10. TROUBLESHOOTING
Do not drain the whole system as filling up with water again causes 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, operates the burner until a delivery temperature of 30°C is reached.
The frost protection function is enabled if:
* the boiler is electrically powered;
* the gas tap is open;
* the system is at the correct pressure;
* the boiler is not blocked.
9. PROLONGED SHUTDOWN. FROST PROTECTION
To RESET the boiler, press and hold down “R” for at
least 2 seconds. If this fault persists, call the Authorised
Service Centre.
N.B.:
5 reset attempts can be performed after which
the boiler shuts down. To reset again, switch off the
boiler for a few seconds.

To keep the boiler efficient and safe, have it checked by the authorised Service Centre at the end of every operating period.
Careful servicing ensures economical operation of the system.
Do not clean the outer casing of the appliance with abrasive, aggressive and/or easily flammable cleaners (e.g.: petrol,
alcohol, and so on). Always switch off the appliance before cleaning it (see section 7 “Switching off the boiler”).
