FRAMING DIMENSIONS
Framework of the installation must conform to local building codes. Non-combustible materials need not be used.
If the appliance is elevated from the ground within the structure, a base must be constructed using suitable material
with supporting joists capable of supporting a minimum of 1.5 times the weight of the appliance.
AS/NZS 5601 "GAS INSTALLATIONS" requires that flue components be supported independently
of the appliance.
CAUTION
For the following framing dimensions it is important to be aware that the studs are offset—the cavity needs to be
framed based on the centreline of the glass, not the opening size.
Base Board and Cut-outs
To ensure everything lines up and fits properly, it is recommended that on the base the following dimensions are
pencilled; glass centreline, unit depth centreline, feet position, gas and room thermistor cut-outs.
Gas supply access
Thermistor / ambient air access Ø 40 mm
* Assumes 10mm plasterboard / All dimensions in mm
A
Thermistor / ambient air access - right glass of centreline
B
Gas supply access - left of glass centreline
C
Support feet centres - left of glass centreline
D
Support feet centres - right glass of centreline
E
Gas supply / thermistor access - from front of enclosure*
CAVITY VENTILATION
Ventilation of at least 2000 mm² is required in the cavity ideally below the base of the heater engine. This is to
provide room air at ambient room temperature to the fire thermistor located in the base of the heater engine.
Ventilation can be via a vent or an open toe kick at the base of the cavity, however it MUST be in the same room
and wall cavity as the heater.
Additionally the top of the cavity needs to be ventilated into the room or another space. This ventilation opening
MUST be at least 2000 mm². This opening is to prevent heat build-up within the cavity, which if left unventilated
could potentially cause damage to wall surfaces or coverings and / or cause the appliance to cut out.
ADDITIONAL FRAMING NOTES
Plaster board is set 1 mm back from the front edge of the frame to allow for a slim edge plaster finish.
To ensure the appliance performs correctly, without rattling, the heater engine MUST be installed on a flat level
support base.
Issues caused by rattling fires not installed on a flat level base, as detailed in this guide, will NOT
be covered by warranty.
