Gas Connection; Electric Connection - Beretta Exclusive Green E C.S.I. Serie Manual Del Instalador

EXCLUSIVE GREEN E C.S.I. - R.S.I.
Loosen the cable grommet screw, push in the probe connection cable
and connect it to the electrical terminal.
b
Remember to firmly secure the cable grommet to prevent humidity
from entering.
Put the card back into its housing.
Close the upper plastic cover by turning it clockwise. Firmly secure the
cable grommet.
5 - CONDENSATE COLLECTION
The outlet collector A (Fig. 1.7) collects: the condensate water, any
evacuation water from the safety valve and the system outlet water.
b
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 Ø 18-19 mm pipe, to be closed with a suitable clamp (not
supplied).
b
The manufacturer is not responsible for any damage caused by
the lack of a collection system.
b
The outlet connection line must have a guaranteed seal.
b
The manufacturer of the boiler is not responsible for any flooding
caused by interventions of the safety valve.

6 - GAS CONNECTION

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.

7 - ELECTRIC CONNECTION

To access the electrical connections, proceed as follows:
- unscrew the lower cover fixing screw C, (Fig. 1.4)
- pull the cover towards you and remove (A-B) (Fig. 1.5)
- loosen the fixing screws (D) and remove the shell (Fig. 1.2)
- lift up the panel and turn it forwards
- open the terminal board covers making them slide in the direction of
the arrows (Fig. 1.8: E high voltage connections 230 V, F low voltage
connections, G water tank sensor connections only R.S.I. model).
Connect the appliance to the mains power 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 Volt/50 Hz 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.
b
The earth conductor must be a couple of cm longer than the others.
b
Gas and/or water pipes may not be used to earth electrical
equipment.
b
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 usage or failing
to earth the boiler.
Use the supplied power cable to connect the boiler to the mains power
supply. Connect the room thermostat and/or time clock as shown in the
electrical diagrams. When replacing the power cable, use a HAR
H05V2V2-F cable, 3 x 0,75 mm
8 - FILLING AND EMPTYING THE SYSTEM
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:
- turn the caps of the lower (A) and upper (E) automatic bleed valves
two or three times; leave A and E valve caps open for continual air
venting (Fig. 1.9);
- making sure the cold water inlet tap is open
- opening the filling tap (B, on the boiler for C.S.I., external for R.S.I.)
until the pressure on the hydrometer (C) is between 1 and 1,5 bar
(blue zone) (Fig. 1.9).

, Ø max. external 7 mm.

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 (C.S.I. model only): the boiler is also equipped with a semi-
automatic filling system. The first system-filling operation must be carried
out by opening tap B with the boiler turned off.
NOTE (R.S.I. model 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 (D) manually
- The water from the system is discharged through the outlet collector (F).
DHW system emptying (C.S.I. model 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.
Suggestions to correctly eliminate air from the heating system and
boiler (Fig. 1.10)
We recommend carrying out the sequence of operations given below
during first installation or with extraordinary maintenance work:
1. Open the automatic air vent by turning the plug on the lower valve
two or three turns, to bleed the air continuously, leave valve plug A
open.
2. Open the filling tap (on the boiler for GREEN E C.S.I., external for
GREEN E R.S.I.) and wait until the water starts coming out of the
valve;
3. Switch on the boiler leaving the gas cock closed;
4. Use the room thermostat or the remote control panel to activate
request for heat so that the three-way will turn to heating;
5. Activate request for hot water as follows:
instantaneous boilers: turn on a tap for 30" every minute so that the
three-way cycles from heating to domestic hot water and vice versa
about ten times (here the boiler will go into alarm as it lacks gas and
has to be reset every time this happens).
heating-only boilers connected to an external water tank: use
the water tank thermostat;
6. Continue the sequence until water only comes out of the manual air
vent valve and the flow of air has finished; close the manual air vent
valve at this point;
7. Make sure the system is at the correct pressure (1 bar is ideal);
8. Close the manual system filling stopcock on the water group;
9. Open the gas cock and ignite the boiler.
9 - FUMES EXHAUSTION AND BURNING AIR SUCTION
EXHAUSTION CONFIGURATIONS (Fig. 1.11-1.12)
Boiler is homologated for the following exhaustion configurations:
B23P-B53P Suction in room and discharge outside
C13-C13x Concentric wall exhaustion. Pipes can separately start from
boiler, but outlets must be concentric or close enough to be
subject to similar wind conditions (within 50 cm)
C33-C33x Concentric roof exhaustion. Outlets like C13
C43-C43x Exhaustion and suction in common separate chimneys, but
subject to similar wind conditions
C53-C53x Wall or roof separate exhaustion and suction in different
pressure areas. Exhaustion and suction must never be
located on opposite walls
C63-C63x Exhaustion and suction with separately certified and sold
pipes (1856/1)
C83-C83x Single or common chimney exhaustion and wall suction
C93-C93x Exhaust on roof (similar to C33) and air suction from a single
existing smoke pipe.
Refer to regulations in force for exhaustion of combustion products.
Boiler is provided for without fume exhaustion/air suction kit, since forced
draught sealed chamber accessories can be used, as they better adapt
to installation characteristics.
For fume extraction and burning air restoration in boiler, use original
pipes or other EC-certified pipes with equivalent 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 condensing type.
