3.2 INITIAL CHECK
Commissioning the appliance requires you to:
- ensure that the type of gas used corresponds to the boiler settings (the type of gas appears on the display on first electrical power supply,
on the data nameplate or by checking the relative parameter "G");
- 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;
- switch the boiler on and ensure correct ignition;
- check the proper calibration of the number of fan revolutions;
- check the CO2 flow rate in the flue:
• maximum
• intermediate
• 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 upstream of the boiler;
- check that the intake and/or exhaust terminals are not blocked;
- ensure activation of all adjustment devices;
- seal the gas flow regulation devices (if the settings are changed);
- ensure production of domestic hot water;
- check the tightness of the hydraulic circuits;
- check ventilation and/or aeration of the installation room where provided.
Even if just one single safety check provides a negative result, do not commission the system.
