6. Useful Advice
6.1 Central Heating:
• For easy operation of the boiler, a room
thermostat should be installed.
• Never shut off the radiator in the area
where the room thermostat is installed.
• If a radiator (or a convector) does not heat
up, check that no air is present in it and
that its valve is open.
• If the ambient temperature is too high, do
not alter the radiator valves. Reduce the
central heating temperature instead by
means of the room thermostat and the
knob (7 in Fig. 6.1).

6.2 Frost Protection:
• The built in antifreeze system protects the boiler from possible damages due to the freezing
temperatures.
• This system doesn’t guaranty the protection of the whole central heating system.
• In the case that the external temperature may be lower than 32 °F it is suggested to leave
the system running setting the room thermostat at a low temperature.
• When the boiler is completely switched off for a long period, it is recommended to empty
completely central heating circuit.
6.3 Periodic Maintenance:
• For efficient and continuous operation of the boiler, it is advisable to arrange maintenance
and cleaning by an Authorised Service Person, at least once a year.
• During the service, the most important components of the boiler will be inspected and
cleaned. This service can be part of a maintenance contract.
In particular, you are advised to have the following checks carried out:
• primary heat and domestic hot water exchanger;
• burner;
• exhaust fume duct and flue;
• pressurization of the expansion vessel;
• filling up of the central heating circuit;
• bleeding of air from the central heating system;
• general check of the appliance’s operation;
• check the condensate trap.
