Appendix 4: Diagnostic diagram
Problem
Wood does not keep burning
Gives off insufficient heat
Smoke emissions into the room when adding wood
Fire in appliance is too intense, is hard to adjust
Deposit on the glass
Possible cause
Possible solution
Insufficient draught
A cold flue usually fails to create sufficient draught. Follow the
instructions for lighting in the "Use" chapter; open a window.
Wood too damp
Use wood with no more than 20% moisture.
Pieces of wood too big
Use small pieces of kindling. Use split logs no larger than 30 cm in
circumference.
Wood stacked up incorrectly
Stack up the wood in a way that allows an adequate air flow between
the logs (open stacking, see "Burning wood")
Chimney does not work properly
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).
Chimney stack incorrect
Sufficiently high above the roof, no obstacles in its vicinity
Air inlets set incorrectly
Open the air inlets completely.
Appliance connected to chimney
incorrectly
Connection should be hermetically tight.
Vacuum in area where appliance is
installed
Switch off extraction systems.
Insufficient supply of fresh air
Provide an adequate air supply; if necessary use connection to
outside air.
Adverse weather conditions?
Inversion (reversed air flow in chimney
because of a high outside temperature),
extreme wind velocities
We recommend you don't use the appliance in the case of inversion.
Install an extra hood on the flue to increase the draught if need be.
Draught in the living room
Avoid draught in the living room, do not place the appliance near a
door or heating air ducts.
Flames touch the glass
Make sure the wood does not lie too close to the glass. Slide the
primary air inlet cover closer to the "Closed" position.
Appliance is leaking air
Check the door seals and the appliance joints.
