FLUE SYSTEM
THE APPLIANCE MUST NOT BE CONNECTED TO A
CHIMNEY SERVING A SEPARATE SOLID FUEL BURNING
APPLIANCE
This appliance is designed to attach to a 100mm
diameter type B-Vent or approved flexi-liner or listed
gas fuel type flue liner running the full length of the
chimney. A minimum flue height of 3.6m is
recommended and it may be necessary to extend
beyond this. B-Vent flue must be supported by a flue
support - supplied by flue manufacturer. The Masport
Insert incorporates its own internal draft hood, so no
additional external draft hood is required.
Periodically check that the flue is unrestricted and an
adequate draft is present when the unit is in operation.
Install to AG 601, NZS 5261 or local codes.
FIREBOX CASE INSTALLATION
1) Remove the fascia, top and bottom louvres or
grilles. Louvres or grilles swing out at the bottom
and then lift up. The bottom one has a centre
retaining screw, which must be turned 90°
anticlockwise first. (When refitting, simply press
the screw in to secure the louvre or grille).
2) Slide the fireplace into the recess and adjust the
case position so that it is level and its front top
flange is in line with the face of the fireplace
surround. Where seismic restraint is necessary,
screw the bottom of the case to the base of the
fireplace recess. The base of the fireplace must be
levelled (by, for example, grouting) to prevent
vibration from possible fan imbalance.
3) If space above the case for positioning and fixing
the flue is limited, greater access can be provided
by first removing the top louvre or grille ( by lifting
it upwards and outwards).
4) Then remove the two screws holding the top sliding
panel, one is located at each side of the fire. The
top front section of the case can now slide out as
illustrated to increase access.
5) Attach the flue to the flue spigot. The flue spigot of
the appliance will fit inside a standard flue and may
be fastened directly to the flue by sheet metal
screw or a B-Vent, single wall flue connector (not
available from Masport).
6) Once the flue is connected, reassemble the firebox
cabinet by sliding in the top panel.
Note:
The gas connection should be made after
the unit is in place to avoid damage to line
when pushing the heater into position.
COMBUSTION AND VENTILATION AIR
WARNING: This appliance needs fresh air for safe
operation and must be installed with provision for
an adequate supply of combustion and ventilation
air to the room in which it is operating.
Air for combustion is drawn in through the front of the
unit; therefore, this area must be kept clear of any
obstructions.
GAS CONNECTION
GAS CONNECTION WARNING:
Installation must be carried out by a registered installer
who, on completion of the installation, must issue a
certificate of compliance, in accordance with national
and/or local codes. If a certificate of compliance is not
issued then the Masport warranty may be void.
The gas connections are a 3/8” flare for New Zealand
& 1/2" flare for Australia.
When connecting the gas, ensure that the control valve
or pressure regulator is not twisted during this
procedure (such damage is not covered by Masport
warranty).
GAS PIPE TESTING
The appliance must be isolated from the gas
supply piping system by closing its individual
manual shutoff valve (not supplied with heater)
during any pressure testing of the gas supply
piping
system at test
pressures equal to or greater
than 6 kPa.
