TWIN PIPE
SYSTEMS
FIG. 2.11
In calculating the lengths of the pipes, the
maximum length “L” must also take into
consideration the values for the
exhaust/air intake end terminals, as well
as 90° elbows for coaxial systems.
The C52 types must comply with the
following requirements:
1 - The exhaust/ air intake pipes must
have the same diameter of
ø 80 mm.
2 - If elbows are to be inserted into the
air intake and/or exhaust system, the
calculation of the overall length must
take into consideration the values for
each elbow, see the
FLUE PIPE
ACCESSORIES MANUAL.
3 - The exhaust pipe must protrude by at
least 0.5 m above the top of the roof
in the event that it is located on the
opposite side to the side with the air
intake (this condition is not obligatory
when the air intake and exhaust are
located on the same side of the
building).
