2 - DESCRIPTION
MySMART C.S.I. is a wall-mounted type C condensation boiler for
heating and the production of domestic hot water. Depending on the
fume discharge accessory used, it is classified in categories B23P;
B53P; C13, C13x; C33, C33x; C43, C43x; C53, C53x; C63, C63x;
C83, C83x; C93, C93x, 3CEP.
In configuration B23P (when installed indoors), the appliance cannot
be installed in bedrooms, bathrooms, showers or where there are
open fireplaces without a proper air flow. The room where the boiler
is installed must have proper ventilation. Detailed regulations for the
installation of the flue, gas piping and ventilation ducting are given in
Standards UNI 7129-7131 and UNI 11071.
In configuration C, the appliance can be installed in any type of room
and there are no limitations due to ventilation conditions or room volume.
It is also possible, using a check valve included as an accessory, to
install the boiler on collective pressurised flues; for the details, see
section 3.12 “Installation on collective flues in positive pressure”.
3 - INSTALLATION
3.1 Installation regulations
Installation must be carried out by qualified personnel in compliance
with local regulations.
POSITION
MySMART C.S.I. is a wall-mounted boiler for heating and for the
production of hot water. There are two categories, depending on the
type of installation:
1. B23P-B53P type boiler - forced open installation, with flue gas
discharge pipe and pick-up of combustion air from the installation area. If the boiler is not installed outdoors, air intake in the
installation area is compulsory.
2. C13, C13x; C33, C33x; C43, C43x; C53, C53x; C63, C63x; C83,
C83x, C93, C93x: appliance with airtight chamber, with flue gas
discharge pipe and pick-up of combustion air from outside.
MySMART C.S.I.
5
It does not require an air intake point in the installation area.
This type MUST be installed using concentric pipes, or other
types of discharge designed for condensation boilers with an airtight chamber.
MINIMUM DISTANCES
In order to have access to the boiler to perform regular maintenance
operations, respect the minimum spaces foreseen for installation
(fig. 1).
For correct appliance positioning:
- do not place it on a cooker or other cooking device
- do not leave inflammable products in the room where the boiler is
installed
- heat sensitive walls (for example, wooden walls) must be protected
with proper insulation.
Preliminary check
- Before installation, wash every system piping carefully in order to
remove any residues that may impair the operation of the appliance.
- Connect the discharge manifold to a suitable discharge system (for
details, refer to chapter 3.8).
- 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 wording on the
packaging and by 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 / 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. anti-freeze liquids, filming agents, etc.) and check
the parameters in the table are within the values indicated.
Parameters Um
Heating
circuit water
Filling water
PH value 7~8 -
Hardness ° F - 15~20
Appearance - clear
3.3 Characteristics of the DHW circuit water
If consumption water has a total hardness between 25° F and 50° F,
install a DHW treatment kit; with a total hardness greater than 50° F,
the kit’s effectiveness progressively reduces and therefore the use of
an appliance of higher performance or total softening is recommended; even with a total hardness of less than 25° F, a filter of appropriate size must be installed if the w
ater comes from the mains that is not
perfectly clean/cleanable.
3.4 Eliminating the air from the heating circuit
and boiler
During the initial installation phase, or in the event of extraordinary
maintenance, you are advised to perform the following sequence of
operations (Fig. 2):
1. Open by two or three turns the automatic relief valve cap (A) and
leave it open.
2. Open the system filling tap located on the water unit.
3. Switch on the electricity supply to the boiler, leaving the gas tap
turned off.
4. Activate a heat request via the ambient thermostat or the remote
control panel, so that the 3-way valve goes into heating mode.
5. Activate a domestic water request as follows: open a tap for 30”
every minute so the 3-way valve passes from heating to domestic water and vice versa about 10 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. Continue the sequence until no more air can be heard coming
from th
e air vent valve.
7. Check the system pressure level is correct (the ideal level is 1 bar).
8. Turn off the system filling tap.
9. Turn on the gas tap and ignite the boiler.
3.5 Positioning the wall-mounted boiler and
hydraulic connections
The boiler is supplied as standard with a boiler support plate with
built-in pre-assembly template (Fig. 3). The position and dimension
of hydraulic fittings are shown in the detail drawing.
For the assembly, proceed as follows:
- secure the boiler support plate (F) using the pre-assembly template
(G) to the wall and use a spirit level to make sure that everything
is perfectly horizontal
- mark the 4 holes (ø 6 mm) envisaged for securing the boiler sup-
port plate (F) and the 2 holes (ø 4 mm) for securing the pre-assembly template (G)
- make sure that all measurements are exact, then drill the wall us-
ing drill tips with the diameters indicated above
- fix the plate with the built-in template to the wall.
- assemble the hydraulic equipment supplied: taps, connections,
straight trains (t
o be shortened if needed), nuts and gaskets (fi g. 3)
The tap with fi lter should be installed on the heating return
line.
The tap with fi lter, unlike the other taps, has a lever with 3 positions: open-
ing - closing and cleaning.
For the cleaning position see paragraph “5.1 Routine maintenance”.
Make the hydraulic connections and then fix the lower cover connections.
The position and size of the hydraulic connections are indicated below:

3.6 Installing the external probe
The correct operation of the external probe, supplied as an accessory, is fundamental for the good operation of the climatic control.
INSTALLING AND CONNECTING THE EXTERNAL PROBE
The probe must be installed on an external wall of the building to be
heated, 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
solar irradiation;
- it must be mounted about 2/3 of the way up the wall;
- it must not be mounted near doors, windows, air outlet points, or
near smoke pipes or other heat sources.

The electrical wiring to the external probe 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 probe. 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 PROBE TO THE WALL
The probe must be placed on a smooth part of the wall (Fig. 4); in the
case of exposed 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 fixing area of the wall, drill the holes for the
5x25 wall plug.
Insert the plug in the hole. Remove the card 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 probe connection cable and connect it to the electric clamp.
To make the electrical connection between the external probe and
the boiler, refer to the “Electrical wiring” chapter.
Remember to close the cable grommet well, to prevent any air
humidity getting in through the opening.
Put the card back in its seat.
Close the plastic upper protective cover by turning it clockwise. Tighten the cable grommet very well.
3.7 Installation of the remote control panel
To correctly check the ambient temperature, the control panel
should be installed in a reference position in the home.
For a correct installation, keep in mind that the panel:
it should be installed on a wall, preferably not a perimeter one,
that has no hot or cold pipes running through it
It should be fi xed about 1.5 m from the ground
It should not be installed near doors or windows, cooking equip-
ment, radiators, fan coils or generally in conditions that might
alter the measured temperatures.

Power up the WiFi Box using the relative cable and power sup-
ply provided as standard.
3.8 Condensate collection
The discharge manifold (Fig. 5) collects condensate water, any evacuation water from the safety valve and the system discharge water.
The manifold must be connected via a rubber pipe (not provid-
ed) to an appropriate collection and evacuation system in the
white water discharge drain in compliance with current regulations. The outer diameter of the manifold is 20 mm: it is there-
fore advisable to use a rubber pipe Ø 18-19 mm closed with a
suitable clamp (not provided).
The manufacturer is not liable for any damage/flooding result-
ing from the failure to channel the condensate.
Sealing of the condensate drainage connection line must be
guaranteed.
3.9 Electrical wiring
To access the electrical wirings, proceed as follows:
To access the terminal board:
- set the system's main switch to off
- undo the fixing screws (D) of the shell (fig. 6)
- move the shell base forward and then upwards to unhook it from
the chassis
- lift and then turn the instrument panel upside down (fig. 7)
- remove the electrical parts inspection cover (fig. 8)
The connection to the mains supply must be made via a separation
device with an omnipolar opening of at least 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 make the connection with a safe ground/earth,
in compliance with current directives.
The installer is responsible for ensuring the appliance is suita-
bly earthed; the manufacturer will not be liable for any damage
resulting from an incorrect or absent earth connection
It is also advisable to respect the phase-neutral connection
(L-N).
The ground/earth wire 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 transfo
rmer with earth-anchored secondary.
It is forbidden to 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 (fig. 9).
3.10 Gas connection
Before connecting the appliance to the gas network, check that:
- current prevailing standards have been met
- the gas type is appropriate for the appliance
- the piping is clean.
The gas pipe must be installed outdoors. If the pipe has to pass
through the wall, it must pass through the central opening in the lower part of the template.
It is advisable to install a filter 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.
3.11 Flue gas exhaustion and air aspiration (fig. 10)
For flue gas discharge, refer to Standards UNI 7129-7131 and UNI
11071. Always comply with local standards of the Fire Department,
the Gas Company and with possible municipal dispositions.
The discharge of flue gas is guaranteed by the centrifugal fan located
inside the combustion chamber. The boiler is supplied without the
flue gas outlet/air suction kit, since it is possible to use the accessories for appliance with a forced draught sealed chamber that better
adapts to the installation characteristics.
It is essential for evacuating fumes and restoring boiler combustion
air that only original Riello pipes be used and that the connection is
made correctly as shown in the instructions provided with the flue
gas accessories.
A single smoke pipe can be connected to several appliances provided that every appliance is the condensing type
The boiler is a C-type appliance (with airtight chamber), and must
therefore have a safe connection to the flue 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.
Both concentric and twin terminals are available.
As envisaged by Standard UNI 11071, the boiler is designed to take
in and dispose of flue gas condensate and/or meteoric water condensate deriving from the flue gas discharge system. It does this via its
own drain-tap, if an external drain-tap is not fitted during the design
or installation phase.
if a condensate relaunch pump is installed, check the technical
data (provided by the manufacturer) regarding output, to ensure it operates correctly.
POSSIBLE OUTLET CONFIGURATIONS (fig. 11)
B23P-B53P - Suction in room, with external outlet.
C13-C13x - Concentric wall outlet. Pipes can leave the boiler inde-
pendently, but the outputs must be concentric or near enough in order to be subjected to similar wind conditions (within 50 cm)
C33-C33x - Concentric roof outlet. Output as C13.
C43-C43x - Discharge and suction in common, separate smoke
pipes, but subjected to similar wind conditions.
C53-C53x - Separate wall or roof outlet and suction line and in areas
with different pressures. Outlet and suction line must never be placed
on opposite walls.
C63-C63x - Outlet and suction line carried out with pipes marketed
and certified separately (1856/1).
C83-C83x - Outlet in single or regular smoke pipe and wall suction
line.
C93-C93x - Discharge on the roof (similar to C33) and air suction
from a single existing smoke pipe.
See the prevailing standards.
“FORCED OPEN” INSTALLATION (TYPE B23P/B53P)

The boilers leave the factory regulated to 6.100 r.p.m. for domestic
hot water and 4.500 r.p.m. for heating and the maximum achievable length is 6 m for the pipe ø 60, 0,5 m for the pipe ø 50 and 35
metres for the pipe ø 80.
If you need to reach greater lengths compensate for the pressure
drop with an increase of the number of fan rotations as shown in the
adjustments table in order to guarantee the rated heat input.
The minimum calibration must not be modified.
If the prevailing value is greater than 200 Pa the law requires the use

3.13 Installation on collective flues in positive
pressure
The collective flue is a gas discharge system suitable for collecting
and expelling the combustion products of several appliances installed on several floors of a building (fig. 18).
The collective flues in positive pressure can be used only for type C
condensing appliances. Consequently the B53P/B23P configuration
is not permitted.
Installation of the boiler on collective flues in pressure is permitted
only at G20 using a specific check valve, supplied as an accessory.
See the related instructions for the assembly procedure.
The boiler is sized to operate correctly up to a maximum internal
pressure of the smoke pipe no higher than the value shown in the
multigas table.
Complete the check valve assembly operations and proceed with
adjustment of the number of fan rotations as shown in the multigas
table.
Ensure that the air suction pipes and combustion product outlet are
airtight.
Installation of the check valve (fig. 19) requires the application of the
ATTENTION label that comes with the same accessory on a visible
part of the boiler shell. Applying the label is essential for safety during
maintenance or replacement of the boiler and/or the collective flue.
WARNINGS
The manufacturer will not be liable in the event of failure to
apply the check valve and the related label prior to placing the
boiler in service.
The appliances connected to a collected flue must all be of the
same type and have equivalent combustion characteristics.
The number of appliances that can be connected to a collective
flue in positive pressure is defined by the smoke pipe designer.
MAINTENANCE FOR APPLICATION IN A COLLECTIVE FLUE
UNDER PRESSURE
During scheduled maintenance on the appliance you must also
check the condition of the check valve in order to guarantee correct
operation and safety of the system.
Before proceeding with maintenance you must conduct an analysis
of the combustion product and check the boiler operating status.
In the event of maintenance on the boiler's combustion circuit
(gas discharge pipes, condensate syphon, burner, electrode
conveyors) you must close the gas discharge pipe that comes
from the smoke pipe under pressure and check the seal.
Subsequently:
- Remove electrical power by setting the system's main switch to
“off”
- Close the gas interception taps
- Remove the shell
- Unhook the instrument panel and rotate it downward
- Unhook and remove the air box cover
- After undoing the related fixing screws, remove the right side of
the air box
- Undo the nut that secures the gas train valve to the air box
- Undo and remove the mixer connection gas train (A, fig. 20)
- Remove the ignition electrode and flame detection electrical con-
nections and the fan electrical connections
- Undo the 4 screws that secure the air gas conveyor to the main
heat exchanger (B, fig. 20)
- Remove the conveyor-fan assembly from the heat exchanger (C,
fig. 20), taking great care not to damage the burner insulating panel
- To access the check valve remove the fan by undoing the 4 screws
(D, fig. 21) that secure it to the conveyor
- Ensure that there is no material deposited on the check valve
membrane and remove any you may find, ensuring there is no
damage.
- Check the correct opening and closing operation of the valve
- Reassemble the components working in reverse order, ensuring
that the check valve is reassembled in the correct direction (see
fig. 21)
Failure to observe the above may lead to abnormal operation
of the check valve and consequent differences in the boiler's
performance, up to failure to operate.
Failure to observe what is described here may compromise the
safety of people and animals due to possible carbon monoxide
leaks from the smoke pipe.
Once the operations have been completed, carefully check all
the combustion product exhaust and air suction pipe seals,
conducting a combustion analysis.
NOTE
If the fan is removed ensure that the check valve is reassembled in
the correct direction (see fig. 21).
3.14 Filling the heating system (fig. 22-23-24)
Once the hydraulic connections have been carried out, fill the heating
system.
This operation must be carried out with a cold system, following
these instructions:
- open the lower automatic relief valve cap (A) by two or three turns
to allow continuous air venting and leave it open
- ensure that the cold water inlet tap is open
- open the filling tap (C) until the pressure indicated on the water
gauge is between 1 bar and 1.5 bar
- re-close the filling tap.
NOTE
deareation of the boiler takes place automatically by means of the
two automatic A and E bleed valves, the former positioned on the
circulator whereas the latter is positioned inside the air box. If the
deareation phase is difficult, operate as described in section 5.3.
3.15 Emptying the heating system
Before starting emptying, switch off the electricity supply by turning
off the main switch of the system.
- Close the heating system shut-off devices
- Slacken the discharge system valve by hand (D)
- The system's water is discharged through the discharge manifold (F).
The discharge manifold must be connected via a rubber pipe
to an appropriate collection and evacuation system in the white
water discharge drain in compliance with current regulations.
The outer diameter of the manifold is 20 mm: it is therefore advisable to use a rubber pipe Ø18-19 mm closed with a suitable
clamp (not provided).
3.16 Emptying the domestic hot water circuit
When there is risk of frost, the domestic hot water system must be
emptied in the following way:
- close the water mains tap
- open all the hot and cold water taps
- empty the lowest points.
3.17 Cover connections
The installation completed, it is possible to apply the cover connections as shown below:
- position the cover connections so that the lateral slots are in cor-
respondence with the holes (A) present on the bracket
- using anchor bolts supplied, secure from the inside the cover to
the shell.
Do not tighten the pins in the bottom, but leave a suffi cient space
to allow the cover to rotate.
- rotate upwards and slide the cover towards the wall till the limit
To open the cover connections act as described below:
- press cover by releasing the hooks (B) that hold it in place pull it
towards you
- push it down.
In this way you have the full access to the taps and fi ttings.

4 - IGNITION AND OPERATION
4.1 Preliminary checks
When the boiler is first started the siphon for collecting the con-
densate is empty.
It is therefore necessary to create a head of water fi lling the siphon
before starting up, following these instructions:
- remove the siphon by releasing it from the plastic pipe connecting
to the combustion chamber
- fi ll the siphon about 3/4” full with water, making sure it is free of
any impurities
- check the fl 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 fi rst creating the head of water in the siphon.
Repeat this operation during routine and extraordinary maintenance
operations.
First ignition is carried out by competent personnel from an authorised Technical Assistance Service Centre.
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 flue 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) the correct calibration of the gas valve and, if necessary, adjust
as indicated in paragraph 4.7 “Adjustments”
h) that the fuel supply system is sized to provide the correct deliv-
ery to the boiler, and that it has all the safety and control devices
prescribed by national and local regulations.
4.2 Appliance ignition
Each time the boiler is electrically powered the display shows a series of information including the gas probe counter value (-C- XX)
(see section 4.4 - fault A09) and then the boiler begins an automatic
venting cycle that lasts about 2 minutes. During this phase the symbol
will appear on the display (fig. 25).
To interrupt the automatic venting cycle: access the electronic card
by removing the shell, turning the instrument panel upside down and
opening the electrical parts inspection cover. Subsequently:
- press the CO button (fig. 26).
Live electrical parts (230 Vac).
To start-up the boiler it is necessary to carry out the following operations:
- electrically power the boiler
- unhook the connections cover as indicated in section 3.16 “Con-
nections cover”
- open the gas tap to allow fuel flow
- set the ambient thermostat at the required temperature (~20°C)
- turn the mode selector to the desired position:
Winter
Turning the mode selector (fig. 27) within the area marked with + and
- the boiler provides domestic hot water and heating.
The boiler lights automatically in response to a heat request.
The digital monitor indicates the heating water temperature (fig. 28).
In the event of a request for domestic hot water.
The display indicates the domestic hot water temperature (fig. 29).
Adjusting the heating water temperature
To adjust the heating water temperature, turn the knob with the “
” symbol (fig. 27) clockwise to the area marked with + and -.
Depending on the type of system, the most suitable temperature
range can be pre-selected:
- standard installations 40-80°C
- floor installations 20-45 °C.
For details see section 4.5.
Summer
Turning the selector to the
summer symbol (fig. 30) the traditional
function of only domestic hot water is activated.
The boiler lights automatically in response to a request for domestic
hot water.
The digital monitor indicates the domestic hot water temperature
(fig.29).
Pre-heating (faster hot water)
Positioning the mode selector to summer or winter and turning the
domestic hot water temperature adjustment knob to the
symbol
(fig. 31) the pre-heating function is activated. 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.
The display indicates the outlet temperature of the heating water or
the domestic hot water based upon the request in progress.
During burner ignition following a pre-heating request, the monitor
indicates the
symbol.
To deactivate the pre-heating function, rotate the domestic hot water
temperature adjustment knob back to the symbol
.
Bring the domestic hot water temperature adjustment knob back to
the required position.
This function cannot be activated when the boiler is OFF: mode selector (fig.32) on
OFF.
Adjusting the heating water temperature with an external probe
connected
When an external probe is installed, the delivery temperature is automatically selected by the system, which quickly adjusts the ambient
temperature according to variations in the outside temperature.
If you want to alter the temperature value (increasing or reducing
the value automatically calculated by the electronic card), use the
heating water temperature selector: turn it clockwise to increase the
temperature, or anticlockwise to reduce it.
The correction possibility is between - 5 and + 5 comfort levels which
are shown on the digital display by rotating the knob.
Adjustment of the domestic hot water temperature
To adjust domestic water temperature (bathrooms, showers, kitchen, etc.), turn the knob with the
symbol (fig. 33) within the area
marked with + and -.
The boiler is in standby until the burner switches on following a heat
request.
The boiler continues to function until the temperatures set on the
boiler are reached, or the heat request terminates; it will then go back
to standby.
If the red indicator light near the
symbol (fig. 34) on the command
panel lights up, this means the boiler is in temporary stop status (see
the chapter on light signals and faults).
The digital monitor indicates the fault code detected (fig. 34).
Automatic Ambient Adjustment System (S.A.R.A.) (fig. 35)
By setting the heating water temperature selector to the area marked
by AUTO, the S.A.R.A. self-adjusting system is activated (frequency
0.1 sec. on; - 0.1 sec. off; duration 0.5): according to the temperature
set on the ambient thermostat and the time employed to reach it,
the boiler varies automatically the heating water temperature reducing the operating time, allowing great operation comfort and energy
saving.
Reset function
To restore operation, set the function selector to
off (fig. 36), wait
5-6 seconds then bring it 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.
When a remote control BeSMART is connected, the reset of faults
can be done also on the remote control itself, pressing for one second the BACK/RESET (button) (fi g. 37).
N.B. If the attempts to reset the appliance do not activate operation,
contact the Technical Assistance Centre.

gases probe counter >2.500).
Once the cleaning operation has been completed, reset to zero the
total hour meter with special kit supplied as an accessory following
procedure indicated below:
disconnect the electrical supply;
remove the shell and turn the instrument panel;
remove the electrical parts inspection cover, undoing the 2 fixing
screws;
as you electrically power the boiler press the CO button for at least 4
seconds to check that the counter resets. Remove and restore power to the boiler; on the display the counter is shown after the “-C-”
indication.
Live electrical parts (230 Vac).
NOTE
The meter resetting procedure should be carried out after each indepth cleaning of the primary exchanger or if this latter is replaced.
To check the status of the totalled hours multiply the value shown by
100 (ex: shown value of 18 = pre totalled 1.800 – shown value of 1=
totalled hours 100). The boiler continues to operate normally even
with the alarm active.

4.5 Boiler configuration
On the electronic card there is a series of jumpers (JPX) which allow
the boiler to be configured; access is possible by removing the electrical parts inspection cover after setting the main switch to off.
To access the card operate as follows:
- set the system's main switch to off
- undo the shell fixing screws, then move the shell base forward and
then upwards to unhook it from the chassis
- lift and then turn the instrument panel upside down
- remove the electrical parts inspection cover, undoing the 2 fixing
screws to access the jumpers (fig. 39)

the display shows the value of the KT curves multiplied by 10
(example 3.0 = 30)
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
MySMART C.S.I.

on the type of system). It is carefully calculated by the installer on the
basis of the following formula:
KT =
Design delivery temp - Tshift
20 - Design min outside temp
Tshift = 30 °C standard system
25 °C floor system
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 1.0 and curve 1.5. Choose the nearest curve, i.e. 1.5.
Selection of the KT must be made by acting on the P3 trimmer on the
card (see multi-wire electrical diagram).
To access P3:
1. remove the shell,
2. turn the instrument panel upside down
- remove the electrical parts inspection cover, undoing the 2 fixing
screws
Live electrical parts (230 Vac).
The following KT values can be set:
- standard system: 1.0 - 1.5 - 2.0 - 2.5 - 3.0
- floor system: 0.2 - 0.4 - 0.6 - 0.8
and they will be shown on the display for about 3 seconds after the
P3 trimmer is turned,
TYPE OF HEAT REQUEST
If an ambient thermostat is connected to the boiler (JUMPER 6
not on) (fig. 41)
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 temperature is automatically calculated by the boiler, although
the user may interact with the boiler. 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 modification 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).
If an hourly timer is connected to the boiler (JUMPER JP6 not
on) (fig. 42)
With the contact closed, the heat request is made by the delivery
probe, on the basis of the external temperature, to obtain a nominal
ambient temperature on DAY level (20°C). The opening of the contact does not produce a switch-off, but a reduction (parallel translation) of the climatic curve on NIGHT level (16°C).
This will activate the night time function.
The delivery temperature is automatically calculated by the boiler,
although the user may interact with the boiler.
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 modification 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 for DAY level, and 16°C for NIGHT level).
If the boiler is connected to a remote control (like BeSmart), when
the heat request is made by the REC remote control, the thermoregulation is managed by said remote control (refer to the specifi c instruction manual for this product).
4.7 Adjustments
All boiler regulations and calibrations should be carried out directly and only on the instrument panel in the boiler.
To do this, remove the connection of the remote control panel
by separating the front of the fixing base. After this operation the
knobs of the boiler are active.
The boiler has already been adjusted by the manufacturer. However,
if adjustments must be repeated, for example after special maintenance, replacement of the gas valve or conversion from methane gas
to LPG or propane air, observe the following procedures.
The adjustment of the maximum and minimum output, the maximum
heating and slow ignition, must be made strictly in the sequence indicated, and by qualified personnel only:
1. disconnect the boiler power supply
2. turn the heating water temperature selector to its maximum, selector in correspondence to + (fig. 43)
3. lift and then turn the instrument panel upside down
4. remove the electrical parts inspection cover, undoing the 2 fixing
screws
5. insert jumpers JP1 and JP3 (fig. 44)
6. power the boiler.
“ADJ” will appear on the display for about 4 sec
Modify the following parameters:
7. absolute/domestic maximum
8. minimum
9. maximum heating
10. slow ignition
as described below:
11. turn the heating water temperature selector to set the desired
value
12. press the CO button (fig. 45) and move on to calibration of the
next parameter.
Live electrical parts (230 Vac).
The following icons will appear on the display:
1.
during absolute/domestic maximum calibration
2. during minimum calibration
3. during heating maximum calibration
4.
during slow ignition calibration
End the procedure removing jumpers JP1 and JP3 to store the set
values.
the function can be terminated at any time without storing the set
values and maintaining the previously set ones:
removing jumpers JP1 and J
P3 before all 4 parameters have been set
- turning the mode selector to OFF/RESET.
- disconnecting the mains voltage.
- 15 minutes after activation.
The calibration does not entail the ignition of the boiler.
By rotating the heating setpoint selector knob, the number of ro-
tations expressed in hundreds (e.g. 25 = 2.500 rpm) is automatically displayed.
The calibration parameter display function is activated with the selector
on summer or winter and pressing the CO button on the card regardless of whether or not there is a heat request.
The function cannot be activated if a remote control is connected.
When this function is activated, the calibration parameters each appear
(in the order shown below) for 2 seconds. The relative icon is indicated
in line with each parameter, and the fan rotation value (expressed in
hundreds)
1. Maximum
2. Minimum

4.8 Gas conversion (fig. 47)
It is easy to transform gas from one family to gas belonging to another
family even with the boiler installed.
This job must be done by professionally qualifi ed personnel only.
The boiler is supplied to run on natural gas (G20) – see the product
rating plate for details.
The boiler can be transformed to use propane gas using a special kit.
Follow the instructions given here below for disassembly:
- Switch off the power to the boiler and turn off the gas cock.
- Remove the panel and casing.
- Lift up and rotate the instrument panel.
- Open the air box cover.
- Unscrew the screws fastening the silencer (A) and remove it.
- Disconnect the mixer gas ramp. Unscrew the clamp screws and
relative mixer springs to fan and then remove it.
- Loosen the plastic Venturi (B) by levering from under the teeth (BE
CAREFUL NOT TO FORCE THEM) and press from the opposite
side until it is completely extracted from the aluminium shell.
- Replace the plastic Venturi with the one contained in the kit.
- Reassemble the mixer with the fl ap in a horizontal position and
the spacer springs placed at 120° as shown in the fi gure.
- Reassemble gas ramp working vice versa.
- Switch on the power to the boiler and turn on gas cock again.
- Check the number of times the fan turns.
- Fill in and stick on the accompanying transformation data label.
- Close the air box cover.
- Close up the instrument panel again.
- Reassemble the casing and panel.
Programme the “Gas type” parameter and regulate the boiler following the instructions in the “Adjustments” section.
Transformation must be done by qualifi ed personnel only.
After completing transformation, regulate the boiler again
following instructions given in the specifi c paragraph and
apply the new identifi cation label from the kit.
Check that fl ap and Clapet are working correctly (all open
at rated fl ow, all closed at minimum fl ow)
RANGE RATED
This boiler can be adapted to the heating requirements of the system,
in fact it is possible to set the maximum delivery for heating operation
of the boiler itself:
- switch off the power supply
- setting the heating water temperature selector at the maximum value
- remove the shell
- turning the instrument panel towards you
- unscrew the two screws of the small cover on the electronic board to
have access to the terminals
- insert JP1 jumper
- power up the boiler.
The display shows “ADJ” for about 4 sec.: it is then possible to change
the maximum heating value by means of the heating water temperature
selector and the CO button in order to set and confirm the desired
value.
The icon
will appear on the display.
Finish the procedure by removing the jumper JP1 to store the set
values.
Once the desired output (maximum heating) has been set, note the
value on the table on the back cover.
For subsequent controls and adjustments, refer to the set value.
The calibration does not entail the ignition of the boiler. By rota-
ting the heating setpoint selector knob, the value expressed in
hundreds (e.g. 25 = 2500 rpm) is automatically displayed.
The boiler is supplied with the adjustments shown in the table.
Depending on plant engineering requirements or regional flue gas
emission limits it is, however, possible to modify this value, referring
to the graphs.

5 - MAINTENANCE
To ensure product characteristics and efficiency remain intact and
to comply with prescriptions of current regulations, it is necessary to
render the appliance to systematic checks at regular intervals.
When carrying out maintenance work, observe the instructions given
in chapter 1 “Warnings and safety”.
Turn off the appliance before carrying out work or maintenance of
structures near the flue discharge connections and/or fume discharge devices and their accessories. Once work is completed, a
qualified technician must check the efficiency of the appliance.
IMPORTANT: before undertaking any maintenance or cleaning operations, use the switch of the appliance itself and the system to
interrupt the electrical supply and close the gas supply using the
tap on the boiler.
IT IS also OBLIGATORY
to disconnect the cable connecting the
WiFi Box and the boiler
return power to the boiler
interrupt the vent cycle as described in the section “4.2 Appliance
ignition” on page 10.
5.1 Routine maintenance
This normally means the following tasks:
- removing any oxidation from the burner;
- removing any scale from the heat exchangers;
- checking and cleaning the drainage pipes;
- checking the external appearance of the boiler;
- checking the ignition, switch-off and operation of the appliance, in
both domestic water mode and heating mode;
- checking the seal on the gas and water couplings and pipes;
- checking the gas consumption at maximum and minimum output;
- checking the position of the ignition-flame detection glowplug;
- check the “no gas” safety system;
- check operation of the check valve if it is installed (see section 3.12
“Installation on collective flues in positive pressure”).
cleaning the filter inside the heating return line tap. Follow the

- Do not clean the appliance or its parts with easily inflammable
substances (e.g. benzine, alcohol, etc.).
Do not clean panels, painted parts and plastic parts with paint thinner.
Panel cleaning must be carried out only with soapy water.
After routine and extraordinary maintenance operations have
been carried out, fi ll the siphon, following the instructions in the
section “Preliminary cheks”.
5.2 Extraordinary maintenance
These tasks restore appliance operation in accordance with the design and regulations - e.g. following the repair of an accidental fault.
This normally means:
- replacement
- repair
- overhaul of components.
These tasks require special means, equipment and tools.
During the initial
installation phase, or in the event of extraordinary maintenance, you are advised to activate the procedure to
discharge air from the heating circuit and boiler (see section 3.4).
5.3 Checking the combustion parameters
To carry out the combustion analysis, proceed as follows:
- Set the mode selector to to switch off the boiler (fig. 48)
- Turn the domestic hot water temperature selector to the position
(fig. 48)
- Wait for the burner to ignite (about 6 seconds). The display shows
“ACO” and the boiler operates at maximum heating output
- Remove the screw C and the cover E on the air box (see fig. 49)
- insert the analyser probes in the prescribed positions on the air box
The flue gas analysis probe should be inserted until its reaches
the stop.
- Check that the CO2 values correspond to the ones indicated in the
tables shown below”; if the value shown is different proceed with
changes as indicated in the “Gas valve calibration” chapter.

6 - CIRCULATOR SETTINGS
Circulator residual discharge head
The boilers is equipped with an already hydraulically and electrically
connected circulator, whose useful available performance is indicated in the graph.
The circulator comes set from the factory with a 6 metre discharge
head curve.
The boiler is equipped with an anti-blocking system which starts up
an operation cycle after every 24 hours in standby with the mode
selector in any position.
The "antiblocking" function is active only if the boiler is electri-
cally powered.
Operating the circulator without water is strictly forbidden.
If you need to use a different curve you can select the desired level
on the circulator.
ENGLISH
16
Below the main characteristics and the ways to set up their desired
operation are listed.
User interface
The user interface is made up of a button (A), a two-coloured red /
green LED (B) and four yellow LEDs (C) arranged in a row.
The user interface allows the operating performance to be viewed
(operating status and alarm status) and it also allows the circulator
operating modes to be set.
The performance, indicated by the LEDs (B) and (C) is always visible
during normal operation of the circulator whereas the settings can be
carried out by pressing the button (A) .
Operating status indication
When the circulator is in operation the LED (B) is green. The four
yellow LEDs (C) indicate the electrical energy consumption (P1) as
shown in the following table

Display of active settings
With the circulator powered, press briefly on the button (A) to view
the active configuration of the circulator. The LEDs indicate the active
settings.
In this phase no variations can be made to the circulator configuration. Two seconds after the button (A) has been pressed the user
interface returns to the normal operating status display.
Key lock function
The purpose of the key lock function is to prevent accidental modifications to the settings or the improper use of the circulator.
When the key lock function is activated, long-pressing the button (A)
is prevented. This prevents the user from entering the circulator's
operating modes setting section.
Enabling/disabling the key lock function is achieved by pressing the
button (A) for more than 10 seconds. During this step all of the LEDs
(C) will flash for 1 second.
Changing the operating mode
In normal operating conditions the circulator works with the factory
settings or the last settings carried out.
To change the configuration:
Ensure that the key lock function is deactivated.
Press the button (A) for more than 2 seconds until the LEDs begin
to flash. Short-press the button (A) within 10 seconds and the user
interface will move on to display the next settings. The various available settings will appear in a cyclic sequence.
If the button (A) is not pressed, the last setting will be stored.

1 - ADVERTENCIAS Y SEGURIDAD
Las calderas producidas en nuestros establecimientos se fa-
brican prestando atención a cada uno de los componentes de
manera tal de proteger tanto al usuario como al instalador contra eventuales accidentes. Se aconseja al personal cualificado,
después de cada intervención efectuada en el producto, que
preste particular atención a las conexiones eléctricas, sobre
todo por lo que se refiere a la parte no cubierta de los conductores, que de ninguna forma tiene que sobresalir de la bornera,
evitando de esta forma el posible contacto con las partes vivas
de dicho conductor.
El presente manual de instrucciones, junto con el del usuario,
forma parte integrante del producto: hay que comprobar que
forme parte del equipamiento del aparato, incluso en el caso
de cesión a otro propietario o usuario, o bien de traslado a otra

La instalación de la caldera y cualquier otra intervención de
asistencia y de mantenimiento deben ser realizadas por personal cualificado según las indicaciones de las normas en vigor
y en conformidad con las normas UNI 7129-7131, UNI 11071 y
sus actualizaciones.
Efectuar el mantenimiento de la caldera por lo menos una vez
al año, programándolo anteriormente con el Servicio de Asistencia Técnica.
Se aconseja al instalador que instruya al usuario sobre el fun-
cionamiento del aparato y sobre las normas fundamentales de
seguridad.
