Cure
Check the regular gas flow to the boiler
and that the air has been eliminated
from the pipes
Check the wiring of the electrode and
that it is correctly positioned and free of
any deposits; replace the electrode if
necessary.
Check the gas supply pressure
Check the trap and clean it if neces-
sary
Remove the obstruction from the flue,
fume extraction ducts, air inlet and ter-
minals.
Do the Calibration procedure [AUTO
SETUP].
Check the gas valve and replace it if
necessary
Check the ionization electrode wiring
Check the condition of the electrode
Electrode to ground
Cable to ground
Check the trap and clean it if neces-
sary
Check the card
Check the 5-pin connector wiring
Check the fan and replace it if neces-
sary
Check the position of the ionization
electrode, free it from any encrusta-
tions and do the Calibration procedure
[AUTO SETUP]. Replace the electrode
if necessary.
Check the burner
Remove the obstruction from the flue,
fume extraction ducts, air inlet and ter-
minals
Check the trap and clean it if neces-
