Preface

This is the fifth edition of ANSI LC 1 / CSA 6.26, Fuel gas piping systems using corrugated stainless steel tubing. It supersedes the previous editions published in 2016, 2014, 2005, and 1997.

Scope

1.1
This Standard applies to fuel gas piping systems using corrugated stainless steel tubing (CSST), intended for installation in residential, commercial or industrial buildings, and including the following components as a minimum:

a) Corrugated stainless steel tubing (CSST);

b) Fittings for connection to the CSST; and

c) Striker plates (see Clause 3, Definitions) to protect the installed CSST from puncture threats.

Other components of piping systems covered by this Standard include gas manifolds, gas pressure regulators, manual gas valves, quick-disconnect devices and gas convenience outlets (see Clauses 4.3, Gas pressure regulators, 4.4, Manually operated gas valves and 4.5, Quick-disconnect devices and gas convenience outlets). If such additional components are required to complete the piping system installation, they are either provided as part of the piping system or specified in the manufacturer?s installation instructions [see Clause 4.7-m)].
