Coupling of extension pipes.
To install push-fitting extensions with other elements of the
fl
ue,
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.
Th
is will ensure sealing e

ciency
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 up-
per cover kit guarantees additional protection for the boiler. It is
recommended but not compulsory.
Th

80/80 separating device
cannot be used in this configuration (coupled with the cover kit).
1.13 OUTDOOR INSTALLATION IN PARTIALLY
PROTECTED AREA.
A partially protected location is a place where the
appliance is not exposed to the direct effects of the
weather (rain, snow, hail, etc.).
If the appliance is installed in a place where the am-
bient temperature drops below 0°C, use the optional
antifreeze kit, checking the ambient operating tem-
perature 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. 11) and
fl
ue gas exhaust in a single chimney or directly
outside. In this configuration it is possible to install the boiler
in a partially protected 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
fl
ue 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
).
Th
e technical regulations in force must be respected.
