Front wall to heater
The front wall from floor to ceiling shall be non combustible comprising metal
framing (supplied with heater) and cladding material such as
Versalux fibro
cement sheeting. The minimum side clearance from the heater to any timber
framing within the enclosure shall be 165mm (i.e. 165mm cle 35mm
timber frame = 200mm clearance to side wall). Beyond this distance, the front
wall can be any material, eg. Gyprock stud wall.
The supplied steel framing once assembled acts as a surround for the wall heater
to slide into, and as non-combustible internal wall framing for the fibro cement
sheeting to be fastened to. The steel framing is fastened to the top of the steel
cross bearers. Refer to the diagram in the section titled “Suggested Framing”
below for the assembled configuration of the steel framing.
If the ceiling is greater than 2400mm, then additional timber framing can be used
in the front wall so long as it is not less than the clearance of 1170mm above the
top of the heater.
Steel Cross Bearers and Support Channels
Steel bearers are supplied with the heater to support it and provide adequate
ventilation underneath. The weight of the heater is taken on the two 1130mm
long by 100mm high cross bearers and these must be solidly supported with the
rear bearer 25mm clear of the rear wall.
The 500mm long by 100mm high support channels are bolted to the cross
bearers
with the narrow flange to the top and having the top holes at 600 mm
centres (bolts supplied).
Wiring for Fan
Provide a wiring point in the cavity under the heater. If the cavity under the heater
will not be accessible once the heater is installed (such as through a removable
vent) then ensure an extension cord long enough to reach out of the front of the
opening is lying in the base of the cavity.
With the fan and outer trim removed slide the heater into the cavity and fix with
the supplied bolts to the support channels.
Access the power lead and plug the fan lead in to it pushing the lead into the wall
cavity under the heater. Fix the fan in place using the two 6mm screws at either
end.
