4.5 HEATING IN THE TRANSITIONAL PERIOD / UNFAVOURABLE
WEATHER CONDITIONS
In the transitional period, meaning when the outside temperature
is still high (above approx. 15 °C) or during unfavourable weather
conditions (katabatic winds etc.), it is possible to experience dis-
ruption to the chimney flue performance during sudden rises in
temperature so that the hot gasses are not completely extracted. In
these circumstances, the fireplace should only be filled with a low
volume of fuel and the air damper is to be operated at its highest
setting. This will result in the existing fuel burning quicker (with a
greater development of flames). As a result, the performance of
the chimney flue should stabilise. In order to avoid resistance in
the bed of embers, the ash should be carefully taken off at regular
intervals. After the chimney has stabilised, the air intake feed can
be reduced a little (to around the medium setting).
5. FUEL
Fireplaces may only be operated using fuels that correspond to the
1st BlmSchV regulations. Only firewood (recommended residual
moisture 20 % or less) or wood pellets according to DIN 51731 are
permissible for use in stoves.
Incidentally: A measuring device for determining the moisture of
firewood does not cost very much and quickly pays off.
No other type of fuel may be used!
Therefore, it is not permissible to burn the following:
• Varnished or plastic-coated wood
• Chipboard or wood that has been treated with wood preservatives
• Wood originating from Europool palettes
• Waste, household rubbish and old clothes
• Paper, paper briquettes, cardboard
• Coal, coal briquettes, brown coal
• Damp wood (residual moisture over 25 %)
• Plastics / foam material of any sort
• Solid or liquid materials damaging to wood
It is prohibited to burn these and other unsuitable materials in your
stove. If materials other than the approved fuels of firewood or wood
briquettes according to DIN 51731 are burnt, this can lead to the
formation of dangerous gasses and disruption to the burning process
right through to deflagration.
The guarantee is rendered void if the stove is operated using non-
approved fuels.
Use small pieces of wood to get the fire going. Only used chopped
wood as a fuel that is no thicker than approx. 8 cm at its thickest
point. The optimal length of the wood is approx. 25 cm. Do not add
too much wood to the fire for continuous heating; it is preferable to
add small volumes of wood.
