We do not recommend stoking with painted, laminated or impregnated wood, wood
with a synthetic surface, painted refuse wood, chipboard, plywood, domestic waste,
paper briquettes
and pit coal, as this will produce malodorous smoke, which could be poisonous.
When firing with the above-mentioned items and amounts larger than those recommended,
the stove
is subjected to a larger amount of heat, which results in a higher chimney temperature and
lower efficiency. This can result in the stove and chimney becoming damaged and would void
the warranty.
The calorific value of the firewood is closely connected to the moisture level of the firewood.
Moist firewood has a low heat
value. The more water the wood contains, the more energy it takes for this water to vaporise,
resulting in this energy being lost.
ONLY USE RECOMMENDED FUELS
The following table shows the calorific value of different types of wood, which have been
stored for 2 years,
and which have a residual moisture of 15-17%.

1 kg of wood yields the same heat energy irrespective of wood type.
1 kg beech merely takes up less space than 1 kg of fir.
Drying and storage
Drying wood takes time. Proper air drying takes approx. 2 years.
Here are some tips:
• Store the wood sawn, split and stacked in an airy, sunny place, which is protected against
rain (the south side of the house is particularly suitable).
• Store the firewood stacks at a hand’s breadth apart, as this ensures that the air flowing
through takes the moisture with it.
• Avoid covering the firewood stacks with plastic, as this prevents the moisture from escap-
ing.
• It is a good idea to bring the firewood into the house 2-3 days before you need it.
