6.3 Fume exhaust
In conformity with DPR 412 and UNI
7129-2001, the allowed installations are:
WITH VERTICAL EXTERNAL OR INTERNAL
FLUE
• The Fig. 3 represents the best solution for
discharging the fumes above the roof.
Proceed as in previous chapter with the
installation of a T-fitting with an inspection
plug. The external or internal flue must
be properly fixed and provided with a
chimney pot for protection from rain.
FUME DISCHARGE THROUGH A CHIMNEY
• Fig. 4 is the classic masonry chimney
system, of course in addition to Fig.1).
Use a T-pipe with an inspection plug and
suitable supporting staffs.
If the chimney is too big, we recommend
reducing it by inserting a porcelain steel
pipe or stainless steel (inox), with a
maximum diameter of 150 mm, and
appropriately sealing the fume inlet and
outlet parts of the fume exhaust from the
part in masonry.
