CSA/AM - ANSI Z21.20
Automatic Gas Ignition Systems and Components
|Publication Date:||1 January 2000|
This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of an automatic gas ignition system and components. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on automatic gas ignition system 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 thing 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 automatic 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 bad, Cleveland, Ohio 44131.
Safe and satisfactory operation of an automatic gas ignition system 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 2223.1, manufacturers' installation instruction and local municipal codes.
