Roof flue exhaust kit (Fig. 6.12)
Coaxial pipe Ø 80/125 mm with a nominal
height of 0.96 m.
This kit exhausts directly to the roof.

Extensions are available for reaching the
maximum height.
Its maximum height with extension is 10 m.
Bends of Ø 80 mm at 90° and at 45° are
available that reduce the maximum total
length of the pipes by:
For the bend of 45° loss
For the bend of 90° loss
Pluming kit A (Fig. 6.13)
Co-axial ø 60/100 mm + vertical part ø 60
mm (flue outlet).
This kit allows the combustion air to be
sucked up and expel the burnt gases di-
rectly to the outside through a telescopic
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.
Maximum equivalent length "a+b" (Fig.
6.13) of 15 metres can be achieved utilising
extensions.
Each additional elbow reduces the overall
acceptable length of the flue system as fol-
lows:
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.
Pluming kit B (Fig. 6.14) (Fig. 6.15)
