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"
– 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 once for at least 1 second to select "SUM-
MER mode" l . the value of the delivery sensor detected at
that moment will appear on the display

Self-calibrating procedure

Carry out the "Automatic self-calibrating procedure" as fol-
lows:
– press and hold down the buttons
for approximately 12 seconds until the flashing symbols
and n appear on the display

< and > at the same time
– as soon as the symbols begin to flash, release the buttons

– the "Automatic self-calibrating procedure" starts
– open one or more than one hot water tap
– the values flash on the display: "99" (maximum value), fol-
lowed by an "intermediate value" and finally "00" (minimum
value)
The operator must wait for approximately 15 minutes for the

has terminated:
– close the taps opened previously and check that the appli-
ance shuts down.
if there is a fault, the message "ALL" will appear on the display,

CAUTION
To restore the start conditions press and hold the
button
can be performed up to a maximum of 6 times with-
out the "self-calibrating procedure" being interrupt-
ed.
– press the button
the value of the heating water temperature detected at that
moment will appear on the display
l
– 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 leg-
islation in force..
