EN INSTALLATION MANUAL

2 - DESCRIPTION

Quadra Green C.S.I. is a type C wall-mounted condensing boiler designed

for heating and production of domestic hot water: according to the ue gas

discharge device, the boiler is classied in categories B23P, B53P, C13,

C23 (25 C.S.I.), C33, C43, C53, C63, C83, C93, C13x, C33x, C43x, C53x,

C63x, C83x, C93x.

In conguration B23P and B53P (when installed indoors), the appliance

cannot be installed in bedrooms, bathrooms, showers or where there are

open replaces without a proper air ow. The room where the boiler is in-

stalled must have proper ventilation.

In conguration 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

3.1 Installation regulations

Installation must be carried out by qualied personnel, in accordance with

the regulations in law.

POSITION

The boiler can be installed indoor and outdoor, in a partially protected place

(i.e. a place where the boiler is not exposed to direct contact or inltration of

rain, snow or hail). The boiler can operate in a temperature range from -3°C

to +60°C. For further details, refer to “Anti-freeze system” section.

ANTI-FREEZE SYSTEM

The boiler is tted as standard with an automatic anti-freeze system that

actives when the water temperature in the primary circuit falls below 6°C.

This system is always active, guaranteeing boiler protection down to an

installation area temperature of -3°C.

To take advantage of this protection, based on the burner operation, the

boiler must be able to switch itself on; any lockout condition (i.e. due to a

lack of gas or electrical supply, or the intervention of a safety device) there-

fore deactivates the protection.

By using a specic accessory, the DHW circuit can be protected in case of

temperatures lower than -3°C up to -10°C. This system is made by a series

of electrical resistances.

To use the anti-freeze protection, an electrical supply is required; this

means that any blackout or disconnection will deactivate the protection.

The anti-freeze protection is also active when the boiler is on stand-by. In

normal operation conditions, the boiler can protect itself against freezing.

In areas where temperatures may fall below 0°C, or when the machine is

left unpowered for long periods, you are advised to use a good quality anti-

freeze liquid in the primary circuit to avoid the risk of freezing if you do not

want to drain the heating system.

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 hot domestic water part, we recommend

you drain the circuit. The boiler component materials are resistant to ethyl-

ene glycol based anti-freeze liquids.

MINIMUM DISTANCES

In order to have access to the boiler to perform regular maintenance opera-

tions, respect the minimum clearances foreseen for installation (g. 9).

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 all system piping carefully in order to remove any

residues that may impair the operation of the appliance.

Connect the drain manifold to a suitable drainage system (for details, refer

to chapter 3.5). 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.

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 treat-

ments (e.g. antifreeze liquids, lming agents, etc.) and check the param-

eters in the table are within the values indicated.

3.3 Securing the boiler to the wall and hydraulic

connections

To secure the boiler to the wall, use the crossbar (g. 10) provided in the box.

The position and size of the hydraulic connections 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”

3.4 Installation of the external sensor (g. 11)

The correct operation of the external sensor is fundamental for the good

operation of the climate control.

INSTALLING AND CONNECTING THE EXTERNAL SENSOR

The sensor must be installed on an external wall of the building to be heat-

ed, observing the following indications:

it must be mounted on the side of the building most often exposed to winds

(the NORTH or NORTHWEST facing wall), avoiding direct sunlight; it must

be mounted about two thirds of the way up the wall;

it must not be mounted near doors, windows or air outlet points, and must

be kept away from smoke pipes or other heat sources.

The electrical wiring to the external sensor is made with a bipolar cable

with a section from 0.5 to 1 mm2 (not supplied), with a maximum length

of 30 metres. It is not necessary to respect the polarity of the cable when

connecting it to the external sensor. Avoid making any joints on this cable

however; if joints are absolutely necessary, they must be watertight and well

protected. Any ducting of the connection cable must be separated from live

cables (230V AC).

FIXING THE EXTERNAL SENSOR TO THE WALL

The sensor must be xed on a smooth part of the wall; in the case of ex-

posed brickwork or an uneven wall, look for the smoothest possible area.

Loosen the plastic upper protective cover by turning it anticlockwise.

After deciding on the best xing area of the wall, drill the holes for the 5x25

wall plug.

Insert the plug in the hole. Remove the board from its seat.

Fix the box to the wall, using the screw supplied.

Attach the bracket, then tighten the screw.

Loosen the nut of the cable grommet, then insert the sensor connection

cable and connect it to the electric clamp.

To make the electrical connection between the external sensor and the

boiler, refer to the “Electrical wiring” chapter.

Remember to close the cable grommet properly, to prevent any

humidity in the air getting in through the opening.

Put the board back in its seat.

Close the plastic upper protective cover by turning it clockwise. Tighten the

cable grommet securely.

3.5 Condensate collection

The system must be set up so as to avoid any freezing of the condensate

produced by the boiler (e.g. by insulating it). You are advised to install a

special drainage collection basin in polypropylene (widely available on

the market) on the lower part of the boiler (hole Ø 42), as shown in g.12.

Position the exible condensate drainage hose supplied with the boiler,

connecting it to the manifold (or another connection device which allows

inspection) avoiding creating any bends where the condensate could col-

lect and possibly freeze.

The manufacturer will not be liable for any damage resulting from the failure

to channel the condensate, or from its freezing.

The drainage connection line must be perfectly sealed, and well protected

from the risk of freezing.

Before the initial start-up of the appliance, check the condensate will be

properly drained off.

3.6 Gas connection

Before connecting the appliance to the gas supply, check that:

- national and local installation regulations are complied with

- the gas type is the one suitable for the appliance

- the piping is clean.

The gas pipe must be installed outdoors. 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 contains solid particles.

Once the appliance has been installed, check the connections are sealed

according to current installation regulations.

3.7 Electrical wiring

To access the electrical wiring, proceed as follows:

To access the terminal board:

- turn off the main switch on the system

- undo the xing screws (D) on the housing (g. 13)

- move the base of the housing forwards and then upwards to unhook it

from the chassis

- undo the xing screws (E) from the instrument panel (g. 14)

- lift then turn the instrument panel towards you (g. 15)

- detach the cover on the board casing (g. 16)

- insert the cable of any room thermostat to be tted.

The room thermostat must be connected as indicated in the wiring diagram.

Low voltage room thermostat input (24V DC).

It must be connected to the mains power supply via a double-pole isolating

switch with minimum contact gap of 3.5 mm (EN 60335/1 - category 3).

The appliance operates with an alternating current of 230 Volt/50 Hz and

complies with the standard EN 60335-1.

It is obligatory to ensure the earth connection is safe, in compliance with

the current directives.

The installer is responsible for ensuring the appliance is correctly

earthed; the manufacturer will not be liable for any damage resulting

from an incorrect or missing earth connection.

It is also advisable to respect the live-neutral connection (L-N).

The earth conductor must be a couple of cm longer than the others.

The boiler can operate with a phase-neutral or phase-phase supply.

For power supplies that are not earthed, it is necessary to use an isolating

transformer with earthed secondary.

Do not use gas and/or water pipes to earth electrical appliances.

Use the power cable supplied to connect the boiler to the mains power

supply.

If the power cable needs to be replaced, use a cable of the HAR H05V2V2-

F type, 3 x 0.75 mm2, with a maximum external diameter of 7 mm.

3.8 Filling the heating system (g. 17)

Once the hydraulic connections have been carried out, ll the heating sys-

tem.

This operation must be carried out with cold system, according to the fol-

lowing instructions:

- open the automatic air vent by turning the plug on the lower valve (A) and

upper valve (E) two or three turns, to bleed the air continuously, leave

valve plugs A-Eopen

- ensure that the cold water inlet tap is open

- open the lling tap (C) until the pressure indicated by the water gauge is

between 1 and 1.5 bar

- close the lling tap.

Note: the boiler is bled automatically via the two automatic bleed valves

Aand E, positioned on the circulator and inside the air distribution box

respectively.

If you encounter problems bleeding the boiler, proceed as described in

paragraph 3.11.

3.9 Draining the heating system (g. 17)

Before starting to drain the system, switch off the electrical supply by turn-

ing off the main switch of the system.

Close the shut-off devices on the heating system

Manually loosen the system drain valve (D).

3.10 Draining the domestic hot water system (g. 17)

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

- drain the lowest points.

3.11 Bleeding the air from the heating circuit and boiler

During the initial installation phase, or in the event of extraordinary main-

tenance, you are advised to perform the following sequence of operations:

1. Use a CH11 spanner to open the manual air vent valve located above

the air distribution box (g.18). Connect the tube (supplied with the boil-

er) to the valve, so the water can be drained into an external container.

2. Open the system lling tap located on the hydraulic unit and wait until

water begins to drain out of the valve.

3. Switch on the electricity supply to the boiler, leaving the gas tap turned off.

4. Activate a heat request via the room thermostat or the remote control

panel, so that the 3-way valve goes into heating mode.

QUADRA GREEN C.S.I.

5. Activate a DHW request as follows:

open a tap, for 30 seconds every minute so that the three-way valve

switches from heating to domestic hot water and vice versa about ten

times. In this situation, the boiler will go into alarm mode due to the

absence of gas, so it must be reset every time this happens.

6. Carry on with the sequence until only water leaks out of the manual air

vent valve, and the air ow has stopped. Close the manual air vent valve.

7. Check the system pressure level is correct (the ideal level is 1 bar).

8. Turn off the system lling tap.

9. Turn on the gas tap and ignite the boiler.

3.12 Flue gas discharge and air suction

Observe local legislation regarding ue gas discharge.

Flue gases are discharged

from a centrifugal fan located inside the combus-

tion chamber and the control board constantly checks that this is working

correctly. The boiler is supplied without the ue gas discharge/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. For ue

gas extraction and the restoration of boiler combustion air, it is essential to

only use certied piping. Connection must be carried out correctly as indicated

in the instructions supplied as standard with the ue gas

accessories.

Multiple appliances can be connected to a single smoke pipe provided that

each is a sealed chamber-type appliance. The boiler is a Type Cappliance

(sealed chamber), and must therefore have a safe connection to the ue

gas discharge pipe and to the combustion air suction pipe; these both carry

their contents outside, and are essential for the operation of the appliance.

The maximum lengths of the ducts refer to ue systems available in

the catalogue.

POSSIBLE OUTLET CONFIGURATIONS (g. 24)

B23P/B53PSuction indoors and discharge outdoors

C13-C13x Discharge via concentric wall outlet. The pipes may leave the

boiler independently, but the outlets must be concentric or suf-

ciently close together to be subjected to similar wind conditions

(within 50 cm).

C23 Discharge via concentric outlet in common smoke pipe (suction

and discharge in the same pipe).

C33-C33x Discharge via concentric roof outlet. Outlets as for C13.

C43-C43x Discharge and suction in common separate smoke pipes, but

subjected to similar wind conditions.

C53-C53x Separate discharge and suction lines on wall or roof and in ar-

eas with different pressures. The discharge and suction lines

must never be positioned on opposite walls.

C63-C63x Discharge and suction lines using pipes marketed and certied

separately (1856/1).

C83-C83x Discharge via single or common smoke pipe and wall suction line.

C93-C93x Discharge on roof (similar to C33) and air suction from a single

existing smoke pipe.

The boilers are factory set to:

25 C.S.I.: 4.900 r.p.m. (CH) and 6.100 r.p.m. (DHW) and the maximum

length that can be reached is 7 m for the ø 50 pipe, 25 m for the ø 60 pipe

and 75 m for the ø 80 pipe.

30 C.S.I.: 5.300 r.p.m. (CH) and 6.200 r.p.m. (DHW) and the maximum

length that can be reached is 5 m for the ø60 pipe and 67 m for the ø 80

pipe (not applicable for the ø 50 pipe).

Should it be necessary to achieve greater lengths, compensate the pres-

sure drop with an increase in the r.p.m.of the fan, as shown in the adjust-

4 - SWITCHING ON AND OPERATION

4.1 Switching on the appliance

When the boiler is rst started the siphon for collecting the condensate

is empty. It is therefore indispensable to create a head of water lling

the siphon before starting up, following these instructions:

- remove the siphon by releasing it from the plastic pipe connec-

ting to the combustion chamber

- ll the siphon about 3/4” full with water, making sure it is free of

any impurities

- check the oat of the plastic cylinder

- put back the siphon, being careful not to empty it, and secure it

with the clip

The plastic cylinder inside the siphon has the job of preventing combustible

gas coming out into the surroundings if the appliance is started without rst

creating the head of water in the siphon.

Repeat this operation during routine and extraordinary maintenance opera-

tions.

Every time the appliance is powered up, a series of data is shown on the

display including the ue gas sensor meter reading (-C- XX) (see paragraph

4.3 - fault A09); the automatic purge cycle then starts, lasting around 2 min-

utes. During this phase, the three LEDs light up alternately and the symbol

is shown on the monitor (g. 25).

To interrupt the automatic purge cycle proceed as follows:

access the electronic board by removing the housing, turning the instru-

ment panel towards you and opening the board casing (g. 16).

Then:

- using a small screwdriver included, press the CO button (g. 26).

Live electrical parts (230 V AC).

To start up the boiler it is necessary to carry out the following operations:

- power the boiler

- open the gas tap to allow the ow of fuel

- set the room thermostat to the required temperature (~20°C)

- turn the mode selector to the desired position:

Winter mode: by turning the mode selector (g. 27) within the marked area,

the boiler provides domestic hot water and heating. If there is a heat re-

quest, the boiler switches on and the boiler status indicator LED lights up

with a xed green light. The digital monitor indicates the heating water tem-

perature, the icon to indicate heating and the ame icon (g. 29).

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. 30).

Adjustment of the heating water temperature

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

(g. 27) within the marked area.

Depending on the type of system, it is possible to pre-select the suitable

temperature range:

- standard systems 40-80°C

- oor systems 20-45°C.

For further details, consult the “Boiler conguration” section.

Adjusting heating water temperature with an external probe connected

When an external probe is connected, the value of the delivery temperature

is automatically chosen by the system which rapidly adjusts ambient tem-

perature to the changes in external temperature.

To increase or decrease the temperature with respect to the value automa-

tically calculated by the electronic board, turn the heating water selector

clockwise to increase and anticlockwise to decrease.

Adjustment settings range from comfort levels - 5 to + 5 which are indicated

on the digital display when the knob is turned.

Summer mode: turning the selector to the summer mode symbol (g.

28) activates the traditional domestic hot water only function.

ENGLISH

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 di-

splay shows the hot water system temperature, the icon to indicate the hot

water supply and the ame icon (g. 30).

Pre-heating (faster hot water): turning the domestic hot water tempera-

ture adjustment knob to the symbol (g. 31) activates the pre-heating

function. Bring the domestic hot water temperature adjustment knob back

to the required position.

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.

To deactivate the pre-heating function, rotate the domestic hot water tem-

perature 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

to (OFF) (g.32).

Adjustment of the domestic hot water temperature

To adjust the domestic hot water temperature (bathrooms, shower, kitchen,

etc.), turn the knob with the symbol (g. 33) 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 standby status until, after a heat request, the burner switch-

es 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 standby.

If the red LED indicator near the symbol (g. 34) on the control panel

lights up, this means the boiler is in temporary shutdown status (see the

section on “Light signals and faults”).

The digital monitor indicates the fault code detected.

Automatic Temperature Control System function (S.A.R.A.) g. 35

Setting the heating water temperature selector to the area indicated (tem-

perature range 55 to 65°C), activates the automatic temperature control

system (frequency 0.1 sec. on; then 0.1 sec. off; for 0.5 seconds): according

to the temperature set on the room thermostat and the time taken to reach

it, the boiler varies automatically the heating water temperature reducing

the operating time, allowing greater ease of operation and energy saving.

On the control panel, the green LED ashes ON for 0.5 seconds, OFF for

3.5 seconds.

Reset function

To restore operation, set the function selector to (OFF) (g. 32), wait 5-6

seconds then set the function selector to the required position, checking

that the red indicator light is OFF.

At this point the boiler will automatically start and the red lamp switches on

in green.

NOTE: If the attempt to reset the appliance does not activate operation,

contact the Technical Assistance Service.

4.2 Switching off

Temporary switch-off

In case of absence for short periods of time, set the mode selector to

(OFF) (g. 32).

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 mini-

mum output levels to bring the water temperature back to the values for

safety (35°C). During the anti-frost cycle, the symbol (g. 36) appears

on the digital monitor.

Circulator anti-blocking function: an operation cycle is activated every

24 hours.

Switching off for long periods

In case of absence for long periods of time, set the mode selector to

(OFF) (g. 32). Turn the main system switch OFF. Close the fuel 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.

To restore operation (deactivate alarms):

Faults A 01-02-03

Position the function selector to (OFF) (g. 32), wait 5-6 seconds then

set it to the required position (summer mode) or (winter mode).

If the reset attempts do not reactivate the boiler, contact the Technical As-

sistance Centre.

Fault A 04

In addition to the fault code, the digital display shows the symbol .

Check the pressure value indicated by the water gauge: if it is less than 0.3

bar, position the function selector to (OFF) (g. 32) and adjust the lling

tap until the pressure reaches a value between 1 and 1.5 bar. Then position

the mode selector to the desired position (summer) or (winter).

The boiler will perform one purge cycle lasting approximately 2 minutes. If

pressure drops are frequent, request the intervention of the Technical As-

sistance Service.

Fault A 06

The boiler operates normally but cannot reliably maintain a constant do-

mestic hot water temperature, which remains set at around 50°C. Contact

the Technical Assistance Centre.

Fault A 07 - A 08

Contact the Technical Assistance Centre.

Fault A 09 with xed red LED lit

Position the function selector to (OFF) (g. 32), wait 5-6 seconds then

attempts do not reactivate the boiler, request the intervention of the Techni-

cal Assistance Service.

Fault A 09 with ashing red and green LEDs

The boiler is equipped with an auto-diagnostic system which, based on the

total number of hours in certain operating conditions, can signal the need

to clean the primary exchanger (alarm code 09 with ashing red and green

LEDs and ue gas meter >2.500). Once the cleaning operation has been

completed, using the special kit supplied as an accessory, the total hour

meter will need to be reset to zero as follows:

- switch off the power supply

- remove the housing

- loosen the xing screw then turn the instrument panel

- loosen the xing screws on the cover (F) to access the terminal board

(g. 16)

- while the boiler is powered up, using a small screwdriver included, press

the CO button (g. 26) for at least 4 seconds, to check the meter has

been reset, power down then power up the boiler; the meter reading is

shown on the monitor after the “-C-” sign.

Live electrical parts (230 V AC).

NOTE: the meter resetting procedure should be carried out after each

in-depth cleaning of the primary exchanger or if this latter is replaced. To

check the status of the total hour meter, multiply the reading by 100 (e.g.

reading of 18 = 1800 total hours; reading of 1 = 100 total hours).

The boiler continues to operate normally even when the alarm is activated.

4.4 Alarm records

The “ALARM RECORDS” function starts automatically once the display has

been on for 2 hours, or immediately by setting the P1 parameter to 1.

The records include all the latest alarms, up to a maximum of 5 alarms, and

they are displayed in sequence by pushing and releasing the P1 button on

the display board. If the records are empty (P0=0) or if tracking the same is

disabled (P1=0), the display function is not available. Alarms are displayed

in reverse order compared to the order in which they occurred: this means

that the last alarm generated is the rst to be displayed. To delete the

alarms records, simply set parameter P0 to 0.

NOTE: To get to the P1 button the cover on the control panel must be remo-

ved and the display board must be identied (g. 37a).

PROGRAMMING PARAMETERS

Functioning of the display can be personalised by programming three pa-

rameters:

Param. Default Description

P0 0 Deletion of alarms records

(0 = records empty / 1 = records not empty)

P1 0

Immediate activation of alarm record management

(0 = delayed records management activated / 1 =

immediate records management activated

P2 0 Do not change

When button P1 on the display (g. 37a) is held down for at least 10 sec,

the programming procedure is activated. The three parameters, with their

respective values, are shown in rotation on the display (g. 37b). To edit a

parameter value, simply push the P1 button again when the required para-

meter is displayed, and then hold it down until the value switches from 0 to

1 or vice-versa (approx. 2 sec).

The programming procedure is closed automatically after 5 minutes, or if

there is an electrical power failure.

4.5 Boiler conguration

There is a series of jumpers (JPX) available on the electronic board which

enable the boiler to be congured.

To access the board, proceed as follows:

- turn off the main switch on the system

- loosen the xing screws on the housing, move the base of the housing

forwards and then upwards to unhook it from the chassis

- undo the xing screws (E) from the instrument panel (g. 14)

- loosen the screws (F - g. 16) to remove the cover of the terminal board

(230V).

JP8 Do not use

4.6 Setting the thermoregulation (g. 44 - graphs 1-2-3)

The thermoregulation only operates with the external sensor connected;

once installed, connect the external sensor (accessory available on re-

quest) to the special terminals provided on the boiler terminal board.

This enables the THERMOREGULATION function.

Selecting the compensation curve

The compensation curve for heating maintains a theoretical temperature of

20°C indoors, when the external temperature is between +20°C and -20°C.

The choice of the curve depends on the minimum external temperature

envisaged (and therefore on the geographical location), and on the delivery

temperature envisaged (and therefore on the type of system). It is carefully

calculated by the installer on the basis of the following formula:

envisaged delivery T. - Tshift

KT=

20- min. envisaged external T.

Tshift = 30°C standard installations

25°C oor installations

If the calculation produces an intermediate value between two curves, you

are advised to choose the compensation curve nearest the value obtained.

Example: if the value obtained from the calculation is 1,3 this is between

curve 1 and curve 1,5. Choose the nearest curve, i.e. 1,5.

Select the KT using trimmer P3 on the board (see multiwire wiring diagram).

To access P3:

- remove the housing,

- loosen the xing screw on the instrument panel

- turn the instrument panel towards you

- loosen the xing screws on the terminal board cover

- unhook the board casing

Live electrical parts (230 V AC).

The KT values which can be set are as follows:

standard installation: 1,0-1,5-2,0-2,5-3,0

oor installation 0,2-0,4-0,6-0,8

and these are displayed for approximately 3 seconds after rotation of the

trimmer P3.

TYPE OF HEAT REQUEST

Boiler connected to room thermostat (JUMPER JP6 not inserted)

The heat request is made by the closure of the room thermostat contact,

while the opening of the contact produces a switch-off. The delivery tem-

perature is automatically calculated by the boiler, although the user may

modify the boiler settings. Using the interface to modify the HEATING, you

will not have the HEATING SET-POINT value available, but a value that you

can set as preferred between 15 and 25°C. The modication of this value

will not directly modify the delivery temperature, but will automatically affect

the calculation that determines the value of that temperature, altering the

reference temperature in the system (0 = 20°C).

Boiler connected to a programmable timer (JUMPER JP6 inserted)

With the contact closed, the heat request is made by the delivery sensor, on

the basis of the external temperature, to obtain a nominal indoor tempera-

ture on DAY level (20°C). With the contact open, the boiler is not switched

off, but the weather curve is reduced (parallel shift) to NIGHT level (16°C).

This activates the night-time function. The delivery temperature is automati-

cally calculated by the boiler, although the user may modify the boiler set-

tings. Using the interface to modify the HEATING, you will not have the

HEATING SET-POINT value available, but a value that you can set as pre-

ferred between 25 and 15°C. The modication of this value will not directly

modify the delivery temperature, but will automatically affect the calcula-

tion that determines the value of that temperature, altering the reference

temperature in the system (0 = 20°C for DAY level, and 16°C for NIGHT

level).

4.7 Adjustments

The boiler has already been adjusted by the manufacturer during produc-

tion. If the adjustments need to be made again, for example after extraordi-

nary maintenance, replacement of the gas valve, or conversion from meth-

ane gas to LPG, observe the following procedures.

The adjustment of the maximum and minimum output, and of the maximum

and minimum heating and of slow switch-on, must be made strictly in the

sequence indicated, and only by qualied personnel only:

- disconnect the boiler from the power supply

- turn the heating water temperature selector to its maximum

- loosen the xing screws (E) on the instrument panel (g. 14)

- lift then turn the instrument panel towards you

- loosen the xing screws on the cover (F) to access the terminal board

(g. 16)

- insert the jumpers JP1 and JP3 (g. 40)

- power up the boiler.

The three LEDs on the instrument panel ash simultaneously and the dis-

play shows “ADJ” for approximately 4 seconds.

Next change the following parameters:

1. Domestic hot water/absolute maximum

2. Minimum

3. Heating maximum

4. Slow switch-on

as follows:

- turn the heating water temperature selector to set the required value

- press the CO button using a small screwdriver included (g. 26) and then

skip to the calibration of the next parameter.

Live electrical parts (230 V AC).

The following icons light up on the monitor:

1. during domestic hot water/absolute maximum calibration

2. during minimum calibration

3. during heating maximum calibration

4. during slow switch-on calibration

End the procedure by removing jumpers JP1 and JP3 to store these set val-

ues in the memory. The function can be ended at any time without storing

the set values in the memory and retaining the original values as follows:

- remove jumpers JP1 and JP3 before all 4 parameters have been set

- set the function selector to (OFF/RESET)

- cut the power supply 15 minutes after it is connected.

Calibration can be carried out without powering up the boiler.

By turning the heating selection knob, the monitor automatically

shows the number of rotations, expressed in hundreds (e.g. 25 =

2.500 rpm).

The function for visualizing the setting parameters is activated by the func-

tion selector in summer and in winter, by pressing the CO button on the

circuit board, either with or without request for heat. This function cannot be

activated when connected to a remote control. Upon activating the function

the setting parameters are visualized in the order given below, each for 2

seconds. Each parameter is displayed together with its corresponding icon

and fan rotation speed measured in hundreds.

1. Maximum

2. Minimum

3. Max. heating

4. Slow ignition

5. Max. preset heating

GAS VALVE CALIBRATION

- Connect the boiler to the power supply

- Open the gas tap

- Set the function selector to (OFF/RESET) (monitor off)

- Loosen the xing screws on the cover (F) to access the terminal board

(g. 16)

- Using a small screwdriver included, press the CO button (g. 26)

Live electrical parts (230 V AC).

- Wait for burner ignition.

The display shows “ACO” and the yellow LED ashes. The boiler oper-

ates at maximum heat output.

The “combustion analysis” function remains active for a limited time (15

min); if a delivery temperature of 90°C is reached, the burner is switched

off. It will be switched back on when this temperature drops below 78°C.

- Insert the analyser probe in the ports provided in the air distribution box,

after removing the screws from the cover (g. 41)

- Press the “combustion analysis” button a second time to reach the num-

ber of rotations corresponding to the maximum domestic hot water output

4.8 Gas conversion (g. 42-43)

Gas conversion from one family of gases to another can also be easily

performed when the boiler is installed.

This operation must be carried out by professionally qualied personnel.

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

product label.

It is possible to convert the boiler to propane gas, using the special kit.

For disassembly, refer to the instructions below:

- switch off the power supply to the boiler and close the gas tap

- remove in sequence: housing and air distribution box cover

- remove the xing screw from the instrument panel

- unhook and turn the instrument panel forwards

- remove the gas valve (A)

- remove the nozzle (B) inside the gas valve and replace it with the nozzle

from the kit

- ret the gas valve

- remove the silencer from the mixer

- open the two half-shells by prising apart the corresponding hooks (C)

- replace the air diaphragm (D) in the silencer

- ret the air distribution box cover

- re-power the boiler and turn on the gas tap

Adjust the boiler as described in the chapter entitled “Adjustments” with

reference to the information on LPG.

Conversion must be carried out by qualied personnel.

Once the conversion is complete, afx the new identication

label supplied in the kit.

4.9 Checking the combustion parameters

To carry out the combustion analysis, proceed as follows:

- set the main switch of the installation to the “OFF” position

Method 1 - frontal procedure

- turn the selector to position - chimney sweep function

Method 2 - board procedure

- loosen the xing screws (D) on the housing (g. 13)

- move the base of the housing forwards and then upwards to unhook it

from the chassis

- loosen the xing screws (E) on the instrument panel (g. 14)

- lift then turn the instrument panel towards you

- loosen the xing screws on the cover (F) to access the terminal board

(g. 16)

- using a small screwdriver included, press the CO button (g. 26)

Live electrical parts (230 V AC).

For both methods

- Wait for burner ignition. The display shows “ACO”, the yellow LED ash-

es and the boiler operates at maximum heat output.

- Insert the analyser probe in the ports provided in the air distribution box,

after removing the screws from the cover (g. 41).

- Check that the CO2values match those given in the table, if the value

shown is different, change it as indicated in the chapter entitled “Gas

valve calibration”.

- Perform the combustion check.

Then:

- remove the analyser probe and close the sockets for combustion analy-

sis with the special screw

- close the instrument panel and ret the housing.

The ue gas analysis probe must be fully inserted as far as pos-

sible.

IMPORTANT

Even during the combustion analysis phase, the function that switches the

boiler off when the water temperature reaches the maximum limit (about

90°C) remains enabled.

5 MAINTENANCE

The appliance must be systematically controlled at regular intervals to

make sure it works correctly and efciently and conforms to legislative pro-

visions in force.

The frequency of controls depends on the conditions of installation and

usage, it being anyhow necessary to have a complete check carried out by

authorized personnel from the Servicing Centre every year.

- Check and compare the boiler’s performance with the relative specica-

tions. Any cause of visible deterioration must be immediately identied

and eliminated.

- Closely inspect the boiler for signs of damages or deterioration, particu-

larly with the drainage and aspiration system and electrical apparatus.

- Check and adjust – where necessary – all the burner’s parameters.

- Check and adjust – where necessary – the system’s pressure.

- Analyze combustion. Compare results with the product’s specication.

Any loss in performance must be identied and corrected by nding and

eliminating the cause.

- Make sure the main heat exchanger is clean and free of any residuals or

obstruction; if necessary clean it.

- Check and clean – where necessary – the condensation tray to make

sure it works properly.

After routine and extraordinary maintenance operations have

been carried out, ll the siphon, following the instructions in the

section “Switching on the appliance”.

IMPORTANT: always switch off the power to the appliance and close the

gas by the gas cock on the boiler before carrying out any maintenance and

cleaning jobs on the boiler.

Do not clean the appliance or any latter part with ammable substances

(e.g. petrol, alcohol, etc.).

Do not clean panelling, enamelled and plastic parts with paint solvents.

Panels must be cleaned with ordinary soap and water only.

BURNER CLEANING

The ame side of the burner is made with an innovative material of the

latest generation.

- Be especially careful during the dismantling, handling and installation of

the burner and the components next to it (e.g.. electrodes, insulation pa-

nels, etc.)

- Avoid direct contact with any cleaning device (e.g. brushes, vacuum cle-

aners, blowers, etc.).

In general, the burner does not require maintenance, but particular cases

may occur where cleaning is necessary (e.g.. distribution network of gas

containing solid particles and in the absence of a lter on the line, suction

air containing excessively adhesive particulates, etc.).

For this reason, perform a visual control of the burner in order to ensure the

proper functioning of the product:

- remove the front cover of the air box

- unscrew the fastening nut of the gas train to the valve, remove the gas

train spring clip to the mixer and turn the gas train outwards

- remove the silencer from the mixer

- disconnect the connectors of the wiring from the fan and the connecting

cables of the electrodes

- unscrew the xing screws and remove the exchanger-fan cover assem-

bly from its seat

- unscrew the xing screws and remove the burner from its seat checking

it condition.

If necessary, clean the burner with compressed air, blowing

from the metal side of the burner.

It is possible that with ageing, the bres constituting the ame

side of the burner can tone the colour.

- Reassemble everything in reverse order

If necessary, proceed with the replacement of the sealing gas-

kets.

The manufacturer declines all responsibility for any damage caused from

the failure to observe that stated above.

1a GENERAL WARNINGS AND SAFETY

The instruction manual is an integral part of the product and it must there-

fore 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 opera-

tions must be carried out by qualied personnel according to the

provisions of local legislation.

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 installation, calibra-

tion, maintenance or due to improper use.

The safety and automatic adjustment devices must not be modied,

during the system life cycle, by the manufacturer or supplier.

This appliance produces hot water, therefore it must be connected

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. If there is a risk of frost,

drain the boiler.

From time to time check that the operating pressure of the hydraulic

system does not go below 1 bar.

In case of failure and/or malfunctioning, deactivate the appliance,

and do not try to repair or operate directly on it.

Appliance maintenance must be carried out at least once a year:

scheduling it with the Technical Assistance Service will avoid wasting

time and money.

When the product reaches the end of its life it should not be disposed

of as solid urban waste but should be brought to a separated waste

collection facility

Boiler use requires strict observation of 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 when barefoot.

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 use electrical switches, telephone or any other object that

causes sparks if there is a smell of gas. Ventilate the room by open-

ing doors and windows and close the central gas tap.

Do not place anything in the boiler.

Do not perform any cleaning operation if the appliance is not discon-

nected from the mains power supply.

Do not cover or reduce ventilation opening of the room where the

generator is installed.

Do not leave containers and inammable products in the installation

room.

Do not attempt to repair the appliance in case of failure and/or mal-

functioning.

It is dangerous to pull or twist the electric cables.

Children or unskilled persons must not use the appliance.

Do not carry out operations on sealed elements.

For better use, remember that:

- periodic external cleaning with soapy water not only improves its appear-

ance but also preserves panelling from corrosion, extending its life cycle;

- if the wall-mounted boiler is enclosed in a hanging unit, leave at least 5

cm for ventilation and maintenance;

- installation of a room thermostat will greatly improve comfort, a more ra-

tional use of the heat and energy saving; the boiler can also be connected

to a programmable timer in order to control the switching on and off of the

appliance during the day or week.

2a SWITCHING ON THE APPLIANCE

Every time the appliance is powered up, a series of data is shown on the

display including the ue gas sensor meter reading (-C- XX) (see paragraph

4a - “fault A09”); the automatic purge cycle then starts, lasting around 2

minutes. During this phase, the three LEDs light up alternately and the sym-

bol is shown on the monitor (g. 25).
