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
Check the gas valve and replace it if
necessary
Check the wiring
Adjust the ignition power
Check the ionisation electrode wiring
Check the card
Check the correct positioning and
operation of the heating sensor
Vent the system
Check the thermostat
Check the wiring
Check the flue
Check the card parameter and modify
it if necessary
Check the gas pressure
Check the card parameter and modify
it if necessary
Check the wiring
Check the gas valve and replace it if
necessary
Check the wiring or replace the sen-
sor
Check the wiring or replace the sen-
