3.6 Reducing Clearances
The clearances to combustible specified in section 2.0 of this manual, can be safely reduced by following
guidelines specified in AS/NZS 2918:2001 table 3.1 & 3.2.
-
Heat shield should be made of non-combustible material like metal or masonry.
-
Installed between burner and the combustible wall
-
With an air gap behind it and vented top and bottom
-
The shield should extend a minimum of 450mm beyond the top of the appliance and extend width-wise so
that unshielded rear clearance is maintained
