ANSI Z21.92-2001 pdf download MANUALLY OPERATED ELECTRIC GAS IGNI7 TION SYSTTEMS AND COMPONENTS
1.1 SCOPE
1.1.1 This standard applies to newly produced manually-operated electric gas ignition systems (see Part 1V, Definitions), hereinafter referred to as ignition systems, and ignition system components constructed entirely of new, unused parts and materials, 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.
a. A spark ignition system shall: 1. Generate high voltage electric energy (spark generator);
2. Transmit the energy (high tension leads); and
3. Utilize the energy to produce arcs (spark electrode). Components of spark ignition systems submitted for examination under this standard shall perform one or more of the above functions; however, a separate high tension lead(s) is not covered under the scope of this standard.
b. A hot surface ignition system shall:
1. Control energy to an igniter; and
2. Utilize the energy to heat an igniter. A component of a hot surface ignition system submitted for examination under this standard shall perform one of the above functions.
1.1.2 This standard applies to ignition systems and components for use with one or more of the following gases: .
a. Natural;
b. Manufactured;
1.1.3 Compliance of an ignition system or component with this standard does not imply that either is acceptable for use on gas appliances without supplemental tests with the device(s) applied to the particular appliance design.
1.1.4 Each component of an ignition system shall be capable of operation throughout a temperature range of32°F to 125°F (0°C to 52°C). The manufacturer is allowed to specify temperatures below 32°F (0°C) and above 125°F (52°C).
1.1.5 If a value for measurement as given in this standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.
1.1.6 Exhibit C contains a list of standards referenced in this standard, and sources from which these reference standards may be obtained.
1.2 GENERAL
1.2.1 Construction of an ignition system or component, whether specifically covered by this standard or not, shall be in accordance with reasonable concepts of safety, substantially and duraility. All specifcations as to construction set forth herein may be satisfied by the construction actually prescribed or such other construction as will provide at least equivalent performance.
1.2.2 Construction shall be such that those parts generally recognized as removable for servicing cannot be assembled incorrectly in a manner that will result in a risk of electric shock.
