and
R
on the inlet and return connections of the pump;
2
screw the rotating nut of the two flexible hoses on the pump
being careful to avoid exchanging the inlet and return lines
: see
the arrows marked on the pump that show the inlet and the return (see prevoius paragraph).

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 a jumper between terminals 6 and 7; in the event of connecting the high/low
flame thermostat remove this jumper before connecting the thermostat.
IMPORTANT: while connecting electric supply wires to burner’s teminal block be sure that ground wire should be
longer than phase and neutral ones.
WARNING: if the cable that connects the thermostats and the LME.. control box should be longer than 3 meters,
insert a sectioning relay following the attached electrical wiring diagram.
