POSITIONING THE HEATER
Select a dry site on any rigid flooring surface, keeping in mind the following:-
• A central position free of strong draughts will ensure even heat dispersal.
• Check that the flue (if any) and its shielding will be able to pass through the
ceiling space and roof without interfering with any structural timberwork.
• The flue (if any) must terminate above the roof, no less than 500mm clear of
any part of the roof, and at least 1 metre horizontally from any
neighbouring structure.
• The minimum specified clearance distances to heat sensitive materials
MUST be maintained at all times, and sufficient room will be needed to
facilitate servicing the heater.
❇Note: Clearances are for fire hazard only. For durability of finishes or
surfaces you should contact the relevant manufacturer for their
specification. MASPORT accepts no responsibility for the deterioration of
surfaces or finishes.
• Avoid positions where curtains or furniture might accidentally come too
close to the heater.
• Select a location where the gas supply can be installed readily. If a
circulating fan is to be fitted, an electrical outlet will also be required.

MINIMUM INSTALLATION CLEARANCES (To heat sensitive surfaces) ❇
FLUED APPLIANCES
NO FLOOR PROTECTOR (HEARTH) IS REQUIRED
Alcove installation not permitted.
INSTALLATION
SHIMS
The glass panels are protected from shipping damage by paper shims fitted between the
front and side glasses. Before lighting the heater, remove the shims.
GAS
Access to the gas connection point is obtained by removing the cover panel on the rear of
the cabinet. (Four screws)
Connection is made to the Boston LP model using a 3/8” BSP fitting. The other models
use a 1/2” BSP fitting. 3

The Calgary (flueless) models use a flexible hose and bayonet. The bayonet can be
connected to an AGA approved G 1/2” floor bayonet socket.
In all cases a shut-off valve should be installed directly behind the heater to facilitate
isolation of the heater for servicing.
It is essential to purge all gas lines before making the connection to the heater to
eliminate any swarf. Do not make the connection until the suitability of the flue position
has been confirmed.
GAS PRESSURE ADJUSTMENT. All pressure adjustments must be made while the
heater is operating on the ‘HIGH’ setting.
BOSTON NG. This has a pressure regulator separate from its control valve. The
regulator must be set to 1.0 kPa. The pressure test point is on the side of the
regulator and the adjusting screw is on the top. Slacken the lock-nut and rotate the
screw by hand, screwing down to increase the pressure. Tighten the lock nut after
adjusting.
BOSTON LP. This model has no internal pressure regulator as it runs directly on the
2.71 kPa pressure delivered by the gas bottle regulator.
CALGARY NG . These have a pressure regulator built into the control valve. The
pressure test point is the top one on the end of the control valve furthest from the gas
inlet. Pressure adjustments are made with the small slotted screw above and slightly
to the right of the gas inlet on the control valve. Adjust to 0.9 kPa.
CALGARY LP. There is no pressure regulator in the control valve. The correct pressure
of 2.71 kPa should be delivered by the gas bottle regulator. The test point for
checking this pressure is the uppermost one on the end of the appliance valve
furthest from the gas inlet.
ELECTRICITY. Plug the fan lead into a 230 volt power outlet and check that the fan
operates correctly on all speeds. The fan switch is under the lid (on the cabinet top)
which covers the gas controls.
FLUE (For Boston models)
USE ONLY AN APPROVED FLUE SYSTEM.
1. Stand the heater in its proposed position, taking care to observe the minimum
clearances shown on page 3. The heater does not require a hearth or floor
protector.
2. Drop a plumb-bob from the ceiling to hang centrally in the flue socket of the
heater and mark the position on the ceiling. Drive a small nail through at this
point and inspect the ceiling and roof to ensure that the flue and its trim will be
at least 25mm clear of any combustible material. The flue termination
requirements stated in ‘Positioning the Heater’ (page 2) will also need to be met.
3. Cut appropriate holes through the ceiling and roof material and install the flue
in accordance with the instructions accompanying it, taking care to provide any
safety clearances specified in the instructions (usually 25mm between the flue
shield and any nearby combustible material). The installation must meet the
requirements of AG 601 or NZS 5261 as appropriate. The top of the flue must be
above the roof, at least 500mm clear of any part of the roof and at least 1 metre
horizontally from any neighbouring structure. All flue sections must be securely
coupled to each other.
5. Flash the upper flue at the point of exit through the roof, to prevent water entry,
and fit the flue cap.
It is the responsibility of the installer to ensure that the flue system is
operating correctly. See ‘TEST FIRING’ below.
4

SEISMIC RESTRAINT
New Zealand regulations require that flued gas heaters be secured to prevent shifting in
the event of an earthquake. This is best done by fastening the heater to the floor right
through any floor protector that may be fitted. Fasten with two screws not less than 12
gauge or the equivalent in coach screws or toggle fasteners. Anchor the appliance
through the holes in the seismic restraint bracket or in the two angle brackets supplied.
The angle brackets attach at each side of the pedestal. If the seismic restraint bracket is
used instead, it can be fastened to the rear of the pedestal either before or after fitting
the anchor screws. The small centreline hole in the bracket will help in pre-positioning
it.

TEST FIRING
It is absolutely essential that the installer test fires the heater before leaving the site.
If fitted, open the gas supply valve at the rear of the heater and check all gas joints for
leakage using a leak check solution or an electronic ‘sniffer’, NOT a naked flame.
Carry out the following test firing procedure.
LIGHT THE PILOT:-
NOTE: The pilot can be seen through the hole in the right hand end of the front log.
Boston models:-
• Press down on the control knob at the top of the heater and turn it slowly
anticlockwise. The piezo igniter will click as a spark jumps across the
terminals at the pilot light. It may be necessary to repeat this several times
before the pilot ignites if there is air in the pilot light pipeline.
Calgary models:-
• Turn the control knob anti-clockwise to the ‘PILOT’ position. Hold the control
knob down while pressing the red button of the battery igniter (alongside the
control knob). A continuous spark should appear at the pilot light. It may be
necessary to hold the red button down for some time if there is air in the pilot
light pipeline. Note that the Calgary valve incorporates a safety feature
which prevents re-lighting the fire within two minutes of shutting it down.
ONCE THE PILOT IS ALIGHT:-
Boston models :-
• Keep holding the control knob down for 15 seconds after ignition. Release the
pressure on the control knob – the pilot should remain alight when the knob
rises. 5

• Turn the control fully anticlockwise to the ‘HIGH’ position and the fire will
light at full heat. There may be a strong smell the first time the logs are fired
but this will soon disappear.
• After ten minutes, set the control to give the desired heat output.
• Hold a smoking taper at the exit of the draught diverter (behind the heater)
to verify that the flue is drawing correctly and that flue gases are not spilling
into the room.
• Turn on the fan and check its operation at all three speeds.
Calgary models:-
• Release the pressure on the red igniter button but keep holding the control
knob down for 15 seconds after ignition. Release the pressure on the control
knob – the pilot should remain alight when the knob rises. On Calgary
models the control knob is a thermostat control.
• Turn the control to the desired room temperature setting (1 to 6). If the room
is not already warmer than this setting, the fire will light.
• Check that the fire gradually closes down and then shuts off as the room
warms up to the set temperature. Confirm that the fire re-lights if the
temperature set point is raised above the room temperature.
• Turn on the fan and check its operation at all three speeds.
All models:-
After the fire has been alight for five minutes on ‘HIGH’, hold a smoking taper
or match at the exit of the draught hood (behind the heater) to verify that the
flue is drawing correctly and that flue gases are not spilling into the room.
Drawn in: No spillage Blown out: Spillage/Backdraughting
TURN THE FIRE OFF:-
All models:-
• Turn the control to the ‘PILOT’ position. The pilot will remain alight.
• If the fan is running, turn it off either at the rotary switch or the wall socket.
• To extinguish the pilot light on the Boston models, press down on the control
and turn it fully clockwise to the ‘OFF’ position. To extinguish the pilot light
on Calgary models, turn the control knob fully clockwise firmly past the
‘click’.
• Repeat the above lighting procedure to confirm rapid pilot ignition and
satisfactory burner control.
In the event that satisfactory operation cannot be achieved, contact the
Supplier for further advice.

SERVICING INSTRUCTIONS
Servicing must be carried out only by authorised personnel.
Minor adjustments can be made with the heater in its normal operating position,
but it will be found more convenient to move the heater away from the wall for
major work.
If it is necessary to move the heater:-
• Shut off the gas supply at the valve behind the heater.
• Remove the access plate on the rear of the cabinet.
• Disconnect the gas line at the heater.
Boston (flued) models only
• Lift the flue trim about 75mm and support it with a wooden block.
• Slacken any flue clamp, and lift the flue while moving the heater from beneath
it.
• Slide the heater away from the wall, supporting the flue and trim on a suitable
spacer.
All models
• Keep the heater upright at all times to avoid displacing the logs. The correct
gas-log positions are shown below.
ACCESS POINTS
1. The cabinet rear and side cover plates. These give access to the gas entry
connection, the pressure regulator and the gas control valve (incorporating the
piezo igniter module). On the Boston models the filter for the pilot light gas supply
is under the large cheese-headed screw on top of the gas control valve.
2. The fan assembly. Removal gives access to the main burner gas connection and
injector. The correct injector size for each gas is specified on the data plate on a
chain at the rear of the cabinet. The main burner aeration is not adjustable.
3. The glass. See below for removal instructions. Access is then available for the log
assembly, the pilot light, igniter points and flame safety sensor and the main
burner.
4. The entire upper cabinet may be removed if access to the heat exchanger is
necessary. First remove the glass. The cabinet is retained by eight screws from
underneath and three screws on each front vertical edge of the firebox.
GLASS REMOVAL AND ASSEMBLY
Carry out these procedures only while the heater is standing upright.
1. Remove the louvre by lifting it upwards and outwards.
2. Remove six fastening screws securing the top glass trim.
7

3. Lift the top glass trim clear. Note. This will release the top edges of the three glass
pieces. Ensure that they do not drop out.
4. Lift the front glass clear.
5. Lift each side glass clear. They will reveal at their rear edges a glass sealing rope, a
backing strip and a spring.
Fastening Screw
Spring
Glass Rope
Side Glass
Backing Strip
6. Assembly is the reverse of the above. Clean the inside surfaces of the glass and
keep fingerprints off them as they are assembled. First assemble one side glass to
the heater. Fit the spring first, then the backing strip, then the rope and finally the
glass.
7. With one side glass in place, the front glass can be fitted. Press the side glass back
to compress its spring so that the front glass can drop into its slot.
8. Hold the two top front corners of the glasses together with a piece of sticky tape to
stop them falling outwards.
9. Fit the second side glass as in 6 above. Once it is pressed back into the rear slot it
can swing in behind the front glass and then drop down into its bottom slot.
10. Replace the top glass trim, fit its fastening screws, remove the sticky tape and refit
the louvre.
PILOT FLAME ADJUSTMENT (Calgary (flueless) models are not adjustable)
If the pilot flame aeration needs adjustment, it can be done by rotating the air entry
adjusting sleeve located about half way up the barrel of the pilot burner, using the end
of a long small screwdriver. Access is gained by removing the glass and lifting the front
log clear (see above).
MAIN BURNER REMOVAL
1. Remove the glass (see above).
2. Lift the logs out carefully.
3. Remove the pedestal rear cover plate (or fan, if fitted).
4. Disconnect the feed pipe at the main injector (brass elbow).
5. Unscrew the main injector.
8

6. Inside the firebox, remove the air metering plate (just in front of the burner – three
screws) and lift out the draught deflector. Remove the four burner retaining screws.
7. Ease the burner up a little and remove the entire pilot light/igniter assembly (two
nuts) from the main burner.
8. Lift the burner clear of the firebox.
ROUTINE MAINTENANCE SCHEDULE
We recommend that you have your Masport heater checked yearly by an
Authorised Technician.
This periodic maintenance should cover the following points:-
1. Replace the filter in the control valve (Boston models only).
2. Replace the battery in the igniter module (Calgary only). Access the battery by
unscrewing the black top cap surrounding the red ignition press button. One AA
alkaline cell required.
2. Clean all air entry points such as primary and secondary air inlet passages.
3. Clean the main injector jet hole(s).
4. Clean the fan of any lint or foreign matter.
5. After the above steps, check the operation of the pilot, the main burner and the
control valve by lighting the fire.
6. Check the operation of the thermostat (Calgary models) by turning its control point
above and below the ambient room temperature and checking the response of the
fire.
Other points which can be checked after completing the above are:-
1. Thermocouple generation.
2. Gas consumption rate.
3. Carbon dioxide content in the combustion products.
4. The flue operation. (Boston models only).
Note: To ensure satisfactory performance, all components fitted should
be genuine Masport spare parts.

TROUBLE - SHOOTING
The following table lists possible problems and their likely causes. Most of these will
require a professional serviceman and we recommend that this work be performed by an
Authorised Technician. If a problem cannot be solved after referring to this table, please
call your Masport gas fire Dealer for help.
PROBLEM POSSIBLE CAUSE(S) SOLUTION
Pilot will not light and
there is no strong blue
spark.
Faulty battery in igniter
(Calgary only). Fit a new AA alkaline cell in igniter. (See routine
Maintenance).
Faulty electrode wire or
wire connection(s). Make sure wire is not shorting and connections are
firm at each end.
Pilot will not light even
though there is a strong
blue spark.
Incorrect lighting procedure. Follow the instructions in
this manual.
No gas supply at heater. Check for closed gas valve(s)
or faulty gas supply lines.
Pilot filter or jet blocked. Replace the filter in control
valve (Boston only). Clean
jet (Both models).
No fuel in LPG system. Replenish LPG supply.
Pilot stays alight but
main burner will not
light.
Thermostat, (Calgary
models), is switched to OFF
or set to a low temperature.
Check thermostat setting.
Switch to ON or turn to a
higher temperature.
Smell of flue gas in the
room. Flue gas spilling from the draught diverter at the rear
of the heater (Boston only).
Check for flue blockage,
negative air pressure in the
room or circumstances
causing down-draught.
Smell of gas in the room. Pipe fittings may be
leaking. Check all joints for leaks, including the gas supply
system, the pilot light
supply tube, the main
burner supply tube and all
connections to the control
valve and pressure reducing
valve (NG models). Use
ONLY a proper leak check
solution. NEVER USE AN
OPEN FLAME TO CHECK
FOR LEAKS.

10

PROBLEM POSSIBLE CAUSE(S) SOLUTION
A thin coating of black
soot forms inside the
glass.
Combustion air supply
restricted. Clean all primary and secondary air passageways.
Over-supply of gas. Adjust gas delivery pressure
at test point.
Logs out of position. Arrange logs correctly.
A white coating forms
inside the glass. Residues of new logs being burned off. Follow glass cleaning directions under Cleaning
Instructions.
Fan hums bit there is
poor air circulation. Dirty fan impeller. Disconnect electrical power. Remove fan and clean
impeller.
Fan will not run. No power to fan. Make sure the fan plug is
firmly home and that fan
switch is not in the OFF
position. Check that the
power socket works with
another appliance.
Flueless heater (Calgary)
shuts down repeatedly. Oxygen in room air depleted. Provide fresh air ventilation into room.
CLEANING INSTRUCTIONS
The outside of the cabinet and glass should need no more than an occasional wipe with
a damp cloth to remove any dust which may have settled.
All visible flame gas heaters can produce small amounts of soot, particularly if the
combustion air entry slots under the heater are obstructed or the aeration air inlets are
clogged with lint.
After a long period the inside of the glass may require cleaning. To do this, carefully
remove the three glass pieces (See Glass Removal and Assembly, page 7), and clean
their inside surfaces with a non-abrasive cloth and a non-scratching type household
cleaning liquid. Replace the parts as detailed on page 8, keeping fingerprints off the
inside glass surfaces.
No other user maintenance should be necessary. If you require any other service or
adjustments, contact your Installer or Dealer.

OPERATING INSTRUCTIONS
DO NOT PLACE ARTICLES ON OR AGAINST THIS APPLIANCE.
DO NOT USE OR STORE FLAMMABLE MATERIALS NEAR THIS APPLIANCE.
DO NOT SPRAY AEROSOLS IN THE VICINITY OF THIS APPLIANCE WHILE IT IS
IN OPERATION.
TO LIGHT THE PILOT:-
• If necessary, open the gas supply valve (if fitted) behind the appliance. The pilot can
be observed through the hole in the right hand end of the front log.
Boston models:-
• Press down on the control knob at the top of the heater and turn it slowly
anticlockwise. The piezo igniter will click as a spark jumps across the terminals at
the pilot light. It may be necessary to repeat this several times before the pilot
ignites if there is air in the pilot light pipeline.
Calgary models:-
• Turn the control knob anti-clockwise to the ‘PILOT’ position. Hold the control knob
down while pressing the red button of the battery igniter (alongside the control
knob). A continuous spark should appear at the pilot light. It may be necessary to
hold the red button down for some time if there is air in the pilot light pipeline. If
no spark can be seen (or heard), unscrew the black top cap surrounding the red
ignition press button and check the battery, replacing if necessary with one AA
alkaline cell. Note that the Calgary valve incorporates a safety feature which
prevents re-lighting the fire within two minutes of shutting it down.
ONCE THE PILOT IS ALIGHT:-
Boston models :-
• Keep holding the control knob down for 15 seconds after ignition. Release the
pressure on the control knob – the pilot should remain alight when the knob rises.
• Turn the control fully anticlockwise to the ‘HIGH’ position and the fire will light at
full heat. There may be a strong smell the first time the logs are fired but this will
soon disappear.
• After ten minutes, set the control to give the desired heat output.
• After the fire has been alight for ten minutes you may turn on the fan by rotating
the fan switch in either direction. The switch gives three speeds and has an ‘off’
position.
Calgary models:-
• Keep holding the control knob down for 15 seconds after ignition. Release the
pressure on the control knob – the pilot should remain alight when the knob rises.
On Calgary models the control knob is a thermostat control.
• Turn the control to the desired room temperature setting (1 to 6). If the room is not
already warmer than this setting, the fire will light.
• As the room warms up toward the set temperature, the fire will gradually close
down and eventually shut off completely when the room has reached the selected
temperature.
• After the fire has been alight for ten minutes, you may turn on the fan by rotating
the fan switch in either direction. The switch gives three speeds and has an ‘off’
position.
• When the room temperature falls below the set point, the fire will automatically re-
light. Unless the room is well below the set point, the fire will not come onto full
heat. 12

• If a different room temperature is desired, turn the control knob to a higher number
for increased heat, or to a lower number for a lower room temperature.
• Once the comfortable room temperature has been established, it is usually not
necessary to run the heater at any other control knob setting.
TO TURN THE FIRE OFF:-
All models:-
• Turn the control to the ‘PILOT’ position. The pilot will remain alight.
• If the fan is running, turn it off either at the rotary switch or the wall socket.
• To extinguish the pilot light on the Boston models, press down on the control and
turn it fully clockwise to the ‘OFF’ position. To extinguish the pilot light on
Calgary models, turn the control knob fully clockwise firmly past the ‘click’.
