LOW HEAT OUTPUT
The heat output of the appliance can be reduced by
closing the air control (sliding all the way counter-
clockwise) which will restrict the oxygen supplied to the
fire and slow down the rate at which the wood burns.
This setting provides the best energy efficiency as the
wood burns for longer. However, if not operated correctly it
may worsen emissions.
Prior to closing the air control, ensure that the fire is
burning briskly. This may require opening the air control
fully for 5-10mins before shutting down.
For the optimum between clean burning and getting
the best in efficiency, slide the air control to the middle
position.
The air control can be adjusted to any position depending
on desired heat output versus burn time.
5.3.
RELOAD WITH MORE WOOD
1.
Open air control 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 air control fully open, and leave for
minimum of 10 minutes to allow the fresh wood to
catch.
6.
After 10 or more minutes, the air control 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/damp, or have moss/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.
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.
6.2.
FLUE DRAUGHT
The flue has two main functions:
1.
To safely 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.
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
