1.9 OUTDOOR INSTALLATION IN
PARTIALLY PROTECTED AREA.
N.B.: a partially protected location is one in which
the appliance is not exposed to the direct action of
the weather (rain, snow, hail, etc..).
• Conguration type B, open chamber and
forced draught.
The relevant terminal must be used for this
conguration (present in the intake kit for the
installation in question), which must be placed
on the central hole of the boiler (Fig. 1-12). Air
intake takes place directly from the room where
the boiler is installed and ue exhaust in an in-
dividual ue or directly to the outside.
Boiler with this type of conguration are classi-
ed as type B
22
.
With this conguration:
- air intake takes place directly from the envi-
ronment in which the appliance is installed
(external);
- the ue exhaust must be connected to its own
individual ue or channelled directly into the
external atmosphere.
Accordingly, technical standards in force must
be observed.
Max. length of exhaust duct. The flue pipe
(vertical or horizontal) can be extended to a max.
length of 12 linear metres, using insulated pipes
(Fig. 1-28) and limit the length of the Ø 80 normal
ue pipe (not insulated) to just 5 metres.
Example of installation with direct vertical
terminal in partially protected location. When
the vertical terminal for direct discharge of com-
bustion fumes is used, a minimum gap of 300 mm
must be le between the terminal and the balcony
above. e height X+Y+Z+W evaluated with
respect to the balcony above, must be equal to
or more than 2000 mm. (Fig. 1-11). e term W
must only be considered if the balcony above has
closed balustrade (W=0 if the balustrade is open).
• Conguration without cover kit
(boiler type C).
By leaving the side plugs tted, it is possible to
install the appliance externally, in partially co-
vered places, without the cover kit. Installation
takes place using the Ø60/100 and Ø80/125
concentric horizontal intake/ exhaust kits. Refer
to the paragraph relative to indoor installation. In
this conguration the upper cover kit guarantees
additional protection for the boiler. It is recom-
mended but not compulsory.
• Fitting the cover kit. To assemble and con-
gure the cover kit correctly, please refer to the
relative instructions sheet.
