EXCLUSIVE GREEN C.S.I. - R.S.I.
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 tempera-
ture and the length of the duct.
Rectilinear length means without bends, outlet ends and connections.
The fumes outlet duct must slope by 1% towards the condensate collector.
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.

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 collector.
The boiler automatically adapts ventilation according to the type of instal-
lation 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.

Suggestions to correctly eliminate air from the heating system and
boiler (Fig. 8.2)
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;
5. Turn on a tap to activate request for hot water (for instantaneous boilers
only; use the water heater thermostat for boilers just for heating connected
to an external water heater) for an interval of 30” every minute to make the
three-way cycle from heating to hot water and vice versa about ten times
(the boiler will be go into alarm as there is no gas under these circumstances,
it must therefore be reset every time this happens);
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
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 sealed chamber 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 installation
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.
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.
