CONVERTING THE APPLIANCE TO OTHER TYPES OF GAS
The gas conversion operation must be carried out by an authorised company (e.g. Authorised Technical Assistance Service).
If the appliance needs to be converted to a different gas type to that specified on the data plate, request the relative conversion kit for quick
and easy conversion.
To convert to another type of gas the following operations are required:
- Disconnect power to the appliance;
- Replace the nozzle positioned above the gas valve (Part. 8, Fig. 51) taking care to disconnect the appliance during this operation;
- Re-power the appliance;
- Calibrate fan speed (Par. 3.8);
- Adjust CO
/O
(Parag. 3.9);

- Seal the gas flow rate regulation devices (if settings are modified);
- After completing the conversion, apply the sticker, contained in the conversion kit, on the data plate in the area relating to the type of
gas. Using an indelible marker pen, delete the data relative to the old type of gas.
These adjustments must be made with reference to the type of gas used, following that given in the table (Parag. 4.2).
