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 chimney
incorrectly
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
possible solution
A cold flue usually fails to create sufficient draught. Follow
the instructions 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 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, 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
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 appliance joints.
