7 commissioning
7.1
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 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.
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

) for more
than 3 seconds. this operation can be carried out no
more than 6 times.
– close the taps opened previously and check that the
appliance shuts down
– press the button
s
once to select "WiNteR mode"
n
. the
value of the heating water temperature detected at that
moment will appear on the display
– operate the heating controls and check that the boiler starts
and operates correctly
– to check that the pressure in the network and the nozzles
are correct, the procedure described in section must be
carried out "chimney sweep function".
– record in Benchmark commissioning Check list (page 39).
7.3
parameter setting and display
to go into the parameter menu:
– from the selected mode (eg. WiNteR)
– press the buttons
<
and
o

>
to scroll up the list of parameters and
then
<
to scroll down the list
note:
holding the buttons
>
or
<
increases the speed of the

– to modify the value in the permitted range, press the buttons
>
to increase it or
