Remember:

When a conflict exists between the Pro-Flex Installation Guide and local requirements, the local codes take precedence. The installation must be made in accordance with local codes, or in the absence of local codes, in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54; Natural Gas and Propane Installation code, CSA B149.1 in Canada; the International Fuel Gas Code; the Federal Manufactured Home Construction and Safety Standard, 24 CFR Part 3280; the Manufactured Housing Construction and Safety Standards, ICC/ANSI 2.0; or the Standard on Manufactured Housing, NFPA 501; as applicable. Pro-Flex, LLC cannot guarantee that the local administrative authority will accept the most recent version of these codes. It is the ultimate responsibility of the qualified installer to determine suitability and acceptance of any building components including gas piping. Pro-Flex® LLC assumes no responsibility for labor or material for installations made without prior determination of local code authority acceptance.
