3.1 Adjustments

Gas conversion
The unit can operate with natural gas or LPG and is factory-set for use with one of the two gases, as clearly indicated
on the packing and the dataplate. If a different gas to that for which the unit is arranged has to be used, the special
conversion kit will be required, proceeding as follows:
1. Remove the casing.
2. Open the sealed chamber.
3. Unscrew the gas fitting A located on the air/gas mixer.
4. Replace the nozzle inserted in the mixer with the one contained in the conversion kit.
5. Refit the fitting A and check the tightness of the connection.
6. Apply the sticker, contained in the conversion kit, near the dataplate.
7. Refit the sealed chamber and casing.
8. With a combustion analyser connected to the boiler fume outlet, check that the percentage of CO2 in the fumes, with
the boiler operating at maximum and minimum power, corresponds to that given in the technical data table for the
relevant type of gas.
