any exposed sections (jacket removed) of the stainless tubing at the
fitting are wrapped with tape. This is especially important with masonry constructions.

4.6 Appliance
f
4.6.1 Moveable Appliance
a) The Gastite termination fitting or appliance stub -outs eliminate the need for concealed fittings by allowing CSST to be
routed to the exterior of a wall or floor to provide a fixed connection point (stub -out). This fixed connection point allows
for the attachment of flexible appliance connectors to moveable appliances such as dryers and ranges.
Fig. 4-32
b) An "Extended Termination Fitting" may be used for applications (stone,
brick, stucco, shingles, etc.) where it is difficult to mount the fitting direct-
ly to the exterior surface.
c) The "Appliance Stub -Out", is mounted to a stud face (fig.4-35) and pro-
vides a fixed point to which a Gastite mechanical fitting may be attached.
The design of this stub -out ensures that the flexible tubing is routed away
from any points of constraint that may subject the tubing to potential
puncture threats. All appliance stub -outs are designed with a 1/2" male
pipe thread end and the option of a 1/2" or 3/4" female pipe thread end
for attachment to the Gastite mechanical fitting.
d) The Straight Stub provides a fixed point for the Gastite mechanical fitting
and a stable platform for service meter connections. The Straight Stub
may be mounted to the face of a stud (fig.4-36) or mounted to an option-
al Stub Bracket with supplied self -drilling metal screws. The optional
bracket is designed to span typical stud construction as depicted in
(fig.4-7). The compact design of the straight stub allows for multiple stub -
outs within the stud cavity.
The Straight Stub may also be used to pass through joist and wall con-
structions (fig.4-38). It is important to follow all requirements for sleev-
ing when passing through masonry construction.

CSST should not be used inside the firebox for log lighters/gas wands or
in any firebox where wood logs will be burned due to the potential for phys-
ical harm to the tubing.
Gastite® mechanical fittings are approved to be concealed and can be connected
directly to a valve controlling gas flow to a fireplace appliance. The CSST and valve
connection can be installed behind the wall, beneath the floor, hearth, or behind the
brickwork of the fireplace.
Where it is necessary to install Gastite® through sheet metal enclosures such as
gas fireplaces, and vibration from motors could cause mechanical wear, the plas-
tic jacket should remain intact and the tubing should be routed or supported to pre-
vent direct contact with the enclosure. If direct contact can not be avoided, protec-
tion such as grommets, metal conduit or rigid pipe may be used. Materials used for
protection in fire rated constructions must be appropriate for the application. Remove
the plastic jacketing only on the portion of CSST that may be exposed to the flame
within the firebox.

4.7 Manifold
Manifolds are installed where multiple runs are made from a common location in a parallel arrangement. The manifold may be
manufactured from a one piece malleable iron or brass casting, a welded fabrication of steel sub -components or an assembly of
approved, malleable iron tees and short nipples.
Depending on the location and available space, different mounting arrangements are permitted. A manifold may be mounted on
the surface of an interior wall, between open floor joists, in attic spaces, crawl spaces, within a partition wall, or inside an enclo-
sure.
The installation of manifold assemblies using a pounds -to -inches regulator must be in accordance with all local codes, and the fol-
lowing guidelines:
a) A manifold assembly utilizing a pounds -to -inches regulator shall
be installed in an accessible, ventilated location so that the reg-
ulator can be inspected, maintained and serviced if repair or
replacement is required.
b) For manifold systems that use a pounds -to -inches regulator
installed behind an access panel, all tubing penetrations in the
cabinet should be sealed, caulked or grommeted. The cabinet
must be ventilated through the panel/door and not into a wall
space.
c) Open face cabinets, which communicate with the normal room
environment, may be utilized without the need for ventilation or
penetration sealing requirements.

4.8 Pressure Regulator f
4.8.1 Description "
a) A CSST system utilizing gas pressures exceeding 1/2 PSI shall include a regulator to limit downstream appliance supply
pressure to 1/2 PSI or less. The regulator shall have a lock-up feature that will limit the downstream pressure to 1/2
PSI.
b) The Maxitrol and OARA regulators supplied by Gastite are designed to supply the highest performance as both Line Pres-
sure Regulators and Gas Appliance Regulators. They feature precise regulating control from full flow down to pilot flows.
They can be used as a single stage regulator, reducing pounds pressure to normal burner pressure. They can also be
used as a line regulator on equipment already fitted with an appliance regulator.
c) The materials of all component parts are carefully selected and corrosion resistant. The housing are made of durable
die cast aluminum, the diaphragm and self—aligning valve seat are made of nitrile rubber which is selected to work at
ambient temperatures of —40 to 205 degrees F (40 to 96 degrees C). All regulators are supplied with vent limiting

:..
The Maxitrol and OARA Regulators are typically used in a 2 or 5 PSI gas piping installation to reduce supply pressure to the appli-
ance within required operating ranges (typically 4" — 7" W. C. natural gas or 10" — 11" LP gas)..
For natural gas, the regulator outlet pressure is set to 8" w.c. and the appliance runs are sized with a 3"w.c. pressure drop. This
will allow for 5"w.c. inlet pressure at the appliance. For propane gas, the regulator outlet pressure is set to 11"w.c and the appli-
ance runs are sized with a 0.5" w.c. drop. This will allow for a 10.5" w.c. inlet pressure at the appliance.
To select the correct regulator for pressure regulation, the following information must be established:
• Available inlet pressure range at the regulator inlet
• Desired outlet pressure
• Required maximum flow rate
• Desired inlet pressure at the gas appliance
• Refer to tables on the next page to select the correct regulator to satisfy system requirements.

Gast4te-
system
In the following example, a line regulator is required in a natural gas 2 -PSI gas piping system. The appliances are rated to oper-
ate at 4" - 7" w.c. to the inlet of the appliance regulator/control. A pounds -to -inches regulator is required to reduce pressure to
specification with a total flow requirement of 196 CFH (196,000 BTUH natural gas with a 0.60 specific gravity.
The 2 -PSI "trunk" line (meter -to -regulator) is sized with a maximum
pressure drop of 1 PSI along its length (per the appropriate sizing
chart). Therefore, under full flow conditions, there will be a mini-
mum of 1 PSI at the inlet of the line regulator. With a 1 PSI inlet
pressure and a pressure drop across the regulator of 1/2 PSI, the Meter
line regulator will flow 250 CFH. If a higher regulator flow capacity
is desired, the available pressure at the regulator inlet must be
increased to allow for a higher pressure drop across the regulator
or a larger regulator may be selected.

Section 4.0 Installation Practices
4.8.3 Installation
a) The regulator shall be installed in an accessible location with an approved shut-off valve on the inlet side and a union (if
required by code) on the outlet side so that it may be inspected, maintained and serviced if repair or replacement is
required
b) The regulator is suitable for multi -poise mounting. When using a vent -limiting orifice however, the regulator must be
mounted in a horizontal upright position. All regulators provided by Gastite®, include a vent- limiting orifice.
c) The vent -limiting orifice is a fail-safe device that permits free air l
movement above the diaphragm during normal operation. In the
unlikely event of a diaphragm rupture, the vent limiting orifice will
limit gas escapement to 1.00FH natural gas at 2 PSI and 0.65 Check Boll
CFH LP at 2 PSI. Both values are below the ANSI standard of 2.5
CFH. Note: The vent -limiting orifice does not allow gas to
escape to the environment during operation.
Normal Mode Fal Safe Mode
Fig. 4-60
d) Do not leak test the vent orifice with liquid leak test solution. This action will contaminate the internal ball check mech-
anism or plug the breathing hole resulting in erratic regulator performance
e) When using a vent -limiting orifice, the maximum inlet pressure is (2 PSI Propane) and (5 PSI Natural Gas).
f) When using a vent line, the line must be at least the same size as the regulator vent connection, and cannot exceed a
length of 30 ft. The vent shall be designed to prevent entry of water, insects or other foreign materials that could cause
blockage of the line. Do not vent to appliance flue, pilot light or building exhaust system.
g) The OARA regulators and the Maxitrol series regulators have a lower temperature limit of -40 degrees F. The lower tem- .
perature limit and rust proof construction design enables the regulator to be used for outdoor installations. To minimize
the potential for moisture condensation and freezing problems in or around the vent port, the vent -limiting orifice must
be removed for outdoor installations.
Outdoor Mounting Options:
The regulator may be mounted upside down with the open vent port facing down. Consideration must be taken to ensure
there is adequate clearance for snow buildup.
The regulator may be mounted horizontally, with a vent tube installed in the venting port. The end of the tube must be
facing downward, and should be designed to prevent water and foreign material from causing a blockage. Another alter-
native is a outdoor plastic vent protector designed for the regulator

Section 4.0 Installation Practices
4.8.4 Performance
u
a) A performance test should be conducted while operating all appliances at full load. This will test if adequate pressure
is reaching each appliance under full -load conditions. To accomplish this, measure the line pressure at the appliance
connection while operating the appliance.
b) The inlet pressure for a typical gas appliances under full load conditions should measure a minimum of 4 inches of water
column pressure for natural gas and a minimum 10 inches water column pressure for propane. If these pressure ranges
cannot be obtained, a slight adjustment to the service regulator or the pounds -to -inches regulator may be necessary to
increase line pressure.
4.8.5 Adjustment
a) Adjustment can be accomplished by first removing the regulator seal cap to expose the adjusting screw. Turning the
screw clockwise will increase outlet pressure, turning it counter -clockwise will decrease pressure.
b) If spring adjustment will not produce the desired outlet pressure, check to make sure the main supply pressure is ade-
quate. If the main supply pressure is adequate, consult factory for other line -regulator options. Do not continue to turn
regulator adjusting screw clockwise if the outlet pressure readings do not continue to increase. This may result in
over -firing due to loss of pressure control, should there be a subsequent increase in inlet pressure.
c) The 2 PSI system pounds -to -inches regulator can be adjusted with an outlet pressure ranging between 7 to 9 inches
water column pressure for natural gas and 10 to 12 inches water column for propane. The regulator must be adjusted
according to the manufacturers recommended procedure. A pressure gauge mounted just downstream of the regulator
can monitor the set pressure under various loads.
d) The regulator is pre-set and labeled at the factory for either natural gas or propane. The average natural gas appliance
is designed to operate at 3 to 4 inches water column pressure, and a pressure difference of 1 to 2 inches of water col-
umn across the appliance regulator which will prevent slow regulator response. Thus, the appliance regulator will oper-
ate best at 4 to 6 inches w.c. inlet pressure. The Pounds -to -Inches system regulators for Natural Gas are set to deliver
8 inches of W.C. outlet pressure under load to allow for 3 inches of W.C. pressure drop in the tubing.
e) The average propane gas appliance is designed to operate at 10 to 10-1/2 inches water column pressure. Thus, the
Pounds -to -Inches regulators for Propane Gas are set to deliver 11 inches water column outlet pressure under load to
allow for 0.5 inches water column pressure drop in the tubing.
4.8.6 Over -pressurization Protection
Down stream over -pressure protection measure must be observed in any gas piping installation where a line -pressure regulator
is utilized for pressures in excess of 2 psi to supply appliances rated for 1/2 psi or less inlet pressure. An additional appliance
regulator of suitable control and capacity may be installed immediately downstream of the line regulator (piggyback) or immedi-
ately in front of each appliance control. This additional regulator is redundant and provides over -pressure protection (OPD) in the
event of the line regulator fails.
NOTE: When using regulators other than those specified by Titeflex for use with the Gastite system, careful con-
sideration must be given to the regulator performance characteristics such as required inlet pressure, flow capac-
ity, the pressure drop through the regulator and available outlet pressure.

Section 4.0 Installation Practices
4.9 Underground Installations
a) CSST shall not be buried directly in the ground or directly embedded in concrete( e.g., patio slabs, foundations and walk-
ways). When it is necessary to bury or embed CSST, the tubing shall be routed inside a non-metallic, watertight conduit
that has an inside diameter at least 1/2 inch larger than the O.D. of the tubing. For ends of the conduit installed out
doors, the conduit shall be sealed at any exposed end to prevent water from entering. No mechanical joint fittings
are permitted within the conduit.
b) Venting of the conduit has typically been required because
the use of conventional materials such as rigid pipe has usu-
ally resulted in some form of connection or union within the
conduit. Unlike rigid pipe however, CSST is continuous with
only one fitting at each end of the run, and no fittings inside
the conduit. As a result, the possibility of gas build-up due to
fitting leaks has been eliminated. Therefore, Gastite does not
require the sleeving to be vented to the outside of the struc-
ture, Fig. (4-64).

bonded to any grounding electrode, as defined by the National Electrical Code, ANSI/NFPA 70." When a bonding clamp is
required it must be attached to the Gastite brass fitting adapter, a steel manifold, or to a rigid pipe component connected to a
Gastite fitting. The corrugated stainless steel portion of the gas piping system SHALL NOT be used as the bonding attachment
point under any circumstances.

5.2 Installation Checklist Description
Corrugated Stainless Steel Tubing (CSST) has been design certified by the American Gas Association Laboratory since 1990 for
use as a fuel gas piping system. CSST has been tested per ANSI/IAS LC 1 as required for approval and is listed as an approved
gas piping material in the National Fuel Gas Code-NFPA 54, BOCA National Mechanical Code, SBCCI Standard Gas Code, and the
new International Code Series. Gastite, is a listed product with IAPMO and pursuant to section 302.1 Alternate Materials and Meth-
ods of the Uniform Plumbing Code, may be installed with approval from the local administrative authority.
Approval: Conditions and Requirements
A flexible gas piping system using CSST must be installed in accordance with all local building codes and the manufacturer's
instructions. The following checklist is designed to assist the local administrative authority to perform an inspection of a fuel pip-
ing system using corrugated stainless steel tubing.
1. Flexible Gas Piping may only be installed by a Qualified Installer who has successfully completed the manufacturers
Certification Training Program. A manufacturer's certification card is required to purchase and install Flexible Gas Pip-
ing.
2. Only the components provided or specified by the manufacturer (including strike protection) as part of the piping sys-
tem are to be used in the installation.
3. CSST routed in a location which is concealed, constrained and within 3 inches of a potential threat will be protected
against damage by protection devices listed in the manufacturers Design and Installation Guide.
4. Sizing of the Flexible Gas Piping System must be performed using capacity tables found in the manufacturer's Design
and Installation Guide or other code approved CSST capacity tables.
5. CSST should not be connected to moveable appliances. Connections to moveable appliances such as ranges and
clothes dryers should be accomplished with a "flexible appliance connector".
6. The Flexible Gas Piping System must be pressure tested for leaks during rough construction in accordance with all
local codes. In the absence of local requirements, test in accordance with NFPA 54, National Fuel Gas Code, which
is 1-1/2 times the maximum working pressure but not less than 3 PSI. To subject the entire CSST system to pres-
sure test, the pressure regulators should be isolated or removed.
7. Regulators are suitable for multi -poise mounting. When using a vent -limiting device however, the regulator must be
mounted in a horizontal upright position.
8. A manifold assembly utilizing a pounds -to -inches regulator shall include a ball valve ahead of the regulator and installed
in an accessible location so that the regulator can be inspected, maintained and serviced if repair or replacement is
required.
9. When installed outdoors, the external jacket shall remain in tact as much as possible. Exposed portions of the stain-
less steel tubing shall be wrapped to provide protection from corrosive threats.
10. For installation buried underground, concrete/asphalt or embedded in concrete, CSST must be routed in a non-metal-
lic watertight conduit which has an inside diameter at least 1/2 in. larger than the outside diameter of the tubing.
For under concrete/asphalt slab, sleeved CSST must be buried in accordance with all local codes. No mechanical
joints are permitted within the conduit.

5.3 Repair of Damaged CSST
5.3.1 Determine Damage
Crushed, dented or kinked tubing may result in restricted flow conditions. Use the following guidelines to determine the severi-
ty of damage and whether repair or replacement is necessary.
a) CSST gas tubing must be repaired if damaged by puncture of any kind, i.e. nails, screws, drill bits, etc.
b) No repairs or replacement of the tubing is necessary if the CSST tubing is only slightly dented due to impact or crush-
ing and the overall crush depth is less than 1/3 the diameter of the tubing. Minimal flow reduction will occur at this lim-
ited damage level.
c) Repair or replacement is necessary if the overall crush depth is greater than 1/3 the diameter of the tubing. Restricted
flow may occur at this damage level
d) CSST tubing bent beyond its minimum bend radius so that a crease or kink remains. Restricted flow may occur at this
damage level
5.3.2 Method of Repair
A line splice can be made, but if the tubing run is short and easily accessible, the preferred repair method is to replace the entire
length. Often, a tubing run can be replaced faster than repairing the damaged section. The Gastite® mechanical joint fittings can
be removed and easily re -attached. This is the preferred method because it does not add any additional fitting joints to the sys-
tem.
Where repairs or replacements involve only the Gastite® CSST, the tubing can be joined with standard pipe couplings or the
�. Gastite® CSST coupling.
Where repairs or replacements involve CSST systems of different manufacturers, the systems can be joined through standard
pipe couplings and each manufacturer's recommended CSST fitting.

Section 6.0 Pressure / Leakage Testing
Section 6.0 Pressure/Leakage Testing
6.1 General Guidelines for Pressure Testing
a) The final installation must be inspected and tested for leaks in accordance with the local/state codes. In the absence of
local codes, installation must be in accordance with the current edition of the National Fuel Gas Code, ANSI
Z223.1/NFPA-54 (USA), or Installation Codes CAN/CGA-B149.1 & B149.2 (Canada). Pressure testing must comply with
these guidelines or local codes. When local codes are more stringent, local codes must be followed.
b) Pressure testing must be performed during rough construction of the facility (before interior walls are finished). This will
permit a more complete inspection of the piping system during the pressure testing.
c) Do not connect appliances or pressurize with fuel gas until after the pressure has been passed.
d) All gas outlets for appliance connections should be capped during pressure testing.
6.2 Elevated Pressure Systems
A 2 PSI system usually requires a pressure test of 10 PSI or greater, depending on local code. In this case, the regulator must
be removed or isolated prior to pressure testing.
The test may be performed as a one -part test replacing the regulator with suitable "jumper" pipe length for pressure testing the
entire system. After the pressure test, the regulator is installed and the remaining connections are leak tested with a chloride free
bubble solution.
Fig. 6-1 Fig. 6-2
Or a two-part test may be performed as shown in figure (6-3)
• The first test is performed on the elevated pressure section, between the meter con-
nection and the pounds -to -inches house line regulator.
• The second test is performed on the low-pressure section, between the outlet of the
pounds -to -inches house line regulator and the gas appliance outlets.
• For a "two-part" test, it is important to remember to close both gas "shut-off" valves to
avoid damage to the regulator.
Fig. 6-3
Most jurisdictions also require an additional pressure or leakage test performed after the construction is completed and finished
interior walls are in place. The leakage test procedure is generally performed by the gas utility at the time of setting their meter.
This test is performed to assure no damage was done to the tubing during the closing -in construction process, and is typically
required before gas service is initiated.

Section 6.0 Pressure / Leakage Testing
6.3 Appliance Connection Leakage Check Procedure
After the final pressure test, inspection and final construction is complete (finished interior walls) connect the appliances to the
tubing system. This connection can be made using a stainless steel flexible connector for movable appliances such as a dryer
or range, or with CSST tubing, or rigid black pipe for fixed appliances. Turn the gas on at the meter and inspect for leakage
before operating the appliances.
a)
A
Connections made at the appliances should be leak checked with a chloride -free bubble solution.
Before placing the appliances in operation, the tubing system should be purged. This displaces the air in the system
with fuel gas. Be sure to vent into a well -ventilated area.
NOTE: Leak test solutions may cause corrosion to some types of material in the gas tubing system, be sure to water rinse after
the test and thoroughly dry all contacted material. Also, the vent limiter should not be leak tested with a liquid test solution. This
will contaminate the internal ball check mechanism or plug the breathing hole, resulting in erratic regular operation.

Table 7-18
Specific Grivify Factor far Natural S'
Gas piping systems that are to be supplied with gas of a specific gravity other than 0.60 shall apply a specific gravity factor. The conversion
is accomplished by multiplying the capacities given in the Tables, Charts and Graphs by the appropriate multiplier from the table below. In
case the exact specific gravity does not appear in the table, choose the next higher value shown. Check with the local gas utility or supplier
for the correct specific gravity.
Options:
1. Using Table A-5 the flow capacity of 1/2" CSST at 50 ft, for natural gas with a specific gravity of 0.60 is 266 CFH. At a specific
gravity of 0.65 the resultant value in the table will be 255 CFH (266 x 0.96).
or
2. A furnace rated at 80,000 BTUH natural gas with a specific gravity of 0.60 will be rated at 76,800 BTUH natural gas with a spe-
cific gravity of 0.65 (80,000/0.96).

Section 8.0 Definitions
� Section 8.0 Definitions
APPLIANCE (EQUIPMENT) - Any device which utilizes gas as a fuel or raw material to produce light, heat, power, refrigeration
or air conditioning.
APPROVED - Acceptable to the authority having jurisdiction.
AUTHORITY HAVING JURISDICTION - The organization, office or individual responsible for "approving" equipment, an installa-
tion or procedure.
CAPACITY, FLOW - As used in this standard, the amount of a specified gas that will flow through a specific length and configu-
ration of tubing, a manifold, fitting or other component at a specified pressure drop in a fixed period of time.
CONCEALED GAS PIPING - Gas piping, which, when in place in a finished building, would require removal of permanent con-
struction to gain access to the piping.
CONNECTOR, GAS APPLIANCE - A factory -fabricated assembly of gas conduit and related fittings designed to convey gaseous
fuel, and used for making connections between a gas supply piping outlet and the gas to an appliance. It is equipped at each
end for attachment to standard taper pipe threads.
EQUIVALENT HYDRAULIC DIAMETER (EHD) - A theoretical size which reflects the hydraulic performance of the tubing. It is
not true physical measurement.
EXPOSED GAS PIPING - Gas piping which will be in view in the finished structure.
FUEL GAS - A commonly distributed gas used for fuel such as natural gas, manufactured gas, undiluted liquefied petroleum gas
1 (vapor phase only), liquefied petroleum gas -air mixtures of these gases (includes propane and butane).
GAS UTILIZATION EQUIPMENT - Any device that utilizes gas as a fuel or raw material or both.
INCHES OF WATER COLUMN ("W.C.) — Method of pressure measured in inches of water column by a manometer or pressure
gauge. Commonly used in the gas industry when the pressure is less than (1) PSI.
LISTED - Equipment or materials including a list published by an organization acceptable to the authority having jurisdiction and
concerned with product evaluation that maintains periodic inspection of production of listed equipment or materials and whose
listing states either that the equipment or materials meets appropriate standards or has been tested and found suitable for use
in a specified manner.
LOCKUP PRESSURE, REGULATOR - The system pressure, immediately downstream of the regulator, at which the regulator
valve will completely close (leak tight) under no -flow conditions to prevent the downstream pressure from exceeding a predeter-
mined level.
MAXIMUM ACTUAL OPERATING PRESSURE - The maximum pressure existing in a piping system during a normal annual oper-
ating cycle.
PIPING SYSTEM - As used in this standard, an assembly of corrugated stainless steel tubing and tubing connection fittings,
intended for field assembly and installation in residential or commercial buildings to distribute fuel gas to gas utilization equip-
ment within the building. The piping system may also include a gas pressure regulator(s), a shutoff valve(s), tube shielding
devices, distribution manifold(s), and other approved devices or components.
PRESSURE DROP - The loss in static pressure of flowing fuel gas due to friction or other flow resistance in tubing, fittings,
valves, regulators, or other devices in the piping system.
N QUALIFIED INSTALLER - Any individual, firm, corporation or company which either in person or through a representative is
engaged in and is responsible for the installation or replacement of building gas piping systems, who is experienced in such work,
familiar with all precautions required, and has complied with all the requirements of the authority having jurisdiction.

Section 8.0 Definitions
QUICK -DISCONNECT DEVICE - A hand -operated device which provides a means for connecting and disconnecting an appliance
or an appliance connector to a gas supply, and which is equipped with an automatic means to shut off the gas supply when the
device is disconnected.
REGULATOR, PRESSURE - A device placed in a gas line for reducing, controlling and maintaining the pressure in that portion
of the piping system downstream of the device.
SHIELDING DEVICE - A component of the piping system used to protect the installed corrugated tubing from accidental punc-
ture by nails, screws or similar hardware at concealed tubing support points.
STRIKER PLATE - A special type of shielding device used when concealed tubing is run through wall studs, floor and ceiling joists
or other structural members where tubing movement is restricted.
VALVE, SHUTOFF - A device used in piping to control the gas supply to any section of the piping system or to an appliance
