2 - BOILER DESCRIPTION

Quadra II C.A.I. is a wall-mounted type B11BS boiler for heating and

the production of domestic hot water. This type of appliance cannot

be installed in bedrooms, bathrooms or showers, or in rooms with

open ues without adequate ventilation.

The Quadra II C.A.I. boiler is tted with the following safety devices:

- Safety valve and water pressure switch intervening in cases of

insufcient or excessive water pressure (max 3 bar-min 0.7 bar).

- Temperature limit thermostat intervening by putting the boiler into

safety stop if the temperature in the system exceeds the limit

according to current local and national regulations

- Fumes thermostat intervenes by blocking the boiler into a safety

standstill status if there is a spillage of combustion products in

the hood; it is located on the right hand tile of the vent-damper

draught breaker device Intervention of safety devices indicates

a potentially dangerous boiler malfunction; contact the technical

assistance service immediately.

The ue gas thermostat not only intervenes for a fault in the

combustion products outlet system, but also with various

atmospheric conditions. One can therefore try to start up the boiler

again after waiting a short while (see "Ignition and operation"

section).

Repeated intervention of the fumes thermostat signies

evacuation of combustion products into the boiler room

with possibly incomplete combustion and formation of

carbon monoxide, a highly dangerous condition. Call the

technical assistance service immediately.

The boiler must never be put into service, not even

temporarily, if the safety devices are not working or have

been mishandled.

Safety devices must be replaced by the technical assistance

service, using original manufacturer parts only.

After repairs carry out a trial ignition.

3 - INSTALLATION REGULATIONS

This natural draught boiler is intended to be connected only to

a ue shared between multiple dwellings in existing buildings

that evacuates the residues of combustion to the outside of

the room containing the boiler. It draws the combustion air

directly from the room and incorporates a draught diverter.

Due to lower efciency, any other use of this boiler shall be

avoided and would result in higher energy consumption and

higher operating costs.

Quadra II 24 C.A.I.

3.1 Installation regulations

Installation must be carried out by qualied personnel.

Always comply with national and local regulations.

POSITION

Class B appliances cannot be installed in bedrooms, bathrooms or

showers, or in rooms with open ues without adequate ventilation.

It is imperative that the room in which a gas appliance is installed

has a sufcient inow of air to supply the quantity of air necessary

for normal combustion and ensure proper ventilation of the room

itself. Natural direct ventilation with external air must be provided

for via:

- permanent openings in the walls of the room in which the

appliance is installed leading outdoors. These openings must be

made in such a way as to ensure that the orices on both the

internal and external side of the wall cannot be obstructed or

be reduced in effective diameter, the orices themselves must

be protected with metal grilles or similar means and must be

situated near oor level and in a location that does not interfere

with the function of the ue exhaust system (where this position

is not possible, the diameter of the ventilation openings must be

increased by at least 50%)

- while single or multiple branched the ventilation ducts may be used.

The ventilation air must be sourced directly from outside the

building, away from sources of pollution. Indirect ventilation, with

air drawn from rooms next to the room in which the appliance

is installed, is permitted, provided that the limitations indicated

by current local regulations. The room in which the boiler is to

be installed must be adequately ventilated in compliance with

applicable legislation. Detailed prescriptions for the installation

of the ue, gas piping and ventilation ducting are given in current

local regulations. The aforementioned regulations also prohibit the

installation of electric fans and extractors in the room in which the

appliance is installed. The boiler must have a xed outward leading

exhaust duct with a diameter not smaller than the exhaust hood

collar. Before tting the exhaust outlet connector to the ue, check

that the ue has adequate draught and has no restrictions and that

the exhausts of no other appliances are connected to the same

ue pipe. When connecting to a pre-existing ue pipe, check that

the latter is perfectly clean, as deposits may detach from the wall

of the pipe during use and obstruct the passage of the ue gases,

creating a situation of severe danger for the user.

Quadra II 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 inammable 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

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.

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

elements 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

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

deactivates 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 specic, 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

circuit. The boiler component materials are resistant to ethylene

glycol based anti-freeze liquids.

3.2 Cleaning the system and characteristics of the

heating circuit 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.

antifreeze liquids, lming agents, etc.) and check the parameters in

the table are within the values indicated.

In case of replacement of Beretta boilers from previous type, there

is an adaptation kit of hydraulic connections available.

3.4 Electric connection

The boilers leave the factory completely wired with the power cable

already connected and they only need the connection of the room

thermostat (TA) to be carried out in the specic 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

- turn the instrument panel upside down

- remove the terminal board cover (g. 8)

- insert the cable of the possible T.A. (g. 9).

The room thermostat must be connected as indicated on the wiring

diagram.

Room thermostat input in safety low voltage.

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 and complies

with the standard EN 60335-1.

It is compulsory to carry out connection with an efcient 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 appliance.

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.

ENGLISH

3.5 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.

3.6 Fumes exhaustion and air suction

Observe applicable legislation regarding ue gas exhaustion.

The exhaust system must be made using rigid ducting, the joints

between elements must be hermetically sealed and all components

must be resistant to heat, condensation and mechanical stress and

vibration.

Non insulated outlet pipes are potential sources of danger.

The apertures for the combustion air must be realised in compliance

with applicable legislation. If condensation forms, the exhaust duct

must be insulated.

Figure 12 shows a top-down view of the boiler with the dimensions

for the ue gas exhaust outlet.

Flue gas safety system

The boiler features a system monitoring that ue gases are correctly

exhausted which arrests the boiler in the event of a fault: ue gas

thermostat - g. 11. To restore normal operation, turn the function

selector to (3 - g.1a), wait a few seconds, then turn the function

selector into the desired position.

If the fault persists, call a qualied technical from the Technical

Support Service. The ue gas exhaustion monitoring system must

never be bypassed or rendered inoperable. Use only original

replacement parts when replacing the whole system or faulty

system components.

3.7 Filling the heating system (g. 13)

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 efcient air separator so no manual intervention

is needed. The burner switches on only if the air relief phase is

nished.

3.8 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.

3.9 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 (3 - 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 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 within the area

divided into segments (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 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): rotate the domestic hot water

temperature adjustment knob (4 - 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 standby

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 monitor 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 the heating water temperature

To adjust the heating water temperature, turn the knob with symbol

within the area divided into segments (g. 2b).

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

chapter "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.

Quadra II 24 C.A.I.

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 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

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

presence 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

simulation 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

Electric card in voltage (230 Volt)

- turn the heating water temperature adjustment knob B (g. 17)

until it reaches the minimum heating value as indicated in the

multigas table

- insert the jumper JP2 (g. 16)

- turn the domestic hot water temperature adjustment knob C (g.

17) until it reaches the maximum heating value as indicated in

the multigas table

- remove the jumper JP2 to store the maximum heating value

- remove the jumper JP1 to store the heating minimum value and

to get out the calibration procedure.

Disconnect the pressure gauge and retighten the pressure test

point screw.

To nish the calibration function without storing the set values,

proceed as follows:

a) set the mode selector to position (OFF)

b) remove power supply voltage

c) remove JP1/JP2

The calibration function is automatically nished, without

storing minimum and maximum values, after 15 minutes of

its activation.

The function is automatically nished also in case of denitive

stop or lockout.

Also in this case, function conclusion DOES NOT provide

values storing.

Note

To calibrate only maximum heating, it is possible to remove the

jumper JP2 (to store the maximum) and then get out from the

function, without storing the minimum, setting the mode selector to

(OFF) or removing the voltage from the boiler.

After each intervention on the adjustment element of the gas

valve, seal it with sealing varnish.

When adjustment is complete:

- restore set temperature with the room thermostat to the desired

temperature

- set the heating water temperature selector to the desired position

- close the instrument panel

- pull the shell back in place.

4.6 Gas conversion operations

Conversion from a family gas to other family gas can be performed

easily also when the boiler is installed.

The boiler is designed to operate with methane gas (G20) according

to the product label.

It is possible to convert the boilers from one gas type to another by

using the appropriate kit supplied upon request:

- Methane conversion kit

- LPG conversion kit.

For disassembly refer to instructions below:

- remove power supply from the boiler and close the gas tap

- remove the components to access to the internal parts of the

boiler (g. 19)

- disconnect the spark plug cable connection

- remove the burner xing screws and remove the latter with the

spark plug attached and corresponding cables

- using a socket or fork spanner, remove the nozzles and the

washers and replace them with the ones in the kit

- if the conversion is from methane gas to LPG, mount the ange

contained in the kit and x it to the burner with the supplied

screws

- if the conversion is from LPG to natural gas, remove the ange

from the burner.

Use and assemble the washers contained in the kit also

in case of manifolds without washers.

- reinsert the burner in the combustion chamber and tighten the

screws xing it to the gas manifold

- restore connection of the spark plug cable

- overturn the control instrument panel towards the boiler front part

- open the card cover

- on the control card (g. 16):

- if the conversion is from methane gas to LPG, insert the jumper

in position JP3

- if the conversion is from LPG to methane gas, remove the

jumper from position JP3

- reposition the components previously removed

- restore voltage to the boiler and reopen the gas tap (with boiler in

operation, check correct seal of the gas feeding circuit connections).

Conversion must be carried out by qualied personnel.

After conversion, adjust the boiler again following

the indications in specic section and apply the new

identication label contained in the kit.

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 operations.

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 (3 - 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 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 within the

area marked (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

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 (4 - 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 display 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 the heating water temperature

To adjust the heating water temperature, turn the knob with symbol

(within the area divided into segments g. 2b).

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 temperature, 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

chapter "Light signals and faults"). The digital monitor indicates the

fault code detected (g. 6a).
