MAINTENANCE
PROBABLE CAUSE
1) Photoresistance is cut off or dirty with
smoke.
2) Insufficient draught.
3) The photo-resistance circuit is broken.
4) Dirty disk or mouth.
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) 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) 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 op-
posite direction as that indicated by the ar-
row.
RIMEDY
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) Increase combustion air.
2) Clean or replace it.
3) Clean them.
4) Bring it to the prescribed value.
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 su-
itable pump
(never use the burner pump to carry out
this operation).
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.
