installation
For coaxial systems, the maximum ue lengths,
mentioned in the table on page 28 also take into
account an elbow.
For twin ue systems the maximum ue length,
mentioned in the table includes the exhaust gas/air
intake terminal.
Twin ue outlets should respect the following
instructions:
1- Use the same ø 80 mm ue pipes for the air
intakes and exhaust gas ducts.
2- 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
ue length calculation.
3- The exhaust terminal should jut above the roof by
at least 0.5 m.
4- The intake and exhaust gas ducts in Type C13 +
C53 must be installed on the same wall, or where
the exhaust is vertical and the air intake horizon-
tal, the terminals must be on the same side of the
building.
