Positioning the gaskets (black) for "green range" flue systems.
Position the gasket correctly (for bends and extensions) (Fig. 12):
- gasket (A) with notches, to use for bends;
- gasket (B) without notches, to use for extensions.
If necessary, to ease the push-fitting, spread the elements with commonly-used talc.
Extension pipes and concentric elbows push-fittings.
To install push-fitting extensions with other elements of the flue, proceed as follows:
- Install the concentric pipe or elbow with the male side (smooth) on the female side (with lip seal) to the end stop on the previously in-
stalled element in order to ensure sealing efficiency of the coupling.
If the exhaust terminal and/or extension concentric pipe needs shortening, consider that the internal duct must always pro-
trude by 5 mm with respect to the external duct.
For safety purposes, do not even temporarily obstruct the appliance intake/exhaust terminal.
The various parts of the flue system must be checked to ensure that they have been laid in such a
way as to prevent the coupled parts from detaching, in particular, the flue exhaust duct in the
Ø80 separator kit configuration. If the condition described above is not adequately guaran-
teed, it will be necessary to use the appropriate retaining clamp kit.
When installing horizontal pipes, a minimum inclination of 5% towards the appliance must be maintained, and a section
clamp with plug must be installed every 3 metres.
