Explanation Solution
Contact a chimney sweeper / dealer for more information or clean
the flue, smoke baffle and burn chamber.
Verify the assembly of the smoke baffle - see assembly instructions.
Light the fire with an open window. If this helps, more/bigger vents
must be installed in the room.
Turn off/regulate extractor and/or other ventilation. If this helps,
more vents must be installed.
One flue must be repositioned. The height difference of the two flue
pipes must be of at least 30 cm.
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 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 hatches must always be closed. Hatches that are not tight or
are defected must be changed.
Close damper, doors and top draught vents on fireplaces that are
not in use.
Holes must be completely sealed off with masonry.
Seal and plaster all cracks and sites that are not tight.
The chimney must be refitted, possibly install a smoke suction
device*.
Change to a smaller fireplace or build new chimney with a larger
cross section. Possibly install a smoke suction device*.
Increase the height of the chimney and/or install a chimney cap/
smoke suction device*.
Increase the height of the chimney and/or install a chimney cap/

Increase the height of the chimney and/or install a chimney cap/

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.
Verify the positioning of the smoke buffer – see assembly instruc-
tions.
Turn down the air supply.
Replace the gaskets, contact your dealer.
Contact chimneysweeper or other professional for more details.
Only use dry wood with a humidity of maximum 20%.
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.
Follow the guidelines in this user guide for correct combustion.
Ensure to use only dry and clean wood.
Open the air vent control for about 1 min before opening the door
– avoid opening the door too quickly.
Open the door carefully and/or only when there is hot ember.
Increase the air supply.
