1.6 INSTALLATION OUTSIDE IN A
PARTIALLY PROTECTED PLACE.
N.B.:
a partially protected location 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.
The relevant terminal must be used for this
configuration (present in the intake kit for the
installation in question), which must be placed
on the central hole of the boiler (see following
figure). Air intake takes place directly from the
environment in which the boiler is installed
and fumes are expelled in an individual flue or
directly to the outside.
The boiler in this configuration is classified as
type B22 according to the standards.
With this configuration:
- air intake takes place directly from the
environment in which the boiler is installed
and only functions in permanently ventilated
rooms
- the fumes pipe must be connected to its own
individual flue or channelled directly into the
external atmosphere.
The technical regulations in force must be
respected.
• Fitting the cover kit. (Fig. 1-10) Remove the
two plugs and the seals present from the two
holes to the laterally to the central one.
Install the Ø 80 outlet flange on the central
hole of the boiler, taking care to insert the seal
supplied with the kit and tighten by means
of the screws provided. Install the top cover,
fixing it with the screws previously removed
from the lateral plugs. Engage the 90°, Ø 80
bend with the male end (smooth) in the female
end (with lip seal) of the Ø 80 flange until it
stops. Cut the seal in the relative groove at the
desired diameter (Ø 80), run it along the bend
and fix it using the sheet steel plate. Insert the
exhaust pipe with the male end (smooth) into
the female side of the 90° bend, Ø 80, making
sure that the relative washer has already been
introduced. This will ensure tightness and
coupling of the elements making up the kit.
Max. length of exhaust flue.
The flue pipe (ver-
tical or horizontal) can be extended to a max.
length of 12 m straight route, using insulated
pipes (Fig. 1-28). To prevent problems of fume
condensate in the exhaust pipe Ø 80, due to fume
cooling through the wall,
the length of the pipe
must be limited to just 5 m (Fig. 1-25).
•
Coupling of extension pipes and elbows. To
install possible coupling extensions on other
fume extraction elements, proceed as follows::
Fit the male end (smooth) of the pipe or elbow
up to the stop on the female end (with lip seals)
of the previously installed element; this will
ensure correct seal and joining of the elements.
Example of installation with direct vertical
terminal in partially protected locatio. When
the vertical terminal for direct discharge of
combustion fumes is used, a minimum gap of
300 mm must be left between the terminal and
the balcony above. The distance A + B (always
with respect to the balcony above), must be equal
to or less than 2000 mm (Fig. 1-9).
• Configuration without cover kit in a partially
protected location (boiler type C).
By leaving the side plugs fitted it is possible
to install the appliance externally without the
cover kit. Installation is carried out using the
horizontal concentric Ø60/100, Ø80/125 and
Ø80/80 separator kits.
