Appendix 4: Diagnosis diagram
Problem
Wood will not stay lit
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
Logs too large
Wood stacked incorrectly
Flue does not work properly
Chimney stack incorrect
Air inlets set incorrectly
Appliance connected to the flue incor-
rectly
Vacuum in area in which the appliance is
installed
Insufficient supply of fresh air
Bad weather
? Inversion (reversed air flow in chimney
because of a high outside temperature),
extreme wind speeds
Draught in the living room
Flames touch the glass
Appliance is leaking air
Subject to change because of technical improvements
possible solution
A cold flue usually fails to create sufficient draught. Follow the instruc-
tions for starting a fire in the 'Use' section; 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 cir-
cumference.
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, correct 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 con-
nection.
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 appliance joints.
