The fire extinguishes after a while
Make sure that the firewood is sufficiently dry.
Find out whether there is negative pressure in the house, close mechanical fans and open a
window close to the insert.
Check that the air vents are open;
Check that the flue outlet is not clogged by soot.
Heating in transitional periods
From an outside temperature of about 15 degrees and above, the stove may not function
properly. The small temperature differences lead to a decreasing chimney downdraught. This
can result in difficulty lighting the stove, unsatisfactory burning behaviour, increased flue gas
formation with blackening of the panel and smoke being emitted when the stove door is
opened.
Unusual amount of soot accumulates on the glass
Some soot will always stick to the glass, but the quantity depends on:
• Moisture in the fuel
• The local draught conditions
• The air vents opening
Most of the soot will normally burn off when the air vents are opened all the way, and a fire
is burning briskly in the fireplace
Chimney fire
Using incorrect or excessively moist fuel, and not having your stove regularly serviced, can
cause a chimney fire due to deposits in the chimney. Immediately close all stove air vents
and notify the fire brigade. After a chimney fire, it must be inspected for cracks and tightness
by a specialist.
Important note
Using the stove over and beyond the nominal heat output for prolonged periods and with
fuels other than those mentioned will invalidate the manufacturer's warranty.
