EXCLUSIVE BOILER GREEN HE B.S.I.
HYDRAULIC CONNECTIONS
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.
After installing a new system or replacing a boiler, clean the heat-
ing system.
To ensure the product works correctly, after cleaning, additivating
ers, etc.), make sure the characteristics of the water satisfy the
parameters indicated in the table.

grip. Insert the expansion grip into the hole. Remove the card from
its housing. Fix the housing to the wall using the supplied screw.
Attach the bracket and tighten the screw. Loosen the cable grom-
met screw, push in the probe connection cable and connect it to the
to prevent humidity from entering. Put the card back into its hous-
ing. Close the upper plastic cover by turning it clockwise. Firmly
secure the cable grommet.
The sensor must be installed on an external wall of the building
you want to heat, while taking care to comply with the instructions
below:
direct sunlight.
- It must not be near any doors, windows, outlets for air ducts, or
near chimneys or other heat sources.
The electrical connection to the external sensor must be formed
using a two-pole cable (not supplied), with a cross-section of 0,5
to 1 mm
and a maximum length of 30 metres. It is not necessary

to worry about the polarity of the cable for the connection to the
external sensor. Do not form joints in this cable. If a joint has to be
made it must be watertight and adequately protected.
Any conduiting used for the connection cable must be sepa-
rate from the conduits used for the power cables (230 Vac).
CONDENSATE COLLECTION

evacuation water from the safety valve and the system outlet water.
The collector must be connected, by means of a rubber pipe,
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 suit-
able 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
lowing:
- regulations in force are met
- gas type used is the same as set for appliance operation
- pipes are clean.
After installation make sure that all the joints have been made
airtight conforming to standard installation practices.
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

ELECTRIC CONNECTION
To access the electrical connections, proceed as follows:
- lift up the panel and turn it forwards
- open the terminal board covers making them slide in the direc-
voltage connections).
Connect the appliance to the mains electricity supply with a switch
featuring a distance of at least 3,5 mm (EN 60335-1, category III)
between each wire. The appliance uses alternating current at 230
and complies with EN 60335-1. The appliance must be connected
laws.
Live and neutral (L-N) connections should also be respected.
The boiler can operate with phase-neutral or phase-phase power
tor, 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 installer is responsible for making sure that the appliance
has an adequate earthing system; the manufacturer shall not
be held liable for eventual damages caused by incorrect us-
age or failing to earth the boiler.
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.
