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 clearance + 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.
