ENGLISH
IRREGULARITY
Corrosion inside the boiler.
Soot at chimney outlet.
The burner goes into lock-out (red
light on). The fault is in the flame
control device.
The burner goes into lock-out
spraying liquid fuel but the flame
does not ignite (red light on).
The trouble is in the ignition device,
providing the fuel is not polluted
with water or other impurities and
sufficiently atomised.
The equipment goes into "lock-
out", gas flows out, but there is no
flame (red light on). Fault in ignition
circuit.
POSSIBLE CAUSE
1 Boiler operating temperature too low
(below the dew point).
2 Smoke temperature too low,
approximately below 130 °C for diesel.
1 Excessive cooling of smoke
(approximately below 130°C) in the
chimney, for an outside chimney not
adequately heat insulated or cold air
infiltration.
1 Photoresistor severed or fouled with
smoke.
2 Insufficient draught.
3 Flame detector circuit interrupted in the
equipment.
4 Dirty flame disk and diffuser.
1 Ignition circuit severed.
2 The ignition transformer cables are
discharging to ground.
3 The ignition transformer leads are not
properly connected.
4 Ignition transformer is faulty.
5 The electrode faces are not at the right
distance.
6 Electrodes discharge to earth because
they are dirty or their insulation is
cracked: check also the porcelain
insulator terminals.

REMEDY
1 Increase the operating temperature.
2 Increase diesel flow rate is the boiler
allows it.
1 Improve insulation and close any opening
letting cold air into the chimney.
1 Clean or replace.
2 Check all the smoke ducts in the boiler
and in the chimney.
3 Replace the equipment.
4 Clean.
1 Check the entire circuit.
2 Replace.
3 Restore the connection.
4 Replace.
5 Return to the required position.
6 Clean and if necessary replace them.
