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.
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).
- enter the calibration function by positioning the DHW regu-
lation selector switch on notch N° 6 and the CH regulation
selector switch on notch N° 9.
- turn the main selector switch to the Reset position for 15
seconds and then release it when "Id" (identification) appears
on the boiler display.
- once the calibration menu has been entered, the display
will show the DHW symbol and the flame with flashing
maximum power scale.
N.B.:
If identification does not take place within 15 secon-
ds, the boiler will go into Stand-by and the error code E08
equivalent to "Reset selector switch fault" will be displayed.
To restore the appliance, turn the main selector switch to the
(Stand-by) . position.
- at this point the maximum power can be changed in DHW
mode
by operating on the DHW regulation selector switch
regulating the fan speed until the pressure value is obtained
(P1-P2), which corresponds to the nominal output (notch
N° 9 corresponds to the maximum speed= 6000 revs, notch
N° 0 corresponds to the minimum speed = 4500 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 maximum power in DHW
mode, the CH selector switch must be positioned at notch
N° 9.
- after having set the maximum power in DHW mode, the
minimum power can be set (DHW and CH
) by operating
on the DHW regulation selector switch adjusting the fan
speed from 960 to 1200 revs until obtaining a pressure
value (P1-P2) corresponding to the minimum power (notch
N° 9 corresponds to the maximum speed = = 1200 revs, notch
