3.5 Electrical connections
Connection to the electrical grid
The unit's electrical safety is only guaranteed when cor-
B
rectly connected to an efficient earthing system executed
according to current safety standards. Have the efficiency
and suitability of the earthing system checked by profes-
sionally qualified personnel. The manufacturer is not re-
sponsible for any damage caused by failure to earth the
system. Also make sure that the electrical system is ade-
quate 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 elec-
tricity 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 re-
spect 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.
The user must never change the unit's power cable. If the
B
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 diam-
eter of 8 mm.
Room thermostat (optional)
IMPORTANT: THE ROOM THERMOSTAT MUST HAVE
B
VOLTAGE-FREE CONTACTS. CONNECTING 230 V TO
THE ROOM THERMOSTAT TERMINALS WILL PERMA-
NENTLY DAMAGE THE ELECTRONIC BOARD.
When connecting time controls or a timer, do not take the
power supply for these devices from their breaking con-
tacts Their power supply must be by means of direct con-
nection from the mains or with batteries, depending on the
kind of device.
Accessing the electrical terminal block
Undo the two screws "A" located on the top part of the control panel and remove the
cover.
3.6 Connection to the flue
The unit must be connected to a flue designed and built in compliance with current reg-
ulations. 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.
4. SERVICE AND MAINTENANCE
All adjustment, conversion, commissioning and maintenance operations described be-
low must only be carried out by Qualified Personnel (meeting the professional technical
requirements of current regulations) such as the personnel of the Local After-Sales
Technical Service.
FERROLI declines any liability for damage and/or injury caused by unqualified and un-
authorised persons tampering with the unit.
