1.GENERAL SAFETY DEVICES
The boilers produced in our factory are built with
care down to the last component to protect both
the user and installer from eventual accidents. We
therefore recommend qualified personnel that after
working on the product they should pay particular
attention to the wiring, especially the bare wires,
that must not be exposed outside the terminal board
for any rason to prevent any contact with the live
parts of the wiring.
This instructions manual is integral parts of the
product. Make sure they remain with the boiler, even
if it is transferred to another owner or user or moved
to another heating system. In case of loss or
damage, please contact your local Technical
Assistance Service for a new copy.
This boiler may only be installed and serviced by
qualified fitters who satisfy the requirements of local
rules. Work must be done in compliance with
regulations in force and subsequent updates.
The installer shall instruct the user in the operation
of the boiler and the safety devices.
This boiler may only be used for what it was
expressly built to do. The manufacturer declines all
contractual and non-contractual liability for injury to
persons or animals or damage to property deriving
from errors made during installation, adjustment and
servicing and from improper use.
This appliance is used to produce hot water and
must therefore be connected to a heating and/or a
domestic hot water system, according to its perfor-
mance and power.
After removing the packaging, make sure the
contents are undamaged and complete. If this is
not the case, contact your dealer.
The safety valve outlet must be connected to a
suitable collection and venting system. The
manufacturer declines all liability for any damage
caused by the safety valve.
The safety and automatic adjustment devices on
the appliance must never be modified during its life-
time, except by the maker or dealer.

switch it off and do not attempt to repair it yourself.
Immediately after installation, inform the user that:
- in the event of leaks, he/she must shut off the
water supply and promptly inform the Technical
Assistance Service
- GREEN C.S.I.: he/she must check from time to
time to make sure the symbol is not lit on the
control panel. This symbol means that the
pressure in the water system is incorrect. If
necessary, fill the system as described in the
paragraph “Boiler functions”
- GREEN R.S.I.: must periodically check, on the
display, that the pressure value is between 1 and
1,5 bar; if not fill the system as described in the
paragraph

Exclusive GREEN C.S.I. is a C-type condensation wall-
mounted boiler for heating and producing domestic hot
water.
Exclusive GREEN R.S.I. is a C-type condensation wall-
mounted boiler and is able to operate in different
conditions:
-CASE A: only heating. The boiler doesn’t supply
domestic hot water
-CASE B: only heating with water tank connected,
managed by a thermostat, to prepare domestic hot
water
-CASE C: only heating with water tank connected (kit
available upon request), managed by a temperature
sensor, to prepare domestic hot water. Connecting a
water tank not supplied by us, please be sure that the
NTC sensor ised has the following features: 10 kOhm
at 25°C, B 3435 ±1%.
Depending on the type of installation selected, it is
necessary to set the parameter “domestic hot water
mode”. Refer to pages 24 and 26 for description and
setting parameter operations.
This type of appliance can be installed in any kind of
room as long as the fumes discharge and the comburent
air intake are taken outside the room.
The following types of fumes outlet are available for this
kind of boiler: C13, C13x; C23; C33, C33x; C43, C43x;
C53, C53x; C63, C63x; C83, C83x.
Installation must comply with local standards and
regulations in force.
For proper installation, we remind you that:
• the boiler must not be installed over a kitchen or any
other cooking equipment
• minimum spaces are to be left in order to allow
maintenance operations: at least 2,5 cm every side

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.
3.HYDRAULIC CONNECTIONS
The correct position of the external probe is essential for
the climatic control function to run properly.
The probe must be installed outside the building to be
heated, at about 2/3 of the height of the NORTHERN or
NORTHWESTERN face, far from flue pipes, doors,
windows and sunny areas.
Attaching the external probe to the wall
- To access the terminal board and anchor holes, unscrew
the plastic probe cover from the housing by rotating it
anticlockwise
- Mark the points where the holes will be drilled using
the probe housing as a template
- Remove the box and drill holes for 5x25 expansion
grips
- Fix the housing to the wall using the two supplied
expansion grips
- Unscrew the cable-holding nut, insert the bipolar cable
(with a cross section between 0,5 and 1mm2, not
supplied) for the connection between the probe and
the boiler
- For the electrical connection between the external probe
and the boiler, refer to the chapter “Electric connection”
- Tighten the cable-holding nut properly and close the
cover of the protective box.
The probe must be positioned on a smooth surface.
In the case of a brick wall or a wall with an irregular
surface, provision must be made for a smooth
contact surface.
The maximum length of the connection between
the external probe and the boiler is 30 m.
The connection cable between the probe and the
boiler must not have connections. If these prove to
be necessary, they must be made watertight and
suitably protected.
Any ducts for the connection cable must be sepa-
rate from other power lines (230 V.a.C.).
4.INSTALLINGTHE EXTERNAL PROBE
The outlet collector collects: the condensate water, any
evacuation water from the safety valve and the system
outlet water.
The collector must be connected, by means of a rubber
pipe (not supplied), to a suitable collection and evacuation
system in the storm water outlet and in compliance with
current regulations.

To access the electrical connections, proceed as follows:
- pull the cover towards you and remove (A) (fig. 6a)
- loosen the two fixing screws (C) and remove the shell
(fig. 6b)
- lift up the panel and turn it forwards
- open the terminal board covers making them slide in the
direction of the arrows (fig. 6c).
Connect the appliance to the mains power supply with a
switch featuring a distance of at least 3 mm between each
wire.
The appliance uses alternating current at 230 Volt/50 Hz,
has a power input of 130 W (16kW R.S.I. - 25kW C.S.I.)
and 175 W (35kW R.S.I. - 35kW C.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.
Gas and/or water pipes may not be used to earth
electrical equipment.
The manufacturer declines liability for any
damage if the appliance was not connected to an
earth circuit.
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 95.
When replacing the power cable, use a HAR H05V2V2-
F cable, 3 x 0,75 mm2, Ø max. external 7 mm.
7.ELECTRIC CONNECTION
Fig. 6c
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.

The external diameter of the collector is 20 mm: we
therefore suggest using an Ø18-19 mm pipe, to be closed
with a suitable clamp (not supplied).
The manufacturer is not responsible for any damage
caused by the lack of a collection system.
The outlet connection line must have a guaranteed seal.
The manufacturer of the boiler is not responsible for any
flooding caused by interventions of the safety valve.

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. 7a and 7b) to open it;
• making sure the cold water inlet tap is open (B, fig. 7a)
(GREEN C.S.I. only)
• opening the filling tap (C, on the boiler for GREEN C.S.I.,
external for GREEN R.S.I.) until the pressure on the
hydrometer (D) is between 1 and 1,5 bar (blue zone)
(fig. 7a and 7b).
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: air extraction from the boiler takes place
automatically, through two automatic bleeding valves, A
and E.
The first is situated on the pump, while the second is
inside the air chamber.
NOTE (GREEN C.S.I. only): the boiler is also equipped
with a semi-automatic filling mechanism.
The first system-filling operation must be carried out by
opening tap C with the boiler turned off.
NOTE (GREEN R.S.I. only): manual filling tap is not
supplied with the boiler, foresee one external or verify if
external water tank has one.
Before starting to empty it, remove the electrical feeder
by positioning the general switch for the system on “off”.
• Close the interception devices for the thermal system
• Loosen the system outlet valve (F) manually
• The water from the system is discharged through the
outlet collector (G).
DHW system emptying (GREEN C.S.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.
8.FILLING AND EMPTYING THE SYSTEM
ATTENTION
The collector must be connected, by means of a rubber
pipe (not supplied), to a suitable collection and evacuation
system in the storm water outlet and in compliance with
current regulations. The external diameter of the collector
is 20 mm: we therefore suggest using an Ø18-19 mm pipe,
to be closed with a suitable clamp (not supplied).
The manufacturer is not responsible for any damage
caused by the lack of a collection system.

AND BURNING AIR SUCTION
“FORCED OPEN” INSTALLATION
(TYPE B23, intake inside and outlet outside)
Fumes outlet duct ø 80 mm
The fumes outlet duct can be aimed in the most suitable
direction for installation needs.
To install follow the instructions supplied with the kit.
In this configuration, the boiler is connected to the
ø 80 mm fumes outlet duct by means of a ø 60-80
mm adaptor.
In this case, the combustion supporting air is taken
from the room in which the boiler is installed, which
must be a suitable and ventilated technical room.
Non-insulated fumes outlet ducts are potential
sources of danger.

INSTALLATION “SEALED” (TYPE C)
Boiler is a C-type appliance (sealed chamber) and must
be safely connected to fume exhaustion duct and burn-
ing 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 col-
lector is required.
The fumes outlet duct must slope by 1% towards the
condensate collector.
Uninsulated fumes outlets are potential hazards.
The boiler automatically adapts ventilation accord-
ing to the type of installation and the length of the
duct.
Do not obstruct or narrow the comburent air inlet
duct in any way.
To install follow the instructions supplied with the kit.

The combustion-supporting air intake duct must be
connected to the entrance after having removed the
closing cap, attached with three screws, and having
attached a suitable adaptor.
The fumes outlet duct must be connected to the fumes
outlet after having installed a suitable adaptor.
For the installation process, follow the instructions
supplied with the kit for the specific accessory for
condensation boilers.
The fumes outlet duct must slope by 1% towards the
condensate collector.
The boiler automatically adapts ventilation accord-
ing to the type of installation and the length of the
duct. Do not obstruct or narrow the comburent air
inlet duct in any way.

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 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. 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.
GREEN C.S.I.:
- AUTUMN : 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 “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 : 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
“Functions”).
- SPRING : with the selector in this position, just the
traditional domestic hot water function is activated.
- SUMMER : 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 SPRING and WINTER) may be instable.
GREEN R.S.I.:
- AUTUMN : with the selector in this position the
S.A.R.A. function is enabled (see chapter “Functions”).
- WINTER : with the selector in this position the
S.A.R.A. Booster function is enabled (see chapter
“Functions”).
Note: both in autumn and in winter, if external water
tank is connected, the boilre provides hot water (with
a temperature stabiliser) to the water tank, to let
preparing the domestic hot water (see parameters table).
- SPRING (only with water tank connected): with
the selector in this position the boiler provides water
(with a temperature stabiliser) to the water tank, to let
preparing the domestic hot water (see parameters
table).

- SUMMER (only with water tank connected): with
the selector in this position, the boiler provides just
water (with a temperature stabiliser but smaller than
spring position) to the water tank, to let preparing the
domestic hot water (see parameters table).
Adjusting heating water temperature
Turning the selector A(fig. 18), after having positioned
the selector mode on autumn or winter , 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 21.
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).
GREEN C.S.I.:
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.
GREEN R.S.I.:
Adjusting domestic hot water temperature
CASE A only heating - adjusting not applicable
CASE B only heating + water tank with thermostat: in
this condition every time there is a request
from the water tank thermostat, the boiler
supplies hot water to preparing domestic hot
water.
During this operation on the display the icon
flashed.
CASE C only heating + water tank with sensor: to adjust
domestic hot water temperature storaged in
the water tank, turn switch D(fig. 22): clocwise
to increase and anticlockwise to decrease.

Working the boiler
Adjust the ambient thermostat to the required tempe-
rature (approx. 20 °C).
If there is a demand for heating water, the boiler starts
and the symbol is shown on the display (fig. 23). 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. 24).
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. 25). When the boiler remains powered with the
gas tap open, it is protected by the following systems:
- anti-freeze (fig. 26): when the temperature of the water

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. 25).
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. 27).
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.

Boiler functions
GREEN C.S.I.:
Semi-automatic filling
The boiler features a semi-automatic filling device
which turns on by pressing the button when the
corresponding symbol is shown on the display (fig.
28).
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. 29).
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. 30b); if it falls below a minimum
safety value (0.3 bar), fault code 41 appears on the
display (fig. 30a) 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).
GREEN R.S.I.:
Filling the circuit
If circuit pressure reaches 0.6 bar, the pressure value
flashes on the display (fig. 30b); if it falls below a minimum
safety value (0.3 bar), fault code 41 appears on the
display (fig. 30a) 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 fill the
circuit until the pressure value on the transducer ranges
between 1 and 1,5 bars.
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. 31).

S.A.R.A. function
If the “autumn” mode is selected, the S.A.R.A.
(Automatic Ambient Adjustment System) function can
be activated.
Turn the heating water temperature selector to a tempe-
rature ranging between 55 and 65 °C.
The S.A.R.A. self-adjustment system activates: depending
on the temperature set on the ambient thermostat and the
time taken to reach it, the boiler automatically adjusts the
heating water temperature to reduce operating times,
thereby increasing operating comfort and energy saving.
