This video from the 2022 NCC Seminars discusses Part H7 Ancillary Provisions from NCC 2022 Volume Two.
My name is Phil Finnimore from the Australian Building Codes Board, I'm going to talk to
you about some changes that have been made to Part H7 ancillary provisions in NCC 2022.
These provisions relate to heating appliances, the main change that's happened is the removal of any
reference to boilers and pressure vessels, you won't find those in the DtS Provisions for 2022,
compared to those provisions currently existing in 2019. Part 12.4 heating appliances the main
change that's happened in this particular clause has been clarification about the use of AS/NZS 2918.
If you have a look there in 12.4.5 the installation of freestanding heating appliances
must comply with either AS/NZS 2918 for safety clearances or be located in
accordance with those requirements in subclause (a)(ii) or (iii). The difference in (d) sets out that any
flue needs to be tested in accordance with AS/NZS 2019, there are no other Deemed-to-Satisfy
choices within the Housing Provisions. So in summary the installation of the heating
appliance you have a choice between installing it to AS 2918 or the provisions in 12.4.5(a)(ii) and (iii)
but for the flues you must comply with AS/NZS 2918 both for testing and safety clearances.
