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 obstruct the boiler intake/exhaust terminal, even temporarily.
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 1.5% towards the boiler must be maintained, and a section clip
with pin must be installed every 3 metres.
All boilers have an experimentally obtainable maximum Resistance Factor (R) equal to 100.
