WARNING
– Should it be necessary to access the areas in the
bottom part of the appliance, make sure that the
system components and pipes are not hot (risk of
burning).
– Before replenishing the heating system, put on
protective gloves.
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
– the siphon has been filled
– the flue is fitted correctly.
7.2 Before commissioning
After having carried out the preliminary operations, proceed
as follows:
– 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.
Finally
"- -"
will appear on the display
– press the button s once for at least 1 second to select
"SUMMER mode" l . The value of the delivery sensor de-
tected at that moment will appear on the display
7.2.1 Automatic self-calibrating procedure
Carry out the "Automatic self-calibrating procedure" as fol-
lows:
– turn the domestic hot water knob as far as it will go r
– press and hold down the buttons o and > at the same time
for approximately 12 seconds until the flashing symbols l
and n appear on the display
– as soon as the symbols begin to flash, release the buttons
o and > and press the button s ,
within 3 seconds
– the "Automatic self-calibrating procedure" starts
–
to dissipate the heat , tun on one or more DHW taps
– the values flash on the display:
"99"
(maximum value), fol-
lowed by an "intermediate value" and finally
"00"
(minimum
value)
It may take up 15 minutes for the "self-calibrating procedure"

CAUTION
To restore the start conditions press and hold the
button o R for more than 3 seconds. This oper-
ation can be performed up to a maximum of 6 times
without the "self-calibrating procedure" being inter-
rupted.
– press the button s once to select "WINTER mode" n . The
value of the heating water temperature detected at that mo-
ment will appear on the display
– operate the heating controls and check that the boiler starts
and operates correctly
– using the procedure shown in section "Chimney sweep
function"complete inlet working gas pressure test and a
flue gas analysis.
– record in Benchmark commissioning Check list (page 46).
