HEATER CLEARANCES – OUTDOOR
IMPORTANT!
• In an outdoor installation it is important to ensure water is diverted
from overhanging eves with a proper gutter/drainage system. The heater
must be set on a level foundation for proper drainage.
• This unit shall not be operated outdoors at temperatures below -7
o
C.
The heater shall be located such that the heater’s ue terminal shall
comply with the Australian standard. (See Figure 15, page 21):
a) At least 300 mm below eaves, balconies and other projections
(Figure 14). * Where eaves have openings into the house or roof
space, the clearance required is 1500 mm.
b) At least 150 mm from a return wall.
c) At least 300 mm from an external corner.
d) At least 1000 m from a gas meter.
e) At least 500 mm from an electricity meter or fuse box. The prohibited area extends below the electricity
meter or fuse to ground level.
f) At least 75 mm from a drain pipe or soil pipe.
g) At least 150 mm horizontally from any building structure or obstruction facing a terminal.
h) At least 300 mm from any other ue terminal or combustion air intake.
i) At least 1500 mm from an openable window, door, non-mechanical air inlet, or any other opening into a
building with the exception of sub-oor ventilation.
j) At least 1000 mm from a mechanical air inlet, including a spa blower.
k) At least 1500 mm below an openable window, door, non-mechanical air inlet, or any other opening into a
building with the exception of sub-oor ventilation.
Where the heater 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 ow of air across it is achieved; or
b) When on side is open, the ue terminal shall be within 500 mm of the opening, and discharging in the direction
of the opening. There shall be no other ue terminals, gas meter, electricity meter, fuse box or openings into
the building along the wall within the 500 mm distance. The ue terminal shall be located to ensure that a free
ow of air across it is achieved.
Orient the heater for convenient access to the water connections and the gas and electrical connections.
Check local building codes for setback (property line) requirements.
