FLUE SYSTEM
((Fumes duct, flue and chimney pot
Fumes duct, flue and chimney pot))
Thsi chapter has been drawn up pursuant to European
regulations EN 13384, EN 1443, EN 1856 and EN
1457. The installer must observe both these and any
other local regulations. This manual does not in any
way substitute such regulations.
The product must be connected to a flue system which
ensures that the fumes produced by combustion are
exhausted in complete safety.
Before positioning the product, the installer must
check that the flue pipe is properly rated.

The fumes duct (which connects the hearth's fumes
(which connects the hearth's fumes
outlet with the flue)
outlet with the flue) and the flue itself must, among
other regulatory requirements:
• receive the fumes from a single product (the outlets
of multiple appliances may not be conveyed into
a single flue)
• be routed vertically for the most part
• have no downwards sloping sections
• preferably have a circular internal cross section, or
with a ratio of the sides of less than 1.5
• terminate at roof level with a proper chimney pot:
the flue may not discharge directly from the wall
or into an enclosed space, even if the space in
question is open to the sky
• be made of material rated fire reaction class A1 per
UNI EN 13501 or analogous national regulations.
• be certified, with a chimney plate if metal
• be of uniform cross section or vary in cross section
only immediately after the outlet, not at some mid
point of its length
THE FUMES DUCT
THE FUMES DUCT
Further to the general prescriptions for the fumes duct
and flue, the fumes duct::
• may not be made of flexible metal material
• must be insulated, if routed through unheated
areas or outdoors
• must not be routed through rooms in which the
installation of combustion heat generators is
prohibited, or subject to fire hazard, or which
cannot be inspected.
• must enable the recovery of soot and be open for
inspection
• must have at most 3 bends, through an angle of
no more than 90°
• must have a single horizontal section of length
no more than 3 metri, depending on the draw.
Note in any case that long sections promote the
accumulation of dirt and are harder to keep clean.
Avoid infiltration of condensate water
through the flue. If necessary, mount an
anti-condensate ring – ask your chimney
sweeper for details.
Damage caused by condensate water is
not covered by the warranty.
*
In some nations, installations with multiple
flues are permitted under certain conditions.
Depending on regional regulations,
additional safety systems are necessary in
case of connection to multiple flues. Your
chimney sweeper/technician will be able to
provide further details.
