Fault Cause Cure
After several lighting attempts, the elec-
tronic controller shuts down the boiler
Pilot burner nozzle dirty Clean the nozzle with compressed air
Air in gas pipes Check the regular gas flow to the boiler
and that the air has been eliminated
from the pipes
No discharge between elec-
trodes Make sure the electrodes are correctly
positioned, integral, free of any depos-
its and that the spark is regular (see
fig. 10)
Check the electrical connections at the
ignition and ionisation electrodes
Faulty gas valve Replace the valve
The boiler does not start
Electric mains trouble Make sure the boiler is connected to
the mains rated voltage and to an effi-
cient earth connection
Electric mains trouble Make sure the LINE and NEUTRAL are
not inverted and that the earth contacts
are efficient
Wiring fault Check the connections to the electronic
flame controller
No gas Check the inlet gas pressure and any
open gas pressure switches
Fume thermostat activation Reset the fume thermostat
Room thermostat open Make sure the room thermostat is
closed in call
The burner burns poorly:
flames too high, too low or too yellow
Gas pressure too low Check the gas supply pressure
Gas nozzles dirty or wrong Check the nozzles and clean if neces-
sary
Poor ventilation Make sure the ventilation in the room
where the unit is located is sufficient for
proper combustion
Smell of unburnt gas
Boiler dirty Check and clean the boiler shell
Poor flue draught Check the efficiency of the flue draught
Incorrect excess flame
adjustment Make sure the gas consumption is not
excessive (gas pressure switch nozzles
or diameter)
The boiler works but the temperature
fails to increase
Incorrect control thermostat
setting Check correct operation of the control
thermostat
Incorrect flame adjustment Make sure gas consumption is not less
than that provided for
Boiler dirty Make sure the boiler is perfectly clean
Boiler inefficient Make sure the boiler is adequate for the
system
No water circulation in the
system Make sure the heating pump is not
blocked and that the plumbing circuit is
not dirty
Temperature of water towards the sys-
tem too high
Incorrect thermostat setting Check operation of the control thermo-
stat
Incorrect thermostat posi-
tioning Check the bulb position
Explosion at burner
Ignition delays
Excess gas Check the main burner gas pressure
Boiler dirty Check and clean the boiler shell
Burner dirty Check and clean the burner
Wrong nozzles Check the nozzles
The boiler produces condensation
water
Incorrect thermostat setting Make sure the boiler is not operating at
too low temperatures (below 40°C)
Insufficient gas consumption Make sure gas consumption is regular
The boiler shuts down for no apparent
reason Fume thermostat activation Check for any obstructions in the flue
and manually reset the fume thermostat
