OPERATING ANOMALY
RIMEDY
1) Increase combustion air.
2) Clean or replace it.
3) Clean them.
4) Bring it to the prescribed value.
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) Fasten them.
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 comple-
tely
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).
TYPE OF IRREGULARITY
Not well-shaped flame with
smoke and soot.
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 spar-
ks.
PROBABLE CAUSE
1) Insufficient combustion air.
2) Insufficient nozzie since it is dirty or
worn out.
3) Clogged boiler pipe or chimney.
4) Low spraying pressure.
1) Photoresistance is cut off or dirty with
smoke.
2) Insufficient draught.
3) The photo-resistance circuit is bro-
ken.
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 the-
right 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 (three-phase) rotating in the
opposite direction 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 arried
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.
