- Close the interception devices for the thermal system
- Open the automatic air vent valve (C)
- Unscrew the drain valve (B) by hand, keeping the elbow on the
hose in position to prevent it coming out of its seating
- The water from the system is discharged through the outlet col-
lector (A)
- Emptying out the lowest parts of the system.
DHW system emptying (fi g. 7)
The hot water system must be emptied every time there is risk of
freezing by:
- turning off the stopcock at the mains
- unscrew the cap on the hose adapter (G)
- connect a plastic hose to the hose adapter of the storage boiler
drain valve (G)
- open the valve drain device
- turning on all the hot and cold taps
- emptying out the lowest parts of the system.
ATTENTION
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 suitable clamp (not supplied). The
manufacturer is not responsible for any damage caused by the lack
of a collection system.
Suggestions to correctly eliminate air from the heating system
and boiler (Fig. 8)
We recommend carrying out the sequence of operations given be-
low during fi rst 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 con-
nected to the valve to let out the water into an outside container.
2. Open the manual system fi lling 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. Activate request for hot water as follows:
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 fl ow of air has fi nished; 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 fi lling stopcock on the water group;
9. Open the gas cock and ignite the boiler.
10- FUMES EXHAUSTION AND BURNING AIR
SUCTION
EXHAUSTION CONFIGURATIONS (fi g. 9)
Boiler is homologated for the following exhaustion confi gurations:
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).
C23-C23x Concentric exhaustion in common chimney (suction and
exhaustion in the same chimney).
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 certifi ed and
sold pipes (1856/1).
C83-C83x Single or common chimney exhaustion and wall suction.
C93-C93x Discharge 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-cer-
tifi ed pipes with equivalent characteristics; check connection is cor-
rect 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 - fi g. 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 confi guration, 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. 11
Concentric ducts may be placed in the most suitable direction for
installation requirements but special care must be taken as regards
the external temperature and the length of the duct.

Rectilinear length means without bends, outlet ends and con-
nections.
The fumes outlet duct must slope by 1% towards the conden-
sate 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.
Concentric outlets (ø 80-125 mm)
For this installation it is necessary to install the suitable adaptor kit.
Ducts may be placed in the most suitable direction for installation re-
quirements. For the installation process, follow the instructions sup-
plied with the kit for the specifi c accessory for condensation boilers.
