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.
Provision must be made for a 1% slope of the fumes
outlet duct towards the boiler.

For fume extraction and burning air restoration in boiler,
use original pipes or other EC-certified pipes with equiva-
lent 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.

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 split duct can be aimed in the most suitable direction
for installation needs.
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.
For an indication of the maximum lengths of every
single pipe, refer to the graphs.
Using longer ducts causes a loss in the power of
the boiler.
