CSA ANSI LC 1:2016 pdf download.Fuel gas piping systems using corrugated stainless steel tubing.
1.1
CSA ANSI LC 1 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 CSA ANSI LC 1 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).
1.2
CSA ANSI LC 1 also applies to corrugated stainless steel piping systems in which portions of the piping are exposed to the outdoors as required to make connections to outdoor gas meters or to outdoor gas appliances, which are attached to, mounted on or located in close proximity to the building structure.
1.3
CSA ANSI LC 1 does not apply to CSST, whether coated or uncoated, intended for direct burial underground. Tubing is installed underground only when encased inside either an approved conduit or as part of an approved engineered system and in accordance with local codes and the manufacturer’s instructions.
1.4
CSA ANSI LC 1 includes criteria to establish the suitability of concealed mechanical tube fittings for use with concealed gas piping (see Clause 3, Definitions).
1.5
CSA ANSI LC 1 also applies to corrugated stainless steel piping systems that are used in conjunction with other approved fuel gas piping materials.
1.6
CSA ANSI LC 1 applies to piping systems rated at either 5 psi (34.5 kPa) and intended for exposure to maximum actual operating pressures (see Clause 3, Definitions) not exceeding 6.5 psi (44.8 kPa), or rated at 25 psi (172.5 kPa) and intended for exposure to maximum actual operating pressures not exceeding 30 psi (207 kPa). The manufacturer has the option to certify its system to either pressure rating.
1.7
CSA ANSI LC 1 applies to piping systems not exceeding a size of 2 inches (50.8 mm), based on the nominal inside diameter of the tubing.
CSA ANSI LC 1 does not apply to gas connectors for appliances. These connectors are covered by the
Standardfor Metal Connectors for Gas Appliances, and the Standard for Connectors for Movable Gas
Appliances, ANSI Z21.24 • CSA 6.10 and Z21.69 • CSA 6.16.
