IRREGULARITY
The burner goes into lock-out
spraying liquid fuel but the flame
does not ignite. (red light on).
The burner goes into “lock-out”, gas
flows, but there is no flame (red light
on).
Burner pump noisy.
POSSIBLE CAUSE
1 Pump pressure is not regular.
2 Water in the fuel.
3 Too much combustion air.
4 Air passage between flame disk and
diffuser excessively closed.
5 Nozzle worn out or dirty.
1 Air - gas ratio incorrect.
2 Gas pipe has not been properly bled of air
at the first ignition.
3 The gas pressure is insufficient or exces-
sive.
4 Air passage between flame disk and
diffuser too closed.
1 Pipe diameter too small.
2 Air infiltration in the pipes.
3 Dirty fuel filter.
4 Excessive distance and/or difference in
level between the tank and the burner or
numerous accidental leakages (elbows,
curves, bottlenecks, etc.)
5 Deteriorated flexible pipes.
REMEDY
1 Adjust.
2 Drain water from the tank using a suitable
pump. Never use the burner pump for this
purpose.
3 Reduce combustion air.
4 Correct the position of the combustion head
adjusting device.
5 Clean or replace.
1 Correct the air - gas ratio.
2 Bleed the gas pipe again, with due caution.
3 Check the maximum gas pressure value at
the time of ignition (use a water pressure
gauge, if possible).
4 Adjust the flame disk - diffuser.
1 Replace it according to the instructions.
2 Check and eliminate infiltrations.
3 Remove and wash.
4 Adjust the length of the suction pipe to redu
-
ce the distance.
5 Replace.
