The boiler can be converted to use either methane (natural) gas (G20) or

LPG (G30 - G31) by an Authorised Service Centre.

The operations that must be performed are the following:

1. Replace the jets on the main burner (see table in section 4);

2. Adjust the maximum and minimum thermal capacity values for the boiler

(see table in section 4);

3. Replace the gas rating plate;

4. Adjust the maximum thermal power setting;

full load.

9 - Check of the heating safety systems:

- safety device for maximum temperature;

- safety device for maximum pressure.

10 - Check of the gas safety systems:

- safety device for lack of gas or flame (detection electrode);

- safety device for gas cock.

11 - Check of the electrical connection (make sure it complies with the

instructions in the manual).
