Gas-fired domestic illuminating appliances
1 Scope 1.1 Applicable equipment This Standard applies to newly produced illuminating appliances constructed entirely of new and unused parts and materials for use with a) natural gas; b) liquefied petroleum gases; c) butane gas; and d) liquefied petroleum (LP) gas-air mixtures. The construction of illuminating appliances for use with these gases is covered in Clause 4. The performance of illuminating appliances for use with these gases is covered in Clause 5. 1.2 Applicable equipment for fixed gas piping systems This Standard covers gas-fired illuminating appliances for either outdoor or indoor installation, or both, and designed to be attached to fixed gas piping systems. 1.3 Non-applicable equipment This Standard is not intended to cover open flame-illuminating appliances with an input rating greater than 5000 BTU/h (1465 W) per burner. 1.4 Pressure references Throughout this Standard, gauge pressures are designated in pounds per square inch (psi) and kilopascals (kPa). The terminology “psig” is not used. Where “psi” is used, it is understood to be pound per square inch gauge. Absolute pressures are not used in this Standard. 1.5 Measurement units The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. 1.6 Mandatory language In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
