Gas Connection; Electric Connection - Beretta EXCLUSIVE GREEN 25 CSI Installation And User Manual

The external diameter of the collector is 20 mm: we
therefore suggest using an Ø18-19 mm pipe, to be closed
with a suitable clamp (not supplied).
The manufacturer is not responsible for any damage
caused by the lack of a collection system.
The outlet connection line must have a guaranteed seal.
The manufacturer of the boiler is not responsible for any
flooding caused by interventions of the safety valve.

.
Before connecting appliance to gas pipe network, check
the following:
• regulations in force are met
• gas type used is the same as set for appliance operation
• pipes are clean.
Gas must be piped externally. If the pipe goes through a
wall it must go through the central opening in the lower
part of the template. It is recommended to install an
appropriately sized filter on the gas line in case gas from
the mains contains some small solid particles.
After installation make sure that all the joints have been
made airtight conforming to standard installation practices.

ELECTRIC CONNECTION

.
To access the electrical connections, proceed as follows:
- pull the cover towards you and remove (A) (fig. 6a)
- loosen the two fixing screws (C) and remove the shell
(fig. 6b)
- lift up the panel and turn it forwards
- open the terminal board covers making them slide in the
direction of the arrows (fig. 6c).
Connect the appliance to the mains power supply with a
switch featuring a distance of at least 3 mm between each
wire.
The appliance uses alternating current at 230 Volt/50 Hz,
has a power input of 130 W (16kW R.S.I. - 25kW C.S.I.)
and 175 W (35kW R.S.I. - 35kW C.S.I.), and complies
with EN 60335-1 standard.
Connect the boiler to a safe earth circuit according to
current legislation.
Live and neutral (L-N) connections should also be
respected.
The boiler can operate with phase-neutral or phase-
phase power supply. For floating power supply, without
an earth-bonded conductor, it is necessary to use an
insulation transformer with secondary anchored to ground.
The earth conductor must be a couple of cm
longer than the others.
Gas and/or water pipes may not be used to earth
electrical equipment.
The manufacturer declines liability for any
damage if the appliance was not connected to an
earth circuit.
Use the supplied power cable to connect the boiler to
the mains power supply.
Connect the ambient thermostat and/or time clock as
shown in the electrical diagram on page 95.
When replacing the power cable, use a HAR H05V2V2-
F cable, 3 x 0,75 mm 2 , Ø max. external 7 mm.
