Electrical connections
To connect the burner, please refer to the wiring diagram.
To execute the electrical connections, proceed as follows:
1 remove the cover from the electrical board, unscrewing the fixing screws;
2 execute the electrical connections to the supply terminal board as shown in the attached wiring diagrams,
3 check the direction of the fan motor and pump motor (see next pargraph)
4 refit the panel cover
Rotation of fan motor and pump motor
Once the burner’s electrical connection is accomplished, remember to check the rotation of the fan and pump motors. The motor
should rotate in counterclockwise direction looking at motor’s cooling fan. In case of incorrect rotation, reverse the three-phase supply
and check again the rotation of the motor.

PLEASE READ CAREFULLY THE “WARNINGS” CHAPTER AT THE BEGINNING OF THIS MANUAL.
Respect the basic safety rules. make sure of the connection to the earthing system. do not reverse the phase and
neutral connections. fit a differential thermal magnet switch adequate for connection to the mains.
ATTENTION: before executing the electrical connections, pay attention to turn the plant’s switch to OFF and be
sure that the burner’s main switch is in 0 position (OFF) too. Read carefully the chapter “WARNINGS”, and the
“Electrical connections” section.
WARNING: The burner is provided with an electrical bridge between terminals 6 and 7; when connecting the high/
low flame thermostat, remove this bridge before connecting the thermostat.
IMPORTANT: Connecting electrical supply wires to the burner teminal block MA, be sure that the ground wire is
longer than phase and neutral ones.
CAUTION: adjust the thermal cut-out according to the motor rated current value.
