Solution
Fill up with oil
Check pipeline and/or main tap
Clean nozzle filter, pump filter, pre-
filter, if necessary, change nozzle
Seal off oil suctioning pipe. The oil
in the reverse flow pipe should be
free of bubbles.
Set the pressure correctly. Change
the coupling or pump (can only be
carried out by an expert).
Activate button for removing
disturbances on the control unit
(see section describing burner not
starting up)
Check the tuyere connection. Pull
out the mains plug or switch off the
power supply and check the tuyere
connection.
Unscrew the burner nozzle.
Change the nozzle for a new one.
Do not attempt to clean the nozzle!
Keep changing the nozzle,
opened, cleaned nozzles never
burn flawlessly.
Pull out the photo conductive cell
and wipe it with a clean cloth. This
cleaning should take place often in
very dusty rooms.
Check and clean all oil filters: pre-
filters, pump filters, nozzle filters.
Seal off the oil suctioning pipe,
tighten all screws. Let the oil in the
reverse flow pipe flow into a pot of
oil. It must be free of bubbles.
Set the pump pressure correctly
(can only be done by an expert).
As in "Burner starts up, but does
not ignite", dismantle the burner
nozzle and exchange for a new
one (do not clean).
