4. SERVICE AND MAINTENANCE

4.1 Adjustments
Gas conversion
The unit can work on natural gas or LPG and is factory-set for use with one of these two
gases, as clearly shown on the packing and data plate. Whenever a different gas to that
for which the unit is arranged has to be used, the special conversion kit will be required,
proceeding as follows:
1. Disconnect the power supply ahead of the boiler and close the gas cock;
2. Replace the nozzles at the main burner and pilot burner, fitting the nozzles indicated
in the technical data table in cap. 5, depending on the type of gas used
3. Connect the power supply ahead of the boiler and open the gas cock;
4. 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" flashing.
• press the DHW buttons (details 1 and 2 - fig. 1) to set parameter 00 (for opera-
tion with natural gas) or 01 (for operation with LPG).
• press the DHW buttons (details 1 and 2 - fig. 1) for 10 seconds.
• the boiler will return to standby mode
5. 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
6. Apply the sticker, contained in the conversion kit, near the data plate as proof of the
conversion.
TEST mode activation
Press the heating buttons (details 3 and 4 - fig. 1) 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. 17) flash on the display; the heating power will be
displayed alongside.
fig. 17 - 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 - fig. 1) togeth-
erfor 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.

Heating power adjustment
To adjust the heating power, switch the boiler to TEST mode (see sec. 4.1). Press the
heating buttons (detail 3 - fig. 1) to increase or decrease the power (min. = 00 - max. =
100). Press the reset button within 5 seconds and the max. power will remain that just
set. Exit TEST mode (see sec. 4.1).

Configuration Menu

bar
Press the DHW buttons together for 10 seconds to access the configuration Menu. 8 pa-
rameters are available, indicated by the letter "b", which are not modifiable from Remote
Timer Control.
Press the Heating buttons to scroll the list of parameters in increasing or decreasing or-
der. Press the DHW buttons to view or modify the value of a parameter: the modification
will be automatically saved.
