Electrical Wiring Diagram for Burners Fitted with Printed Circuit
Rotation of fan motor and pump motor
Once the electrical connection of the burner is executed, remember to check the rotation of the motor. The motor should rotate accor-
ding to the indication on the body. In the event of wrong rotation, reverse the three-phase supply and check again the rotation of the
motor.
NOTE (motors for “star/delta” start-up excluded): burners are supplied for three-phase 400V supply, and in the case of three-
phase 230V supply it is necessary to modify the electrical connections into the terminal box of the electric motor and replace
the overload tripped relay.
