3.4 Gas connection

B
Before carrying out the connection, make sure the unit is arranged for operation
with the type of fuel available and carefully clean all the pipes of the gas system
to remove any residues that could affect proper boiler operation.
The gas must be connected to the relevantfig. 42connection (see ) in conformity with the
current standards, with a rigid metal pipe or with a continuous surface flexible s/steel
tube, installing a gas cock between the system and boiler. Make sure all the gas connec-
tions 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 deter-
mine the diameter of the pipe between the unit and the meter; it must be chosen accord-
ing to its length and pressure losses, in conformity with the current standards.
B
Do not use the gas pipes to earth electrical appliances.
In case of connection in cascade, make sure to install a fuel shutoff valve ex-
ternally with respect to the modules.

3.5 Electrical connections

Connection to the electrical grid
B
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 dataplate.
306
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
D
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 person-
nel. If changing the electric power cable, use solely "HAR H05 VV-F" 3x0.75
mm2 cable with a maximum outside diameter of 8 mm.
Room thermostat (optional)
B
CAUTION: The room thermostat must have clean contacts. CONNECTING
230 V. TO THE TERMINALS OF THE ROOM THERMOSTAT WILL IRREPA-
RABLY DAMAGE THE ELECTRONIC CARD.
When connecting a remote timer control or a timer switch, do not take the pow-
er supply for these devices from their cut-out contacts. Their power supply must
be taken with a direct connection from the mains or with batteries, depending
on the kind of device.
