Boiler Installation; Hydraulic Connections - Beretta B.A.I Manual De Instalacion Y Uso

1.
Our boilers are built and checked down to the smallest detail
in order to protect users and fitters from injury. After working on
the product, fitters must check the electrical connections are
correct, making especially sure that no bare sections of wires
stick out from the terminal board in order to protect people
from electrocution.
This instructions manual and the user manual are integral
parts of the product. Make sure they remain with the boiler,
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.
This boiler may only be installed and serviced by qualified
fitters who satisfy the requirements of local rules. Work must
be done in compliance with local rulesand subsequent
updates.
The boiler must be serviced at least once a year. This should
be booked in advance with the Technical Assistance Service.
The installer shall instruct the user in the operation of the
boiler and the safety devices.
This boiler may only be used for what it was expressly built to
do. The manufacturer declines all contractual and non-
contractual liability for injury to persons or animals or damage
to property deriving from errors made during installation,
adjustment and servicing and from improper use.
After removing the packaging, make sure the contents are
undamaged and complete. If this is not the case, contact your
dealer.
We recommend always being careful to control the degree of
wear of the keep-alive anode during ordinary maintenance jobs.
The safety valve outlet must be connected to a suitable
collection and venting system. The manufacturer declines all
liability for any damage caused by the safety valve.
Immediately after installation, inform the user that:
- in the event of leaks, he/she must shut off the water supply
and promptly inform the Technical Assistance Service
- the operating pressure of the system ranges between 1 and
1,5 bar and must never be greater than 3 bar. If necessary,
contact the Technical Assistance Service
- if the boiler is not planned to be used for a long period, he/
she should call in the Technical Assistance Service to perform
the following operations:
- turn off the main boiler and general system switches
- close the gas and water taps on both the heating and
domestic hot water circuits
- drain the heating and domestic hot water circuits to prevent
freezing.
Safety measures:
the boiler should not be used by children or unassisted disabled
people
electrical devices or equipment, such as switches, appliances,
etc., should not be used if there is a smell of gas or fumes. If
there is a gas leak, open all the doors and windows to ventila-
te the area, turn off the general gas tap and immediately call
the Technical Assistance Service
do not touch the boiler barefoot or if parts of your body are wet
or damp
before cleaning, disconnect the electricity supply by turning
off the two-position system switch and the main control panel

GENERAL SAFETY DEVICES
INSTALLER'S MANUAL
do not pull, detach or twist the wires from the boiler even if
they are not connected to the power supply
do not block or reduce the size of the ventilation openings in
the room. Only for B.A.I. models: ventilation openings are
necessaries to a right combustion
do not leave inflammable containers or substances in the room
keep packaging out of reach of children.

Boiler must only be installed by qualified personnel. Boiler is avail-
able in the following models:
Model Type
B.A.I. Combined
B.S.I. Combined
Boiler B.A.I. is a B -type wall boiler for DHW production and
11BS
heating. This kind of appliance can't be installed in bedrooms,
bathrooms or in those rooms where a fireplace without an air in-
take system should be present.
Boiler B.S.I. is a C-type wall boiler for DHW production and heat-
ing. Class C appliances can be installed in any kind of room as
long as the fumes discharge and the comburent air intake are
taken outside the room. The following types of fumes outlet are
available for this kind of boiler: B22; C12, C12x; C22; C32, C32x;
C42, C42x; C52, C52x; C62, C62x; C82, C82x. Installation must
comply with local standards and regulations in force.
For proper installation, we remind you that:
- the boiler must not be installed over a kitchen or any other cooking
equipment
- it is forbidden to leave inflammable substances in the room
- suitably insulate heat-sensitive walls (e.g.: in wood)
- minimum spaces are to be left in order to allow maintenance
operations: at least 2,5 cm every side and 20 cm under the boiler.
Keep the distance of 370 mm from the bottom of the boiler to
the furniture casing: there must be sufficient space for
dismantling operations if the magnesium anode has to be
cleaned.
Support plate and integrated pre-installation template are pro-
vided for with the boiler (fig. 2).
Mounting instructions:
• fix the boiler support plate (F) with the template (G) to the wall
and use a plumb to check that it is perfectly horizontal
• trace out 4 holes (ø 6 mm) for fixing the boiler support plate (F)
and 2 holes (ø 4 mm) for fixing the preinstallation template (G)
• make sure all the measurements are correct, then drill holes in
the wall using a drill and point with the diameter given previously
• fix the plate to the wall by the supplied anchor screws
• make hydraulic connections.

If water hardness exceeds 28°Fr, it is recommended to use water
softeners, to prevent any limestone deposit in boiler due to
excessively hard water.
