Possible cause
Background
Solution
Fuel unsuited
Wood logs are to big
Wood is damp or wet
Fire chamber temperature
too low
Only dry wood gives high ig-
nition temperature with de-
sired heat emission.
Combustion air not sufficient Without sufficient combus-
tion air supply bad igniting
and flow.
Control the position of the
push rod
Weather or the situation of
the chimney influences the
necessary exhaust of the
gases.
Check the chimney draught in
general
In case of important distur-
bance, change the chimney
or install an exhaust gas ex-
tractor
Creosote in or damage to
the chimney reduces the
necessary draught.
Clean the chimney and the
connection pipes and exam-
ine them for tightness and
damage.
Draught not available or not
sufficient
Check whether other stoves
or fireplaces are connected
to the chimney.
The chimney draught can be
worsened by other connected
fireplaces.
