the pressure in the water system is incorrect. If necessary, ll the 
system as described in the paragraph “Boiler functions”
- GREEN E R.S.I.: must periodically check, on the display, that the 
pressure value is between 1 and 1,5 bar; if not ll the system as 
described in the paragraph “Boiler functions”
- if the boiler is not planned to be used for a long period, he/she 
should call in the Technical Assistance Service to perform the 
following operations:
- turn off the main boiler and general system switches
- close the gas and water taps on both the heating (C.S.I. - R.S.I.) 
and domestic hot water circuits (C.S.I. only)
- drain the heating (C.S.I. - R.S.I.) and domestic hot water (C.S.I. 
only) circuits to prevent freezing.
b Connect the outlet collector to a suitable outlet system (refer to 
chapter 5).
EN ENGLISH When the product reaches the end of its life it should not be 
disposed of as solid urban waste but should be brought to a

2 - BOILER INSTALLATION
Boiler must only be installed by qualied personnel.
Boiler is available in the following models:
Model Type Category Power
C.S.I. combined C 25 - 30 - 35 kW
R.S.I. CH only C 25 - 35 kW
Exclusive GREEN E C.S.I. is a C-type condensation wall-mounted 
boiler for heating and producing domestic hot water.
Exclusive GREEN E 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 specic chapter for 
description and setting parameter operations.
Exclusive Green E boilers are tted with:
- circulation at adjustable speed (PWM = Pulse-Width Modulation)
- 1:10 modulation, the boiler is designed to automatically modulate the 
ow rate supplied between a maximum and a minimum (see technical 
data)
- Range Rated, indicates that the boiler as a device for adapting to the 
system’s heat requirements, making it possible to adjust the boiler’s 
ow rate to the energy requirements of the building.
The following types of fumes outlet are available for this kind of boiler: 
B23P; B53P; C13,C13x; C33,C33x; C43,C43x; C53,C53x; C63,C63x; 
C83,C83x,C93,C93x.
In B23P/B53P conguration (if installed inside), do not install the appa-
ratus in rooms used as bedrooms, bathrooms, showers or where there 
are open vent stacks without own air exchange. The boiler must be 
installed in an adequately ventilated room. See the UNI 7129-7131 and 
standards for detailed instructions on installing vent stacks, gas pipes 
and to ventilate the room.
In C conguration the boiler can be installed in any type of room and 
there are no limits to aeration conditions and size of room.
The following symbols are used in this manual:
b CAUTION = operations requiring special care and adequate 
preparation
a NOT ALLOWED = operations that MUST NOT be performed
R.S.I.: DHW functions refer only if a water tank is connected (accessory 
available on request).
