Air-gas adjustments.
The calibration of the total premix combustion system, when
necessary, envisions the adjustment of the nominal heat output
and the air-gas ratio (off-set).
The two operations are only normally requested after a gas
transformation, after extraordinary maintenance (replacement
of a component of the air-gas circuit, replacement of the integrated
P.C.B. etc.) or when the appliance is not calibrated.
N.B.: The nominal output must also be adjusted during
the initial check.
Adjustment of nominal and minimum heat
output.
The availability of maximum output is linked to the length of
the intake and exhaust pipes which, increasing, slightly reduces
the amount (flow rate) of inlet air and consequently also la
pressure of the burnt gas.
The boiler is calibrated as per standard for functioning with
a Ø60/100 horizontal concentric kit with length of 1m and
therefore the use of the flue kit with greater head losses requi-
res a check and possible adjustment of the nominal output
according to the table give below.
Below find the default settings present on the boiler (length
1 m):

The operation must be performed as follows and with respect
to the values stated in the heat output adjustment table:
- connect a differential manometer to the pressure points
P1
(positive point) and
P2
(negative point) found in the upper
part of the sealed chamber (in this way the pressure difference
at the ends of the Venturi pipes (P1-P2) is detected and a pressure
signal is measured that corresponds to the real flow rate of the
air-gas mixture at the burner).
- start the boiler in the chimney sweep phase by pressing key
"C" and then check maximum fan speed (with burner igni-
ted);
- after about 5 minutes check and, if necessary, modify the
maximum number of fan revs. in CH mode and in DHW
mode until a pressure value is obtained (P1-P2) correspon-
ding to the nominal output.
- to modify the maximum number of fan revs. enter the
"Configurations" menu and inside the “BOILER PAR."
item, modify the value of the "MAX VEL" parameter as
stated in the heat output adjustment table, until the pressure
value (P1-P2) corresponding to the maximum heat output
is obtained.
- N.B.: for the 26 kW version, the maximum number of
revs. in CH mode is lower than the absolute maximum
speed.
- to modify the maximum number of fan revs. in CH mode,
enter the "Configurations" menu and inside the "BOILER
PAR." item modify the value of the "MAX CH" parameter
as stated in the heat output adjustment table, until a pressure
value is obtained (P1-P2) that corresponds to the maximum
output in CH mode.
