Fume recuperator cleaning
To clean the recuperator:
•
Lift the boiler top panel A and remove back panel B .
• Remover fume recuperator closing cover C .
• Using a suitable tube-brush and a vacuum cleaner, thoroughly clean the inside of
the recuperator.
• If very dirty, a suitable device for spraying water inside can be used. In this case,
make sure large amounts of water do not come into contact wit the cast iron ele-
ments in the smoke chamber. Run the water through condensate drain
D after dis-
connecting the trap.

4.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault,
the display will flash together with the fault symbol (detail 22 - fig. 118) indicating the fault
code.
There are faults that cause permanent shutdown (marked with the letter "
A "): to restore
operation, press the RESET button (detail 8 - fig. 118) for 1 second or RESET on the op-
tional remote timer control if installed; if the boiler fails to restart, it is necessary to elim-
inate the fault indicated by the operation LEDs.
Faults marked with the letter "
F " cause temporary shutdowns that are automatically reset
as soon as the value returns within the boiler's normal working range.
