Fault
Lighting problems. When the
stove is cold, smoke seeps
into the room. Once the com-
bustion chamber has heated
up, the stove burns well.
The stove burns poorly after
the warm-up phase, and the
glass slowly soots up.
If the stove burns poorly
after start-up, and the
glass slowly soots up.
The vermiculite in the com-
bustion chamber is becoming
very worn.
Too rapid combustion.
The vermiculite in the
combustion chamber is
cracked.
Steel surfaces in the
combustion chamber
have oxidised.
The stove whistles
The stove 'clunks'
The stove ticks
The stove creaks.
The stove smells.
The surface is steaming.
Condensation in the
combustionchamber.
Condensation from the flue
pipe.
Moving parts creak.
Cause
Inadequate chimney draft.
The chimney only has
sufficient draft when it is hot.
Soot in the flue pipe.
Inadequate chimney draft.
Insufficient air supply.
Damp wood.
Firewood pieces too large.
Insufficient air supply to the
room. Range hoods, airtight
windows, etc.
Insufficient air supply to the
room. Range hoods, airtight
windows, etc
Wood and flue gases wear
down the vermiculite.
Too much chimney draft.
The door or ash pan/drawer
seal is defective.
Shocks or impacts while
adding firewood.
The temperature in the
combustion chamber is
too high.
Too much chimney draft
Usually due to tension in the
metal plates.
Normal expansion and
contraction due to
temperature changes.
The temperature in the com-
bustion chamber is too high.
The paint on the stove sur-
ace is not yet fully hardened.
Moisture in the vermiculite.
Damp wood.
The pipe is too long or the
chimney is too cold.
Damp wood
Needs lubercation.

Troubleshooting

You can test using a lighter whether
flame is drawn into the combustion
chamber.
Check the flue pipe regularly, as the
problem arises slowly.
The fault usually already occurs during
lighting. Measure the chimney draft.
Check the air supply.
Use clean, dry wood with a maximum
moisture content of 20%.
Optimal size – see the section for
firewood, max. diameter 10 cm.
Ensure there is sufficient fresh air
supply, open a window, check the
outdoor air supply.
Ensure there is sufficient fresh air
supply, open a window, check the
outdoor air supply.
Investigate whether the wear is
normal.
To test, you can open the cleaning
hatch, but remember to close it again.
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.
Normal wear
Unsuitable fuel is being used (such as
coal). Check the quantity of firewood
being used, read the operating in-
structions.
To test, you can open the cleaning
hatch, but remember to close it again.
Generally only occurs while heating up
and cooling down.
A normal sound.
Use less firewood. Also check the seal
in the ash pan/drawer.
See the operating instructions
regarding the first firing.
Check the condition of the vermiculite.
Measure the moisture content.
Check the flue pipe's length and heat
loss.
Measure the moisture content.

Solution
Improve the chimney.
Clean regularly, and limit the use
of horizontal flue pipes. Do not use
firewood which generates large
quantities of ash.
Improve the chimney draft.
Read the operating instructions and
instruct all users.
Firewood should ideally be dried for
at least one year after splitting.
Use smaller pieces of firewood.
Depending on the cause, windows
must be opened or the outdoor air
connection cleaned.
Depending on the cause, windows
must be opened or the outdoor air
connection cleaned.
Normal wear and minor cracks are of
no significance. It should be replaced
when the steel of the combustion
chamber is visible.
Measure the chimney draft and install
a damper in the flue pipe if necessary.
Replace the seal.
Cracks only have cosmetic signifi-
cance. Replace when the steel of the
combustion chamber is visible.
If there are clear cracks or weak-
nesses in the stove body, it must be
replaced.
Install a damper.
Adjust the metal plates.
Ensure that the temperature in the
combustion chamber is as constant
as possible.
See the operating instructions.
Ensure there is sufficient ventilation.
Evaporates by itself after the stove has
been lit a few times.
Use dry firewood.
Improve the flue pipe, insulate the
chimney.
Use dry firewood.
Lubercate with graphite spray.
