3.10 - FLUE CONNECTION
To connect the flue gas exhaust pipe, local and national standards
must be respected (see Standards UNI-CIG 7129 point 4 and
7131 point 5).
The chimney is of the utmost importance for correct boiler
operation: it is therefore necessary that the chimney be
waterproof and properly insulated.
Old or new chimneys, built without respecting the specific
requirements, can be recovered by “piping” 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 at a 45° angle.
At the base of the chimney a flue inspection opening has to be
made.
It is recommended to insulate the pipe connecting to the chimney
to reduce heat loss and noise.

When performing replacement installations,
ALWAYS
replace the flue gas exhaust accessory as well.
The flue must comply with standards in force.
