Fault Cause Troubleshooting Solution
Lighting problems. When the
stove is cold, smoke seeps
into the room. Once the com-
bustion chamber has heated
up, the stove burns well.
Inadequate chimney draft.
The chimney only has
sufficient draft when it is hot.
You can test using a lighter
whether flame is drawn into
the combustion chamber.
Improve the chimney.
The stove burns poorly after
the warm-up phase,
and
the glass slowly soots up.
Soot in the flue pipe. Check the flue pipe regularly,
as the problem arises slowly.
Clean regularly, and limit the use
of horizontal flue pipes. Do not use
firewood which generates large
quantities of ash.
If the stove burns poorly
after start-up, and the
glass slowly soots up.
Inadequate chimney draft.
The fault usually already occurs during
lighting. Measure the chimney draft
.
Improve the chimney draft.
Insufficient air supply. Check the air supply. Read the operating instruc-
tions and instruct all users.
Damp wood. Use clean, dry wood with a maxi-
mum moisture content of 20%.
Firewood should ideally be dried
for at least one year after splitting.
Firewood pieces too large. Optimal size – see the section for
firewood, max. diameter 10 cm.
Use smaller pieces of firewood.
Insufficient air supply to
the room. Range hoods,
airtight windows, etc.
Ensure there is sufficient fresh air
supply, open a window, check the
outdoor air supply.
Depending on the cause, win-
dows must be opened or the
outdoor air connection cleaned.

Depending on the cause, win-
dows must be opened or the

The vermiculite in the
combustion chamber is
becoming very worn.
Wood and flue gases wear
down the vermiculite.
Investigate whether the wear is
normal.
Normal wear and minor cracks
are of no significance. It should
be replaced when the steel of the
combustion chamber is visible.
Too rapid combustion. Too much chimney draft. T
o test, you can open the cleaning
hatch, but remember to close it again.
Measure the chimney draft and install
a damper in the flue pipe if necessary.
The door or ash pan/
drawer seal is defective.
While cold, close a piece of paper
in the door – the seal should hold
the paper gently in place so it does
not fall out by itself. Normal wear.
Replace the seal.
The vermiculite in the
combustion cham-
ber is cracked.
Shocks or impacts while
adding firewood.
Normal wear Cracks only have cosmetic signifi-
cance. Replace when the steel of
the combustion chamber is visible.
Steel surfaces in the
combustion chamber
have oxidised.
The temperature in the
combustion chamber is
too high.
Unsuitable fuel is being used
(such as coal). Check the qu-
antity of firewood being used,
read the operating instructions.
If there are clear cracks or
weak-nesses in the stove
body, it must be replaced.
The stove whistles Too much chimney draft To test, you can open the cleaning
hatch, but remember to close it again.
Install a damper.
The stove 'clunks' Usually due to tension
in the metal plates.
Generally only occurs while hea-
ting up and cooling down.
Adjust the metal plates.
The stove ticks Normal expansion and
contraction due to
temperature changes.
A normal sound. Ensure that the temperature
in the combustion chamber is
as constant as possible.
The stove creaks. The temperature in the com-
bustion chamber is too high.
Use less firewood. Also check the seal
in the ash pan/drawer.
See the operating instructions.
The stove smells.
The surface is steaming.
The paint on the stove sur-
ace is not yet fully hardened.
See the operating instructions
regarding the first firing.
Ensure there is sufficient ventilation.
Condensation in the
combustionchamber.
Moisture in the vermiculite. C
heck the condition of the vermiculite.
Evaporates by itself after the
stove has been lit a few times.
Damp wood. Measure the moisture content. Use dry firewood.
Condensation from
the flue pipe.
The pipe is too long or
the chimney is too cold.
Check the flue pipe's length and heat
loss.
Improve the flue pipe, insulate the
chimney.
Damp wood Measure the moisture content. Use dry firewood.
