TROUBLESHOOTING
Problem Check Remedy
The device has been stopped during a
hot start.
Check that the pellets fed into the
combustion head are whole. The fuel
consists of pieces, the burner cannot
keep up the embers. The reason for re-
curring stops may also be an excessive
play in the blocking feeder, which ma-
kes it difficult to keep up the embers.
The device has been stopped during
a cold start.
Check the function of the ignition re-
sistor, unless ignition does not succeed
after two start attempts.
If the cause of the operation cannot
be determined with certainty or the ig-
nition resistor must be replaced, con-
tact an authorised technician.
The red operation indication is on
and the display reads:
ALARM LEVEL MONITOR , or
ALARM BLOCKAGE
The cause of the problem is that
the optical flame monitor of the
burner has not detected light du-
ring a certain period of time. No
fuel has entered into the combus-
tion head.
is there fuel in the upper connection?
If there is no fuel in the upper con-
nection of the burner, check the cable
connections of the level switches. If
this does not help, wipe the level swit-
ches clean. If the external feed of the
burner does not start in spite of this
or the level switches must be cleaned
continuously, they may be defective
and, when necessary, should be repla-
ced by an authorised technician.
Problem Check Remedy
that the feed auger, blocking feeder
and burner auger rotate and are not
blocked, e.g. because of a foreign
object.
A possible foreign object in the pellet
fuel must be removed, if it gets stuck
in the blocking feeder or in one of
the feed augers. Remove the upper
connection and take out the possible
foreign object from the feed auger or
blocking feeder. In connection with the
inspection of the burner auger remove
the four augers located between the
inner and middle part and pull out the
burner auger from the tube. Be sure to
disconnect all cable connections.
