INSTRUCTIONS FOR DETERMINING THE CAUSE LEADING TO
IRREGULARITIES IN THE BURNER OPERATION AND THEIR ELIMINATION
ENGLISH
MALFUNCTION NATURE
POSSIBLE CAUSE
REMEDIES
The equipment shuts the flame down (red
light lid) the fault is limited to the flame
control device.
1) UV photocell severed or fouled with smoke
2) Insufficient draft
3) UV photocell circuit severed
4) Fouled disk or opening
1) Clean or replace it
2) Check all the smoke ducts in the boiler and
in the chimney
3) Replace the equipment
4) Clean them
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 condition
(not polluted) with water or other
impurities) and sufficiently atomised.
1) Ignition circuit interrupted.
2) The ignition transformer leads discharge
to ground.
3) Ignition transformer leads not properly
connected.
4) Ignition transformer failure.
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 under the porcelain insulator clamps
1) Check the entire circuit
2) Replace them
3) Connect them
4) Replace
5) Return to the required position
6) Clean or, if necessary, replace
The burner goes into lock-out spraying
fuel but the flame does not ignite. (red
light on).
1) Pump pressure is not regular
2) Water in the fuel
3) Too much combustion air
4) Air passage between the disk and orifice
closed too much
5) Nozzle worn out or dirty
1) Adjust it
2) Remove it from the tank with a suitable
pump (never use the burner for this job).
3) Reduce the amount of combustion air
4) Correct the position of the combustion
head regulation
5) Replace or clean
The burner goes to lock-out without
spraying fuel (Red lamp on).
1) Missing phase
2) Electric motor inefficient
3) 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) Foot valve leaks or is jammed
9) Defective pump
10) Voltage too low
1) Check the supply line
2) Repair it or replace it
3) Check the suction pipe
4) Fill it up
5) Open it
6) Remove it and clean it thoroughly
7) Change one phase in the supply switch
8) Dismantle and clean
9) Replace
10) Contact the electric company
Noisy burner pump.
1) Pipe diameter too small
2) Infiltrations of air into the pipes
3) Dirty coarse filter
4) Excessive distance between the tank and
the burner or a lot of accidental leakage’s
(elbows, curves, choking etc.)
5) Perished hoses
1) Replace taking care to follow the relative
instructions
2) Check and eliminate such infiltrations
3) Remove and wash it
4) Rectify the entire length of the intake pipe
and shorten the distance
5) Replace them
