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

Insufficient draught
Wood too damp
Pieces of wood too big
Wood stacked up incorrectly
Chimney does not work properly
Chimney stack incorrect
Air inlets set incorrectly
Appliance connected to chimney
incorrectly
Vacuum in area where appliance is
installed
Insufficient supply of fresh air
Adverse weather conditions?
Inversion (reversed air flow in chimney
because of a high outside temperature),
extreme wind velocities
Draught in the living room
Flames touch the glass
Appliance is leaking air
24
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 up the wood in a way that allows an 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 its vicinity
Open the air inlets completely.
Connection should be hermetically tight.
Switch off extraction systems.
Provide an adequate air supply; if necessary use connection to
outside air.
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.
Avoid draught in the living room, do not place the appliance near a
door or heating air ducts.
Make sure the wood does not lie too close to the glass. Slide the
primary air inlet cover closer to the "Closed" position.
Check the door seals and the appliance joints.
