Fumes Exhaustion And Burninig Air Suction - Beretta EXCLUSIVE GREEN HE C.S.I. Installer And User Manual

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. Using a CH11 spanner open the manual air vent valve located above
the air box; the tube supplied with the boiler must be connected to the
valve to let out the water into an outside container.
2. Open the manual system filling stopcock on the water group, 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;
Activate request for hot water as follows:
5.
instant 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 - 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)
C23 - Concentric exhaustion in common chimney (suction and exhaustion
in the same chimney)
C33 - Concentric roof exhaustion. Outlets like C13
C43 - Exhaustion and suction in common separate chimneys, but subject
to similar wind conditions
C53 - Wall or roof separate exhaustion and suction in different pressure areas.
Exhaustion and suction must never be located on opposite walls
C63 - Exhaustion and suction with separately certified and sold pipes (1856/1)
C83 - Single or common chimney exhaustion and wall suction
C93 – Exhaust on roof (similar to C33) and air
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.
"FORCED OPEN" INSTALLATION (TYPE B23P-B53P, intake inside
and outlet outside) - Fumes outlet duct Ø 80 mm (Fig. 1.13)
The fumes outlet duct can be aimed in the most suitable direction for instal-
lation 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.

INSTALLATION "SEALED" (TYPE C)
Boiler is a C-type appliance (sealed chamber) and must be safely connected
to fume exhaustion duct and burning air suction duct, both getting outside;
appliance cannot operate without these ducts.
Concentric outlets (Ø 60-100) (Fig. 1.14)
Concentric ducts may be placed in the most suitable direction for installation
requirements but special care must be taken as regards the external tempe-
rature and the length of the duct.

The fumes outlet duct must slope by 1% towards the condensate col-
lector.
Uninsulated fumes outlets are potential hazards.
The boiler automatically adapts ventilation according 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.
Concentric outlets (Ø 80-125) (Fig. 1.14)
For this installation it is necessary to install the suitable adaptor kit. Ducts
may be placed in the most suitable direction for installation requirements.
For the installation process, follow the instructions supplied with the kit for
the specific accessory for condensation boilers.

Twin outlets (Ø 80) (Fig. 1.15)
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 col-
lector.
The boiler automatically adapts ventilation according 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 (Fig. 1.16).
Using longer ducts causes a loss in the power of the boiler.
