Table. 7 - Typology
If the boiler is to be connected

to a collective flue or a single flue with
natural draught, the flue or chimney must be expressly designed by professionally qual-
ified technical personnel in conformity with the current regulations and be suitable for
sealed chamber units equipped with fan.
4. SERVICE AND MAINTENANCE
4.1 Adjustments
Gas conversion
The unit can operate on natural gas or LPG and is factory-set for use with one of these
two gases, as clearly shown on the packing and on the dataplate. Whenever a gas dif-
ferent from that for which the unit is arranged has to be used, the special conversion kit
will be required, proceeding as follows:
1.
Replace the nozzles at the main burner, fitting the nozzles specified in the technical
data table in cap. 5, according to the type of gas used
2.
Modify the parameter for the type of gas:
•
put the boiler in standby mode
•
press the DHW buttons details 1 and 2 - fig. 1 for 10 seconds: the display shows
“
b01
“ blinking.
•
Press the DHW buttons fig. 1 (details 1 and 2 -
) to set parameter 00
(for nat-
ural gas operation) or
01
(for LPG operation).
•
press the DHW buttons details 1 and 2 - fig. 1 for 10 seconds.
•
the boiler will return to standby mode
3.
Adjust the minimum and maximum pressures at the burner (ref. relevant para-
graph), setting the values given in the technical data table for the type of gas used
4.
Apply the sticker contained in the conversion kit, near the dataplate as proof of the
conversion.
TEST mode activation
Press the heating buttons (details 3fig. 1and 4 - ) together for 5 seconds to activate the
TEST
mode. The boiler lights at the maximum heating power set as described in the fol-
lowing section.
The heating and DHW symbols (fig. 14) flash on the display; the heating power will be
displayed alongside.
fig. 14 - TEST mode (heating power = 100%)
Press the heating buttons (details 3 and 4 - fig. 1) to increase or decrease the power
(min.=0%, max.=100%).
Press the DHW button
"-"
(detail 1 - fig. 1) and the boiler power is immediately adjusted
to min. (0%). Press the DHW button
"+"
(detail 2 - fig. 1) and the boiler power is imme-
diately adjusted to max. (100%).
To deactivate the TEST mode, press the heating buttons (details 3 and 4 - )
togetherfig. 1for 5 seconds.
The TEST mode is automatically disabled in any case after 15 minutes.
Pressure adjustment at the burner
Since this unit has flame modulation, there are two fixed pressure settings: minimum and
maximum, which must be those given in the technical data table according to the type of
gas.
•
Connect a suitable pressure gauge to the pressure point
"B"
downstream of the
gas valve.
•
Activate the TEST mode (see cap. 4.1).
•
Press the Eco/Comfort button for 2 seconds to access the gas valve Calibration
mode.
•
The card goes to the setting “q02”; displaying the actually saved value, by pressing
the DHW buttons .
•
If the pressure gauge reading is different from the nominal maximum pressure, pro-
ceed by increases/decreases of 1 or 2 units of parameter “q02” by pressing the
DHW buttons : the value is stored after each modification; wait 10 seconds for the
pressure to stabilise.
•
Press the heating button “-” (ref. 3 - fig. 1).
•
The card goes to the setting “q01”; displaying the actually saved value, by pressing
the DHW buttons .
•
If the pressure gauge reading is different from the nominal minimum pressure, pro-
ceed by increases/decreases of 1 or 2 units of parameter “q01” by pressing the
DHW buttons : the value is stored after each modification; wait 10 seconds for the
pressure to stabilise.
•
Recheck both adjustments by pressing the heating buttons and adjust them if nec-
essary by repeating the above procedure.
•
Press the Eco/Comfort button for 2 seconds to return to the TEST mode.
•
Deactivate the TEST mode (see cap. 4.1).
•
Disconnect the pressure gauge.
