2. PROLONGED SHUTDOWN. FROST PROTECTION
Do not drain the whole system as filling up with water again could cause unnecessary and harmful scale to build up inside the
boiler and the heating elements. If the boiler is not used during winter and is therefore exposed to the danger of frost, add some
specific anti-freeze to the water in the system (e.g.: propylene glycol coupled with corrosion and scale inhibitors). The electronic
boiler management system includes a “frost protection” function for the heating system which, when delivery temperature falls
below 5°C, lights the burner until a delivery temperature of 30°C is reached.
The function is operative if: the boiler is electrically powered, there is gas, system pressure is normal and the boiler is not
blocked.
3. GAS CONVERSION
The boilers can operate both on natural gas (G20) and LPG (G31) . All gas conversions must be made by the AUTHORISED
TECHNICAL SERVICE CENTRE.
4. FAULTS
The faults shown on the display are identified with the symbol and a number (fault code). For a com-
plete list of faults, see the following table.
If appears on the display the fault must be RESET by the user.
To RESET the boiler, press . If faults are displayed frequently, call the Authorised Service Engineer.

432
No functional hearth or safety thermostat tripped due to over
temperature (E110)
In the event of a fault, the display backlighting indicates the error code. 5 reset attempts can be performed after which the
boiler shuts down. Wait 15 minutes before attempting to reset the boiler again.
