3.1 Adjustments

3.1.1 Gas conversion

Conversion for operation with a
gas different from that arranged
in the factory must be carried
out by an authorised technician,
using original parts and in com-
pliance with the regulations in
force in the country where the
unit is installed.
All components damaged du-
ring conversion
must be replaced.
The unit can run on Natural Gas, LPG and Propane-
Air and is factory-set for Natural Gas or LPG, as clearly
shown on the packaging and on the data plate. Whene-
ver a gas different from that for which the unit is arranged
has to be used, the special conversion kit will be requi-
red, proceeding as follows:

1. Change the parameter for the type of gas:
• Put the water heater in standby mode (detail 1 - fig.
3).
• Press the On/Off button (detail 1.2 - fig. 1) for 25
seconds: the display shows "b" alternating with
"01".
• Press the DHW "+" or "-" buttons to access the pa-
• To set parameter 00 (for natural gas operation) or
• Once the value has been changed, keep the On/
2. Disconnect the water heater power supply and turn
off the gas cock.
3. Replace the nozzles at the main burner, fitting those
indicated in the technical data table in chap. 4.4, ac-
cording to the type of gas used.
4. Switch on the power to the water heater and turn on
the gas cock.
operations
5. Adjust the minimum and maximum pressures at the
burner (see relevant paragraph ), setting the values
indicated in the technical data table for the type of
gas used
6. Apply near the data plate the sticker contained in the
conversion kit, as proof of the conversion.

2. Activate the calibration procedure by pressing the
DHW "+" button and "On/Off" button together for 5
seconds. The message "Au" appears alternating with
"to" and the burner is lit. Within 8 seconds the water
heater finds the ignition point. The values of ignition
point, absolute minimum current Offset (parameter
q01) and absolute maximum current Offset (value
q02), are stored by the card.
