5. 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
