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
flue, smoke baffle and burn chamber.
The flue is sooty or there is accumulated soot on the
smoke baffle.
The smoke baffle is wrongly positioned.
Verify the assembly of the smoke baffle - see assembly instructions.
The insert
release smoke
when lighting
the fire and
during combus-
tion
Downdraught in the room caused by no draught, that the
house is too “air tight”.
Light the fire with an open window. If this helps, more/bigger vents must
be installed in the room.
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
vents must be installed.
The flues from two fireplaces/stoves are connected to
the same chimney at the same height.
One flue must be repositioned. The height difference of the two flue
pipes must be of at least 30 cm.
The flue is in a declining position from the smoke dome
to the chimney.
The flue 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 flue is too far into the chimney.
The flue must be reconnected so that it does not enter into the chimney
but ends 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 are
defected must be changed.
Damper/top draught vents or doors on fireplaces that are
not in use are open and create a false draught.
Close damper, doors and top draught vents on fireplaces that are not in
use.
An open hole in the chimney after that a fireplace has
been removed, thus creating a false draught.
Holes must be completely sealed off with masonry.
Defect masonry in the chimney, e.g. it is not airtight
around the flue 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 refitted, 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 fireplace or build new chimney with a 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 and/or install a chimney cap/smoke
suction device*.
The fireplace
releases 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 and/or install a chimney cap/smoke
suction device*.
Turbulence around the chimney due to the roof being
too flat.
Increase the height of the chimney and/or install a chimney cap/smoke
suction device*.
The fireplace
does not heat
sufficiently.
The fireplace combustion receives too much oxygen due
to a leakage under the lower border of the insert or too
strong chimney draught. Difficult to regulate the combus -
tion 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. Verify 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 flat. Replace the gaskets, contact your dealer.
The chimney is too large. Contact chimneysweeper 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 closed too tightly.
Open the air vent control to add air to the combustion. When new
wood logs are inserted all vent controls should be completely opened
or the door slightly opened until the flames have a good take on the
wood.
White glass
Bad combustion (the temperature is too low) Follow the guidelines in this user guide for correct combustion.
Using wrong material for combustion (such as: painted
or impregnated wood, plastic laminate, plywood etc)
Ensure to use only dry and clean wood.
Smoke is
released when
the door is
opened
A levelling out of pressure occurs in the burn chamber.
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 fire in the burn
chamber.
Open the door carefully and/or only 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
Insufficient combustion. Increase the air supply.
