OPERATING ANOMALY
1) Clean or replace it.
2) Check all smoke circuits inside the boiler and
the chimney.
3) Replace the control-box.
4) To be cleaned.
1) Check the circuit completely.
2) Replace them.
3) Connect correctly.
4) Replace it.
5) Adjust them to the prescribed position.
6) Clean or, if necessary, replace them.
1) Check the feeder line.
2) Repair or replace it.
3) Check the suction pipe.
4) Fill with fuel.
5) Open it.
6) Disassemble and clean it completely
7) Invert a phase in the input switch.
1) Increase the value or wait for them to close by
natural decrease in temperature or pressure.
2) Replace it.
3) Close the contact of the switches or wait for
voltage to be supplied again.
4) Check thermo-stat connections.
5) Replace it.
1) Bring it to the expected value.
2) Decrease combustion air.
3) Clean or replace it.
4) Discharge it from the tank by using a suitable
pump (never use the burner pump to carry
out this operation).
1) Increase combustion air.
2) Clean or replace it.
3) Clean them.
4) Bring it to the prescribed value.
TYPE OF IRREGULARITY
PROBABLE CAUSE
RIMEDY
The controll-box stops with
flame (red light on) The failure
is limited to the flame-
controlling device.
The control-box stops the
burner with fuel spraying but
no flame (red light on).
The control-box stops the
burner without spraying fuel
(red light on).
The burner does not start
Defective flame with sparks.
Not well-shaped flame with
smoke and soot.
1) Photoresistance is cut off or
dirty with smoke.
2) Boiler fouled
3) Photoresistor circuit failure
4) Dirty disk or mouth.
1) The ignition circuit is broken.
2) The ignition transformer cables have
dried over time.
3) The ignition transformer cables are
not well connected.
4) The ignition transformer is cut off.
5) The electrode faces are not at theright
distance.
6) Electrodes discharge to earth since
they are dirty or with a cracked
insulation: also check under the
clamps fastening the insulating
materials.
1) There is one phase missing.
2) Insufficient electric motor.
3) Light-oil does not reach the pump.
4) No light-oil inside the tank.
5) Closed gate-valve in suction pipe.
6) Clogged nozzle.
7) Motor rotating in the oppositedirection
as that indicated by the arrow.
1) Open contact in (Boiler or room)
thermo-stats or pressure-switches.
2) Short-circuited photo-resistance.
3) There is no voltage because of the an
open contact in the main switch or the
meter overload-release, or no voltage
in the line.
4) The thermo-stats line was not carried out
according to the diagram or thermo-stats
did not close their contacts.
5) Failure inside the control-box.
1) Spraying pressure is too low.
2) Too much combustion air.
3) Insufficient nozzle since it is dirty
or worn out.
4) Water in fuel.
1) Insufficient combustion air.
2) Insufficient nozzie since it is dirty or
worn out.
3) Clogged boiler pipe or chimney.
4) Low spraying pressure.
