TEST FOR FLUE
SPILLAGE
A " spillage" test must be made before
the installed unit is left with the custom-
er. Follow the procedure below:
1) Start all exhaust fans in the home and then
close all external doors and windows in the
house.
2) Light the unit and set controls to maximum.
Turn fan off.
3) After five minutes, test that there is a “pull”
on the flue by placing a smoke match,
cigarette or similar device which gives off
smoke, in front of the spill tube. To ensure
a valid test, place a scrap piece of sheet
metal (or other noncombustible material)
betweenthespilltubeandtheupperlouvre,
this will prevent the natural convection of
the unit from interfering with the test. See
diagram 1.

AERATION SYSTEM
The aeration adjustment rod is attached to the
air shutter which is located just above the
orifice bracket. The rod is used to adjust the
aeration on the main burner without having to
take the appliance apart.
Theburner aeration is factorysetbut may need
adjusting due to either the local gas supply, air
supplyoraltitude.Thisadjustmentisperformed
by the installer. (Pull the rod for a more yellow
flame,or push therod to makethe flame bluer.)
Natural Gas: 8 mm open
Propane: full open
Note: Any damage due to carboning re-
sulting from improperly setting
the aeration controls is NOT cov-
ered under warranty.
INSTALLATION
DRAFT DIVERTER
CONNECTION
1) Attach the flue to the flue collar on the
detachable draft diverter. The flue collar of
the appliance will fit inside a standard flue
and may be fastened directly to the flue by
sheet metal screw. Diagram 1.
NOTE: Final gas connection should be af-
ter unit is in place to avoid damage
to line when pushing the unit into

diameter twin skin or listed gas fuel type flue
liner running the full length of the chimney. A
minimumflueheightof3.6m. is recommended.
The Masport Inbuilt Fireplace incorporates its
own internal draft diverter, so no additional
external draftdiverter is required.
Periodically check that the flue is unrestricted
and an adequate draft is present when the unit
is in operation. (See page 7 for spillage test.)
Before installing flue system ensure that the
damper plate is open and secure to prevent the
damper plate from falling down and crushing
the liner.
Install to AG 601,(Australia) NZS 5261 (New
Zealand).
Combustion and Ventilation Air
WARNING: This appliance needs
freshairforsafeoperationandmust
beinstalledwithprovisionsforade-
quate combustion and ventilation
air available to the room in which it
is to be operating.
Air for combustion is drawn in through the front
of the unit, therefore, the front of the unit must
be kept clear of any obstructions.
GAS PRESSURE TEST
The unit is preset to give the correct gas input
at the specified manifold pressures shown on
the label. The maximum gas manifold pressure
is: Natural Gas 0.95kPa
Propane 2.65kPa
The manifold pressure is controlled by a regu-
lator built into the gas control, and should be
checked at the pressure test point. The pres-
sure check should be carried out with the unit
burning and the setting should be within the
limits specified.
2) Before pushing the appliance into position
inside the fireplace, align the draft diverter
with the guides on the insert top and push
forward. While pushing the unit back into
place keep pulling the draft diverter forward
until the screw hole in the spill tube aligns
with the screw hole in the top of the firebox.
Thescrew is secured through theinside top
ofthefireboxintothebottomofthespilltube.
(If screw holes do not line up then draft
diverter is not positioned correctly.)

INSTALLATION
The smoke should be drawn into the spill tube.
If the smoke is still not drawn into the spill tube,
turn the unit off and check for the cause of the
lack of draft. If necessary, rectify.
Diagram 1
Diagram 2
Diagram 3
For wind turbulent sites, a wind cap may rem-
edy the problem.
Note: The thermally activated safety
switch will sense the change in temper-
ature and shut down the gas valve in the
event of a severe downdraft or a blocked
or disconnected flue. The switch acts as
a safety shut-off to prevent a build-up of
carbon monoxide. If the flue is blocked or
has no "draw", the switch will automati-
cally shut off the supply of gas within 5 -
10 minutes. Tampering with the switch
can result in carbon monoxide (CO) poi-
soning and possible death.
If the heater turns off because of lack of
draft during the spillage test, check for
the cause and if necessary, rectify.
The thermally actuated safety switch will
automatically reset after it has cooled off.
The switch will continue to cycle until the
draft problem is corrected. DO NOT BY-
PASSOR DISCONNECT THISSWITCH.

FIRST FIRE
The first fire in your stove is part of the paint
curing process. To ensure that the paint is
properlycured,itisrecommendedthat you burn
your fireplace for at least four (4) hours the first
time you use it with the fan on. When first
operated, the unit will release an odour caused
by the curing of the paint, the burning off of any
oils remaining from manufacturing. Smoke de-
tectorsinthehousemaygooffatthistime.Open
a few windows to ventilate the room for a
couple of hours.
The glass panel may require cleaning after the
unit has cooled down.
DO NOT ATTEMPT TO CLEAN THE GLASS
WHILE IT IS HOT.
Note: When the glass is cold and the
appliance is lit, it may cause con-
densation and fog the glass. This
condensation is normal and will
disappear in a few minutes as the
glass heats up.
DO NOT BURN THE APPLIANCE
WITHOUT THE GLASS FRONT IN
PLACE.
AUTOMATIC
CONVECTION
FAN OPERATION
The fan operates automatically, press the
High/Low Fan switch on the side of the face-
platetoadjust to the desired speed.Thefanwill
turn on as the stove comes up to operating
temperature. After the unit has been turned off
andtheunitcooledtobelowausefulheatoutput
range the fan will shut off automatically.
NORMAL OPERATING
SOUNDS OF
GAS APPLIANCES
It is possible that you will hear some sounds
from your gas appliance. This is perfectly
normal due to the fact that there are various
gauges and types of steel used within your
appliance.Listedbelowaresomeexamples.All
are normal operating sounds and should
notbe considered as defectsin your appliance.
Blower:
Masport gas appliances use high tech blowers
to push heated air farther into the room. It is not
unusual for the fan to make a "whirring" sound
whenON. This soundwill increase ordecrease
in volume depending on the speed setting of
your fan speed control.
Burner Tray:
The burner tray is positioned directly under the
burner tube(s) and logs and is made of a
different gauge material from the rest of the
firebox and body. Therefore, the varying thick-
nesses of steel will expand and contract at
slightly different rates which can cause "tick-
ing"and"cracking" sounds. You should alsobe
aware that as there are temperature changes
within the unit these sounds will likely re-occur.
Again, this is normal for steel fireboxes.
Blower Thermodisc:
When this thermally activated switch turns ON
itwill create a small"clicking"sound. This isthe
switch contacts closing and is normal.
