2.4 Electrical connections
The burner is equipped with multipole sockets for the electrical connections; refer to the wiring diagram
in chapter “4 Technical Characteristics and Data” for the connections. The connections to be made by
the installer are:
• Gas pressure switch and valve connection
• supply line
• thermostat line
• possible shutdown light and/or hour counter
The length of the connection cables must allow the burner and, if necessary, the boiler door to be ope-
ned. If the burner power cable is damaged, it must only be replaced by qualified personnel.
The burner must be connected to a single-phase, 230 Volt-50 Hz electric line.
Have the efficiency and suitability of the earthing system checked by professionally qualified
personnel; the Manufacturer declines any liability for damage caused by failure to earth the
system. Also make sure the electrical system is adequate for the maximum power absorbed by
the unit, as specified on the boiler dataplate.
Make sure to respect the polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH : yellow/
green wire) when making connections to the electric line.
