3.1 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 different gas to that for which the unit is preset has to be used, a
conversion kit will be required, proceeding as follows:
1. Replace the nozzles at the main burner, inserting the nozzles specified in the technical data table in sec. 4.4, ac-
cording to the type of gas used
2. Modify the parameter for the type of gas:
• put the boiler in standby mode
• Press the RESET button (detail 6 - fig. 1) for 10 seconds: the display shows "TS" flashing
• press the RESET button (detail 6 - fig. 1): the display shows "P01".
• Press the DHW buttons fig. 1 (details 1 and 2 - ) to set parameter 00 (for operation with natural gas) or 01 (for
operation with LPG).
• Press the RESET button (detail 6 - fig. 1) for 10 seconds.
• the boiler will return to standby mode
3. Adjust the burner minimum and maximum pressures (ref. relevant paragraph), setting the values given in the tech-
nical data chart for the type of gas used
4. Apply the sticker contained in the conversion kit, near the dataplate as proof of the conversion.
