THE SMOKE CHANNEL
• if in metal must have a CE marking (EN 1856-2) or
similar national law;
• cannot be in fl exible metal material
• to check the fl ow, a shutter is advised for draft over
25 Pa
THE CHIMNEY FLUE:
• must have a draft capable of creating negative
pressure ideally around 12 Pa. Lower drafts can
cause leaking smoke if the door is open; higher
values tend to generate fast combustion by
reducing the yield
• must be correctly sized to meet smoke evacuation
(EN 13384-1)
• must preferably be insulated, in steel with a circular
inner section. If rectangular, the inner edges must
have a radius under 20 mm and a ratio between
between the inner dimensions <1.5
• normally have a minimum height of 3-4 metres
• maintain a constant section
• be waterproof and thermally insulated to guarantee
draft.
• preferably create a collection chamber for
unburned fuel and any condensate
• beat least category T400, with an adequate
resistance to soot fi reIf pre-existing, it must be
cleaned to avoid risk of fire.
THE CHIMNEY STACK
12 • must be wind-proof
• have an internal section equivalent to that of the
chimney flue and passage section outlet equal to
at least double the inner passage of the chimney
flue
• for paired chimney flues (which should be at least
2 m apart) the chimney stack of the chimney flue
receiving the product discharge with solid fuel or
that of the highest fl oor must be at least 50 cm
taller
• must go beyond the refl ux zone
• must enable chimney maintenance
INSTALLATION
EXTERNAL AIR INTAKE (Figs. A-B)
The connection with the outside, made with a cross-
sectional area of at least 80/200 cm² (depending on
the model) is absolutely essential, as prescribed by
the standard governing installation requirements (UNI
10683).
It must, therefore, be provided.
It is made with a duct that must bring outside air
directly to the adjustment mechanism (Fig. B). The
regulation mechanism must be attached to the bottom
of Firebox .
®
During installation, carefully seal the points where the
external air may leak.
The external air duct may come from behind, from
below, from the side, or consist of a fl exible hose
which runs directly from the outside to the mechanism
vent (Fig. B).
It is advisable to apply a protection grille on the outside
of the air-intake duct that does not, reduce the air-fl ow
capacity.
The external air must be drawn in at floor level.
If it is not possible to do as described above, place the
external air intake as near to Firebox as possible.
