All burners are factory tested at 380V - 60Hz 3-phase for motors, and 220V - 60Hz single phase with
neutral for auxiliary equipments. Should it be necessary to power the burner with 220V - 60Hz,
modify the connections on motor and the terminal board as shown in the picture. Protect the burner
supply line with suitable fuses and/or other safety devices as required by the local regulations on the
