TYPE OF IRREGULARITY
The burner goes to lock-out with the flame on
(Red lamp on).
The trouble is in the flame control device.
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
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
3) Photoresistant-cell circuit severed
4) Fouled disk or orifice
1) Ignition circuit severed
2) The ignition transformer leads have dried up
3) The ignition transformer leads are not properly
connected
4) Ignition transformer severed
5) The electrode tips are not at the correct dis
-
tance
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) 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
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 direc
-
tion (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 leakage’s (elbows,
curves, choking etc.)
5) Deteriorated flexible pipes
1) Thermostats (boiler/room) or pressure switches
openì
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
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 for this job).
3) 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
4) 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
4) 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 reac
-
tivating
4) Check the connections and the thermostats
5) Replace it
