COMMISSIONING

3.1

Preliminary operations

Before commissioning the appliance, check that:
– the type of gas is correct for the appliance
– the gas isolation valves for the heating system and the wa-
ter system are open
– the system pressure as shown on the pressure gauge when
the system is cold , is between 1 and 1.2 bar
– the pump impeller rotates freely.
3.2

Before commissioning

After having carried out the preliminary operations, perform
the following to start the boiler:
– set the main system switch to "ON"
ON
– the type of gas for which the boiler has been calibrated, "nG"
(methane) or "LG" (LPG,) will appear followed by the power.
After this the correct representation of the symbols will be
checked and finally "- -" will appear on the display
– press the button s once for at least 1 second to select
"SUMMER mode" . the value of the delivery sensor de-
l
tected at that moment will appear on the display

value of the heating water temperature detected at that mo-
ment will appear on the display
– adjust the air thermostat and check that the boiler starts
and operates correctly
– carry out the procedure"Chimney sweep function", to check
the mains gas pressure, detect the combustion parameters
and to measure the combustion efficiency required by legi-
slation in force..
