boiler settings;
- check connection to a 230V-50Hz power
mains, correct L-N polarity and the earthing
connection;
- make sure the heating system is filled with
water and that the 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;
- make sure the gas maximum, medium and
minimum flow rate and pressure values
correspond to those given in the handbook
