The maximum permissible flue length for twin flue is dependent on the type of run used (see table below).
For further information relating to flue runs not illustrated, please contact the Technical Department on 0870 241 8180.
For coaxial systems, the maximum flue lengths listed in the table below take into account an elbow.
For twin flue systems the maximum flue lengths listed in the table below 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 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.
