2.1.3. CO2 VALUE CHECK AND
CALIBRATION
WARNING
The CO
2
value should be checked with
the casing assembled, while the gas valve should be
adjusted with the casing open.
To check and calibrate the CO2 value to minimum
and maximum heating power proceed as follows
for every single unit:
FOR MINIMUM HEATING POWER
› Activate the chimney sweep function (F07) by
holding for 7 seconds the key ‘
’ (the maximum
time of the function is 15 minutes).
› Insert the fumes analyser probe in the suitable
‘PF’ fumes inlet (fig. 1), then make sure that
the CO
2
value complies with the indications
in “Technical data”, otherwise unscrew the
protection screw ‘A’ (fig. 2) and adjust using a
4 Allen wrench the screw ‘2’ (fig. 2) of the Off-
Set adjuster. To increase the CO
2
value, turn the
screw clockwise and vice-versa if you want to
decrease it. Once completed the adjustment,
tighten the protection screw ‘A’ (fig. 2) on the
Off-Set adjuster.
FOR MAXIMUM HEATING POWER
› Press the key ‘
’ of the heating
in order to
calibrate the maximum heating power.
› Make sure that the CO
2
value complies with the
requirements indicated in chapter “Technical
data”, otherwise adjust using screw ‘1’ (fig. 2) of
the gas flow adjuster. To increase the CO
2
value,
turn the screw anti-clockwise and vice-versa if
you want to decrease it.
› After each adjustment variation on screw ‘1’
(fig. 2) of the gas flow adjuster you have to wait
for the boiler to stabilize itself to the set value
(about 30 seconds).
› Then press the key ‘
’ of the heating
and
make sure that the CO
2
value did not change
to minimum, if changed repeat the calibration
described in the previous paragraph.
› Deactivate the chimney sweep function by
switching the boiler to the ‘OFF’ operating mode
using the button ‘
’.
