HORIZONTAL VENTING
The location of the flue terminal shall comply with the
Australian standard. (See Figure 21):
a) At least 300mm below eaves, balconies and other
projections. * Where eaves have openings into the house or
roof space, the clearance required is 1500 mm.
b) At least 300mm from the ground, above a balcony or other
surface*
c) At least 300mm from a return wall or external corner*.
d) At least 1000m from a gas meter.
e) At least 500mm from an electricity meter or fuse box. The
prohibited area extends below the electricity meter or fuse
to ground level.
f) At least 75mm from a drain pipe or soil pipe.
g) At least 500mm horizontally from any building structure*
or obstruction facing a terminal.
h) At least 300mm from any other flue terminal or combustion air intake.
i) At least 1500mm from an openable window, door, non-mechanical air inlet, or any other opening into a building with
the exception of sub-floor ventilation.
j) At least 1000mm from a mechanical air inlet, including a spa blower.
k) At least 1500mm below an openable window, door, non-mechanical air inlet, or any other opening into a building with
the exception of sub-floor ventilation.
Where the flue terminal is to be installed under a covered area, or in a recess, one of the following options shall be
applied to achieve ready dispersion of combustion products and avoidance of nuisance:
a) The covered area or recess shall be open on at least two sides and the terminal shall be located to ensure a free
flow of air across it is achieved; or
b) When on side is open, the flue terminal shall be within 500 mm of the opening, and discharging in the direction of the
opening (see Figure 22). There shall be no other flue terminals, gas meter, electricity meter, fuse box or openings into
the building along the wall within the 500 mm distance. The flue terminal shall be located to ensure that a free flow of
air across it is achieved.
