Cure
Check the regular gas flow to the
boiler and that the air has been elimi-
nated 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
terminals.
Do complete manual calibration.
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 deposits
and do a complete manual calibra-
tion, if necessary replace the elec-
trode.
Check the burner
Remove the obstruction from the flue,
fume extraction ducts, air inlet and
terminals
Check the trap and clean it if neces-
sary
Do complete manual calibration.
Check the exchanger
Check the fume probe
Check the flue material parameter
Check the correct positioning and
operation of the heating sensor and
replace it if necessary
Check the circulating pump
Vent the system
