5. Shutoff flue gas temp. in Heating mode too
low (21)
Cause:
•
Temperature fell below the minimum
temperature in Heating mode operating
status
The following circumstances might lead to this:
•
No pellets present
•
The screw conveyor is not rotating, it is
jammed, the screw conveyor motor is
defective or the chute is not clear
•
The required combustion air cannot be
supplied to the stove e.g. via a vapour
extractor hood that is located in the
vicinity of the installation site and is
switched on.
•
Room too airtight – required combustion
air cannot be replenished in the room
•
Air volume sensor dirty or defective
•
Suction filter dirty
•
Burner
dirty
•
Poor seals on the pellet stove (door,
seals)
•
Flame temperature sensor defective
•
Flue gas temperature sensor defective
Correction:
¾
Check pellet stock
¾
Check that the chute between the pellet
tank and the burner is clear.
¾
Clean the burner, suction filter and air
volume sensor (paintbrush).
¾
Check whether there is a vapour
extractor hood present and whether it is
in operation
¾
Make sure for instance that a window is
left open a crack to supply the required
combustion air

Contact the service engineer
6. Shutoff flue temp. in Heating mode too
high (22)
Cause:
•
The highest permitted flue gas
temperature was exceeded
The following circumstances might lead to this:
•
Too much fuel is being supplied to the
burner
•
Flue gas temperature sensor defective
Correction:

Contact the service engineer
7. Shutoff, combustion chamber door open
(6) or (9)
Cause:
•
The door is open for longer than 1 minute
during operation
•
The damper at the bottom of the door is
