N° 0 corresponds to the minimum speed = 960 revs). During
regulation the display shows the speed of the fan in hundreds
of revs per minute.
- to confirm the parameter set, position the main selector
switch on Reset for 2 seconds.
N.B.:
During the regulation of the minimum power, the CH
selector switch must be positioned at notch N° 5.
- after having set the minimum power, the maximum power
must be set in CH mode
by operating on the DHW regu-
lation selector switch, the travel of the power regulation in
CH mode varies from maximum to minimum. In this way,
fan speed can be regulated until a pressure value is obtained
(P1-P2) that corresponds to the nominal output in CH mode
(see heat output data). During regulation the display shows
the speed of the fan in hundreds of revs per minute.
- to confirm the parameter set, position the main selector
switch on Reset for 2 seconds.
N.B.:
During the regulation of the maximum power in CH
mode, the CH selector switch must be positioned at notch
N° 0.
Important:
The output relative to functioning in DHW
mode can be regulated up to a value equal to 26 kW, while
the functioning output in the CH phase must never exceed 24
kW (see technical data referring to the heat output).
- to confirm and memorise the settings made for each in-
dividual regulation (max. DHW, min. DHW/CH and
max. CH) always turn the main selector switch to the
Reset position for at least 2 seconds.
The boiler will go into
chimney sweep mode and at this point it is possible to verify
the calibration values with burner on or exit the chimney
sweep function, by taking the main selector switch to the
Stand-by" position .

N.B.:
If the values set are not confirmed, the calibration
values are not modified (the previous ones remain active). The
operation must be repeated from the start in order to modify
the values.
Regulation of the air-gas ratio (off-set).
The correct regulation of the air-gas ratio (1:1) takes place
in the factory and must be retouched only when carbon
dioxide (CO
2
) values are detected in the flue gases that are
not optimal.
With this scope, during the initial check or following extra-
ordinary maintenance interventions, flue analysis must be
performed at maximum heat output
and minimum heat
output
, which attests the goodness of the combustion in
reference to the values indicated in the table below:
CO

(central heating)

11,80% ± 0,2
G 31
10,60% ± 0,2
10,20% ± 0,2
Important:
the verification operations of the
CO

must be
carried out with the casing mounted, while the gas valve cali-
bration operations must be carried out with the casing open.
