Preface

This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of connectors for outdoor gas appliances and manufactured homes. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on connectors for outdoor gas appliances and manufactured homes designed for utilization of gas. There are risks of injury to persons inherent in some appliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in this standard are intended to reduce such risks while retaining the normal operation of the appliance.

Nothing in this standard is to be considered in any way as indicating a measure of quality beyond compliance with the provisions it contains. It is designed to allow compliance of connectors for gas appliances and manufactured homes, the construction and performance of which may exceed the various provisions specified herein. In its preparation, full recognition has been given to possibilities of improvement through ingenuity of design. As progress takes place, revisions may become necessary. When they are believed desirable, recommendations should be forwarded to the Chairman of Accredited Standards Committee 221 /83, 8501 East Pleasant Valley Road, Cleveland, Ohio 44131, or the Chairman of the CSA Standards Steering Committee on Gas Burning Appliances and Related Accessories, 5060 Sprectrum Way, Suite 100; Mississauga, Ontario, Canada L4W 5N6.

Safe and satisfactory operation of a connectors for outdoor gas appliances and manufactured homes depends to a great extent upon its proper installation. It should be installed, as applicable, in accordance with the National Fuel Cas Code, ANSI Z223.1/NFPA 54; the Natural Gas and Propane Installation Code, CSA B149.1; the (US.) Manufactured Home Construction and Safety Standard, Title 24 CFR, Part 3280, or when such standard is not applicable, the Standard for Manufactured Home Installations, Sites and Communities, ANSI/NFPA 501A, or the Standard for Mobile Homes, CAN/CSA-Z240 MH Series; or the manufacturers' installation instructions and local municipal codes.

Users of this American National Standard/CSA Standard are advised that the devices, products and activities within its scope may be subject to regulation at the Federal, Territorial, Provincial, state or local level. Users are strongly urged to investigate this possibility through appropriate channels. In the event of a conflict with this standard, the Federal, Territorial, Provincial, state or local regulation should be followed.

THIS STANDARD IS INTENDED TO BE USED BY THE MANUFACTURING SECTOR AND BY THOSE APPLYING THE EQUIPMENT AND BY THOSE RESPONSIBLE FOR ITS PROPER INSTALLATION. IT IS THE RESPONSIBILITY OF THESE USERS TO DETERMINE THAT IN EACH CASE THIS STANDARD IS SUITABLE FOR AND APPLICABLE TO THE SPECIFIC USE THEY INTEND.
