3.2 INITIAL CHECK.
To commission the boiler:
- ensure that the declaration of conformity of instal-
lation is supplied with the appliance;
- make sure that the type of gas used corresponds to
boiler settings (the type of gas is displayed on the
data nameplate and in the relevant P01 parameter);
- check connection to a 230V ~ 50Hz power mains, correct
L-N polarity and the earthing connection;
- make sure the central heating system is filled with water and
that the boiler manometer indicates a pressure of 1÷1.2 bar;
- make sure the air valve cap is open and that the system is well
deaerated;
- switch the boiler on and ensure correct ignition;
- check the CO flow rate in the flue:
2
• maximum;
• minimum;
- the values comply with the relevant tables (Par. 3.3);
- check activation of the safety device in the event of no gas, as
well as the relative activation time;
- check activation of the main switch located outside the boiler;
- check that the intake and/or exhaust terminals are not
blocked;
- check activation of the "no air" safety pressure switch;
- ensure activation of all adjustment devices;
- seal the gas flow regulation devices (if the settings are
changed);
- ensure production of domestic hot water (when the boiler is

where provided.
Even if just one single safety check provides a negative result,
do not commission the system.
