SUITABLE FUELS AND FUELS
QUANTITIES
Your stove is generally suitable for burning dry firewood.
You can also burn fuels such as wood briquettes.
Only use dry fuel (moisture content between 14 and 18 %).
Burning waste of any kind, particularly plastic, damages
your stove and chimney and is prohibited by the emission
reduction laws.

FUEL QUANTITIES

The stove is fitted with a construction-specific flat
firebox. This means only one layer of fuel may be laid
on the base embers.
Please observe that adding greater quantities of fuel
leads to emission of more heat and greater heating of
the stove than it is designed for. This may cause
damage to your stove.
WOOD TYPES
Different types of wood have different fuel values.
Deciduous wood is particularly suitable. It burns with
a constant flame and forms long-lasting embers.
Coniferous wood has higher levels of resin and
burns off faster, as do all softwoods, and tends to
spray sparks.

MAXIMUM FUEL QUANTITIES
Wood:
2 logs of approx. 0.6 kg
Wood briquettes (broken):
2 pieces of approx. 0.6 kg
Your stove output is regulated via the knob. This regulator
knob must be used according to your own experience
since your stove output also depends on the chimney
draught.
Use the heat-resistant glove when operating the
regulator knob.
The riddle grate lever (part 10) may only be operated
with the riddle hook.
