Cure
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 necessary
Do the Calibration procedure [AUTO
SETUP].
Check the gas supply pressure
Check the correct positioning and oper-
ation of the sensors and replace them if
necessary.
