INSTALLATION
NOTE THAT GAS CONNECTION AND FLUEING OF THIS INSERT MUST BE MADE BY AN AUTHORISED PERSON,
AND MUST COMPLY WITH THE REQUIREMENTS OF THE GAS ACT AND GAS REGULATIONS, AND THE GAS
APPLIANCE INSTALLATION CODE NZS 5261:2003.
Installation General Points:
The insert must have a 300mm wide non-combustible hearth fitted in front of it. This hearth must extend at least
the full width of the insert and fascia trim.
A gas supply pipe must be run to the left hand rear corner of the insert (looking from the front). This should be
sufficiently large for delivery of up to 70MJ/h of Natural Gas at 2 kPa nom. pressure. 15mm (1/2”) copper is
recommended. We suggest that the connection to the appliance inlet be made with an approved flexible hose
assembly, sufficiently long to allow sliding the insert in and out of the fireplace when installing and servicing. Ensure
the hose is long enough so that the appliance can be removed from the fireplace without putting a strain on the hose.
(Ref 2.6.2.15 of NZS 5261.)
An earthed power outlet socket must be provided adjacent to the appliance to allow connection of the power cord.
A power supply switch must be located external to the wall cavity to enable isolation of the fire when installation
and service work is carried out.
At all times the fireplace is in use, 40,000 sq. mm of effective ventilation shall be provided into the room in which
the fireplace is installed. This is the equivalent of a 750mm wide window opened by 55mm.
Installation into a wall cavity or false chimney:
The insert may be installed into a wall cavity or false chimney. This shall be constructed generally as shown in the
accompanying drawing, of 75 x 50mm nominal sized timber, and gib-board. There must be an air gap of 10mm
at either side of the insert, and 15mm at the top of the insert, between the outside of the steel casing and the timber
framing of the cavity. The timber shall not touch the casing at any point. Two spacers are fitted to the back of the
casing. These ensure the correct amount of room is maintained at the back of the cavity for protection of the gas
hose/regulator and power cord. DO NOT remove these spacers.
The cavity in which the insert is installed must be ventilated to prevent any long term build up of heat. This may be
either vented to the outside of the house or into the room in which the appliance is installed. The area of the vents
should be approximately 250mm x 50mm and there should be one installed near floor level and a second near
ceiling level.
A continuous stainless steel flue pipe must be fitted to the insert and this flue must extend to at least the minimum
height specified in the Gas Appliance Installation Code NZS 5261:2003. The flue must be shielded by an outer
casing extending from the top of the insert casing to the cowl above the roof. The outer casing shall be kept a
minimum of 10mm from combustible surfaces. An approved cowl must be fitted to the top of the flue to prevent entry
of rainwater, debris and birds, etc.
The flange behind the fascia trim must be drilled so that the insert can be fixed into position to prevent movement
in case of earthquake.
