2.4 Gas connection

B
The gas must be connected to the relevant connection (see cap. 2.3 "Plumbing connections") in conformity with current
standards, with a rigid metal pipe or with a continuous flexible s/steel tube, installing a gas cock between the system
and boiler Make sure all the gas connections are tight. The gas meter capacity must be suitable for the simultaneous
use of all the units connected to it. The diameter of the gas pipe leaving the boiler does not determine the diameter of
the pipe between the unit and the meter; it must be chosen according to its length and loss of pressure, in conformity
with current standards.

2.5 Electrical connections

Connection to the electrical grid
B
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.

Before making the connection, ensure that the unit is arranged for operation with the type of fuel available and
carefully clean all the gas system pipes to remove any residuals that could affect boiler operation.
Do not use the gas pipes to earth electrical appliances.
In case of connection in cascade, make sure to install a fuel shutoff valve externally with respect to the mod-
ules.
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 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.
CAUTION: The room thermostat must have clean contacts. CONNECTING 230 V. TO THE TERMINALS OF
THE ROOM THERMOSTAT WILL IRREPARABLY DAMAGE THE ELECTRONIC CARD.
When connecting a remote timer control or a timer switch, do not take the power supply for these devices from
their cut-out contacts. Their power supply must be taken with a direct connection from the mains or with bat-
teries, depending on the kind of device.
