INsTALLATION INsTRUcTIONs
smoke channel
The conduit which connects the hearth smoke
outlet mouth with the flue inlet is called
smoke channel.
The smoke channel must be made with stiff
steel or ceramic pipes, flexible metal or fibre-
cement pipes are not allowed.
Horizontal or counterslope tracts must be
avoided.
Eventual section changes are allowed only at
the chimney outlet and not, for example, at
the coupling in the flue.
Slants of more than 45° are not allowed.
A mastic sealing at high temperature must
be carried out in correspondence of the inlet
point of the steel flue on the chimney smoke
outlet mouth.
Further to the above, bear in mind
the indication of the UNI 10683/2005
rule in paragraph 4.2 „connection to
the smoke evacuation system" and
sub-paragraphs.

Flue and chimney pot
The conduit which, from the room with the
chimney reaches the building covering, is
called flue.
The fundamental features of the flue
are:
- capability to support a smoke temperature of
at least 450°C with regard to the mechanical
resistance, insulation, and gas hold
- being correctly insulated to avoid the forming
of condensation
- have constant section, almost vertical flow
and not slant more than 45°
- have preferably circular internal sections; in
case of rectangular sections, the max. ratio
between the sides must not exceed 1.5
- have an internal section with a surface at
least equal to the one reported on the technical
board
- service only one hearth (chimney or stove).
Piping using stainless steel
appropriate size and ideal insulation is
suggested for flues which are old or too
large.
The chimney pot fundamental
features are:
- basic internal section equal to the one of
the flue
- outlet section not less than double that of
the flue
- position in full wind, above the roof and
outside the reflux areas.
