1.14 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. 17)
and flue gas exhaust in a single chimney or directly outside.
In this configuration the boiler is classified as type B22.
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 gas exhaust must be connected to its own individual
chimney and channelled directly into the external atmosphere.
The technical regulations in force must be respected.
Separator kit installation (Fig. 16).
1. 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.
2. 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 boi-
ler and tighten using the supplied self-threading screws.
3. Fit the bends with male side (smooth) in the female side of the
flanges (the intake bend should face the rear side of the boiler).
4. 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 inter-
nal wall sealing plate has been fitted and connecting the requi-
red flue according to personal requirements.
Max. length of exhaust duct.
The exhaust pipe (both vertical or horizontal) can be extended to a
max. length of 27 linear metres.
