Specifies requirements for appliance and flue installation for solid fuel burning appliances in dwellings. Sets out alternative means of compliance via performance testing of a prototype installation or the use of prescriptive criteria (dimension, materials, etc) based on a worst case situation.
This Standard specifies requirements for the installation of domestic solid fuel burning appliances which can be fully assembled prior to being transported to the installation site. It does not cover the installation of appliances which must be assembled in situ, or appliances with electrically driven fuel stoker systems.
NOTE: The requirements for the design and construction and the measurements of performance of solid fuel burning appliances in terms of heat output, efficiency and emissions are not covered in this Standard. These topics are dealt with in AS/NZS 3869, AS/NZS 4012 and AS/NZS 4013.
This Standard will be referenced in the Building Code of Australia by way of BCA Amendment No. 10 to be published by 1 January 2002, thereby superseding the previous edition, AS 29181990, which will be withdrawn 12 months from the date of publication of this edition.
This Standard is applicable to the installation of new and tested second-hand domestic solid fuel burning appliances, whether installed in domestic or commercial situations including the following categories:
(a) Space heaters, including open fronted fireplace inserts.
(b) Cooking appliances.
(c) Open-vented water-heating appliances.
(d) Central-heating appliances.
(e) Any combination of two or more of the appliance categories shown in Items (a) to (d) above.
Results of a test on one sample or prototype appliance or accessory shall be applicable to all other appliances or accessories of the same construction.
This Standard is not applicable to:
(i) Warm air distribution ducting systems beyond the primary wall, floor or ceiling penetration.
(ii) Appliances with flue outlets greater than 100 000 mm2.
(iii) The long term durability of materials.
