• Adjustment of boiler minimum thermal heat
output.
- Press button (3) or (4) to select parameter b01
(minimum boiler heat output during D.H.W.).
Note:
only proceed after having calibrated the
boiler nominal heat output.
- Press the button (5) to increase the thermal
power and button (6) to decrease it. After the
adjustment, press and hold the reset button
(1) to save the parameter. Confirmation that
the parameter has been saved is given by the
value flashing.
Calibration correction.
The procedure described below allows the para-
meters set with the "Complete calibration" to
be partially changed.
Access the valve calibration function.
Note:
there must be no D.H.W. demand to access
the gas valve calibration function.
If parameter P15 has recently been set to 5
(e.g. for full gas valve calibration), a different
value must be set to access the "Calibration
correction".
• Correction of boiler nominal heat output cali-
bration.
- Press buttons (2) and (5) simultaneously for 5
seconds until ''Ma'' + "nu" (Manual) appears
alternately on the display.
Note:
press buttons (2) and (5) again for 5 se-
conds or wait 2 minutes without implementing
any adjustment to exit from the calibration
correction phase.
- Wait until the parameter b02 appears
(adjustment of the boiler nominal heat output).
Note:
the boiler starts up in heating mode; if
you wish to adjust the D.H.W., open a hot water
tap after the burner goes on.
- Adjust parameter b02, observing the maximum
pressure values stated in the tables (Paragraph
3.16) depending on the type of gas.
- Press the button (5) to increase the thermal
power and button (6) to decrease it. After the
adjustment, press and hold the reset button
(1) to save the parameter. Confirmation that
the parameter has been saved is given by the
value flashing.
• Correction of boiler minimum heat output
calibration.
- Press button (3) or (4) to select parameter b01
(minimum boiler heat output during D.H.W.).
- Press the button (5) to increase the thermal
power and button (6) to decrease it. After the
adjustment, press and hold the reset button
(1) to save the parameter. Confirmation that
the parameter has been saved is given by the
value flashing.
3.6 GAS VALVE CALIBRATION.
The valve calibration must be carried out when
the gas valve or the P.C.B. is replaced or in the
case of conversion to a different type of gas.
To access the calibration phase, proceed as
described below (references Fig. 2-1):
Complete calibration
Access the valve calibration function.
Note:
there must be no D.H.W. demand to access
the gas valve calibration function.
Set parameter P15 to 5 and exit from the menu.
• Adjustment of boiler nominal thermal heat
output
- Press buttons (2) and (5) simultaneously for 5
seconds until "Au" + "to" (Automatic) appears
alternately on the display.
Note:
press buttons (2) and (5) again for 5
seconds or wait 2 minutes without implemen-
ting any adjustment to exit from the complete
calibration phase.
- Wait until the parameter b02 appears
(adjustment of the boiler nominal heat output).
Note:
the boiler starts up in heating mode; if
you wish to adjust the D.H.W., open a hot water
tap after the burner goes on.
- Adjust parameter b02, observing the maximum
pressure values stated in the tables (Paragraph
3.16) depending on the type of gas.
- Press the button (5) to increase the thermal
power and button (6) to decrease it. After the
adjustment, press and hold the reset button
(1) to save the parameter. Confirmation that
the parameter has been saved is given by the
value flashing.
Attention:
if during the adjustment phase, the
boiler nominal heat output value is exceeded
by 0.2 mbar (table Paragraph 3.16) you must
exit and re-enter from the calibration step to
rerun the adjustment.
operations are required:
- remove the voltage from the appliance;
- replace the main burner injectors, making sure
to insert the special seal rings supplied in the
kit, between the gas manifold and the injectors;
- apply voltage to the appliance;
- select, using the boiler key, the gas parameter
type (P01) and select (
nG
) in the case of me-
thane supply or (
LG
) in the case of LPG supply;
- Perform complete gas valve calibration
• adjust the boiler nominal heat output;
• adjust the boiler nominal heat output in do-
mestic hot water phase;
- adjust the boiler nominal heat output in heating
phase (Paragraph 3.7);
- adjust (eventually) the maximum heating
power (Paragraph 3.7);
- after completing conversion, apply the sticker,
present in the conversion kit, near the data-pla-
te. Using an indelible marker pen, delete the
data relative to the old type of gas.
These adjustments must be made with reference
to the type of gas used, following that given in
the table (Paragraph 3.16).
3.5 CHECKS FOLLOWING
CONVERSION TO ANOTHER TYPE
OF GAS.
After making sure that conversion was carried
out with a nozzle of suitable diameter for the
type of gas used and the settings are made at the
correct pressure, check that:
- the pressure testers used for calibration are
perfectly closed and there are no leaks from
the gas circuit.
Note:
all boiler adjustment operations must be
carried out by a qualified company (e.g. Autho-
rised After-Sales Assistance). Burner adjustment
must be carried out using a differential "U" or
digital type pressure gauge connected to the
pressure socket located above the sealed chamber
(det. 9 Fig. 1-27) and the gas valve pressure outlet
(det. 1 Fig. 3-3), keeping to the pressure value
given in the table (Paragraph 3.16) according to
the type of gas for which the boiler is prepared.
Key:
1 - Gas valve outlet pressure point
2 - Coil
3 - Wiring connector
4 - Gas valve inlet pressure point
