14.4 Troubleshooting
Fault
Two shutdown conditions resettable by the user can occur :
A Burner shutdown signalled by the special indicator. Refer to the burner manual.
B Cutting in of the safety thermostat, which occurs when the boiler temperature
reaches a value beyond which a dangerous condition may be created. To re-
store operation, unscrew cap 3 of fig. 21 and press the reset button below.
If the problem persists, request the assistance of Qualified Personnel or the After-Sales
Centre.
In case of a fault and/or poor operation, deactivate the unit, do not try to fix the problem
or directly carry out any operation. Contact authorised and professionally qualified per-
sonnel.
