1.12 OUTDOOR INSTALLATION IN A
PARTIALLY PROTECTED AREA.
N.B.:
a partially protected area is one in which the
appliance is not exposed to the direct action of the
weather (rain, snow, hail, etc..).
.
•
Configuration type B, open chamber and
forced draught.
Using the special coverage kit one can achieve
direct air intake (Fig. 1-9) and fumes exhaust in
a single flue or directly outside. In this configura-
tion it is possible to install the boiler in a partially
protected place. In this configuration the boiler
is classified as type B
23
.
With this configuration:
- 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 flue (B23) or ducted directly outside via
a vertical terminal for direct exhaust (B53) or
via an Immergas ducting system (B53).
The technical regulations in force must be
respected.
•
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, fixing it onto the left side using
the 2 previously-removed screws. Install the
Ø
80 outlet flange 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, fixing 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 flange unit until it
stops. Introduce the gasket, making it run along
the bend. Fix it using the sheet steel plate and
tighten by means of the straps present in the
kit, making sure to block the 4 gasket flaps. Fit
the male end (smooth) of the exhaust terminal
into the the female end of the bend 90°
Ø
80,
making sure that the relevant wall sealing
plate is already fitted; this will ensure hold and
joining of the elements making up the kit.
Max. length of exhaust duct.
The flue pipe (both
vertical or horizontal) can be
extended to a max.
length of 3
0
linear metres
.
•
Coupling of extension pipes. To install push-fit-
ting extensions with other elements of the flue,
proceed as follows: Couple the pipe or elbow
with the male side (smooth) in the female side
(with lip seal) to the end stop on the previously
installed element. This will ensure sealing
efficiency of the coupling.
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 left between a terminal or a balcony
above. With installations under a balcony, the
X
+
Y
+
Z
+
W height evaluated with regard to the
balcony above must be equal to, or more than,
2000 mm (Fig. 1-10). The term W must only be
considered if the balcony above has closed bal-
ustrade (W=0 if the balustrade is open).
•
Configuration without cover kit in a partially
protected location (type C boiler)
By leaving the side plugs fitted it is possible
to install the appliance externally without the
cover kit. Installation takes place using the
Ø
60/100,
Ø
80/125 and separator
Ø
80/80
concentric intake/ exhaust kits. Refer to the
paragraph relative to indoor installation. In
this configuration the upper cover kit guaran-
tees additional protection for the boiler. It is
recommended but not compulsory.
The cover kit includes:
N° 1 Thermoformed cover
N°1 Gasket clamping plate
N°1 Gasket
N°1 Gasket tightening strap
N°1 Intake hole covering plate
The terminal kit includes:
N° 1 Gasket
N° 1 Discharge flange Ø

N° 1 Bend
