1.14 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. 13)
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 environment 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, positioning 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

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.
