1.12 INTERNAL INSTALLATION USING
A RECESSED FRAME WITH DIRECT
AIR INTAKE
• Configuration type B, open chamber and
forced draught.
Using a kit separator one can achieve direct air
intake (Fig. 1-12) and fumes exhaust in a single
flue or directly outside. In this configuration the
boiler is classified as type B .

With this configuration:
- air intake takes place directly from the envi-
ronment in which the appliance is installed
(the recessed frame is ventilated), and only
functions in permanently ventilated rooms;
- the flue exhaust must be connected to its own
individual flue or channeled directly into the
external atmosphere.
The technical regulations in force must be
respected.
Separator kit installation: install the discharge
flange on the central hole of the boiler, posi-
tioning the relative gasket with the circular
projections downwards in contact with the
boiler 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, positioning its gasket
already present in the boiler 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
boiler.
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 30 linear metres.
