BOILER COMMISSIONING
( INITIAL CHECK )
To commission the boiler:
- 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, 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 pressure gauge indicates
a pressure of 1-1.2 bar.
- switch the boiler on and check correct ignition;
- check the CO
2
flow rate in the flue:
- maximum (100%)
- intermediate (50%)
- minimum (0%)
the values must comply with what is indicated
in the relative tables (Fig. 3-14);
- check activation of the safety device in the event
of no gas, as well as the relative activation time;
- check the intervention of the main switch
located upstream of the boiler and in the boiler;
- check that the intake and/or exhaust terminals
are not blocked;
- ensure activation of all adjustment devices;
- check the production of domestic hot water;
- check sealing efficiency of water circuits;
- check ventilation and/or aeration of the instal-
lation room where provided.
If even only a single safety check offers a negative
result, do not commission the system.
