DHW system emptying (fig. 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.
9 - FUMES EXHAUSTION AND BURNING AIR SUCTION
EXHAUSTION CONFIGURATIONS (fig. 8)
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
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.

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)
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.

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
requirements. For the installation process, follow the instructions
supplied with the kit for the specific accessory for condensation
boilers.

Twin outlets (ø 80)
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.

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.
Using longer ducts causes a loss in the power of the boiler.
