Preface
This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of manually operated electric gas ignition systems and components. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on manually operated electric gas ignition systems and components 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 manually operated electric gas ignition systems and components, 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 Z21/83, 8501 East Pleasant Valley Road, Cleveland, Ohio 44131, or the Chairman of the CSA Technical Committee on Gas Appliances and Related Accessories, 178 Rexdale Boulevard, Toronto, Ontario, Canada M9W 1R3.
Safe and satisfactory operation of a manually operated electric gas ignition systems and components 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/NFPA 54; or the Natural Gas and Propane Installation Code, CSA B149.1.
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.
Scope
Details test criteria for manually-operated electric gas ignition systems and ignitions system components which are intended to form an integral part of a gas appliance. An ignition system shall ignite gas at the main or pilot burner using either spark or hot surface ignition. This standard applies to ignition systems and components for use with one or more of the following gases: natural, manufactured, mixed, liquefied petroleum and LP gas-air mixtures.
