INSTALLATION REQUIREMENTS (continued)
Avoid locating the terminal in close proximity to combustible materials, such as plastic drainpipes
and fences. If these are impossible to avoid, then a suitable metal deflector must be used if the
flue gasses begin to heat the object. For minimum standard dimensions of clearance see below.
Covered areas such as under car ports should be avoided but if no alternative is available the fol-
lowing notes should be adhered to; The covered area should have at least two open sides (i.e. a
roof and ONE supporting wall). If more than one side is filled, then advice must be sought on the
location’s suitability. Any openings into dwellings such as doors, windows and air vents under the
covered area must be at least 1200mm away from the terminal position. If the roof is construct-
ed from plastic material, great care must be taken with the installation as there is no simple
method of protecting this type of roof from heat build up.
TERMINAL LOCATION
Minimum location distances
A - 300mm above ground level/roof or balcony level.
B - 200mm below balconies or car ports.
C - 1500mm vertically between terminals.
D - 300mm horizontally between terminals on same wall.
E - 75mm below gutters, soil pipes or drain pipes.
F - 200mm below eaves.
G - 300mm from internal or external corners
H - 150mm from vertical drain pipes.
J - 300mm directly below an openable window or other
opening e.g. air vent .
K - 1200mm from an opening into the building under a car port.
L - 600mm from a surface facing the terminal.
M - 1200mm from another terminal facing the terminal.
Care should also be taken with the terminal location relative to nearby plants, grass, or trees as
the gases expelled may be hot enough to damage them. At least 1000mm clearance is recom-
mended.
Note: Dimensions relate specifically to the exhaust outlet at the base of fan terminal box.
