BOILER COMMISSIONING
(INITIAL CHECK)
To commission the boiler:
- ensure 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 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
(Par. 3.16);
- check activation of the safety device in the event
of no gas, as well as the relative activation time;
- check activation of the master switch located
upstream from the boiler and in the boiler;
- check the existing draught during normal
functioning of the appliance, e.g. a draught
gauge positioned at the exit of the appliance
combustion products;
- check that there is no backflow of combustion
