4. FILLING THE BOILER

Important: Regularly check that the pressure displayed by the pressure gauge is between 1 to 4 bar, with the boiler not operating.

In case the pressure is lower open the boiler filling tap.

We recommend you open the tap very slowly in order to let off the air.

In case pressure drops occur frequently have the boiler checked by a Qualified Service Engineer.

5. TURNING OFF THE BOILER

To shut down the boiler switch off the electrical supply to the appliance.

6. PROLONGED STANDSTILL OF THE SYSTEM. FROST PROTECTION

We recommend you avoid draining the whole system as raw water makeup will lead to harmful limestone deposits inside the boiler and on the heating elements.

In case the boiler is not operated during wintertime and is therefore exposed to danger of frost we suggest you add some specific-purpose anti-freeze to the water contained in the system (e.g.: propylene glycole coupled with corrosion and scaling inhibitors).

The electronic management of the boilers includes a ‘frost protection’ function which operates the burner to reach a heating flow temperature of 30° C when the system heating flow temperature drops below 5°C.

The frost protection function is enabled if:

*electrical supply to the boiler is on;

*the gas service cock is open;

*the system pressure is as required;

*the boiler is not isolated.

7. SERVICING INSTRUCTIONS AND GAS CHANGE

To maintain efficient and safe operation of your boiler have it checked by a Qualified Service Engineer at the end of every heating season. Careful servicing will ensure economical operation of the system.

Do not clean the outer casing of the appliance with abrasive, aggressive and/or easily flammable cleaners (i.e.: gasoline, alcohol, and so on). Always isolate the electrical supply to the appliance before cleaning it (see section 5 Turning off the boiler).

These boilers are produced for natural gas and can be converted to work with LPG (G 31). Any gas change must be effected by a Qualified Service Engineer.
