High Heat Output
This setting generates maximum heat output and high oven
temperatures. It is not the most energy-efficient as some heat
is lost up the flue instead of being transferred into the room.
However, once the fire has been 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 the 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.
When using the oven, ensure the bypass damper is in the
closed position, and the bottom air slide in the oven door is
closed.
To maintain constant oven temperature, have the fire
burning briskly using small pieces of wood that provide plenty
of flames.
If the temperature in the oven gets too hot, reduce the
amount of oxygen to the fire by partially closing the top air
slide. Alternatively, open the bottom door slide control in the
oven door.
If the temperature in the oven drops below that desired, open
the top air slide and add some more pieces of wood if
required.
The round hotplates in the top of the heater can be removed
for cooking purposes allowing the direct flame to a wok or
frypan. A triangular-handled tool is provided for lifting out the
round hotplates.
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.
