Cure
Check the position of the ionization elec-
trode, free it from any deposits and do a
complete manual calibration, if necessary
replace the electrode.
Check the burner
Remove the obstruction from the flue, fume
extraction ducts, air inlet and terminals
Check the trap and clean it if necessary
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
Check the circulating pump and heating
system
Vent the system
check the exchanger and system
