FUMES EXHAUSTION

AND BURNING AIR SUCTION (C.A.I.-R.A.I.)

Boiler is equipped with a system controlling proper exhaustion of combustion products - fume thermostat (12, fig. 82a-82b page 91-

92); in case of abnormality, this system immediately stops appliance operation. Press the button to restore functionning condition. If abnormality persists, do not perform any action, but immediately call Technical Service; technicians will correct fume exhaustion defect and test operation.

Refer to regulations in force for burnt product exhaustion. It is compulsory using rigid pipes, junctions between elements must

be tight and all components must be resistant to temperature, condensates and mechanical stresses.

Device controlling proper fume exhaustion must never be deactivated. Use original spare parts only when replacing it.

Exhaustion ducts which are not insulated can be dangerous. Openings for burning air must comply with regulations in force. If condensates are produced, insulate exhaustion duct. Fig. 6b shows the top view of boiler with reference measures

for fume outlet distance between centres, from boiler support plate.

Support plate and integrated pre-installation template are provided for with the boiler (fig. 2). Mounting instructions:

• fix the boiler support plate (F) with the template (G) to the wall

and use a plumb to check that it is perfectly horizontal

• trace out 4 holes (Ø 6 mm) for fixing the boiler support plate (F) and 2 holes (Ø 4 mm) for fixing the pre-installation template (G)

• make sure all the measurements are correct, then drill holes in the wall using a drill and point with the diameter given previously

• fix the plate to the wall by the supplied anchor screws

• make hydraulic connections.

After installing the boiler, the screws D

(fig. 3a) can be removed.

After installing the boiler and connecting it to the water and gas supplies, fit the lower cover (A-B, fig. 3b) so that its hooks slip into the relative slots in the lower part of the boiler. Fix the lower cover with the screw C (fig. 3c) contained in the documentation envelope in the boiler.

Before connecting appliance to gas pipe network, check the following:

• regulations in force are met

• gas type used is the same as set for appliance operation

• pipes are clean.

Gas must be piped externally. If the pipe goes through a wall it must go through the central opening in the lower part of the template. It is recommended to install an appropriately sized filter on the gas line in case gas from the mains contains some small solid particles. After installation make sure that all the joints have been made airtight conforming to standard installation practices.

GAS CONNECTION

Position and dimensions of hydraulic connections are specified in

figure 2: A - CH return 3/4” B - CH delivery 3/4” C - gas connection 3/4” D - DHW outlet 1/2” (C.A.I.-MIX C.S.I. only) E - DHW inlet 1/2” (C.A.I.-MIX C.S.I. only) F - Support plate G - Pre-installation template

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

HYDRAULIC CONNECTIONS

To access the electrical connections, proceed as follows:

- unscrew the lower cover fixing screw (C, fig. 3c)

- pull the cover towards you and remove (A-B) (fig. 4a)

- loosen the fixing screws (D) and remove the shell (fig. 3a)

- lift up the panel and turn it forwards

- open the terminal board covers making them slide in the direction of the arrows (fig. 4b: E high voltage connections 230 V, F low voltage connections, G water tank sensor connections only MIX R.S.I.-R.A.I.).

Connect the appliance to the mains power supply with a switch featuring a distance of at least 3,5 mm (EN 60335-1, category III) between each wire. The appliance uses alternating current at 230 Volt/50 Hz, has a power input of 85 W (C.A.I.-R.A.I.), 120 W (26kW MIX C.S.I.), 150 W (30kW MIX C.S.I.-MIX R.S.I.) and 160 W (35kW MIX C.S.I.-MIX R.S.I.) and complies with EN 60335-1 standard. Connect the boiler to a safe earth circuit according to current legislation.

Live and neutral (L-N) connections should also be respected. The boiler can operate with phase-neutral or phase-phase power

supply. For floating power supply, without an earth-bonded conductor, it is necessary to use an insulation transformer with secondary anchored to ground.

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

ELECTRIC CONNECTION

The central heating system can be filled up once the water mains have been connected up. This must be done while the installation is cold by:

• giving two or three turns to the cap of the automatic air vent

valve (A, fig. 5a and 5b) to open it;

• making sure the cold water inlet tap is open (MIX C.S.I. - C.A.I. only)

• opening the filling tap (C, on the boiler for MIX C.S.I. - C.A.I., external for MIX R.S.I. - R.A.I.) until the pressure on the hydrometer (D) is between 1 and 1,5 bar (blue zone) (fig. 5a and 5b).

Close the filling tap after filling it up. The boiler is equipped with an efficient air separator so that there is no need to do anything manually. The burner only ignites when air venting has finished.

NOTE (MIX C.S.I. - C.A.I. only): even if the boiler is fitted with a semi-automatic filling system, open tap C to fill the circuit the first time.

NOTE (MIX R.S.I. - R.A.I. only): manual filling tap is not supplied with the boiler, foresee one external or verify if external water tank has one.

Empty the system by:

• switching off the boiler

• connect the rubber hose, supplied standard, to the boiler drain valve (E, fig. 5a and 5b)

• loosening the valve by hand (E)

• emptying out the lowest parts of the system.

DHW system emptying (MIX C.S.I. - C.A.I. only)

The hot water system must be emptied every time there is risk of freezing by:

• turning off the tap at the mains

• turning on all the hot and cold taps

• emptying out the lowest parts of the system.

ATTENTION

The safety valve outlet (B) must be connected to a suitable collection system. The manufacturer shall not be held liable if the safety valve should eventually cause flooding.

FILLING AND EMPTYING THE SYSTEM

Gas and/or water pipes may not be used to earth electrical equipment.

The installer is responsible for making sure that the appliance has an adequate earthing system; the manufacturer shall not be held liable for eventual damages caused by incorrect usage or failing to earth the boiler.

Use the supplied power cable to connect the boiler to the mains power supply. Connect the ambient thermostat and/or time clock as shown in the electrical diagram on page 100.

When replacing the power cable, use a HAR H05V2V2-F cable, 3 x 0,75 mm

, Ø max. external 7 mm.

Refer to regulations in force for exhaustion of combustion products. Boiler is provided for without fume exhaustion/air suction kit, since forced draught sealed chamber accessories can be used, as they better adapt to installation characteristics. For fume extraction and burning air restoration in boiler, use original pipes or other EC-certified pipes with equivalent characteristics; check connection is correct as shown on instructions fume accessories provided for with. More appliances can be connected to a single chimney, provided that all appliances are sealed chamber type. Boiler is a C-type appliance (sealed chamber) and must be safely connected to fume exhaustion duct and burning air suction duct, both getting outside; appliance cannot operate without these ducts.

Concentric outlets (ø 60-100)

Concentric ducts may be placed in the most suitable direction for installation requirements but special care must be taken as regards the external temperature and the length of the duct. Consult the graphs to find out whether a condensate collector is required.

Twin outlets (ø 80)

Twin ducts can be placed in the most suitable direction for installation requirements but special care must be taken as regards the temperature of the installation site and the length of the fumes duct. To install, follow the instructions supplied with the kit.

In the event of installation with external discharge sections, to calculate the maximum permitted length without a condensate collector, refer to the external temperature instead of that of the installation site of the boiler.

If the appliance works at temperatures lower than 50°C (e.g.: installations with external probe), the maximum permitted length without condensate collector must be decreased by

0.85 metres. The condensate collector can only be applied to the fumes

outlet, within 0.85 m from the boiler; connect the trap of the condensate collector to a waste water drain.

The fumes outlet duct must slope by 1% towards the condensate collector.

The boiler automatically adapts ventilation according to the type of installation and the length of the ducts. Do not obstruct or narrow the ducts in any way.

If the length of the ducts is different from that indicated in the table to the side:

- for model 26 MIX C.S.I., the sum of the lengths of the inlet and outlet ducts must be less than 30 metres, but the length of a single duct must not exceed 18 metres

- for models 30 MIX C.S.I. - MIX R.S.I., the sum of the lengths of the inlet and outlet ducts must be less than 28 metres, but the length of a single duct must not exceed 17 metres

- for model 35 MIX C.S.I. - MIX R.S.I., the sum of the lengths of the inlet and outlet ducts must be less than 12 metres, but the length of a single duct must not exceed 8 metres.

Adjusting heating water temperature

Turning the selector A (fig. 18), after having positioned the selector mode on winter

or winter comfort , it is possible to regulate

the heating water temperature.

Turn clockwise to increase the temperature and anticlockwise to decrease. The bar segments light up (every 5°C) as the temperature is increased. The selected temperature value appears on the display. If you enter the S.A.R.A. adjustment field (from 55 to 65 °C)

while selecting the heating water temperature, the symbol

and

the graduated scale start flashing. For details about the S.A.R.A. function, read page 14. The selected temperature value appears on the display.

Adjusting heating water temperature with an external sensor connected

When an external probe is connected, the value of the delivery temperature is automatically chosen by the system which rapidly adjusts ambient temperature to the changes in external temperature. Just the central segment of the bar is illuminated (fig. 19). To increase or decrease the temperature with respect to the value automatically calculated by the electronic board, turn the heating water selector clockwise to increase and anticlockwise to decrease. The bar segments light up (at every comfort level), correction tolerance lies between - 5 and + 5 comfort levels (fig. 19). When choosing the level of comfort, the digit area of the display shows the required level of comfort while the bar shows the matching segment (fig. 20).

Adjusting domestic hot water temperature

To adjust domestic hot water temperature, turn switch B (fig. 21) clockwise to increase and anticlockwise to decrease. The bar segments light up (every 3°C) as the temperature is increased.

The selected temperature value appears on the display. When choosing the temperature, both for heating and domestic hot water, the display shows the value being selected. About 4 seconds after the selection has been made, the modification is memorised and the display returns to the delivery temperature read by the probe.

Switching on

Switch on the boiler as follows:

- access the gas tap through the slots in the cover located in the lower part of the boiler

- open the gas tap by turning it anti-clockwise (fig. 15)

- power the boiler.

When powered, the boiler performs a test sequence and a series of numbers and letters are shown on the display. If the test is successful the boiler is ready to work about 4 seconds after the cycle ends. The display will look like fig. 16.

If the test is unsuccessful, the boiler will not work and a “0” will flash on the display. In this case, contact the Technical Assistance Centre.

The boiler turns on in the status it was in before it was switched off: if the boiler was in the winter comfort mode when it was switched off, it will turn on again in the winter comfort mode. If it was in the OFF mode, the display will show two segments in the

central area (fig. 17). Press the

button to enable operation.

- press the function selector until the indicator moves to the required function

, depending on the kind of operation chosen.

- WINTER

: with the selector in this position, the heating water

and domestic hot water functions are activated. In this position the S.A.R.A. function is enabled in the heating mode (see chapter “Boiler functions”). The boiler actives the temperature stabiliser in order to ensure the continuous production of domestic hot water, even for small demands or when the inlet water is already hot. This prevents temperature oscillations due to the burner switching off/on.

- WINTER COMFORT

: with the selector in this position, as well as the traditional function of heating water and domestic hot water, the preheating function is also activated which keeps the water in the domestic hot water exchanger hot in order to reduce waiting times. The S.A.R.A. Booster and Domestic hot water preheating functions are enabled in this position (see chapter “Boiler functions”).

- SUMMER

: with the selector in this position, just the traditional

domestic hot water function is activated.

- SUMMER COMFORT

: with the selector in this position, the

boiler provides just domestic hot water with a temperature stabiliser for small deliveries. Ideal at the times of year or in the areas where the mains water is already warm. In these conditions, the temperature of the hot water produced by a boiler with just traditional functions (see SUMMER and WINTER COMFORT) may be instable.

If this condition occurs it means that the system is incorrectly pressurised though the boiler will continue to work regularly. Press the circuit filling button

to start-up the filling sequence.

Press the circuit filling button

a second time to interrupt the filling sequence. During filling, the drops of the circuit filling symbol

and the growing pressure value appear on the

display in a cascade sequence (fig. 27).

After filling, the

symbol is displayed for a few moments and then

turns off.

Note

During filling, the boiler does not perform other functions. For example, if there is a request for domestic hot water, the boiler is unable to provide it until filling has finished.

Note

If circuit pressure reaches 0.6 bar, the pressure value flashes on the display (fig. 28b); if it falls below a minimum safety value (0.3 bar), fault code 41 appears on the display (fig. 28a) for a certain time, following which, if the fault persists, fault code 40 is displayed (see chapter on “Troubleshooting”).

In the event of fault 40, press

to reset and then to start filling the circuit. If you have to fill the system several times, contact the Technical Service Centre to check whether the heating circuit is watertight (see if there are any leaks).

Information

Press

, the display turns off and just the word InFO appears (fig.

29). Press the button

to view operating information. Press the button again to move on to the next piece of information. If the button is not pressed, the system automatically exits the function.

Info list: Info 0 shows the word InFO (fig. 29)

Info 1 only with the external probe connected, displays external

temperature (e.g. 12 °C) (fig. 30). The values shown on the display range between - 40 °C and 40 °C. Beyond these values the display shows “- -”

Fig. 27

Working the boiler

Adjust the ambient thermostat to the required temperature (approx. 20 °C). If there is a demand for heating water, the boiler starts

and the

symbol is shown on the display (fig. 22). The boiler will remain working until the set temperatures are reached, after which it will go on stand-by. In the event of ignition or operating faults, the boiler will perform a “safety stop”.

The flame symbol

will go out and the fault code and will

be displayed (fig. 23). For a description of faults and how to reset them, consult chapter “Troubleshooting”.

Switching off

Switching off for short periods

For brief absences press the

button to switch off the boiler. The

display will show two segments in the central area (fig. 17). When the boiler remains powered with the gas tap open, it is protected by the following systems:

- anti-freeze (fig. 24): when the temperature of the water in the

boiler falls below safety values, the circulator and the burner work at minimum power to increase the water temperature to a safe value (35 °C). The

symbol lights up on the display.

- circulator anti-block: one operating cycle is performed every

24 hours.

Switching off for long periods

For prolonged absences press the

button to switch off the boiler

(fig. 17). The display will show two segments in the central area. Turn the main switch to “off”. Turn off the gas tap under the boiler by turning it clockwise (fig. 25).

In this case, the anti-freeze and anti-block systems are disabled. Empty the water circuit or suitably protect it with a good make of anti-freeze. Drain the domestic hot water circuit.

S.A.R.A. BOOSTER function

If the “winter comfort” mode is selected, the S.A.R.A. Booster function is activated for the heating circuit and reaches the required ambient temperature more quickly.

DOMESTIC HOT WATER PRE-HEATING function

If the “winter comfort” mode is selected, the domestic hot water Preheating function is enabled. This function sets out to keep the domestic hot water contained in the boiler hot, thereby considerably reducing delivery waiting times.

The

function should be selected to reduce power consumption

in areas where the mains water is not particularly cold. In this case, the Booster and Preheating functions are not activated.

Troubleshooting

When a fault appears on the display, the flame symbol goes out, a flashing code is shown and the two symbols

and

appear either together or separately. For a description of the faults, consult the following table

(D) Permanent (T) Temporary. In this operating status the boiler attempts to eliminate the fault on its own (°) See NOTE in the next page. (*) For the “insufficient circuit pressure” fault, proceed with the circuit filling operations described in the “Boiler functions” chapter.

START-UP AND OPERATION

(R.A.I. - MIX R.S.I.)

This boiler is able to operate in different conditions:

CASE A) only heating CASE B) only heating with external water tank connected,

managed by a thermostat, to prepare domestic hot water

CASE C) only heating with external water tank connected,

managed by a temperature sensor (kit available upon request), to prepare domestic hot water.

Depending on the type of installation selected, it is necessary to set the parameter “domestic hot water mode”. This operation must be performed by a Technical Service Centre when starting-up the boiler.

Adjusting heating water temperature

Turning the selector A (fig. 52), after having positioned the selector mode on winter , it is possible to regulate the heating water

temperature.

Adjusting heating water temperature with an external sensor connected

When an external probe is connected, the value of the delivery temperature is automatically chosen by the system which rapidly adjusts ambient temperature to the changes in external temperature. Just the central segment of the bar is illuminated (fig. 53). To increase or decrease the temperature with respect to the value automatically calculated by the electronic board, turn the heating water selector clockwise to increase and anticlockwise to decrease. The bar segments light up (at every comfort level), correction tolerance lies between - 5 and + 5 comfort levels (fig. 53). When choosing the level of comfort, the digit area of the display shows the required level of comfort while the bar shows the matching segment (fig. 54).

Switching on

Switch on the boiler as follows:

- access the gas tap through the slots in the cover located in the lower part of the boiler

- open the gas tap by turning it anti-clockwise (fig. 47)

- power the boiler.

The display will look like fig. 48. If the test is unsuccessful, the boiler will not work and a “0” will flash on the display. In this case, contact the Technical Assistance Centre.

The boiler turns on in the status it was in before it was switched off: if the boiler was in the winter mode when it was switched off, it will turn on again in the winter mode. If it was in the OFF mode, the display will show two segments in the central area (fig. 49).

Press the

button to enable operation.

Choose the desired operating mode by pressing button, until the

symbol moves to:

WINTER

SUMMER

WINTER function (fig. 50)

With the selector in this position, the boiler provides hot water for the heating and, if an external water tank is connected, provides water to the water tank to allow domestic hot water preparation. Function S.A.R.A Booster is enabled in this position (see chapter “Boiler functions”).

SUMMER function (only with external water tank connected, fig. 51)

With the selector in this position, the boiler provides water to the water tank with a temperature stabiliser to allow domestic hot water preparation.

Working the boiler

Adjust the ambient thermostat to the required temperature (approx. 20 °C). If there is a demand for heating water, the boiler starts

and the

symbol is shown on the display (fig. 56). The boiler will remain working until the set temperatures are reached, after which it will go on stand-by. In the event of ignition or operating faults, the boiler will perform a “safety stop”.

The flame symbol

will go out and the fault code and will

be displayed (fig. 57). For a description of faults and how to reset them, consult chapter “Troubleshooting”.

Switching off

Switching off for short periods

For brief absences press the

button to switch off the boiler. The

display will show two segments in the central area (fig. 49). When the boiler remains powered with the gas tap open, it is protected by the following systems:

- anti-freeze (fig. 58): when the temperature of the water in the

boiler falls below safety values, the circulator and the burner work at minimum power to increase the water temperature to a safe value (35 °C). The

symbol lights up on the display.

- circulator anti-block: one operating cycle is performed every

24 hours.

Switching off for long periods

For prolonged absences press the button to switch off the boiler (fig. 49). The display will show two segments in the central area.

Turn the main switch to “off”. Turn off the gas tap under the boiler by turning it clockwise (fig. 59).

In this case, the anti-freeze and anti-block systems are disabled. Empty the water circuit or suitably protect it with a good make of anti-freeze.

CHECKING COMBUSTION PARAMETERS

To ensure the product remains in perfect working order, and to comply with current legislation, systematically check the boiler at regular intervals.

To analyse combustion, proceed as follows:

- access the CALIBRATION & SERVICE phase by setting the password as indicated in chapter “Adjustments”

- turn the domestic hot water temperature selector to maximum heating power (parameter HH).

The boiler works at maximum power for 4 minutes.

C.A.I.-R.A.I.:

- The hole for inserting analysis instruments must be made in the section of straight pipe immediately after it leaves the hood in compliance with current law (A, fig. 81a).

MIX C.S.I.-MIX R.S.I.:

- use appropriate tools on the taps fitted to the air distribution box after removing the cover (B, fig. 81b/c).

The first tap is connected to the air intake circuit and detects infiltration of fumes from concentric outlets; the second is directly connected to the fumes outlet circuit and is used to detect combustion parameters and efficiency.

The fumes analysis probe must be fully inserted.

IMPORTANT: the function that switches off the boiler when water

temperature reaches a maximum of about 90 °C is still enabled during the combustion analysis phase.

murale.

Pour l’évacuation des produits de la combustion consultez les normes en vigueur. La chaudière est vendue sans kit d’évacuation des fumées/ d’aspiration de l’air car vous pouvez utiliser les accessoires pour les appareils à chambre étanche à tirage forcé les mieux adaptés aux caractéristiques de l’installation. Pour extraire les fumées et rétablir l’air comburant de la chaudière il est indispensable d’utiliser des tuyauteries originales et d’effectuer correctement le raccordement, de la façon indiquée par les instructions fournies avec les accessoires pour fumées. Vous pouvez raccorder plusieurs appareils sur un seul conduit de cheminée à condition qu’ils aient tous une chambre étanche. La chaudière est un appareil de type C (à chambre étanche) qui doit avoir un raccordement sûr sur le conduit d’évacuation des fumées et sur celui d’aspiration de l’air comburant, débouchant tous deux à l’extérieur; sans eux l’appareil ne peut pas fonctionner.

Conduits coaxiaux (ø 60-100)

Les conduits coaxiaux peuvent être orientés dans la direction la mieux adaptée aux exigences de l’installation, mais il faut faire très attention à la température extérieure et à la longueur du conduit. Consultez les graphiques pour établir s’il est ou non obligatoire de prévoir un récupérateur de condensats.

En cas de fonctionnement avec une température de la chaudière inférieure à 50°C (par exemple avec ne sonde extérieure), la longueur maximum autorisée doit être réduite d’un mètre.

Prévoyez une inclinaison du conduit d’évacuation des fumées de 1% vers le récupérateur de condensats.
