Other possible faults
Cause
Corrective actions
Short burning time
Incorrect or fuel with too low
calorific value (e.g. softwood)
 Use required fuel or
hardwood
The feed pressure (flue draft) is
too high.
 Call for service
Boiler pulsates
Too much fuel gas, which cannot
be burned and removed
 Check fuel dimensions
 Call for service
Incorrect air intake
 Check the tightness of the
test openings and doors
 In case of leakage, call for
service
Too long loading of the buffer
The boiler capacity is for the
application too small.
 Call for service
The hydraulic system is faulty.
 Call for service
The heating behaviour is faulty.
 Adjust the heating behaviour
to the heat demand
Excessively condensate is
formed in the chimney.
The chimney insulation is
insufficient.
 Call for service
The exhaust gas collector or the
exhaust system is leaking.
 Check test openings and
exhaust ports and if
necessary seal them
Cracks in the firebricks
The components contain a certain
amount of residual moisture.
(Note: Minor edge abrasion,
surface abrasion, crack formation
etc. does not lead to malfunction
and therefore does not constitute
a warranty)
 For wide cracks or broken
out pieces, which extend to
the boiler construction: Call
for service
