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 CO
2
value to minimum
and maximum heating power proceed as follows:
FOR MINIMUM HEATING POWER
› Enable chimney-sweep function (F07) by
pressing ‘
’ and ‘
’ (maximum operating
time is 15 minutes), then press key ‘
’ of the
heating circuit
to set minimum power for
heating function, the display will show ‘Lo’.
› Insert the fumes analyser probe in the suitable
‘PF’ fumes inlet (fig. 1), then make sure that
the CO
2
value complies with the requirements
indicated in chapter “Technical data”, otherwise
adjust using a 40 Torx 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.
FOR MAXIMUM HEATING POWER
› Press key ‘
’ of the heating circuit
to
set maximum power for heating function, the
display will show ‘HI’.
› Make sure that the CO
2
value complies with the
indications in “Technical data”, otherwise adjust
using a 4 Allen wrench the screw ‘1’ (fig. 2) of
the gas flow adjuster. To increase the CO
2
value,
turn the screw 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 key ‘
’ of the heating circuit
and check that CO
2
value hasn’t changed, in
case it has changed, please repeat the setting
