3.10 - FLUE OUTLET CONNECTION
The flue system must be installed in accordance with the local
regulation and national codes of practice.
The chimney is of fundamental importance for the correct boiler
operation: it is therefore necessary that the chimney is imper-
meable and properly insulated.
Old or new chimneys, built without respecting the specific
requirements can be recovered by “tubing” the chimney itself.
It will be necessary to introduce a metallic pipe inside the existing
chimney and insulate the space between the metallic pipe and
the chimney.
Chimneys made of prefabricated blocks must have perfectly
sealed joints to avoid that flue condensate smudge the walls
due to permeation.
The entrance to the chimney should be with an angle of 45°.
At the base of the chimney a flue inspection opening has to be
made.
It is advisable to insulate the flue pipe connecting the boiler to
the chimney in order to reduce the heat losses and noise.

We recommend using only flue pipes
suitable
to the type of fuel used.
Damages caused by installation errors and for
non-observance of the instructions given by
the same manufacturer will invalidate all the
supplier’s contractual or extra contractual
responsibilities.
The flue outlet has to meet the latest regulations in force.
