1.19 OUTDOOR INSTALLATION IN PARTIALLY
PROTECTED AREA.
A partially protected area is one in which the indoor
unit is not exposed to the direct action of the weather
(rain, snow, hail, etc.).
If the indoor unit is installed in a place where the
ambient temperature drops below -5 °C, use the op-
tional antifreeze kit, checking the ambient operating
temperature range shown in the technical data table
in this instruction booklet.
Configuration type B, open chamber and fan assisted.
(B
23
or B
53
).
Using the special coverage kit one can achieve direct air intake (Fig.
16) and flue gas exhaust in a single chimney or directly outside.
In this configuration it is possible to install the indoor unit in a
partially protected place. In this configuration the indoor unit is
classified as type B.
With this configuration:
- air intake takes place directly from the environment in which
the indoor unit is installed (external);
- the flue gas exhaust must be connected to its own single chimney
(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.
Cover kit assembly (Fig. 18).
Remove the two plugs and the gaskets present from the two lateral
holes with respect to the central one. Now cover the left intake
hole using the relevant plate, fixing it onto the right 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 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 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 30 linear metres.
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 concentric intake/ exhaust kits. Refer to
the paragraph on indoor installation. 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 configuration (coupled with the cover kit).
