1 WARNINGS AND SAFETY
b
The boilers manufactured in our factories are checked even in
the smallest details in order to protect users and installers against
possible injury. After working on the product, qualified personnel
must check the electrical wiring, in particular the stripped part of
leads, which must not protrude from the terminal board and avoiding
possible contact with live parts of the leads themselves.
b
This installer and user manual constitutes an integral part of the
product: make sure they are always kept with the appliance, even
if it is transferred to another owner or user, or moved to another
heating system. In case of loss or damage, please contact your local
Technical Assistance Service for a new copy
.
b
This boiler may only be installed and serviced by personnel qualified
in accordance with current regulations.
b
The installer must instruct the user about the operation of the appli-
ance and about essential safety regulations.
b
This boiler must only be used for the application it was designed for.
The manufacturer accepts no liability within or without the contract
for any damage caused to people, animals and property due to in-
stallation, adjustment and maintenance errors or to improper use.
b
This appliance should not be operated by children younger than 8
years, people with reduced physical, sensory or mental capacities,
or inexperienced people who are not familiar with the product, unless
they are given close supervision or instructions on how to use it sa-
fely and are made aware by a responsible person of the dangers its
use might entail. Children must not play with the appliance. It is the
user’s responsibility to clean and maintain the appliance. Children
should never clean or maintain it unless they are given supervision.
b
After removing the packaging, make sure the content is in good con
-
dition and complete. Otherwise, contact the dealer from whom you
purchased the appliance.
b
The safety valve outlet must be connected to a suitable collection
and venting system. The manufacturer declines all liability for any
damage caused due to any intervention carried out in the safety
valve.
b
The seal of the condensate drainage connection line must be secure,
and the line must be fully protected against the risk of freezing (e.g.
by insulating it).
b
Check that the rain water drainage channel of the flue gases fitting
and the relative connection pipe are free of obstructions.
b
Dispose of all the packaging materials in the suitable containers at
the corresponding collection centres.
b
Dispose of waste by being careful not to harm human health and
without employing procedures or methods which may damage the
environment.
b
At the end of its life, the product should be not be disposed of as solid
urban waste, but rather it should be handed over to a differentiated
waste collection centre.
b
During installation, inform the user that:
-
in the event of water leaks, the water supply must be shut off and
the Technical Assistance Centre must be contacted immediately
-periodically check that the operating pressure of the hydraulic
system is comprised between 1 and 1.5 bar. If it is not, request
the prompt intervention of the Technical Assistance Centre or else
professionally qualified personnel
.
b
If the boiler is not used for a long period of time, it is recommended
to perform the following operations:
-
turn the main appliance switch and the main system switch to “off”
-close the fuel and water valves for the heating and domestic hot
water system
-empty the heating and domestic hot water circuits if there is the
risk of freezing
b
Boiler maintenance must be carried out at least once a year; this
should be booked in advance with the Technical Assistance Centre
to ensure the necessary safety standards.
At the end of its life, the product should be not be disposed of as solid
urban waste, but rather it should be handed over to a differentiated
waste collection centre.
For safety reasons, please remember that:
a
It is forbidden to touch the appliance while barefoot or if parts of your
body are wet.

a
It is forbidden to activate electric devices or appliances such as
switches, household appliances and so on if you notice a smell of
fuel or unburned fuel. In this case:
-ventilate the room by opening the doors and windows;
-c
lose the fuel shut-off device
;
-
request the prompt intervention of the Technical Assistance Centre
or else professionally qualified personnel
.
a
Any technical or cleaning operation is forbidden before disconnecting
the appliance from the main power supply by turning the system’s
main switch to “OFF” and the main switch of the boiler to “OFF”.
a
Do not modify the safety or adjustment devices without the
manufacturer’s authorisation and precise instructions.
a
It is prohibited to pull, detach or twist the electrical cables coming
from the appliance even if it is disconnected from the mains power
supply.
a
Avoid blocking or reducing the size of the air vent openings in the
installation room.
a
Do not leave flammable containers and substances in the room
where the device is installed.
a
It is forbidden to disperse the packaging material in the environment
and leave it within children’s reach as it may be a potential source
of danger. It must be disposed in accordance with the present law.
a
The condensate drain outlet must be turned towards the drain outlet
avoiding the formation of more siphons.
a
Never carry out any work on the gas valve.
a
Only for the user:
Do not access the inside of the boiler. Any work on
the boiler should be carried out by the Technical Assistance Centre or
by professionally qualified personnel.

DESCRIPTION
EXCLUSIVE
boilers have a new ACC (Activate Combustion Control)
system. This new control system, developed by Beretta, ensures
functionality, efficiency and low emissions under any conditions.
The ACC system uses an ionisation sensor immersed in the burner flame,
whose information allows the control board to operate the gas valve that
regulates the fuel. This sophisticated control system provides the auto-
regulation of the combustion, so there is no need for an initial calibration.
The ACC system is able to adapt the boiler to operate with different gas
compositions, different outlet pipes lengths and different altitudes (within
the specified design limits).
The ACC system can also perform an auto-
diagnostic operation that locks out the burner before the permitted upper
emission limit is exceeded
.
EXCLUSIVE
is a type C condensing wall-hung boiler to be used for heating
and the production of domestic hot water: depending on the fume discharge
accessory used, it is classified in categories B23P;B53P; C13,C13x;
C33,C33x; C43,C43x; C53,C53x; C63,C63x; C83,C83x; C93,C93x
.
In
B23P
configuration (when installed indoors), the appliance cannot
be installed in bedrooms, bathrooms, showers or where there are open
fireplaces without a proper air flow. The room where the boiler is installed
must have proper ventilation. Detailed requirements for the installation of
the flue, the gas piping and for ventilating the room, can be found in UNI
7129-7131.
In configuration
C
, the appliance can be installed in any type of room (there
are no limitations due to ventilation conditions or room volume).
3 INSTALLATION
3.1 Cleaning the system and characteristics of the water
In the case of a new installation or replacement of the boiler, it is necessary
to clean the heating system. To ensure the device works well, top up
the additives and/or chemical treatments (e.g. anti-freeze liquids, filming
agents, etc.) and check the parameters in the table are within the values
indicated.

Before installation, wash all system piping carefully in order to remove
any residues that may impair the operation of the appliance.
b
Under the safety valve, install a water collecting funnel with the corre-
sponding discharge in the event of leaks due to the overpressure of the
heating system. The domestic hot water circuit does not need a safety
valve, but make sure that the pressure of waterworks does not exceed 6
bar. In case of doubts, install a pressure reducer.
