For coaxial systems, the maximum flue lengths
listed in the table (see page 3) take into account
an elbow.
For twin flue systems the maximum flue lengths
listed in the table (see page 3) includes the exhaust
gas/air intake terminal.
Type 5 outlets should respect the following instruc-
tions:
1- Use the same ø 80 mm flue pipes for the air
intakes and exhaust gas ducts.
- If you need to insert elbows in the air intake and
exhaust gas ducts, you should consider for each
one the equivalent length to be included in the
calculation of developed length.
3- The exhaust gas duct should jut above the roof by
at least 0.5 m.
4- The intake and exhaust gas ducts in Type C13
and C53 must be installed on the same wall, or
where the exhaust is vertical and the air intake
horizontal, the terminals must be on the same
side of the building.
