WIRING DIAGRAM (VERSION WITH JACK)

line, outside the boiler room and in an easily accessed position. For
the electrical connections (line and thermostats), follow the wiring dia

supply line proceed as follows:
1) In the case of models with mono-phase power supply insert the two
7 and 4 pole plugs in the sockets located below the electrical panel
base as shown in figure 1.
2) In the case of models with three-phase power supply, unscrew the
2 screws (1) and pull back lightly the cover to detach it from the electri

cal panel base (see figure 2). Lift up the cover to reach the electrical
components.
3) Connect the power supply cables (2) to the contactor, fix the ground
cable (3) and tighten the cable holder (see figure 3). Connect the two
7 and 4 pole plugs.
4) Re-close the lid taking care to position the two hooks (4) correctly
in their right position (see figure 4).
Important: only qualified technicians may open the burner’s electrical
