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 power proceed as follows:
FOR MINIMUM POWER
› Access parameter ‘P06’ following the procedure
described in chapter “ACCESSING AND
PROGRAMMING THE PARAMETERS” and stay
in edit mode until the calibration is completed
(the maximum time before forced exiting the
edit mode is 7 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 requirements
indicated in chapter “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.
› Exit parameter ‘P06’ following the procedure
described in chapter “ACCESSING AND
PROGRAMMING THE PARAMETERS”.
FOR MAXIMUM POWER
› Open several D.H.W. taps at the highest flow
rate.
› Access parameter ‘P07’ following the procedure
described in chapter “ACCESSING AND
PROGRAMMING THE PARAMETERS” and stay
in edit mode until the calibration is completed
(the maximum time before forced exiting the
edit mode is 7 minutes).
› Then make sure that the CO
2
value complies with
the indications in “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 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 minimum, if
changed repeat the calibration described in the
previous paragraph.
