3.5 Electrical connections
Connection to the electrical grid
The unit's electrical safety is only guaranteed when correctly connected
to an efficient earthing system executed 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 data plate.
The boiler is pre wired 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 3mm, 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.

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" 3x0.75mm2 cable with a maximum outside diameter of
8 mm.
Room thermostat (optional)(remove the existing bridge terminals 17-18)
IMPORTANT: THE ROOM THERMOSTAT MUST HAVE VOLTAGE-
FREE CONTACTS.
THERMOSTAT TERMINALS WILL PERMANENTLY DAMAGE THE
ELECTRONIC BOARD.
When connecting time controls or a timer, do not take the power supply
for these devices from their breaking contacts Their power supply must
be by means of direct connection 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 the
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. At the points of union it is recommended to check the tightness and
thermally insulate the entire duct between the boiler and chimney, in order to avoid
the formation of condensation (Non-condensing boilers).
3.7 Condensate drain connection
The unit's condensate drain must be connected to a suitable disposal system.
Comply with the specific local and national regulations on discharging condensate
water into the waste water disposal system. For boilers not using exclusively low-
sulphur gas oil (Scontent<50 ppm) make sure to provide for a suitable condensate
neutralisation device.
Connect the condensate drain pipe located at the back of the boiler (fig.25) to
the neutralisation device connected to the waste water system. The condensate
discharge pipes must be acid proof and installed sloping at least 3° towards the
drain, with-out any constrictions and obstructions.
IMPORTANT. Fill the trap with water before starting the unit.
Verify. Periodically check the water in the trap.
