10. Malfunctions
If problems should occur with the use of the stove the cause can possibly be found below. If not,
then you are always welcome to contact your dealer.
The stove is difficult to control – it burns too fast: If the stove is new, then check that the
directions have been followed. If the stove is more than 1 year old or if it has been used heavily,
then the jointings may need to be changed. If the jointings sit for too long the heat makes them
lose their ability to keep the stove sealed. Check your firewood, if it is too dry it may burn too fast/
powerfully.
If there is heavy draught in the chimney it may be necessary to fit a damper in it.
The stove has poor draught after installation: Check that the mounting instructions have been
followed. It is especially the conditions surrounding the chimney that may cause problems. Are
diameter and length okay, is it sealed, are smoke pipe and junctions sealed? Is the cleaning hatch
sealed? You may need to contact a chimney sweep to remedy the problem as the chimney may be
blocked.
Smoke and soot smell: This can be caused by down-draught in the chimney and most often
happens in specific wind directions. The chimney may be too short for the ridge or surrounding
trees.
Remember not to open the door while there are flames.
The stove is difficult to light and may die out: There may be a number of causes. The most
typical are that the firewood is too wet, the damper is not sufficiently open, the draught in the
chimney is too small or maybe it is blocked or leaking. The ember layer was too small/incinerated
and did not give enough heat to light the logs (see point 7.5). Possibly give some start-up air to the
fire by opening the damper. Then the damper has to be closed again. Depending on the problem it
may be necessary to contact the dealer or a chimney sweep.
The glass soots up: The wood is too moist, Lack of draught in the chimney or wrong firing.

12. Good advice for the wood-burning stove
If the stove has not been used for a long time the chimney should be checked for possible
blockage before lighting. Furthermore it is a good idea to remove any dust from the wood-burning
stove as it might smell after a long break.
If a regulation or smoke damper has been fixed to the chimney it should not close of more than
80% of the internal diameter of the chimney.
