5.2 Installation Checklist Description
Corrugated Stainless Steel Tubing (CSST) has been design certified by the Canadian Standards Association since 1990
for use as a fuel gas piping system. FlashShield™ CSST has been tested per ANSI LC1 as required for approval and as an
approved gas piping material in the National Fuel Gas Code-NFPA 54 & 58, the International Fuel Gas Code-ICC, and
with the Uniform Plumbing Code-IAPMO.
Approval: Conditions and Requirements
A flexible gas piping system using FlashShield™ CSST must be installed in accordance with all local building codes and the
manufacturer’s instructions. e following checklist is designed to assist the local administrative authority to perform an
inspection of a fuel gas piping system using corrugated stainless steel tubing.
1) FlashShield™ flexible gas piping may only be installed by a qualified installer who has successfully completed the
manufacturer's certification training program. A manufacturer’s certification card is required to purchase and install
FlashShield™ flexible gas piping.
2) FlashShield™ CSST routed in a location which is concealed, constrained and within 3 inches of a potential threat must
be protected against damage using protection devices listed in the manufacturer’s Design and Installation Guide.
3) FlashShield™ 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.
4) Regulators are suitable for multi-poise mounting. When using a vent-limiting device however, the regulator must be
mounted in a horizontal upright position.
5) e external protective jacket system shall remain intact on the CSST.
6) For installations buried underground, under concrete/asphalt or embedded in concrete, FlashShield™ CSST must be
routed in a non-metallic watertight conduit which has an inside diameter at least 1/2 in. larger than the outside diameter
of the tubing. Under concrete/asphalt slab, sleeved CSST must be buried in accordance with all local codes. No me-
chanical joints are permitted within the conduit.
7) Installation must be properly supported to not only keep the job professional and organized but also to prevent excess
strain on the bends and fittings. Supports installed in addition to the practices outlined by Gastite Division, restricts the
tubing and increases susceptibility to nail or screw strike damage.
8) Gas piping systems must be properly bonded to the structure's electrical service. A qualified professional following the
NEC approved methods as outlined in Section 4.10 shall perform the bonding installation.
