3. BRIEF INFORMATION ON COMBUSTIBLE - LOGS
Suitable fuels and fuel amounts
Your stove is generally suitable for burning dry firewood. You can also burn
combustibles such as wood briquettes.
Note
A stove is not a waste incinerator. The warranty lapses if waste or non-
approved materials such as plastic, treated wood (chipboard), coals or
clothes are burnt! This leads to damage to the stove and chimney and to
environmental pollution!
Note
FUEL AMOUNTS
The stove is fitted with a construction-specific flat firebox. This means only
one layer of logs may be laid on the base embers.
Please observe that adding greater quantities of logs leads to emission of
high temperatures, higher than the stove is designed for. This may cause
damage to your stove. This is reflected in particular on the glass of the
combustion chamber door, which will get a gray haze in case of overheating
the stove, which can not be removed.
Wood types
Different types of wood have different calorific values. Wood from deciduous
trees 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.

Output controlling
The output of your stove is regulated manually or via the Rikatronic-control.
Please observe that the output of your stove also depends on the chimney
draught and the amount of fuel added.
Clean combustion
1. The firewood must be dry and untreated.
The should-be value is between 14 % and 18 % relative wood moisture.
Wood has to be stored dry and ventilated for 2–3 years.
2. Correct firewood amount and size:
Q
Too much firewood leads to overheating. This can damage your stove and
increases the exhaust emission values.
Q
If you take too little firewood or if the logs you place are too large the stove
will not reach the optimum operating temperature. The flue gas values also
increase in this case.
Q
For right quantity of firewood see AMOUNT OF FUEL.
