• Positioning of double lip seals.
For correct positioning of lip seals on elbows and extensions,
follow the assembly direction shown in the figure (Fig. 9).
• Coupling extension pipes and concentric elbows.
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 installed element in order to ensure
sealing efficiency of the coupling.
N.B.: if the exhaust terminal and/or concentric extension pipe
needs shortening, consider that the internal duct must always
protrude by 5 mm with respect to the external duct.
N.B.: 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 parti-
cular, the flue exhaust duct in the Ø80 separator kit
configuration. Should the aforesaid condition not be
adequately guaranteed, it will be necessary to use the
special clamp ring nut clip kit.
N.B.: during the installation of the horizontal pipes one must
maintain a minimum inclination of the pipes of 3% towards the
boiler and a section clamp with gusset must be installed every
3 metres for non-insulated pipes and one every 2 metres for
insulated pipes.
