Proper grounding and bonding may reduce the risk of damage and fire from a lightning strike. Lightning is a highly destructive force.
Even a nearby lightning strike that does not strike a structure directly can cause metallic systems in the structure to become
energized. If these types of systems are not properly bonded,the difference in potential between the systems may cause the
charge to arc from one system to another system. Arcing can cause damage to CSST. Bonding and grounding as set forth above
should reduce the risk of arcing and related damage.
Depending upon conditions specific to the location of the structure in which the WARDFLEX°system is being installed,including
but not limited to whether or not the area is prone to lightning,the owner of the structure should consider whether or not a lightning
protection system is necessary or appropriate. Lightning protection systems are beyond the scope of this bulletin, but are covered
by NFPA 780,which is the Standard for the Installation of Lightning Protection Systems,and other standards.
4.11 MANUFACTURED HOUSING GUIDELINES
A. CODE AND ADMINISTRATIVE REQUIREMENTS
1. Manufactured homes and mobile homes bearing an insignia or required to bear an insignia must comply with Title VI 24 Code
of Federal Regulations,The National Manufactured Housing Act of 1974 Part 3280. In most jurisdictions this requirement
remains in force when the structural,electrical plumbing or mechanical systems are altered. The Code of Federal Regulations,
Housing and Urban Development,Part 3280 Manufactured Home Construction and Safety Standards is applicable throughout
the USA for manufactured housing construction(also known as "HUD code" housing).
2. There are other types of factory-built housing that do not fall directly under the classification "HUD code"which must also be
reviewed for special installation considerations when designing a CSST gas piping system or appliance retrofit. Some
examples of this type of housing are Assembly Buildings, Panelized,Modular,and Production Build.WARDFLEX°should not be
considered for RVs,which are subject to over the road use and not just initial placement or repositioning.
3. Part 3280 Manufactured Home Construction and Safety Standards 1994 has not been revised or updated for several years.
There has been an effort by both NFPA and CABO (now a part of the ICC)to have the US Congress adopt a new Manufactured
Housing Code. The latest version of the CABO Code ICC/ANSI 2.0 Manufactured Housing Construction Safety Standards is
available but has not been adopted by Congress.
4. Ward Manufacturing LLC,has obtained a written opinion from the U.S. Department of Housing and Urban Development
regarding the use of WARDFLEX CSST. This HUD decision states "CSST,such as WARDFLEX,is allowed to be used in HUD
manufactured homes(based upon incorporation of NFPA 54-1992 ANSI 223.1 the National Fuel Gas Code into Section 3280.703
Minimum Standards)."This opinion shall be confirmed with State authorities responsible for inspections of HUD Code buildings
prior to installing WARDFLEX after the home has left the factory. For factory installations,approval by the DAPIA
(Manufacturer's Design Approval Primary Inspection Agency)is normally required for the piping system design. Contact Ward
Manufacturing for specification data and a copy of the HUD decision letter.

4.9 UNDERGROUND INSTALLATIONS
WARDFLEX°may not be directly buried or directly embedded in or under concrete slabs. WARDFLEX°may be installed under-
ground or in/under a concrete slab when routed through previously embedded,non-metallic,watertight conduit such as PVC pipe.
Conduit used to protect WARDFLEX°CSST,when installed underground, must have an I.D.%z" larger than the O.D of the CSST.
For outdoor underground installations,the annular space between the CSST and the conduit must be sealed to prevent entrance of
moisture,dirt,debris, and insects. The use of a mechanical joint,coupling, or tee is prohibited inside the conduit.
For indoor buried installations,Ward Manufacturing does not require the conduit to be vented to the outside. Due to its continuous
construction and availability in long run lengths,no fittings are required/permitted inside the conduit. This eliminates the possibility
of gas build up caused by leaking fittings after the system has been placed in service. In the event that local code requires the
conduit to be vented,the use of a tee designed for use with non-metallic conduit may be placed at the termination end of the
conduit.One end of the tee should be sealed while the other outlet can be used to connect a vent line that is routed outside(figure
4.44). Vent lines routed to the outside of a structure must be installed in such a manner to prevent entrance of moisture,dirt,debris,
and insects.
Burial Depths:
• Outdoors—minimum of 12"
• In slab—1-1/2" minimum concrete coverage.
• Under slab—no minimum burial depth below slab or in compliance with local codes.
Conduit Termination Height:
• Indoors—Conduit to extend a minimum of 1" above finished floor height.
• Outdoors—Conduit to extend a minimum of 4" above finished grade.
4.10 WARDFLEX® CSST Electrical Bonding
Direct bonding is required for all natural and LP gas piping systems incorporating WARDFLEX°CSST whether or not the piping
system is connected to an electrically powered gas appliance. Direct bonding is included as part of the manufacture's require-
ments for both single family and multi-family buildings.A person knowledgeable about electrical system design,local electrical
code,and these requirements should specify the bonding for commercial applications.
WARDFLEX°CSST installed inside or attached to the exterior of a building or structure shall be
electrically continuous and directly bonded, by a qualified person,to the ground system of the building.
The gas piping is considered to be directly bonded when installed in accordance with the following instructions:
• A bonding jumper is permanently and directly connected to the electrical service grounding system.
This can be achieved through a connection to the electrical service equipment enclosure,the grounded
conductor at the electrical service,the grounding electrode conductor(where of sufficient size)or to the one or
more grounding electrodes used.
• A single bond connection is made to the building gas piping downstream of the utility meter or second stage
regulator(LP systems),but near the gas service entrance(either outdoors or indoors)of the structure,or dow
stream of the gas meter of each individual housing unit within a multi-family structure.A"daisy chain" configuration
of the bonding conductor is permitted for multi-meter installations.A bonding connection shall not be made to the
underground,natural gas utility service line or the underground supply line from a LP storage tank.
• The bonding conductor is not smaller than a#6 AWG copper wire or equivalent.The bonding conductor is installed
and protected in accordance with the NEC.
• The bonding conductor is attached in an approved manner in accordance with NEC and the point of attachment for
the bonding conductor is accessible.
• Bonding/grounding clamp used is listed to UL 467 or other acceptable national standards.
• The bonding clamp is attached at one point within the piping system to a segment of rigid pipe or a pipe component
such as a nipple,fitting or manifold provided it is manufactured with an appropriate and Code listed material.
The bonding clamp must be attached such that metal to metal contact is achieved with the steel pipe component.
Remove any paint or applied coating on the pipe surface beneath the clamp.See Figures 1 and 2 for guidance.
The corrugated stainless steel tubing portion of the gas piping system shall not be used as the point of attachment
of the bonding clamp at any location along its length.
