This Standard provides specific requirements and test methods for indirect gas-fired ducted air heaters with an energy input not exceeding 500 MJ/h.
For Australia, the fuel gases are natural gas (as described by AS 4564), town gas, liquefied petroleum gas (LP Gas, as described by AS 4670), simulated natural gas (SNG) and tempered liquefied petroleum gas (TLP).
For New Zealand:
(a) The fuel gases are natural gas (as specified in NZS 5442) and general product liquefied petroleum gas (NZLPG) (as specified in NZS 5435).
(b) The thermal efficiency requirements are informative only, except where they relate to safety.
NOTE 1 Appliances falling within the scope of AS 2658 are not covered by this Standard.
NOTE 2 Other statutory or regulatory requirements may be applicable to a product that falls within the scope of this Standard. It is the responsibility of the manufacturer, importer or distributor (as appropriate) to ensure that products conform with such requirements.
