Appendix 4: Diagnostic diagram

Problem
Wood will not stay lit
Gives off insufficient heat
Smoke emissions into the room when adding wood
Fire in stove is too intense, is hard to adjust
Deposit on the glass
Possible cause
Insufficient draught
Wood too damp
Logs too large
Wood stacked incorrectly
Chimney does not work properly
Chimney stack incorrect
Air inlets set incorrectly
Stove connected to the chimney
incorrectly
Vacuum in area in which the stove is
installed
Insufficient supply of fresh air
Adverse weather conditions?
Inversion (reversed air flow in chimney
because of a high outside temperature),
extreme wind speeds
Draught in the living room
Flames touch the glass
Stove is leaking air
28
Possible solution
A cold flue usually fails to create sufficient draught. Follow the
instructions for lighting in the "Use" chapter; open a window.
Use wood with no more than 20% moisture.
Use small pieces of kindling. Use split logs no larger than 30 cm in
circumference.
Stack the logs in a way that allows adequate air flow between the
logs (open stacking, see "Burning wood")
Check whether the chimney meets the requirements: at least 4
metres high, right diameter, well insulated, smooth inside, not too
many bends, no obstructions in chimney (bird's nest, too much soot
deposit), hermetically tight (no chinks).
Sufficiently high above the roof, no obstacles in the vicinity
Open the air inlets completely.
Connection should be hermetically tight.
Switch off extraction systems.
Provide an adequate air supply; if necessary use outside air
connection.
We recommend you don't use the appliance in the case of inversion.
If required, install an extra hood on the flue to increase the draught.
Avoid draught in the living room, do not place the appliance near a
door or heating air ducts.
Make sure the wood is not positioned too close to the glass. Slide the
primary air inlet cover closer to the "Closed" position.
Check the door seals and stove joints.
