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-
gram enclosed. To carry out the connection of the burner to the power
supply line proceed as follows:

7 and 4 pole plugs in the sockets located below the electrical panel
base as shown in figure 1.

E 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
