1.20 INTERNAL INSTALLATION USING A RECESSED
FRAME WITH DIRECT AIR INTAKE.
• Configuration type B, open chamber and fan assisted.
Using a kit separator one can achieve direct air intake (Fig. 20)
and flue gas exhaust in a single chimney or directly outside. In this
configuration the indoor unit is classified as type B
23
.
With this configuration:
- air intake takes place directly from the environment in which
the indoor unit is installed (the recessed frame is ventilated),
and only functions in permanently ventilated rooms;
- the flue gas exhaust must be connected to its own individual
chimney or channelled directly into the external atmosphere.
The technical regulations in force must be respected.
Separator kit installation (Fig. 19):
Install the discharge flange on the central hole of the indoor
unit, positioning the relative gasket with the circular projections
downwards in contact with the indoor unit flange and tighten
using the hex screws with flat tip contained in the kit. Remove the
flat flange present in the lateral hole with respect to the central one
(according to needs) and replace it with the intake flange, positio-
ning its gasket already present in the indoor unit and tighten using
the supplied self-threading screws. Fit the male side (smooth) to
the bends in the female side of the flanges.
The intake bend must face the rear side of the indoor unit.
Fit the exhaust pipe with the male side (smooth) to the female
side of the bend up to the end stop, making sure that the internal
wall sealing plate has been fitted and connecting the required flue
according to personal requirements.
Max. length of exhaust duct.
The flue pipe (both vertical or horizontal) can be extended to a
max. length of 36 linear metres.
