1.13 OUTDOOR INSTALLATION IN
PARTIALLY PROTECTED AREA
A partially protected area is one in which the appliance
is not exposed to the direct action of the weather (rain,
snow, hail, etc.).
If the appliance is installed in a place where the ambient
temperature drops below -5°C, use the optional antifre-
eze kit, checking the ambient operating temperature
range shown in the technical data table in this in-
struction booklet.
Configuration type B, open chamber and fan assisted (B22 or
B52).
Using the special coverage kit one can achieve direct air intake
and flue gas exhaust in a single chimney or directly outside. In this
configuration it is possible to install the boiler in a partially pro-
tected place. In this configuration the boiler is classified as type B.
With this configuration:
- air intake takes place directly from the environment in which
the appliance is installed (external);
- the flue exhaust must be connected to its own single chimney
(B22) or ducted directly outside via a vertical terminal for direct
exhaust (B52) or via an Immergas ducting system (B52).
The technical regulations in force must be respected.
Cover kit assembly (Fig. 15).
- Remove the two plugs and the gaskets present from the two late-
ral holes with respect to the central one;
- Install the Ø 80 outlet flange on the central hole of the boiler, ta-
king care to insert the gasket supplied with the kit and tighten
by means of the screws provided;
- Install the plug on the left hole and the diaphragm on the right
hole 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 fe-
male end (with lip seal) of the Ø 80 flange unit to the end stop.
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 flaps
- Fit the male end (smooth) of the exhaust pipe into the female
end of the 90° Ø 80 bend, making sure that the relevant wall sea-
ling plate is already fitted; this will ensure hold and joining of
the elements making up the kit.
Max. length of exhaust duct.
The exhaust duct can be extended for horizontal installation, up to
a maximum length of 6.5 m straight, whereas for vertical installa-
tion, up to 8 m straight.
Coupling of extension pipes.
To install push-fitting 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.
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 and Ø 80/125 concen-
tric intake/ exhaust kits. Refer to the paragraph on indoor instal-
lation.
In this configuration the upper cover kit guarantees additional
protection for the boiler. It is recommended but not compulsory.
The Ø 80/80 separating device cannot be used in this configura-
tion (coupled with the cover kit).
