HOW TO FIND THE CAUSES OF BURNERS IMPROPER OPERATION AND HOW TO RECTIFY THEM
TYPE OF IRREGULARITY
The burner goes to lock-out with the flame
on (Red lamp on). The trouble is in the
flame control device.
T h e b u r n e r g o e s i n t o l o c k -
o u t s p r a y i n g l i q u i d f u e l b u t t h e
flame does not ignite (red light on).
The trouble is in the ignition device, pro-
viding the fuel is in a good condition (not
polluted with water or other impurities) and
sufficiently atomized.
The burner goes into "lock-out", gas flows,
but there is no flame (red light on). Fault in
ignition circuit.
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).
Noisy burner pump.
POSSIBLE CAUSE
1) Photoresistance severed or fouled with
smoke
2) Insufficient draught
3) Flame detector circuit interrupted
4) Dirty disk or head
1) Ignition circuit severed.
2) The ignition transformer leads have dried
up.
3) The ignition transformer cables are not well
connected.
4) Ignition transformer severed.
5) The electrode tips are not at the correct
distance.
6) Electrodes discharge to earth because they
are dirty or their insulation is cracked: check
also underneath the insulator clamps.
1) Pump pressure is not normal
2) Water in the fuel
3) Excess combustion air
4) Air passage between disk and blast tube
5) Nozzle worn out or fouled
1) Air/gas ratio incorrect.
2) Gas piping has not been properly bled of
air (in the case of first ignition).
3) The gas pressure is insufficient or exces-
sive.
4) Air passage between disk and head too
narrow.
1) Pipe diameter too small
2) Air infiltration in the pipes
3) Dirty filter
4) Excessive distance between the tank and
the burner or many accidental leakages
(elbows, curves, choking etc.)
5) Deteriorated flexible pipes

SOLUTION
1) Clean or replace it
2) Check all the smoke ducts in the boiler and
in the chimney
3) Replace the unit
4) Clean
1) Check the entire circuit
2) Replace them
3) Tighten them
4) Replace it
5) Re-set them in the required position
6) Clean or replace them, if necessary
1) Re-set it
2) Remove it from the tank with a suitable
pump (never use the burner pump for
this job)
3) Reduce combustion air
4) Rectify the position of the combustion head
adjusting device
5) Clean or replace it
1) Check and adjust 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 disk/head opening.
1) Replace it according to instructions
2) Check and eliminate infiltration's
3) Remove and wash it
4) Adjust the length of the suction pipe and
shorten its distance
5) Replace them
