1.10 OUTDOOR INSTALLATION IN A
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..).
is type of installation is only possible when
permitted by the laws in force in the appliance’s
country of destination.
• Conguration type B, open chamber and
forced draught.
Using the special coverage kit one can achieve
direct air intake (Fig. 1-10) and fumes exhaust in
a single ue or directly outside. In this congura-
tion it is possible to install the boiler in a partially
protected place. In this conguration the boiler
is classied as type B.
With this conguration:
- air intake takes place directly from the envi-
ronment in which the appliance is installed
(outside);
- the fumes exhaust must be connected to its own
single ue (B
23
) or ducted directly outside via a
vertical terminal for direct exhaust (B
53
) or via
an Immergas ducting system (B
53
).
The technical regulations in force must be
respected.
Flue gas separator adjustment. For correct
functioning of the boiler in conguration with
direct air intake it is necessary to regulate the ue
gas shutter according to that stated in the relative
tables (page 10).
• Coverage kit assembly (Fig. 1-11). Remove
the two plugs and the gaskets present from
the two lateral holes with respect to the central
one. Now cover the right intake hole using the
relevant plate, xing it onto the le side using
the 2 previously-removed screws. Install the
Ø 80 outlet ange on the central hole of the
boiler, taking care to insert the gasket supplied
with the kit and tighten by means of the screws
provided. Install the upper cover, xing it using
the 4 screws present in the kit, positioning the
relevant gaskets. Engage the 90° Ø 80 bend with
the male end (smooth) in the female end (with
lip seal) of the Ø 80 ange unit until it stops.
Introduce the gasket, making it run along the
bend. Fix it using the metal sheet plate and
tighten by means of the clips present in the kit,
making sure to block the 4 gasket aps. Fit the
male end (smooth) of the exhaust terminal into
the the female end of the bend 90° Ø 80, mak-
ing sure that the relevant wall sealing plate is
already tted; this will ensure hold and joining
of the elements making up the kit.
Max. length of exhaust duct. e ue pipe
(vertical or horizontal) can be extended to a
max. length of 12 linear metres, using insulated
pipes (Fig. 1-27). To prevent problems of ue
gas condensate in the exhaust pipe Ø 80, due to
ue gas cooling through the wall,the length of the
pipe (not insulated) must be limited to just 5 m.
• Conguration without cover kit in a partially
protected location (type C boiler).
By leaving the side plugs tted, it is possible
to install the appliance externally, in partially
covered places, without the cover kit. Installation
takes place using the Ø 60/100 and Ø 80/125
concentric horizontal intake/ exhaust kits. Refer
to the paragraph relative to indoor installation. In
this conguration the upper cover kit guarantees
additional protection for the boiler. It is recom-
mended but not compulsory.
