Fault Cause / Cure
After several lighting attempts, the
electronic controller shuts down the
boiler. Clean the pilot burner nozzles with compressed air.
Check the regular gas flow to the boiler and that the air has been eliminated
from the pipes.
Make sure the electrodes are correctly positioned and free of deposits (see
fig. 9).
Make sure the boiler is connected to an efficient earth connection.
Check the connections at the ignition and ionisation electrodes.
The electrodes are not discharging
in the ignition phase. Make sure the electrodes are correctly positioned and free of deposits (see
fig. 9).
Control thermostat adjusted too low.
Check the power supply.
Check the connections at the ignition and ionisation electrodes.
Check the connections at the electronic flame controller.
Make sure LINE-NEUTRAL are not inverted and that the earth contacts are effi-
cient.
Check the inlet gas pressure and any open pressure switches.
Reset the safety thermostat.
Reset the fume thermostat.
Make sure the room thermostat is closed.
The burner burns poorly: flames
too high, too low or too yellow Gas valve filter dirty.

proper combustion.
Smell of unburnt gas Make sure the boiler is clean.
Check the flue draught.
Check that gas consumption is not excessive.
The boiler works but the tempera-
ture does not increase Check correct operation of the 2-stage control thermostat.
Make sure the gas valve 2nd stage operator (max. power) is fed.
Check that gas consumption is not less than that provided for.

Make sure the boiler is adequate for the system.
Make sure the heating pump is not blocked.
Temperature of water to the system
too high or too low Check correct operation of the 2-stage control thermostat.
Make sure the heating pump is not blocked.
Make sure the characteristics of the circulating pump are adequate for the sys-
tem.
Explosion at burner. Delay on igni-
tion Make sure the gas pressure is sufficient and that the boiler shell is not dirty.
The control thermostat is reacti-
vated with too great a temperature
difference Make sure the bulb is properly inserted in the sheath.
Check operation of the 2-stage thermostat .
The boiler produces condensate Make sure the boiler is not operating at too low a temperature (below 50°C).
Check regular gas consumption.
Check the efficiency of the flue.
The boiler shuts down for no appar-
ent reason Safety thermostat activation due to an overtemperature.
Fume thermostat activation.
