- if the boiler has not been used for a long time, it is recommended
that the Technical Assistance Service performs, at least, the following operations:
• turn “off” the main switch of the appliance and the general
switch of the system
• 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
- boiler maintenance must be carried out at least once a year. This
should be booked in advance with the Technical Assistance Service.
For safety, always remember that:
The boiler should not be used by children or unassisted disabled
people.
It is dangerous to activate electrical devices or appliances,
such as switches, home appliances, etc., if you smell gas or
fumes. In the event of gas leaks, ventilate the room opening
doors and windows; close the gas general tap; contact the
qualied personnel from the Technical Assistance Service immediately.
Do not touch the boiler while barefoot or if parts of your body
are wet or damp.
Before cleaning operations, disconnect the boiler from the
main power supply by turning “OFF” the two position system
switch and the main control panel switch.
Do not modify safety and adjustment devices without the
manufacturer's permission and relative instructions.
Do not pull, disconnect or twist the electric cables coming

2 - BOILER DESCRIPTION
Quadra II C.S.I. is a C-type wall-mounted boiler for heating and
production of domestic hot water: according to the ue gas outlet
device, the boiler is classied in categories B22P,B52P; C12,C12x;
C22 (where required); C32,C32x; C42,C42x; C52,C52x; C62,C62x;
C82,C82x; C92,C92x.
In conguration B22P and B52P (when installed indoors), the ap-
pliance cannot be installed in bedrooms, bathrooms, showers or
where there are open replaces without a proper air ow. The room
where the boiler is installed must have proper ventilation.
In conguration C, the appliance can be installed in any type of
room and there are no limitations due to ventilation conditions or
room volume.
3 - INSTALLATION REGULATIONS
3.1 Installation regulations
Installation must be carried out by qualied personnel.
Always comply with national and local regulations.
POSITION
Quadra II C.S.I. can be installed indoors (g. 2).
The boiler has protection that guarantees correct operation with a
temperature range from 0°C to 60°C.
To take advantage of protections, the appliance must be able to
start up, since any lockout condition (for example, absence of gas or
electrical supply, or safety intervention) deactivates the protections.
MINIMUM DISTANCES
In order to have access to the boiler to perform regular maintenance
operations, respect the minimum spaces foreseen for installation
(g. 3).
For correct appliance positioning:
- do not place it on a cooker or other cooking device
- do not leave inammable products in the room where the boiler is
installed
- heat sensitive walls (for example, wooden walls) must be protected
with proper insulation.
IMPORTANT
Before installation, wash every system piping carefully in order to
remove any residues that may impair the operation of the appliance.
Under the safety valve, install a water collecting funnel with the
corresponding discharge in the event of leaks due to the overpres-
sure 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.
Prior to ignition, make sure that the boiler is designed to operate
with the gas available; this can be checked by the message on the
packaging and the adhesive label indicating the gas type.
It is very important to highlight that in some cases the smoke pipes
are under pressure and therefore, the connections of several ele-
ments must be airtight.
ANTI-FREEZE SYSTEM
The boiler is tted as standard with an automatic anti-freeze system
that activates when the temperature of the water in the primary
circuit falls below 6 °C. This system is always active, guaranteeing
boiler protection to an outdoor temperature level of -3 °C. To take
EN
4
ENGLISH
advantage of this protection (based on burner operation), the boiler
must be able to switch itself on; any lockout condition (e.g. lack of
gas/electricity supply, or safety device intervention) therefore deac-
tivates the protection. The anti-freeze protection is also active when
the boiler is on standby. In normal operation conditions, the boiler
can protect itself against freezing. If the machine is left unpowered
for long periods in areas where temperatures may fall below 0 °C,
and you do not want to drain the heating system, you are advised to
add a specic, good quality anti-freeze liquid to the primary circuit.
Carefully follow the manufacturer's instructions with regards not
only the percentage of anti-freeze liquid to be used for the minimum
temperature at which you want to keep the machine circuit, but also
the duration and disposal of the liquid itself.
For the domestic hot water part, we recommend you drain the cir-
cuit. The boiler component materials are resistant to ethylene glycol
based anti-freeze liquids.
3.2 Securing the boiler to the wall and hydraulic connections
To fasten the boiler to the wall, use the cardboard template (g.
4-5) in the packaging. The position and size of the hydraulic con-
nections are indicated below:
M heating outlet 3/4”
AC DHW outlet 1/2”
G gas connection 3/4”
AF DHW inlet 1/2”
R heating return line 3/4”
In case of replacement of Beretta boilers from previous type, there
is an adaptation kit of hydraulic connections available.
3.3 Electric connection
The boilers leave the factory completely wired with the power cable
already connected and they only need the connection of the ambient
thermostat (T.A.) to be carried out in the specic terminals.
To access the terminal board:
- turn off the system general switch
- undo the xing screws (A) of the shell (g. 6)
- move forward and then upwards the shell base to unhook it from
the chassis
- undo the xing screws (B) of the instrument panel (g. 7)
- turn the instrument panel upside down
- remove the terminal board cover (g. 8)
- insert the cable of the possible T.A. (g. 9).
The ambient thermostat must be connected as indicated on the
wiring diagram.
Ambient thermostat input in safety low voltage (24 Vdc).
The connection to the mains supply must be carried out through a
separation device with an omnipolar opening of at least 3.5mm (EN
60335-1, category III).
The appliance operates with an alternating current of 230 Volt/50
Hz and complies with the standard EN 60335-1.
It is compulsory to carry out connection with an efcient earth
circuit, according to national and local legislation.
It is advisable to comply with neutral phase connection (L-N).
The earth wire must be a couple of centimetres longer than the
others.
Do not use gas and/or water pipes to earth electrical ap-
pliance.
The manufacturer declines liability for any damage if the appliance
was not connected to an earth circuit.
Use the power cable supplied to connect the boiler to the mains
power supply.
If the power cable is replaced, use a cable type HAR H05V2V2-F,
3 x 0.75 mm2, with max. outside diameter 7 mm.
3.4 Gas connection
Before connecting the appliance to the gas network, check that:
- national and local regulations are complied
- the gas type is the one suitable for the appliance
- the piping is clean.
The gas pipe must be installed outdoor. If the pipe goes through
the wall, it must go through the central opening, in the lower part
of the template.
It is advisable to install a lter of suitable dimensions on the gas line
if the distribution network had solid particles.
Once the appliance has been installed check that connections are
sealed according to current installation regulations
3.5 Fumes exhaustion and air suction
For fumes exhaustion, refer to the current local and national regula-
tions. Always comply with local standards of the Fire Department,
the Gas Company and with possible municipal dispositions.
The release of combustion products is assured by a centrifugal fan
placed inside the combustion chamber and its correct operation
is constantly checked by a pressure switch. The boiler is supplied
without the ue gas outlet/air suction kit, since it is possible to use
the accessories for appliance with a forced draught sealed chamber
that better adapts to the installation characteristics.
It is essential for ue gas release and the restoration of boiler combustion air to use certied pipes and that connection is carried out
correctly as indicated by the instructions supplied with the ue gas
accessories.
With only one smoke pipe you can connect more pieces of appli-
ance provided that every piece of appliance is sealed chamber type.
“FORCED OPEN” INSTALLATION (TYPE B22P/B52P)

Once the hydraulic connections have been carried out, ll the heating system. This operation must be carried out with cold system
following this instructions:
- turn by two or three turns the automatic relief valve cap (I)
- make sure the cold water inlet tap is open
- turn on the lling tap (L) until the pressure indicated by the water
pressure gauge is between 1 and 1.5 bar.
Once lling is complete, close the lling tap.
The boiler has an efcient air separator so no manual intervention is
needed. The burner switches on only if the air relief phase is nished.
3.7 Emptying the heating system (g. 13)
To empty the system, proceed as follow:
- switch off the boiler
- loose the boiler outlet tap (M)
- empty the lowest points of the system.
3.8 Emptying the domestic hot water (g. 13)
When there is risk of frost, the domestic hot water system must be
emptied in the following way:
- close the main tap of the water mains
- open all the hot and cold water taps
- empty the lowest points.
WARNING
When carrying out the discharge of the safety valve (N), it must be
connected to a suitable collection system. The manufacturer is not
responsible for possible damages due to safety valve operation.
4 IGNITION AND OPERATION
4.1 Preliminary checks
First ignition is carried out by competent personnel from an
authorised Technical Assistance Service Beretta.
Before starting up the boiler, check:
a) that the supply networks data (electric, water, gas) corresponds
to the label data
b) that piping leaving the boiler is covered by thermal insulation
sheath
c) that ue gas extraction and air suction pipes work correctly
d) that conditions for regular maintenance are guaranteed if the
boiler is placed inside or between furniture
e) the seal of the fuel adduction system
f) that fuel capacity corresponds to values requested by the boiler
g) that the fuel supply system has the correct capacity for the
necessary capacity to the boiler and that it has all the safety
and control devices prescribed by current regulations.
4.2 Appliance ignition
To start-up the boiler it is necessary to carry out the following
operations:
- power the boiler
- open the gas tap present in the system to allow fuel ow
- turn the mode selector (1 - g. 1a) to the desired position:
Summer mode: turning the selector to the summer symbol (g.
2a) the traditional function of only domestic hot water is activated.
If there is a domestic hot water request, the boiler status indicator
LED lights up with a xed green light. The digital display shows the
hot water system temperature, the icon to indicate the hot water
supply and the ame icon (g. 4a).
Winter mode: by turning the mode selector (g. 2b) within the
area marked, the boiler provides domestic hot water and heating. If
there is a heat request, the boiler switches on and the boiler status
indicator LED lights up with a xed green light. The digital display
indicates the heating water temperature, the icon to indicate heating
and the ame icon (g. 3a). If there is a domestic hot water request,
the boiler switches on and the boiler status indicator LED lights up
with a xed green light. The digital display shows the hot water
system temperature, the icon to indicate the hot water supply and
the ame icon (g. 4a).
Pre-heating (faster hot water):turning the domestic hot water
temperature adjustment knob (2 - g.1a) to the symbol (g. 5a),
activates the pre-heating function. This function keeps the water
in the domestic hot water exchanger hot, to reduce stand-by times
when a request is made. When the pre-heating function is enabled,
the yellow LED next to the symbol is lit. The monitor indicates
the delivery temperature of the heating water or the domestic hot
water, according to the current request. During burner ignition
following a pre-heating request, the digital dyspaly indicates the
symbol (g. 5b). To deactivate the pre-heating function, rotate
the domestic hot water temperature adjustment knob back to the
symbol. The yellow LED will switch off. Bring the domestic hot
water temperature adjustment knob back to the required position.
This function cannot be activated when the boiler is OFF: function
selector (g.6b) on (OFF).
Adjustment of domestic hot water temperature
To adjust domestic water temperature (bathrooms, showers, kitchen, etc.),
turn the knob with symbol (g. 8a) within the area marked 1 and 6
.
Rotate clockwise to increase the temperature and anticlockwise to
reduce it. On the control panel, the green LED ashes with ON for
0.5 seconds, OFF for 3.5 seconds.
The boiler is stand-by status until, after a heat request, the burner
switches on and the indicator LED turns xed green to indicate ame
presence. The boiler continues to operate until the temperatures set
on the boiler are reached, or the heat request is met; after which it
goes back on stand-by.
If the red LED indicator near the symbol on the control panel
lights up, this means the boiler is in temporary stop status (see the
chapter about light signals and faults). The digital monitor indicates
the fault code detected (g. 6a).
Automatic Adjustment Control System Function (S.A.R.A., g.
7a)
By setting the heating water temperature selector to the area
marked by AUTO - temperature value from 55 to 65°C - the
S.A.R.A. self-adjusting system is activated, the green LED ashes
(frequency 0.1 sec. on; then 0.1 sec. off; for 0.5 seconds): the boiler
varies the delivery temperature according to the closing signal of
the room thermostat. When the temperature set with the heating
water temperature selector is reached, a 20 minutes count begins.
If during this period the room thermostat still requests heat, the
value of the set temperature automatically increases by 5 °C.
When the new value is reached, other 20 minutes count begins.
If during this period the room thermostat still requests heat, the
value of the set temperature automatically increases by 5 °C.
This new temperature value is the result of the temperature set
manually with the heating water temperature selector and the in-
crease of +10 °C of the S.A.R.A function.
After the second cycle the temperature value should be kept at the
set value +10°C until the request of the room thermostat is satis-
ed.
4.3 Switching off
Temporary switching off
In case of absence for short periods of time, set the mode selector
(g 6b) to (OFF), the green LED ashes ON for 0.5 seconds,
OFF for 3.5 seconds.
In this way (leaving the electricity and fuel supplies enabled), the
boiler is protected by the following systems:
- Anti-frost device: when the temperature of the water in the boiler
falls below 5°C, the circulator and, if necessary, the burner are
activated at minimum output levels to bring the water temperature
back to the values for safety (35°C). During the anti-frost cycle,
the symbol appears on the digital monitor.
- Circulator anti-blocking function: an operation cycle is activated
every 24 hours.
Long period switching off
In case of absence for long periods of time, set the mode selector
(g 6b) to (OFF), the green LED ashes ON for 0.5 seconds,
OFF for 3.5 seconds.
Turn the main system switch OFF. Close the gas and water taps of
the heating and domestic hot water system. In this case, anti-frost
device is deactivated: drain the systems, in case of risk of frost.
4.4 Light signals and faults
The operating status of the boiler is shown on the digital display,
following is a list of the types of displays.

4.5 Adjustments
The boiler has already been adjusted by the manufacturer.
If it is necessary to adjust it again, for example after extraordinary
maintenance, after replacement of gas valve or after gas conversion,
carry out the following procedure.
The maximum output adjustment must be carried out in
the sequence indicated exclusively by qualied personnel.
- remove the shell unscrewing the xing screws A (g. 6)
- unscrew by two turns the screw of the pressure test point downstream the gas valve and connecting the pressure gauge
- disconnect the compensation inlet of the air distribution box
4.5.1 Maximum power and minimum domestic hot water adjust-
ment
- Fully open the hot water tap
- on the control panel:
- set the mode selector to (summer) (g. 2a)
- turn the domestic hot water temperature selector to its maximum
(g. 8a)
- power the boiler setting the system main switch to “on”
- check that the pressure on the pressure gauge is stable; or with
a milliammeter in series to the modulator, make sure that the
modulator supplies the maximum available current (120 mA for
G20 and 165 mA for LPG).
- carefully prise out the protection cap of the adjustment screws,
using a screwdriver (g. 15)
- with a fork spanner CH10 use the adjustment nut of the maximum
output in order to obtain the value indicated in table "Technical data"
- disconnect the modulator faston
- wait until the pressure on the pressure gauge is stable at minimum value
- paying attention not to press the internal shaft, use an Allen
spanner to turn the red adjustment screw for domestic hot water
minimum temperature regulation, calibrating it until the pressure
gauge reads the value indicated in the table "Technical data"
- reconnect the modulator faston
- close the domestic hot water tap
- carefully ret the protection cap of the adjustment screws.
4.5.2 Minimum and maximum heating electric adjustment
The “electric adjustment” function is activated and deactivated
exclusively by the jumper (JP1) (g. 16).
The two LEDs (GREEN and RED) on the control panel ash simultaneously for approximately 4 seconds.
The function can be enabled in the following way:
- by powering the card with the jumper JP1 inserted and the mode
selector in winter position, independently from the possible pres-
ence of other operation request.
- by inserting the jumper JP1, with the mode selector in winter position, without heat request in progress.
By activating the function the burner is ignited through simula-
tion of heat request in heating.
To perform calibration operations, proceed as follow:
- switch off the boiler
- remove the shell and access the card
- insert the jumper JP1 (g. 16) to enable the knobs placed on the
control panel to the minimum and maximum heating adjustment
functions.
- make sure that the mode selector is in winter position (see section
4.2).
- power the boiler

USER
1A GENERAL WARNINGS
The instruction manual is an integral part of the product and it must
therefore be kept carefully and must accompany the appliance; if the
manual is lost or damaged, another copy must be requested from the
Technical Assistance Service.
Boiler installation and any other assistance and maintenance
operation must be carried out by qualied personnel according
to current local and national regulations.
For installation, it is advisable to contact specialised personnel.
The boiler must only be used for the application foreseen by
the manufacturer. The manufacturer shall not be liable for any
damage to persons, animals or property due to errors in instal-
lation, calibration, maintenance or due to improper use.
The safety and automatic adjustment devices must not be
modied, during the system life cycle, by the manufacturer or
supplier.
This appliance produces hot water, therefore it must be con-
nected to a heating system and/or a domestic hot water mains,
compatible with its performance and output.
In case of water leakage, close the water supply and contact
the Technical Assistance Service immediately.
In case of absence for long periods time, close the gas supply
and switch off the electrical supply main switch. In case of risk
of frost, empty the boiler.
From time to time check that the operating pressure of the
hydraulic system does not decrease under 1 bar.
In case of failure and/or malfunctioning, deactivate the
appliance, and do not try to repair or intervene directly on it.
Appliance maintenance must be carried out at least once a
year: program it with the Technical Assistance Service will avoid
wasting time and money.
Boiler use requires to strictly observe some basic safety rules:
Do not use the appliance in any manner other than its intended
purpose.
It is dangerous to touch the appliance with wet or damp body
parts and/or in bare feet.
Under no circumstances cover the intake grids, dissipation grids
and ventilation vents in the installation room with cloths, paper
or any other material.
Do not activate electrical switches, telephone or any other object
that causes sparks if there is a smell of gas. Ventilate the room
by opening doors and windows and close the gas central tap.
Do not place anything in the boiler.
Do not perform any cleaning operation if the appliance is not
disconnected from the main power supply.
Do not cover or reduce ventilation opening of the room where
the generator is installed.
Do not leave containers and inflammable products in the
installation room.
Do not attempt to repair the appliance in case of failure and/or
malfunctioning.
It is dangerous to pull or twist the electric cables.
Children or unskilled persons must not use the appliance.
Do not intervene on sealed elements.
For better use, remember that:
- a periodic external cleaning with soapy water not only improves
its aesthetic aspect but also preserves panelling from corrosion,
extending its life cycle;
- if the wall-mounted boiler is enclosed in pendant furniture, leave
at least 5 cm for ventilation and maintenance;
- installation of an ambient thermostat will favour a greater comfort,
a more rational use of the heat and energy saving; the boiler can
also be connected to a programming clock in order to manage
ignition and switching off during the day or week.
2A IGNITION
First ignition must be carried out by personnel from the Technical
Assistance Service. At the same time, if it is necessary to put the
appliance in service again, carefully follow the described opera-
tions.
To start-up the boiler it is necessary to carry out the following operations:
- power the boiler
- open the gas tap present in the system to allow fuel ow
- turn the mode selector (1 - g. 1a) to the desired position:
Summer mode: turning the selector to the symbol summer
(g. 2a) the traditional function of only domestic hot water is ac-
tivated. If there is a domestic hot water request the boiler status
indicator LED lights up with a xed green light. The digital display
shows the hot water system temperature, the icon to indicate the
hot water supply and the ame icon (g. 4a).
Winter mode: by turning the mode selector within the area mar-
ked (g. 2b), the boiler provides domestic hot water and heating.
If there is a heat request, the boiler switches on and the boiler
status indicator LED lights up with a xed green light. The digital
monitor indicates the heating water temperature, the icon to in-
dicate heating and the ame icon (g. 3a). If there is a domestic
hot water request, the boiler switches on and the boiler status
indicator LED lights up with a xed green light. The digital display
shows the hot water system temperature, the icon to indicate the
hot water supply and the ame icon (g. 4a)
Pre-heating (faster hot water): turning the domestic hot water
temperature adjustment knob (2 - g. 1a) to the symbol (g.
5a), to activate the pre-heating function. This function keeps the
water in the domestic hot water exchanger hot, to reduce stand-by
times when a request is made. When the pre-heating function is
enabled, the yellow LED next to the symbol is lit. The digital dis-
play indicates the delivery temperature of the heating water or the
domestic hot water, according to the current request. During burner
ignition following a pre-heating request, the display indicates the
symbol (g. 5b). To deactivate the pre-heating function, rotate
the domestic hot water temperature adjustment knob back to the
symbol. The yellow LED will switch off. Bring the domestic hot
water temperature adjustment knob back to the required position.
This function cannot be activated when the boiler is OFF: function
selector (g.6b) on OFF.
Adjustment of domestic hot water temperature
To adjust domestic water temperature (bathrooms, showers, kitchen, etc.),
turn the knob with symbol (g. 8a) within the area marked 1 and 6.
Rotate clockwise to increase the temperature and anticlockwise to
reduce it. On the control panel, the green LED ashes with ON for
0.5 seconds, OFF for 3.5 seconds.
The boiler is stand-by status until, after a heat request, the burner
switches on and the indicator LED turns xed green to indicate ame
presence. The digital display shows the hot water system tempe-
rature, the icon to indicate the hot water supply and the ame icon
The boiler will be in function until the adjusted temperature is
reached, afterwards it will be in “standby” again.
If the red LED indicator light near the symbol on the control
panel lights up, this means the boiler is in temporary stop status
(see "Light signals and faults"). The digital monitor indicates the
fault code detected (g. 6a).
Environment Automatic Adjustment System Function (S.A.R.A.,
g. 7a)
By setting the heating water temperature selector to the area marked
by AUTO - temperature value from 55 to 65°C - the S.A.R.A. selfadjusting system is activated, the green LED ashes (frequency
0.1 sec. on; then 0.1 sec. off; for 0.5 seconds): the boiler varies the
delivery temperature according to the closing signal of the ambient
thermostat. When the temperature set with the heating water temperature selector is reached, a 20 minutes count begins. If during
this period the ambient thermostat still requests heat, the value of
the set temperature automatically increases by 5 °C.
When the new value is reached, other 20 minutes count begins.
If during this period the ambient thermostat still requests heat, the
value of the set temperature automatically increases by 5 °C.
10
ENGLISH
This new temperature value is the result of the temperature set manually with the heating water temperature selector and the increase of
+10 °C of the S.A.R.A function.
After the second cycle the temperature value should be kept at the
set value +10°C until the request of the ambient thermostat is met.
Carefully close the tap.
Replace the mode selector on the initial position.
If pressure drop is frequent, contact the Technical Assistance Service.
5A LIGHT SIGNALS AND FAULTS

3A SWITCHING OFF
Temporary switching off
In case of absence for short periods of time, set the mode selector
(g. 6b) to (OFF), the green LED ashes ON for 0.5 seconds,
OFF for 3.5 seconds.
In this way (leaving the electricity and fuel supplies enabled), the
boiler is protected by the following systems:
- Anti-frost device: when the temperature of the water in the boiler
falls below 5°C, the circulator and, if necessary, the burner are
activated at minimum output levels to bring the water temperature
back to the values for safety (35°C). During the anti-frost cycle,
the symbol appears on the digital monitor.
- Circulator anti-blocking function: an operation cycle is activated
every 24 hours.
Long period switching off
In case of absence for long periods of time, set the mode selector
(g. 6b) to (OFF), the green LED ashes ON for 0.5 seconds,
OFF for 3.5 seconds.
Turn the main system switch OFF. Close the gas and water taps of
the heating and domestic hot water system.In this case, anti-frost
device is deactivated: empty the systems, in case of risk of frost.
4A CONTROLS
At the beginning of the heating season, and occasionally during
use, make sure the hydrometer-thermohydrometer indicates cold
system pressure values between 0.6 and 1.5 bar: this avoids system
noise levels due to the presence of air. In case of insufcient water
circulation, the boiler will switch off. Under no circumstances, water
pressure must be below 0.5 bar (red eld).
If this condition is checked, it is necessary to restore water pressure
in the boiler proceeding as follows:
- set the mode selector (g. 6b) to (OFF)
- turn on the lling tap until the pressure value is between 1 and 1.5
bar.

SYSTÈME ANTIGEL
La chaudière est équipée de série d'un système antigel automatique qui
s'active lorsque la température de l'eau du circuit primaire est inférieure
à 6 °C. Ce système est toujours actif et il garantit la protection de la
chaudière jusqu'à une température extérieure de -3 °C. Pour proter de
cet protection (par rapport au fonctionnement du brûleur), la chaudière
doit être en mesure de s'allumer elle seule ; cela signie que toute
condition de blocage (ex. manque de gaz ou d'alimentation électrique, ou
encore déclenchement d'un dispositif de sécurité) désactive la protection.
La protection antigel est active même lorsque la chaudière est en état de veille.
Dans des conditions normales de fonctionnement, la chaudière est
capable de s'autoprotéger du gel. Au cas où l'appareil serait laissé
longtemps hors tension dans des zones soumises à des températures
inférieures à 0 °C et qu'on ne souhaiterait pas vidanger l'installation de
chauffage, il est conseillé d'utiliser un liquide antigel de qualité dans
le circuit primaire. Suivre attentivement les instructions du fabricant
concernant non seulement le pourcentage de liquide antigel à utiliser
pour la température minimale à laquelle vous souhaitez maintenir le
circuit de la machine mais également la durée et le mode d'élimination
du liquide antigel.
Pour la partie sanitaire, il est conseillé de vider le circuit. Les matériaux
utilisés pour la fabrication des composants des chaudières sont résistants aux liquides antigel à base de glycols éthyléniques.
3.2 Fixation de la chaudière au mur et raccordements
hydrauliques
Pour xer la chaudière au mur, utiliser le gabarit en carton (Fig. 4-5)

- tourner le tableau de bord vers soi
- déposer la couverture du bornier (Fig. 8)
- insérer le câble de l'éventuel T.A. (Fig. 9)
Le thermostat d'ambiance doit être branché comme indiqué sur le
schéma électrique.
Entrée du thermostat d'ambiance à basse tension de sécurité
(24 Vcc).
Le branchement au réseau électrique doit être réalisé par un dispositif de
séparation avec ouverture omnipolaire d'au moins 3,5 mm (EN 60335-1,
catégorie III).
L’appareil fonctionne en courant alternatif de 230 V/50 Hz et il est
conforme à la norme EN 60335-1.
Le branchement avec une installation de mise à la terre efcace
est obligatoire, conformément aux normes nationales et locales
en vigueur.
Il est conseillé de respecter le branchement de phase neutre (L-N).
Le conducteur de terre doit être deux centimètres plus long que les
autres.
L'utilisation des tuyaux de gaz et/ou d'eau comme mise à la
terre d'appareils électriques est interdite.
Le constructeur décline toute responsabilité pour d'éventuels dommages
provoqués par l'absence de mise à la terre de l'installation.
Pour le branchement électrique, utiliser le câble d'alimentation fourni.
En cas de remplacement du câble d'alimentation, utiliser un câble
du type HAR H05V2V2-F, 3 x 0,75 mm2, diamètre max. externe 7 mm.
3.4 Raccordement de gaz
Avant d'effecteur le raccordement de l'appareil au réseau de gaz,
vérier que:
- les normes d'installation nationales et locales ont été respectées
- le type de gaz est celui pour lequel l'appareil a été prévu
- les tuyaux sont propres.
La canalisation de gaz prévue est externe. Si le tuyau traversait le mur il
devrait passer à travers le trou central de la partie inférieure du gabarit.
Il est conseillé d'installer un ltre de dimensions appropriées sur la ligne
de gaz au cas où le réseau de distribution contiendrait des particules
solides. Une fois l'installation effectuée, vérier si les jonctions réalisées
sont étanches comme prévu par les règles d'installation en vigueur.
3.5 Évacuation des produits de combustion et aspiration de
l'air
Pour l’évacuation des produits de combustion, consulter les normes
locales et nationales en vigueur. En outre, il faut toujours respecter les
normes locales des sapeurs-pompiers, de la compagnie du gaz et les
éventuelles dispositions municipales.
L’évacuation des produits de combustion est assurée par un ventilateur
placé à l'intérieur de la chambre de combustion dont le fonctionnement
correct est contrôlé constamment par un pressostat. La chaudière est fournie sans le kit d'évacuation des fumées/aspiration d'air, car il est possible
d'utiliser les accessoires pour des appareils à chambre étanche à tirage
forcé qui mieux s'adaptent aux caractéristiques typologiques d'installation.
Pour l'extraction des fumées et le rétablissement de l'air comburant de la
chaudière, il est indispensable que des tuyaux certiés soient employés
et que le raccordement soit effectué correctement, tel qu'il est indiqué
dans les instructions fournies avec les accessoires pour fumées.
Il est possible de raccorder plusieurs appareils à un conduit de fumées
unique, à condition qu'ils soient tous du type à chambre étanche.
