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

sor
Check the wiring or replace the sen-
sor
Check the wiring or replace the sen-
sor
Check the wiring

Check the baffle and replace it if nec-
essary
Check the flue
See fault F20
Check the card parameter and modify
it if necessary
Check the card parameter and modify
it if necessary
Check the electrical system

operation of the sensors
Replace the sensor
O system circulation
Check the circulating pump
2
Vent the system
Check the wiring
Check the gas valve and replace it if
necessary
Check the flue
