Trouble Shooting
Problem
Reason
How to solve the problem
Poor draught.
The connection to the brick-lined
chimney is not properly tightened
Ask the chimney sweeper to check that the
connection between stove and chimney is quite
tight.
The flue tube is full of soot or the space
under the oven is full of soot.
Clean flue tube and fireplace. Remove the soot
door on the stove and scratch out the soot with
the scratcher.
The chimney is blocked, e.g. a bird nest
or similar.
The chimney is too short or the cross-
sectional area is too large.
Contact the chimney sweeper or your dealer for
further guidance.
The stove was not fired up for a long
time and the doors have been shut.
When not using the stove for a long time, keep
the change-over damper (ash-pan door) open.
Negative pressure in the room.
Open a window or fix an external wall valve close
to the stove. Check that the ventilation is properly
set.
Moisture content is too high in the
wood or the wood is too cold.
Only dry wood with a maximum moisture
content of 20 % is to be used. Keep the wood
indoors for 24 hours to have room temperature
before lighting it.
Too strong draught.
If oven dried wood is being used, it
requires less air supply then normal
wood fuel.
Reduce the air supply by adjusting the screw at
the base plate (vertical position = open. horizontal
position = closed) and also adjust the change-
over damper at the ash-pan door.
The chimney is too long.
Contact the chimney sweeper or your dealer for
further guidance.
The induced draft fan, if any, may be
too strong.
Adjust it to a lower number of revolutions or
switch it off.
Soot deposit on the
cooking plate of
glass
The moisture content of the wood is
too high.
Only dry wood with a maximum moisture
content of 20% is to be used.
The ash-pan door and/or the screw at
the base plate are closed. -
Open the dampers to supply more air for the
combustion.
Glass turns white
Poor combustion (too low temperature
in the oven).
Follow the instructions for proper lighting in this
manual.
Incorrect firing (Use of waste wood,
chipboard, pressure-impregnated,
laminated plastic, Plywood or similar)
Always use clean and dry wood.
Smoke comes out in
the room when
opening the door
Pressure equalizing in the fireplace..
First open the ash-pan door and 1 minute later
the fireplace door. Avoid opening the door too
quickly, but always slowly.
Poor chimney draught.
Check that the height of the chimney is not too
short relatively to required minimum draught for
the stove.
The door was opened when the fire is
still burning in the fireplace.
Only open the door when the wood has turned
to glowing embers.
White smoke
The combustion temperature is too low. Increase the air supply by opening the ash-pan
door and setting the screw at the base plate.
The wood is too damp and contains
water vapour.
Always use clean and dry wood.
Black or greyish
black smoke
Insufficient combustion.
Increase the air supply by opening the ash-pan
door and setting the screw at the base plate.
Difficulties in starting the fire in most cases are the result of using wood
with too high humidity content, too poor draught or untight chimney
connections.
