Set the summer/winter switch to winter. Check that gas pressure to the burner matches that stated in the table
(maximum value). If not, remove the cap from the pressure regulator and adjust pressure to the indicated
value. Screw the cap again and seal it.
Warning: pressure can be adjusted to any of the values indicated in the table. In this case, hot water supply
decreases accordingly.
Shut off the burner turning the main switch. Wait for at least 30 seconds. Ignite the burner again and check for
slow ignition (approx. values: 8 mbars). Disconnect the manometer and tighten the downstream pressure point
screw.

Conversion from Methane to LPG
- Replace the burner jets
- Exclude the pressure reducer tightening screw 2 and then screw 1.
- Check pressure upstream, measuring it on the pressure point of the gas delivery pipe and adjust the plant
pressure regulators so as to have the pressure indicated in the technical data table (page 26).
- Check that pressure to the burner matches that indicated in the technical data table (page 26)
- Seal screws 1 and 2
- Stick the label “Boiler adjusted for LPG” on the existing one
