1.2. GENERAL OPERATION
Air Controls
The top air slide allows air to enter the firebox from above the
door where it is then drawn down into the base of the fire
while keeping the glass clean. Pull knob out to the left to open
and push in to the right to close.
The bottom air slide allows air to enter directly into the base
of the fire and is used as a boost especially when getting the
fire up to temperature. Slide spring handle to the left to open
and to the right to close. The bottom air slide will reduce
efficiency if left open for extended time and should always be
closed when leaving the room.
Door Handle
Warning: The door handle may get hot if the appliance has
been left in the high burn setting for an extended period. Use
a protective glove to open.
Open the top air slide before opening the door to eliminate
the chance of backdraft and smoke entering the room.
1.3. USING THE APPLIANCE FOR THE FIRST TIME
For the first few times the appliance is lit, odorous fumes
will be given off as the paint cures.
Do not touch the paint work while it is curing otherwise it
can leave a permanent mark on the appliance.
Keep the room well ventilated until these fumes have
cleared.
Once the paint has cured, this will not re-occur.
1.4. RECOMMENDED FUELS
Burn only seasoned hardwood timber with a moisture
content of less than 20%.
Newly cut wood should be split and allowed to
dry/season for 12 to 18 months before use.
Wood should be stored in an environment protected
from the weather to minimise any potential moisture
content.
For best results, wood should not exceed ¾ of the firebox
front to back dimension in length and 150mm in
diameter. Any larger and appliance will not operate at its
optimum. It is better to burn several smaller pieces of
wood than one large piece at a time.
Poor quality timber:
oCauses low combustion efficiency.
oProduces poor emissions (smoky).
oResults in additional build-up of creosote (soot)
in the flue which will then require regular
cleaning and may result in a flue fire.
Do not burn painted, impregnated/treated wood,
manufactured board products or pallet wood.
1.5. LIGHTING THE FIRE
1) Place firelighters or paper and dry kindling wood in the
base of the firebox.
2) Fully open air controls (slide top and bottom air slides to
the left).
3) Light the paper or firelighters.
4) Once the fire has taken hold add larger pieces of wood.
For optimal burn conditions, place the logs in a front to
back orientation (right angles to the door opening). Too
many logs may smother the fire.
5) Once the fire is established, close the bottom air slide
(slide to the right). Leaving this open once the fire has
established can risk over-firing and damaging the
appliance.
Do not leave the appliance unattended while the door is
open.
Do not leave fire unattended with bottom air control open as
over-firing may occur.

1.6. RUNNING THE APPLIANCE
High Heat Output
This setting is not the most energy efficient as some heat is
lost up the flue instead of being transferred into the room.
However, once fire has established, particulate emissions will
be very low (clean burning).
After establishing the fire and loading it with larger pieces
of wood, leave it running with the top air slide fully open
to generate high heat output.
Running the appliance with the door open will not
produce maximum heating in the room as it will draw a
lot of already warmed air out of the room.
Similarly running the heater with the top air slide and the
bottom air slide fully open will often not give the hottest
fire as too much heat is lost up the flue and does not
come into the room
Do not overload firebox with fuel.
Low Heat Output
This setting will provide the best energy efficiency as the
wood burns for longer. However, if not operated correctly
may result in higher particulate emissions.
The heat output on the appliance can be reduced by
closing the air controls which will restrict the oxygen
supplied to the fire and slow down the rate at which the
wood burns.
Prior to closing the air slide, ensure the fire is burning
briskly. This may require opening the air slide fully for 5-
10mins before shutting down.
For the optimum between clean burning, and getting the
best in efficiency, from the fully closed position, open the
top air slide 4-5mm. The bottom air slide must be shut.
The top air slide can be adjusted to any position so
desired depending on wanted heat output versus burn
time.
Reload with more wood
1) Open the top air slide before opening the door.
2) Rake / break up any existing coals.
3) Load wood with the length orientated front to back.
Better results will be achieved by loading several smaller
pieces of wood rather than one large piece.
4) Close the door with the top air slide fully open and leave
for a minimum of 10 minutes to allow the fresh wood to
catch.
5) After 10 or more minutes, the air slide can be adjusted to
the desired heat output setting.
1.7. BURNING TIPS
Fuel Quality
Use wood with a moisture content of less than 20%. Logs
should not feel moist or have moss and fungal growths.
Symptoms of burning wet wood:
Difficulty starting and keeping a fire burning well
Smoke and only small flames
Dirty glass and/or fire bricks
Rapid creosote build-up in the flue/chimney
Low heat output
Short burn times, and blue/grey smoke from the
flue/chimney outlet
If on the rare occasion the wood is not ideally seasoned, still
retaining some moisture, continue using the top air slide to
determine the heat output and burn rate but also leave the
bottom air slide open 3-4mm. This will allow some extra
oxygen into the base of the fire allowing it to burn hotter.
Run appliance at high heat output for a short period each day
to avoid large build-up of tars and creosote within the
appliance and flue.
Flue Draught
The flue has two main functions:
1) To safely remove smoke, gases and fumes from the
appliance.
2) To provide sufficient draught (suction) in the appliance to
ensure the fire keeps burning.
Draught is caused by the rising hot air in the flue when the fire
has been lit.
The position, height and size of the flue can affect the
performance of the flue draught. Refer to installation guide
for details on flue installation.
Factors affecting the flue draught include:
Insufficient flue height
Trees or other buildings nearby causing turbulence
High and gusty winds
Outside temperature and weather conditions
Blocked flue
For advice on the correction of persistent flue problems
consult your supplier/installer for more detail.

1.8. ASH REMOVAL
Depending on the type of wood burnt and frequency, the
ashes will need removing every 2 to 6 weeks.
Leave a 10mm layer of ash to insulate the firebox bottom.
Excess ashes should be removed when necessary, placed in a
non-combustible container with a tightly fitting lid and moved
outdoors immediately to a location clear of combustible
materials.
1.9. FLUE/CHIMNEY FIRE
If a flue/chimney fire occurs:
Shut air controls fully to smother the fire.
Do not use the appliance after a flue fire until an
accredited installer has assessed the cause and any
resultant damage.
1.10. CLEANING PAINT WORK AND GLASS
The appliance, when cool, can be cleaned with a damp
cloth.
Over the years, the black paint will fade and can be
touched up with Stove Bright metallic black paint.
To clean the glass, we recommend using a household
window cleaner or general purpose cleaner with a soft
cloth.
Do not use abrasive cleaner or scourer pads.
1.11. CLEANING THE FLUE
Check inside of flue prior to each season for any build-up of
creosote (wood tar).
To check the flue:
1) Remove the baffle plates (refer to ‘Replacing the Baffle
Plates’ under Maintenance & Servicing).
2) Hold a small mirror on an angle below the flue, with a
torch shining towards it, and look for black creosote
build-up. It is normal to see a fine black powdery layer,
but if built up layers of creosote can be seen, the flue
requires cleaning.
3) If no cleaning is required, re-fit the baffle plate.
To clean the flue:
1) A flue cleaning brush can be purchased from most wood
heater retail outlets or large hardware stores.
Alternatively, hire a flue cleaning service to do the job for
you (it’s a dirty job).
2) With the baffle plates removed, tie a rope to one end of
the brush, and drop the rope down the flue (from outside
on top of the roof).
3) Grab the end of the rope from inside the firebox and pull
the brush down through the flue.
4) Check the inside of the flue with the mirror and torch.
5) Repeat cleaning process if necessary.
6) Once the flue is clean, remove any excess creosote from
the firebox.
7) Replace the baffle plate.
Only pull brush downwards through flue, as pulling upwards
may separate the flue sections at their joins.
1.12. TROUBLESHOOTING TIPS
Glass in door blackening
This can have several possible causes:
Burning unseasoned wood —If the wood is too wet, it
will cause the glass to blacken.
Appliance operated at low temperature —After an
overnight burn where the air control has been fully
closed, the glass may have blackened. When the fire is re-
stoked and burning on the high heat setting, the
blackened glass should self-clean.
Problems with the flue —Insufficient flue draught can
cause the glass to blacken. If the flue is too short, not
properly insulated, or in a position that results in a
downdraught, then there will be insufficient flue draught.
Contact the installer should this happen.
Trouble starting the fire
When cleaning, it is best to retain some ash in the base of the
firebox. A layer of ash insulates the base, helping to maintain
a high temperature for combustion. Also, if all the ash has
been removed from the firebox, it can affect the supply of air
to the base of the fire.

2. MAINTENANCE AND SERVICING
2.1. REPLACING THE FIRE BRICKS
The firebox needs fire bricks to increase the thermal mass and
guarantee the longevity of the steel firebox. Over time the
firebricks may become cracked and crumble away. At this
point they should be replaced.
To replace the firebricks:
1) Raise the brick retainer
2) Remove bricks and ash from the fire box.
3) Replace with new bricks and lower the brick retainer over
the bricks.
Firebrick configuration:
Base of the firebox has 2 outside rows of full bricks
measuring 230 x 115 x 38mm and a centre row which are
shorter in length measuring 175 x 115 x 38mm
Sides of firebox have 8 full bricks standing on their ends.
Back of firebox is lined with 5 full bricks standing on their
ends.
2.2. REPLACING THE BRICK RETAINER
The brick retainer holds the bricks in place. Over time, the
brick retainer may warp or burn through, and should be
replaced.
1) Remove the side and rear fire bricks before fitting the
brick retainer.
2) With the retainer orientated with the arms pointing up
(like a square ‘U’ shape), push one end into the back
corner of the firebox.
3) With the retainer in a diagonal orientation relative to the
firebox, tilt the top slightly forward allowing the bottom
corner to drop into the firebox at the front.
4) Push the bottom front corner towards the back of the
firebox allowing the top of the arm to enter the firebox.
5) Continue pushing the bottom corner towards rear of
firebox so that retainer sits flat in the firebox.
6) Raise the retainer and re-install the fire bricks.
2.3. REPLACING THE BAFFLE PLATES
The baffle plates help to retain the heat in the firebox by
lengthening the path of the flame before it goes up the flue.
Over time, the baffle plates will begin to sag a little due to the
excessive heat. This will not affect the way the fire burns.
Eventually the baffle plates will burn through (5+ years) and
must be replaced.
To remove the baffle plates:
1) Slide the lower baffle plate forward so that it can be
lowered at the back.
2) Lowering the rear of the baffle will allow the front to slide
past the front support pins.
3) Once the baffle has cleared the front support pins, it can
be removed from the firebox.
4) Remove the upper baffle plate in the same way.
5) Slide the front baffle with hooks towards the rear past the
supports.
6) Repeat steps 1) to 4) in reverse to fit the new baffle plates
(see image below for correct baffle placement).

2.4. REPLACING THE ASH PLATE
The ash plate acts to protect the front of the firebox below
the door opening from the hot coal bed and fire.
Over time, this may burn through in which case it should be
replaced to ensure the longevity of the firebox.
Clear ash away from the base of the ash plate. Remove the old
ash plate and replace with a new one. When positioning the
new ash plate, ensure that the front top edge is flush against
the inside edge of the firebox beneath the door
2.5. ADJUSTING THE DOOR
If the door does not close firmly, the latch can be adjusted.
The latch is fastened onto the door with two removable
washers. Use a socket wrench to undo the M12 nut, then
remove one of the washers directly beneath the nut. Securely
fasten latch assembly again.
Close the door with the door handle to test for any
improvement. If no improvement, remove second washer.
2.6. REPLACING DOOR GLASS
This task may be easier with the door removed from the
appliance and laid horizontally on a work-bench.
To replace the door glass:
1) Two stainless steel strips hold the glass in place. Remove
the four screws from the stainless steel strips with a
3mm hex key.
2) Take out the glass, and check if the grey rope beneath
needs replacing. If so, replace this rope as well.
3) Position the new glass on top of the grey rope and re-fit
the stainless steel strips and screws.
4) Take extra care not to over-tighten the screws, otherwise
the glass will crack when the heater gets hot and the
door expands.
5) Dispose of the old glass in a responsible manner.
2.7. REPLACING THE DOOR SEAL
This task may be easier with the door removed from the
appliance and laid horizontally on a work-bench.
1) Remove any remains of the old seal from the door.
2) Clean out the groove in the door that the seal was
bedded in, using a flat head screw driver or equivalent.
3) Run a thin bead of clear roof and gutter silicone along the
groove.
4) Starting at one end, press the new door seal into the
groove on the door.
5) Refit the door if it has been removed.
