3.1 Adjustments

Gas conversion

The unit can operate on Natural Gas or LPG and is factory-set for use with one of these two gases, as clearly shown
on the packing and on the dataplate. Whenever a different gas to that for which the unit is arranged has to be used, a
conversion kit will be required, proceeding as follows:
1. Remove the casing.
2. Loosen the gas valve fixing ring "A".
3. Undo the three fixing screws "B" and remove the gas valve "C".
4. Replace the gas valve "D", positioning it inside the gasket "E", with that contained in the conversion kit. Refit the
parts and check the tightness.
5. Modify the parameter for the type of gas:
• put the boiler on standby
• press the DHW buttons (details 1 and 2 - fig. 1) at the same time for 10 seconds: the display shows "P01" flash-
ing.
• press the DHW buttons (details 1 and 2 - fig. 1) at the same time to set the parameter 00 (for natural gas) or 01
(for LPG).
• press the DHW buttons (details 1 and 2 - fig. 1) at the same time for 10 seconds.
• the boiler will go back on standby
6. Apply the label, contained in the conversion kit, near the dataplate.
7. Using a combustion analyser connected to the boiler fume outlet, make sure the CO
boiler operating at max. and min. output, matches that given in the technical data table for the corresponding type
of gas.
