SINGLE SPLITTING KIT
(ALTERNATIVE ACCESSORY)
For special installations of the fumes inlet/outlet ducts, the
single splitting kit (
C
), supplied as an accessory, can be
used. This accessory, in fact, can be used to move the inlet
and outlet in any direction. This type of installation makes
it possible to discharge exhaust fumes both outside the
building and into single flue ducts. Comburent air can be
drawn in at a different location from that of the flue terminal.
The splitting kit is fixed to the boiler turret (100/60 mm) and
allows the comburent air and outlet fumes to enter/leave the
two separate ducts (80 mm). For further information, read the
assembly instructions supplied with the accessory.
SOME OUTLET DUCT INSTALLATION EXAMPLES AND THEIR RELATIVE MAXIMUM LENGTHS ARE SHOWN IN ANNEX

11. ELECTRICAL CONNECTIONS
This machine is only electrically safe if it is correctly connected to an efficient earth system in compliance with current safety
regulations. Connect the boiler to a 230V single-phase earthed power supply using the supplied three-pin cable, observing correct
Live-Neutral polarity.
Use a double-pole switch with a contact separation of at least 3 mm.
When replacing the power supply cable, fit a harmonised “HAR H05 VV-F” 3x0,75 mm
2
cable with a maximum diameter of 8 mm.
To access the terminal block, remove the front boiler panel (fixed with two screws at the bottom), turn the control box downwards
and access terminal blocks
M1, M2, M3
, used for the electrical connections, after removing the protective cover. The 3.15 A fast-
blowing fuses are incorporated in the power supply terminal block (to check and/or replace the fuse, pull out the black fuse carrier).

Make sure that the overall rated power input of the accessories connected to the appliance is less than 2A. If it is higher, install
a relay between the accessories and the electronic board.
The connections in terminal blocks M1- M3 are high voltage (230 V). Before making connections, make sure the appliance is
disconnected from the power supply. Respect the input polarity on terminal block M1: L (LINE) - N (NEUTRAL).

Put back the jumper on terminals 1-2 of boiler terminal
block M1 if the room thermostat is not used or if the
Remote Control, supplied as an accessory, is not
installed.
TERMINAL BLOCK M2
Terminals 1 - 2:
connection to the Remote Control (low
voltage) supplied as an accessory.
Terminals 4 - 5 (common):
external Probe connection (supplied as an accessory)
Terminals 3-6-7-8:
not used.
Terminals 9-10:
storage boiler sensor connection.
If the appliance is connected to an underfloor system, install a limit thermostat to prevent the latter from overheating.
Use the relative cable grommets at the bottom of the boiler to thread the cables through to the terminal blocks.
