well, turn the regulator (1) to middle position.
If the fire goes out when the regulator is turned, return it to maximum position again until the fuel catches
fire and then turn it to middle position again. Allow the kindling to burn up completely until there are no
longer any visible flames. The stove can then be stoked again.
Important! The ash pan must not be opened during the lighting stage and must always be kept closed
when the stove is lit or the automatic air regulation will not work. Only open the door when lighting the
stove, refuelling it and cleaning it.
Stoking (drawing E)
When no more yellow flames are visible and a suitable layer of embers has built up, the stove can be
stoked again. There is a suitable layer of embers when the bottom of the stove is covered completely
and the embers are glowing in a circle around the shaking grate. Put at least two pieces of wood into the
stove, weighing up to 1 kg each. Do not regulate the stove again as the automatic system will do this, but
the temperature can be adjusted with the regulator (1). Turning it to minimum (counter-clockwise) will
reduce the rate of combustion and make the stove burn slower. Turning to maximum (clockwise) will
increase the rate of combustion and make the stove burn faster. Wait until the layer of embers is suitably
low before stoking again.
During combustion, the outer surfaces of the stove will become hot, and due care must
therefore be shown.
Fuelling with coal, patent fuel or carbonised coal
The stove is not designed for fuelling with coal and carbonised coal. However, briquettes can be used to
fuel the fire and should be placed on the embers produced by the burned wood. Turn the regulator to
its full clockwise position until the briquettes fully ignite.
Remember that the regulator must then be turned to the left again.
Be aware that using fuels other than wood, will cause soot to form on the glass pane.
F
IrIng In general
Rapid or fierce heat
Rapid or fierce heat is obtained by burning many small pieces of wood.
Maximum amounts of fuel:
The maximum allowed amount of fuel per hour is:
Wood: 2.0 kg
If these limits are exceeded, the stove will no longer be covered by the factory guarantee, and it may also
become damaged due to excessive heat. The stove has been approved for intermittent use.
Typical re-firing interval
Typical re-firing interval at nominal performance
Wood: 65 min
Long burning times
For the slowest possible combustion, turn the regulator counter-clockwise (to the left). By turning the
regulator all the way to the left, the stove receives no primary air (the air that comes through the grate).
The stove cannot be lit after a new firing without the regulator being turned to the right, which allows
