POSSIBLE REASON
• The electronic board has been
replaced and not yet calibrated
for the boiler model.
• Parameters F03 and F12 have
not been set or have been
incorrectly set.
• No inlet gas pressure.
• Gas valve modulator wires not
connected.
• Flame sensing electrode faulty or
incorrectly positioned.
• Air-flue duct partially obstructed.
• Gas valve faulty.
• Electronic board faulty.

SERVICE ACTION
• Set parameters F03 and F12 with the values indicated
in the table in the SETTING PARAMETERS section
according to the boiler model indicated on the rating
plate.
• Check the gas supply pressure
• (for natural gas Palim.>9mbar).
• Check the connection of the gas valve modulator
wiring to the electronic board.
• Check that the pressure at the burner has been
correctly calibrated (see the GAS VALVE section)
• Check the flame sensing electrode is in good
condition and correctly positioned (see the
POSITIONING THE IGNITION AND FLAME-
SENSING ELECTRODE section).
• Make sure the air and flue ducts are not obstructed
and have been correctly installed (they must not
exceed the prescribed maximum lengths and must
be fitted with the correct diaphragm – see the
INSTALLING THE DUCTS section).
