3 SERVICE AND MAINTENANCE
All adjustment, commissioning and peri-
odic checking operations described below

technician in compliance with current reg-
ulations. FERROLI declines any liability for
personal injury or damage to property due

3.1 ADJUSTMENTS
3.1.1 Gas conversion
The FERROLI KONA water heater can only work with one of the
following three gases:
- G20 (METHANE, NATURAL GAS)
- G31 (PROPANE, LPG)
- G230 (propane-air)
depending on the model purchased, as indicated on the packag-
ing and on the technical data plates.
The unit can run on NATURAL GAS (G20, G25), PROPANE AIR
(G230) or LPG (G30, G31). The unit can be adjusted to work with
a gas different from the factory-set one, by adopting the following
procedure depending on the type of gas conversion:
1 Turn off the gas valve
2 Conversion using the GAS CONVERSION KIT
(Except for the change between G30 and G31)
3 Turn on the gas valve
4 Set parameter FA (type of water heater and gas)
5 Calibrate the gas valve Except for the change be-
tween G30 and G31
6 Confirm and exit the parameters menu
