3.1 Adjustments

Gas supply 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 different gas to that for which the unit is arranged has to be used, a
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 sec. 4.4, according
to the type of gas used
2. Modify the parameter for the type of gas:
• Switch the boiler to standby mode
• Turn the selector (detail 3 - fig. 1) to RESET for 10 seconds: the display shows "TS" flashing.
• Turn the selector (detail 3 - fig. 1) to RESET for 1 second: the display shows "P01"
• Turn the DHW knob (detail 2 - fig. 1) to set the parameter 00 (for operation with natural gas) or 01 (for operation
with LPG).
• Turn the selector (detail 3 - fig. 1) to RESET for 10 seconds
• The boiler will return to standby mode
3. Adjust the minimum and maximum pressures at the burner (refer to the relevant section), 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
Turn the selector (detail 3 - fig. 1) to the TEST position to activate TEST mode. The boiler lights up at maximum power.
The heating (detail 5 - fig. 1) and DHW symbols (detail 6 - fig. 1) flash on the display; the temperature of the heating
sensor will be displayed.
To deactivate TEST mode, turn the selector (detail 3 - fig. 1) to a different position from TEST.
In any case, the TEST mode is automatically deactivated after 15 minutes.
