LOW HEAT OUTPUT
The heat output of the appliance can be reduced by
closing the top air slide (slide to the right) which will restrict
the oxygen supplied to the fire thereby slowing down the
rate at which the wood burns.
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.
Prior to closing the air slide ensure that the fire is burning
briskly. This may require leaving the air slide fully open for
10-15mins before shutting down.
For the optimum between clean burning, and getting the
best in efficiency from the heater, from the fully closed
position, open the top air slide 4-5mm (bottom air slide is
shut).
The top air slide can be adjusted to any position so desired
depending on wanted heat output versus burn time.
Fan may be turned to low speed setting or off if the heater
is putting out sufficient heat without the fan on.

RELOAD WITH MORE WOOD
1.
Open air slide before opening door.
2.
Rake / break up any existing coals.
3.
Load the wood with the length orientated front to
back.
4.
Better results will be achieved by loading several
smaller pieces of wood rather than one large piece.
5.
Close door with top air slide fully open, and leave
for minimum of 10 minutes to allow the fresh wood
to catch.
6.
After 10 or more minutes, the top air slide can be
adjusted to the desired heat output setting.

BURNING TIPS
6.1.
FUEL QUALITY
Use wood with a moisture content of less than 20%. Logs
should not feel moist or damp, or have moss and fungal
growths.
Symptoms related to 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 the 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.
6.2.
FLUE DRAUGHT
The flue has two main functions:
1.
To remove smoke, gases and fumes from the
appliance.
2.
To provide a sufficient amount of 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.
