3 SERVICE AND MAINTENANCE
All adjustments, start-up work and regular checks described
below must be performed by an authorized technician and in
compliance with applicable regulations. FERROLI does not
accept any responsibility for personal injury or material da-
mages resulting from work on the unit by people that are not
authorized to do so.
3�1 ADJUSTMENTS
3�1�1 Gas conversion
FERROLI KONA water heater is only provided set for 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 packa-
ging and on the technical data plates.
The unit can operate with NATURAL GAS (G20, G25), with PRO-
PANE AIR (G230) or with LPG (G30, G31). The unit can be adju-
sted to work with a gas that is different to that set in the factory,
with the following steps according to the type of gas conversion:
1 - Close the gas valve
2 - Convert via the GAS TRANSFORMATION KIT
Except for changes between G30 and G31
3 - Set the FA parameter (type of water heater and gas)
4 - Open the gas valve
5 - Calibrate the gas valve
Except for changes between G30 and G31
6 - Place the new data label
1 - Close the gas valve
Before beginning any conversion:
- The gas valve must be closed.
- The water heater must then be connected to the new gas that
it is to be converted to.
2 - Convert via the GAS TRANSFORMATION KIT
The conversion for operation with a gas
that is different to that set in the factory
must be performed by an authorized
technician, using original parts and
in compliance with the applicable
regulations of the country of use.

All components damaged during the
conversion work must be replaced.
For every gas conversion in the KONA water heater, except in
the LPG model to change between G30 to G31 (from PROPA-
NE to BUTANE and vice versa, without a Kit), the appropriate
Transformation Kit must be purchased and installed, according to
the type of gas the water heater will work with, and the model in
liters of the KONA that we have:
TRANSFORMATION KIT
TO G20 GAS
- KONA 12
TO G30 / G31 GAS (LPG)
TO G25 / G230 GAS
TO G20 GAS
- KONA 15
TO G30 / G31 GAS (LPG)
- KONA 17
TO G25 / G230 GAS
The following steps apply to install the Transformation Kit:
1. Disconnect the KONA water heater from the power supply.
2. Remove the burner's collector and mount the new one accor-
ding to the instructions of the Transformation Kit provided.
3. Connect the KONA water heater to the power supply.
3 - Set the FA parameter (type of water heater and gas)
A simple setting must be made on the electronics; simply configu-
re the "FA" parameter correctly. This indicates the water heater's
model type, that is, the liters and type of gas setting:
1 Activate the parameter list by pressing the ECO key for 5 se-
conds until "PP" appears on the display. Touch the Standby
key and the first "FA" parameter appears.
2 To do this you must touch the Standby key and change the va-
lue of the current parameter with the " + " and " – " keys, accor-
ding to the water heater model and its type of gas (see Section
3.5.1 Parameter list).
3 Once configured, confirm this initial "FA" parameter with
the Standby key.
These steps always apply for the following 2 cases:
