ANSI Z21.77-2005 (R2020)/CSA 6.23-2005 (R2020)

Scope 1.1.1 This standard applies to newly produced manually-operated piezo-electric spark gas ignition systems (see Part IV, Definitions), hereinafter referred to as piezo ignition systems, and components constructed entirely of new, unused parts and materials, which are intended to form an integral part of a gas appliance. A piezo ignition system shall perform the following functions: a. Generate piezo-electric energy (spark generator); b. Transmit the energy (high voltage leads); and c. Utilize the energy to produce arcs (spark electrode). Components submitted for examination under this standard shall perform one or more of the above functions; however, a component performing only b is not covered under the scope of this standard. 1.1.2 This standard applies to piezo ignition systems and components for use with one or more of the following gases: a. Natural; b. Manufactured; c. Mixed; d. Liquefied Petroleum; and e. LP gas-air mixtures. 1.1.3 Compliance of a piezo 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 a piezo ignition system shall be capable of operation throughout a temperature range of 32°F to 125°F (0°C to 51.5°C). A higher, lower, or both higher and lower temperature may be specified by the manufacturer. 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 All references to psi throughout this standard are to be considered gage pressures unless otherwise specified. 1.1.7 Exhibit A contains provisions that are unique to Canada. 1.1.8 Exhibit B contains provisions that are unique to the United States. 1.1.9 Exhibit C contains a list of standards specifically referenced in this standard, and sources from which these reference standards may be obtained.
