5.3 FLUES AND CHIMNEY CAPS

The chimney must be dimensioned in compliance
with EN 13384-1.
Follow the indications in the technical data sheet
relating to the chimney draught.
The flue pipe for the discharge of smoke must be
compliant with standards EN 10683, EN 1856-1-2,
EN 1857, EN 1443, EN 13384-1-3, EN 12391-1,
EN15287-1 both in terms of size and materials used
to construct it.
• The soot fire resistance class of the chimney must
be at least T400.
• A PERFECT DRAUGHT is above all the result
of a flue that is clear of obstructions such as
chokes, horizontal sections or corners; any axial
displacements should be at a maximum angle of
45° compared to the vertical axis, (better still if it is
only 30°). These displacements should preferably
be effected near the chimney top.
• THE SMOKE PIPE between the fireplace and
the flue pipe must have the same cross-section
as the appliance's smoke outlet. The smoke pipe
must be sealed. It is prohibited to use extendable
flexible metal pipes. To connect the appliance to the
chimney, you may perform a maximum of 3 direction
changes no greater than 90°, with the smoke pipe
no longer than 2 m in horizontal projection and a
maximum of 3 total meters. Make sure that the first
vertical segment is at least 50 cm before changing
direction.
• The CHIMNEY TOP shall be the WINDPROOF type
with an inside cross section equivalent to that of the
flue and with a smoke outlet passage section at least
DOUBLE the internal one of the flue.
• Backflow area: The outlet must be outside of the
backflow area calculated according to figure 5.2
and relative table. Near the ridge cap, consider the
less of the two.
• If there are obstacles on flat roofs, to position the
chimney respect the distances and measurements
according to figure 5.3 and relative table.
If the fireplace is installed with a flue that has already
been used it should be cleaned thoroughly to avoid
malfunctions and the danger of unburned parts
deposited on the inside from catching fire.
