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 water

– the pump impeller rotates freely
– the siphon has been filled.
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
– check that the system pressure as shown on the pressure
gauge when the system is cold , is between 1 and 1.2 bar
– press the button once for at least 1 second to select "SUMMER
mode" l . the value of the delivery sensor detected at that
moment will appear on the display
3.2.1
