Interruption of operation
Smoke formation around the door
This may be due to insufficient draft in the chimney <12Pa
• Check whether the flue or chimney is blocked
• Check whether the extraction hood is switched on and, if so, switch it off and
open a window/door near the stove for a short period.
Soot on glass
May be caused by
• excessively wet firewood
• the damper regulation is too low
Ensure the proper heating of the stove when firing up, prior to closing the door
Stove is burning too strongly
Possible causes
• may be leaks around the door seal
• chimney draught too strong > 22 Pa, a draught control regulator should be in-
stalled.
Stove is burning too weakly
Possible causes
• may be insufficient amount of wood
• insufficient air supply for room ventilation
• unclean smoke channels
• leaky chimney
• leakage between chimney and flue
Weak draught in the chimney
Possible causes
• may be that the temperature difference is too too low, e.g. due to poorly insulated
chimney
• outside temperature is high, e.g. in the summer
• no wind
• the chimney is too low and sheltered
• false draught in the chimney
• chimney and flue pipe are blocked
• the house is too dense (lack of fresh air intake).
• negative smoke extraction (poor draught conditions)
In the case of a cold chimney or difficult weather conditions you can compensate by
adding more air to the stove than usual.
If your stove continues to malfunction, we recommend that you contact your RAIS
distributor or chimney sweep.
