  BOILER START-UP 

(INITIAL CHECK).

To commission the boiler:

- make sure that the declaration of conformity 

for installation is supplied with the appliance;

- make sure that the type of gas used corresponds 

to boiler settings;

- 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 manometer indicates 

a pressure of 1÷1.2 bar;

- check that the heat pump is connected and 

powered properly (see relative instructions 

manual);

- check that the common parameters between 

the heat pump and the boiler are configured 

properly;

- switch the boiler on and check correct ignition;
- check the ∆p gas values in domestic hot water 

and central heating modes;

- check the CO

2

 in the fumes at maximum and 

minimum flow rate;

- 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;
- seal the gas flow rate regulation devices (if 

settings are modified);

- check the production of domestic hot water;
- check sealing efficiency of water circuits;
- check  ventilation  and/or  aeration  of  the 

installation room where provided.

If even only a single safety check offers a negative 

result, do not commission the system.
