2.4 Gas connection

Before making the connections, check that the appliance is configured for operation with the
type of fuel available, and carefully clean all the gas pipes in the system, to remove any residues
that may affect the correct operation of the boiler.
The gas connections must be made using the relative coupling (see fig. 4), according to the standards
in force, with a rigid metal pipe, fitting a gas cock between the system and the boiler. Check that all the
gas connections for soundness.
The capacity of the gas meter must be sufficient for the simultaneous use of all the connected appliances.
The diameter of the gas pipe, which leaves the boiler, does not necessarily determine the choice of the
diameter of the pipe used between the appliance and the gas meter; this must be chosen according to
its length and the pressure drop, according to the standards in force.
Do not use the gas pipes as the earth for electrical appliances.

2.5 Electrical connections

Connection to the mains power supply
The boiler should be connected to a single-phase, 230 Volt-50 Hz electrical power supply.
The electrical safety of the appliance is ensured only when the appliance is correctly connected
to an effective earth system, as prescribed by the safety standards in force. Have professionally
qualified personnel check the efficiency and the rating of the earth system. The manufacturer
is not liable for any damage caused by the appliance not being correctly earthed. In addition,
make sure that the electrical system is adequately rated for the maximum power absorbed by
the appliance, indicated on the boiler rating plate, and in particular that the cross-section of the
wires is suitable for the power absorbed by the appliance.
The boiler is pre-wired and fitted with a cable for connection to the electrical line. The connections to
the mains supply must be made using a fixed connection, featuring a double-pole switch with a contact
opening of at least 3 mm. Max 3A fuses must be installed between the boiler and the line. The correct
polarity must be followed (LINE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green wire) in the
electrical connections.
The appliance's power cable must not be replaced by the user. In the event where the cable is
damaged, turn off the appliance and contact professionally qualified personnel to replace it. If
replacing the electrical power cable.
All wiring must conform to current I.E.E. Regulations
Accessing the electrical terminal block
Follow the operation shown in Figs. 6a and 6b to access the electrical terminal block. The layout of
the terminals for the various connections is shown in the wiring diagram, in the chapter on Technical
Specifications.
