2.1.3. CO2 VALUE CHECK AND
CALIBRATION
WARNING
The CO
2
value should be measured with
the casing assembled, while the gas valve could
only be adjusted with the casing open.
To check and calibrate the CO
2
value to minimum
and maximum power proceed as follows:
FOR MINIMUM POWER
› Access parameter ‘P06’ following the procedure
described in 2.1.4 “Parameters accessing and
programming” and stay in edit mode until the
calibration is completed (the maximum time
before forced to exit the edit mode is 7 minutes.
› Insert the combustion analyser probe in the
suitable ‘PF’ exhaust tap (fig. 23), then make
sure that the CO
2
value complies with the
indications in 2.2.8 “Technical data”, otherwise
unscrew the protection screw ‘A’ (fig. 24) and
adjust using a 4 Allen wrench the screw ‘2’ (fig.
24) of the Off-Set adjuster. To increase the CO
2
value, turn the screw counter-clockwise and
clockwise if you want to decrease it.
› Once the adjustment has been completed,
tighten the protection screw ‘A’ (fig. 24) on the
Off-Set adjuster.
› Exit parameter ‘P06’ following the procedure
described in 2.1.4 “Parameters accessing and
programming”.
FOR MAXIMUM POWER
› Open several D.H.W. taps at the highest flow
rate.
› Access parameter ‘P07’ following the procedure
described in 2.1.4 “Parameters accessing and
programming” and stay in edit mode.
› Insert the combustion analyser probe in the
suitable ‘PF’ exhaust tap (fig. 23), then make
sure that the CO
2
value complies with the
requirements indicated in 2.2.8 “Technical data”,
otherwise adjust using screw ‘1’ (fig. 24) of the
gas flow adjuster. To increase the CO
2
value, turn
the screw counter-clockwise and clockwise if
you want to decrease it.
› After each adjustment variation on screw ‘1’
(fig. 24) of the gas flow adjuster you have to wait
for the water heater to stabilize itself to the set
value (about 30 seconds).
› Enter again the parameter P06 and make sure
that the CO
2
value did not change to maximum, if
changed repeat the calibration described in the
previous paragraph.
