3. MOUNTING THE HEATER
IMPORTANT!
Ensure that the mounting surface / ceiling supports are capable of
taking the additional weight of the heater.
IMPORTANT!
Before cutting out the hole to take the heater ensure there is
200mm clearance behind and that there are no cables or pipes in the way.
The heater is intended for installation in ceilings, walls or bulkheads. When wall
mounted the heater MUST be positioned horizontally. For optimum results do not fit in
ceilings lower than 1.8m or higher than 3m. As air is only introduced through the front of
the unit the heater may be sited anywhere. The air intake and discharge areas must be
kept completely clear for a minimum of 1.5m from the front of the heater. In an area
using multiple units, heaters should be spread to provide an even heat distribution.
Cut a rectangular hole 560mm long x 150mm wide (See drawing to the right).
The heater should be held in position using suitable fixtures using the pre-punched
slots / holes in the face of the unit.
