Fault A09
The boiler is equipped with an auto-diagnostic system which, based
on the total number of hours in certain operating conditions, can sig-
nal the need to clean the primary exchanger (alarm code 09 with flue
gases probe counter >2,500).
Once the cleaning operation has been completed, reset to zero the
total hour meter with special kit supplied as an accessory following
procedure indicated below:

indication.
Live electrical parts (230 Vac).
NOTE
The meter resetting procedure should be carried out after each in-
depth cleaning of the primary exchanger or if this latter is replaced.
To check the status of the totalled hours multiply the value shown by
100 (ex: shown value of 18 = pre totalled 1800 – shown value of 1=
totalled hours 100). The boiler continues to operate normally even
with the alarm active.
