BOILER START-UP (INI-
TIAL 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 pressure gauge 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 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 set-
tings are modified);
- 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.
