TYPE OF IRREGULARITY
The burner goes to lock-out with the
flame on (Red lamp on).
The trouble is in the flame control de-
vice.
The burner goes to lock-out spraying
fuel but the flame does not ignite (Red
lamp on).
The trouble is in the ignition device,
providing the fuel is in a good condi-
tion (not polluted) with water or other
impurities) and sufficiently atomized.
The burner goes to lock-out spraying
fuel but the flame does not ignite (Red
lamp on).
The burner goes to lock-out without
spraying fuel (Red lamp on).
Noisy burner pump
Burner does not start
POSSIBLE CAUSE
1) Photoresistance severed or fouled
with smoke
2) Insufficient draught
) Photoresistant-cell circuit severed
4) Fouled disk or orifice
1) Ignition circuit severed
2) The ignition transformer leads have
dried up
) The ignition transformer leads are not
properly connected
) Ignition transformer severed
5) The electrode tips are not at the cor-
rect 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
) Too much combustion air
4) Air passage between the disk and
orifice closed too much
5) Nozzle worn out or fouled
1) One phase missing
2) Electric motor inefficient
) Gas oil not reaching the pump
4) No gas-oil in the tank
5) Gate valve on the suction pipe closed
6) Nozzle clogged
7) Motor (three-phase) rotates in the
wrong direction (see arrow)
8) Bottom valve leaking or jammed
9) Defective pump
10) Inefficient solenoid valve
11) Voltage too low
1) Pipe diameter too small
2) Air infiltration in the pipes
3) Dirty filter
4) Excessive distance between the tank
and the burner or a lot of accidental leak-
age's (elbows, curves, choking etc.)
5) Deteriorated flexible pipes
1) Thermostats (boiler/room) or pressure
switches open
2) Photoresistant-cell in short circuit
3) No voltage with an open isolating
switch or with a tripped max. contactor
switch or line voltage failure
4) Thermostat line not wired according to
diagram or open thermostats
5) Trouble inside the control box

REMEDY
1) Clean or replace it
2) Check all the smoke ducts in the boiler
and in the chimney
) Replace the unit
) Clean
1) Check the entire circuit
2) Replace them
) Tighten them
) 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 suit-
able pump (never use the burner for
this job).
) Reduce the amount of combustion air
4) Rectify the position of the combustion
head adjusting device
5) Clean or replace it
1) Check the supply line
2) Repair or replace it
3) Check the suction pipe
) Fill up
5) Open it
6) Remove and clean it thoroughly
7) Change one phase in the
supply switch
8) Remove and clean it
9) Replace it
10) Check and replace, if necessary
11) Contact the electric company
1) Replace it according to instructions
2) Check and eliminate infiltration's
3) Remove and wash it
) Adjust the length of the suction pipe
and shorten its distance
5) Replace them
1) Raise the setting or wait until they
close owing to natural temperature or
pressure drop
2) Replace it
3) Close the switches or wait for voltage
reactivating
4) Check the connections and the ther-
mostats
5) Replace it
