PREFACE

This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of a combination gas control for gas appliances. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on combination gas controls for gas appliances designed for utilization of gas. There are risks of injury to persons inherent in appliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in this standard are intended to help 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 combination gas controls, the safety 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 or suggestions should be forwarded to the Chairman of Accredited Standards Committee Z83, 8501 East Pleasant Valley Road, Cleveland, Ohio 44131, or the Chairman of the Canadian Gas Association Standards Steering Committee on Gas Burning Appliances and Related Accessories, 55 Scared ale Road, Don Mills, Ontario, Canada, M36 2R3.

Safe and satisfactory operation of a combination gas control for gas appliances depends to a great extent upon its proper installation, use and maintenance. It should be installed, as applicable, in accordance with the National Fuel Gas Code, ANSI Z223.1; the Natural Gas Installation Code, CANfCGA-Bl49.1; the Propane Installation Code, CAN/CGAB149.2.

Users of this American National Standard/Canadian Gas Association 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.

NOTICE TO READER: The Canadian Gas Association (CGA) has been accredited by the Standards Council of Canada to prepare standards in the area of equipment for use with natural gas and propane. Standards are prepared by committees that include representatives from all interests and are so constituted that no one interest may dominate. The interests represented include governmental inspection authorities, certification agencies, manufacturers, utilities, and consumers. Government inspection authorities having jurisdiction review and approve these standards; sitting as the Interprovincial Gas Advisory Council (IGAC).

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.
