• The support structure must be only non-combustible material. Clearances of the barbeque from
combustible materials (e.g. wooden fences and gyprock walls and painted surfaces): 300mm
from sides and rear; 1000mm vertically above; 10mm below. If part of the structure is composed
of combustible materials, ensure that the combustible material is separated from the sides and
rear of the barbeque by at least 300 mm.
• Adequate clearance around the barbeque must be provided for safe and efficient operation. The
clearances shown in the diagram below ensure that the burners have a supply of fresh air to
operate correctly. Failure to provide enough fresh air to the burners can cause the production of
potentially deadly noxious gases
• At least 72mm clearance is required from the rear of the build-in barbeque support bracket
body to allow the roasting hood to open freely. Refer to the diagram below for details.
• Structure and installation must comply with AS/NZS 5601 including:
(1) Cylinder compartments must have permanent openings ventilating directly to the outside of
the appliance consisting of either:
(a) Perforations uniformly distributed over the height of the enclosure and with a total free area
of not less than 25% of the wall area; or
(b) Separate openings at high and low level such that
(i) The total free area at the high level is not less than 20,000 square mm and is all within
125 mm of the top of the cylinder compartment; and
(ii) The total free area at the low level is not less than 20,000 square mm and
(A) At least 25% of the required total area is within 15mm of the base of the cylinder
compartment; and
(B) The total required area is within 125 mm of the base of the cylinder compartment; and
(C) The openings cannot be obstructed by the gas cylinder.
Note that if a range hood is installed, it must be a minimum of 1200mm above the primary
cooking surface.
(2) Where the cylinder is kept in an enclosed space underneath or near the build-in barbeque,
the following must be observed:
(a) The cylinder must rest on a firm base to ensure that water will not accumulate, and that the
cylinder is clear of the surrounding soil.
(b) There must be a separation panel between the gas cylinder and the barbeque so that if a
high pressure gas leak occurs, there is no direct path between the cylinder compartment and
the bbq firebox.
