Some advice in case of combustion problems
Error Explanation Solution
No draught
The chimney is blocked
Contact a chimney sweeper / dealer for more information or
clean the ue and burn chamber
The ue is sooty or there is accumulated soot on the
smoke bafe
The smoke bafe is wrongly positioned
The insert
release
smoke when
lighting the
re and during
combustion
Downdraught in the room caused by no draught, that
the house is too “air tight”.
Is veried by lighting the re with an open window. If this helps,
more/bigger vents must be installed.
Downdraught in the room – caused by extractor and/
or central ventilation system that pulls too much air
out of the room.
Turn off/regulate extractor and/or other ventilation. If this helps,
more/bigger vents must be installed.
The ues from two replaces/stoves are connected to
the same chimney at the same height.
One ue must be repositioned. The height difference of the two
ue pipes should be of at least 30 cm.
The ue is in a declining position from the smoke
dome to the chimney.
The ue must be moved so that there is an inclination of at
least 10º from smoke dome to chimney. Possibly install a
smoke suction device.
The ue is too far into the chimney.
The ue must be remounted. Should end 5 mm before the
chimney inner wall. Possibly install a smoke suction device.
Soot hatch in the basement or attic that is open and
thus creating a false draught.
Soot hatches must always be closed. Hatches that are not tight
or defected must be changed.
Damper/top draught vents or doors on replaces that
are not in use are open and create a false draught.
Close damper, doors and top draught vents on replaces that
are not in use.
An open hole in the chimney or a replace that has
been removed, thus creating a false draught.
Holes must be completely closed.
Defect masonry in the chimney, e.g. it is not airtight
around the ue pipe entry and/or broken partition
inside the chimney creating a false draught.
Seal and plaster all cracks and sites that are not tight.
The cross-section in the chimney is too large which
results in no or very low draught.
The chimney must be retted, possibly install a smoke suction
device.
The cross-section in the chimney is too small and the
chimney cannot carry out all the smoke.
Change to a smaller replace or build new chimney with larger
cross section. Possibly install a smoke suction device.
The chimney is too low and hence a poor draught. Increase the height of the chimney.
The replace
release smoke
inside when
it is windy
outside.
The chimney is too low in relationship to the
surrounding terrain, buildings, trees etc.
Increase the height of the chimney. Possibly install a chimney
cap or a smoke suction device.
Turbulence around the chimney due to the roof being
too at.
Increase the height of the chimney or install a chimney cap.
The replace
does not heat
sufciently.
The replace combustion receives too much oxygen
due to a leakage under the lower border of the insert
or too strong chimney draught. Difcult to regulate
the combustion and the wood burn up too quickly.
Any possible leakage must be sealed off. A draught regulator
or possibly a damper can reduce the chimney draught. NB! A
leakage of only 5 cm2 is enough for 30% of the heated air to
disappear.
Too much
draught
The smoke buffer is wrongly positioned.
Control the positioning of the smoke buffer – see assembly
instructions.
In case of using oven-dried wood, this requires less
air supply than when using normal wood.
Turn down the air supply.
The gaskets around the door are worn and totally at.
Control the gaskets and exchange them as per the assembly
instructions.
The chimney is too large. Contact chimney sweeper or other professional for more details.
The glass is
sooty
The wood is too wet. Only use dry wood with a humidity of maximum 20%.
The air vent control is too closed. Open the air vent control to add air to the combustion.
White glass
Bad combustion (the temperature is too low) Follow the guidelines in this booklet for correct heating.
Using wrong material for combustion (such as:
painted or impregnated wood, plastic laminate,
plywood etc)
Ensure to use only dry and clean wood.
Smoke comes
out of the
insert when
the door is
opened.
A levelling out of pressure occurs in the burn
cham ber.
Open the air vent control for about 1 min before opening the
door – avoid opening the door too quickly.
The door is opened when there is a re in the burn
cham ber.
Only open the door when there is hot ember.
White smoke
The combustion temperature is too low. Increase the air supply.
The wood is humid and contains water damp. Ensure to use only dry and clean wood.
Black or grey/
black smoke
Insufcient combustion. Increase the air supply.
