ANOMALY
Corrosion inside the boiler.
Soot at the mouth of the chimney.
The burner goes into lock-out (red
light on). The fault is in the flame
control device.
The burner goes to shut down
spraying liquid fuel but without flame
presence (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 Photoresistance severed or fouled
with smoke.
2 Insufficient draught.
3 Flame detector circuit interrupted in
the equipment.
4 Dirty deflector disk and diffuser.
1 Ignition circuit severed.
2 The ignition transformer cables are
discharging to ground.
3 The ignition transformer cables are
not well 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.
