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 qualifi ed
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 qualifi ed fi t-
ters who satisfy the requirements of local rules. Work must be
done in compliance with regulations in force and subsequent
updates.
The boiler must be serviced at least once a year. This should
be booked in advance with the Technical Assistance Service.
The installer shall instruct the user in the operation of the boil-
er and the safety devices.
This boiler may only be used for what it was expressly built to

This appliance is used to produce hot water and must there-
fore be connected to a heating and/or a domestic hot water
system, according to its performance and power
After removing the packaging, make sure the contents are
undamaged and complete. If this is not the case, contact your
dealer.
We recommend always being careful to control the degree
of wear of the keep-alive anode during ordinary maintenance
jobs.
The safety valve outlet must be connected to a suitable col-
lection and venting system. The manufacturer declines all li-
ability for any damage caused by the safety valve.
The safety and automatic adjustment devices on the appli-
ance must never be modifi ed during its lifetime, except by the
maker or dealer.
If the appliance develops a fault and/or works badly, 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
- 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 neces-
sary, fi 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 per-
form the following operations:
- turn off the main boiler and general system switches
- close the gas and water taps on both the heating and do-
mestic hot water circuits
- drain the heating and domestic hot water circuits to prevent
freezing.
Connect the outlet collector to a suitable outlet system (refer
to chapter 6).
Safety measures:

2- BOILER INSTALLATION

Boiler must only be installed by qualifi ed personnel in compliance
with current legislation. Boiler is available in the following models:
Model Type
B.S.I. Combined
Exclusive Boiler Green HE B.S.I. is a C-type condensation wall-
mounted boiler for heating and producing domestic hot water,
supplied with a 60 litres inox water tank. Class C appliances 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 fol-
lowing types of fumes outlet are available for this kind of boiler:
B23P; B53P; C13,C13x; C23; C33,C33x; C43,C43x; C53,C53x;
C63,C63x; C83,C83x; C93,C93x. Installation must comply with lo-
cal standards and regulations in force.
For proper installation, we remind you that:
- the boiler must not be installed over a kitchen or any other cook-
ing equipment
- it is forbidden to leave infl ammable substances in the room
- suitably insulate heat-sensitive walls (e.g.: in wood)
- minimum spaces are to be left in order to allow maintenance
operations: at least 2,5 cm every side and 20 cm under the boiler.
Keep the distance of 370 mm from the bottom of the boiler
to the furniture casing: there must be suffi cient space for
dismantling operations if the magnesium anode has to be
cleaned.
Support plate and integrated pre-installation template are provided
for with the boiler (fi g. 2).
Mounting instructions:
- fi x 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 fi xing the boiler support plate (F)
and 2 holes (ø 4 mm) for fi xing the preinstallation 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
- fi x the plate to the wall by the supplied anchor screws
- make hydraulic connections.

3- HYDRAULIC CONNECTIONS

Position and dimensions of hydraulic connections are specifi ed in
fi gure 2:
A - CH return 3/4"
B - CH delivery 3/4"
C - Gas connection 3/4"
D - DHW outlet 1/2"
E - DHW inlet 1/2"
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 exces-
sively hard water.
