For coaxial systems, the maximum development
value, mentioned in the table below also takes into
account an elbow.
For twin flue systems the maximum development
value, mentioned in the table includes the exhaust
gas/air intake terminal.
Type 5 outlets should respect the following
instructions:
1- Use the same ø 80 mm flue 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 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 5 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.
There are some different types of flue systems shown on Page 20.
For additional information regarding the flue accessories, please
consult the Flue Pipe Accessories manual.
