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.

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.
