co- axial flue (450-950 mm).

In the last section, the fumes are expelled
through a vertical section.
Extensions and elbows can be added to ex-
tend the kit's length.
The chart of Fig. 6.12 gives the allowable di-
mensions of the ducts "a" and "b" of Fig. 6.11.
Each additional elbow reduces the overall ac-
ceptable length of the flue system as follows:
45° (60/100 mm) reduce length by 0,5 m.
90° (60/100 mm) reduce length by 1 m.
45° (60 mm) reduce length by 0,65 m.
90° (60 mm) reduce length by 0,85 m.
