1.20 OUTDOOR INSTALLATION IN PARTIALLY PROTECTED AREA
By partially protected area, we mean one in which the unit is not directly exposed to the elements (rain, snow, hail, etc.).
If the appliance is installed in a location where the ambient temperature falls below -5°C, use the optional antifreeze kit, check-
ing the ambient temperature range for operation in the technical data table in this instruction manual (Section 'Technical
Data').
Configuration type B, open chamber and fan assisted (B
Using the relevant cover kit, direct air intake is possible and flue gas is exhausted into a single flue or directly to the outside. In this config-
uration it is possible to install the appliance in a partially protected place. In this configuration the appliance 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 gas exhaust must be connected to its own single chimney (B
haust (B
) or via an Immergas ducting system (B
53
The technical regulations in force must be respected.
Cover kit assembly (Fig.17).
Remove the two plugs from the lateral intake holes. Now cover the left intake hole using the relevant plate, fixing it onto the right side us-
ing 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 exhaust pipe (both vertical or horizontal) can be extended to a max. length of 45 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 appliance).
By leaving the side plugs fitted, it is possible to install the appliance externally, in a partially covered place, 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 top cover kit that guarantees additional protection for the appliance is recommended but not compulsory.
