3 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
system are open
– 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
Fig. 33
– 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 Y 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 Self-calibrating procedure
Carry out the "Automatic self-calibrating procedure" as follows:
– press button r and set the DOMESTIC HOT WATER SET to
maximum using the button >
– press and hold down the buttons < and > at the same time for
approximately 10 seconds until the flashing symbols l and
n appear on the display
– as soon as the symbols begin to flash, release the buttons <
and > and press the button y , within 3 seconds
– the "Automatic self-calibrating procedure" starts
–
open one or more than one hot water tap
– the values flash on the display:
"100"
(maximum value),
followed by an "intermediate value" and finally "00" (minimum
value)
The operator must wait for approximately 15 minutes for the
"self-calibrating procedure" to end and the message "SUMMER

"WINTER mode" n . The value of the heating water
temperature detected at that moment will appear on the
display
– adjust the air thermostat and check that the boiler starts and
operates correctly
– carry out the procedure "Chimney sweeper function",
to check the mains gas pressure, detect the combustion
parameters and to measure the combustion efficiency
required by legislation in force.
