- Remove the analyser probe and close the combustion analysis
socket with the screw.
- Install the panel by following the instructions in paragraph "Com-
bustion check".

4.12 Gas conversion

Conversion from a family gas to other family gas can be performed
easily also when the boiler is installed.
This operation must be carried out by professionally qualified per-
sonnel.
The boiler is designed to operate with methane gas (G20) according
to the product label.
It is possible to convert the boiler to propane gas (G31) using the
special accessory kit supplied.
For disassembly, refer to the instructions provided below (fig. 46):
- disconnect the boiler from the electricity supply and turn off the
gas tap
- remove in the following order: air distribution box cover and casing
- disconnect and turn the instrument panel forward
- remove the gas train (A)
- remove the nozzle (B) contained within the gas train and replace it
with the one contained in the kit
- replace the gas train (make sure that the gas train connected to the
mixer of the fan is in position)
- reassemble the air distribution box cover, power-up the boiler and
open the gas tap.
Adjust the boiler as described in chapter "Settings" referring to the
data concerning the gas in question (G31).
Conversion must be carried out by qualified personnel.
After the gas transformation, apply the new rating plate includ-
ed in the kit.

- If the reading is different, modify as indicated in chapter "Settings".
- Perform the combustion check.
- Exit this function by turning the extension under the knob (1a, fig.
47) to (winter) or (summer), then position it back on
