HOW TO USE THE RANGE CORRECTLY
First fire
A new wood burning range should be fired with care
during the first few occasions. That makes the heat-
resistant colour more durable. There may also be a
slightly unpleasant smell at the first firing. This is normal
and due to the fact of excess paint or oil coating remains
on the range. The smell will disappear at the first firing
and will not return.
Firewood
The best heat value is obtained from split birch wood.
Leafy trees generally burn calmer than conifer wood,
which creates a more even heat. If you are burning
oak, beech or other wood with high heat value, always
mix the wood with other wood. Otherwise you risk
damaging your hearth. The wood must be dry, with
preferably 15-20% moisture content. With a normal fire,
approximately 1.5-2 kg wood / hour is a suitable amount
of wood. 1 kg birch wood produces about 4 kW power.
Lighting the fire
Fully open the supply air valve (butterfly valve under the
range door). Place briquettes in the centre of the hearth.
Pile up about 1.5 kg of small wood logs crosswise, like a
log house, on top of the briquettes. Start by lighting the
briquettes. These should in turn ignite the wood. Keep
the hearth door open during the first few minutes until
the wood is properly ignited. Depending on the chimney
draft, you may need to have to leave the door open
slightly longer to build a temperature in the hearth and
get a satisfactory chimney draft. Then close the door
and adjust the valve to the desired intensity of the fire.
The range should be properly heated before starting to
reduce the air supply.
Adding firewood
When the intensity of the fire has decreased, it is time to
replenish. Open the door carefully. That way, you avoid
smoke gusts. Use a fireplace tool or a piece of wood
to distribute ash and glow. Replenish with 2-4 logs and
close the door when the wood has ignited properly (1.5-2
kg wood). Firewood should only be refilled when there is
only embers in the combustion chamber (no flames). After
the fuel refill, the hearth door must be kept half-open
until the wood has ignited properly.
WARNING!
Make sure the logs don’t get too close to the door.
Otherwise, ember and ashes may fall out when the door
is opened.
Continuous fire
In order to kindle the fire correctly, it is necessary
to achieve as high a temperature as possible in the
hearth. Then you’ll have a clean combustion and get
the most out of the range and the firewood. With clean
combustion, you avoid soot coating in the hearth and
on the glass. When used correctly, the smoke will not be
visible when the range has heated up.
Operation during season change
For operation during seasonal change, that is, at higher
ambient temperatures than 15°C, the sudden change
in outdoor temperature can change the pressure in the
flue gas shaft, so that the combustion gases are not
completely discharged. The range should then be filled
with less firewood at a time and have the butterfly valve
open (position 1) so that the fuel burns faster and thus
stabilizes the outlet pressure.
