Connection to the electrical grid

B

The unit's electrical safety is only guaranteed when correctly connected to an efficient earthing system exe-
cuted according to current safety standards. Have the efficiency and suitability of the earthing system checked
by professionally qualified personnel. The manufacturer is not responsible for any damage caused by failure
to earth the system. Also make sure that the electrical system is adequate for the maximum power absorbed
by the unit, as specified on the boiler dataplate.

The boiler is prewired and provided with a Y-cable and plug for connection to the electricity line. The connections to the
grid must be made with a permanent connection and equipped with a bipolar switch whose contacts have a minimum
opening of at least 3 mm, interposing fuses of max. 3A between the boiler and the line. It is important to respect the
polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH:  yellow-green wire) in making connections to the electrical
line. During installation or when changing the power cable, the earth wire must be left 2 cm longer than the others.

B

The user must never change the unit's power cable. If the cable gets damaged, switch off the unit and have it
changed solely by professionally qualified personnel. If changing the electric power cable, use solely 

“HAR

H05 VV-F”

 3x0.75 mm2 cable with a maximum outside diameter of 8 mm.

2.6 Connection to the flue

The unit must be connected to a flue designed and built in compliance with current regulations. The pipe between the
boiler and flue must be made from material suitable for the purpose, i.e. heat and corrosion resistant. Ensure the seal
at the joints and insulate the entire pipe between boiler and flue, to prevent the formation of condensate.
