AND BURNING AIR SUCTION
Refer to regulations in force for exhaustion of combus-
tion products.
Boiler is provided for without fume exhaustion/air suc-
tion kit, since forced draught sealed chamber accesso-
ries can be used, as they better adapt to installation
characteristics.
"FORCED OPEN" INSTALLATION
(TYPE B23, 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 burn-
ing 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.
Consult the graphs to find out whether a condensate col-
lector is required.
The fumes outlet duct must slope by 1% towards the
condensate collector.
Uninsulated fumes outlets are potential hazards.
The boiler automatically adapts ventilation accord-
ing 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.
FUMES EXHAUSTION
For fume extraction and burning air restoration in boiler,
use original pipes or other EC-certified pipes with equiva-
lent 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.
