Once the electrical connection of the burner is performed, remember to check the rotation of the motor. The motor should rotate accor-
ding to the arrow shown on the next picture. In the event of incorrect rotation reverse the three-phase supply and check again the rota-
tion of the motor.
NOTE:
burners are supplied for three-phase 400 V supply, and in the case of three-phase 230 V supply it is necessary to modify the
electrical connections inside the terminal box of the electric motor and replace the thermal cutout relay.
