Fumes evacuation system
The stove must be connected to a fumes evacuation
system suitable to ensure an adequate dispersion into the
atmosphere of the combustion products, in compliance
with standards EN 1856-1-2 EN 1857, EN 1443, EN
13384-1-3, EN 12391-1, UNI 10683 both for size and
for the materials used in its construction.
T h e s i z e o f t h e c h i m n e y s h o u l d b e i n
accordance with what reported in the Technical
Sheet (average draft 12 Pa with door closed).
The components of the systems for the evacuation
of combustion products must be declared adequate
for the specific operating conditions and provided
with marking
.
The section of the flue will remain constant for the whole
of its height.

Obsolete flues, built with unfit material are outlaw and
jeopardise the proper functioning of the stove.
The flue system must be provided with its own grounding
connection in accordance with the UNI 10683.
A perfect draft is given mainly by a flue free from
obstacles such as bottlenecks, horizontal paths, corners;
any displacements of the axis must have an inclined
path with a max angle of 45° with respect to the vertical,
better still if only 30°.
The chimney must be wind proof with internal section
equivalent to the one of chimney and the passage section
of the exhaust smoke at least twice the one inside the
chimney.
Each firebox should have its own independent fumes
evacuation system.
If the chimney that you want to use for the installation
was previously connected to other stoves or fireplaces, it
is necessary to carry out a thorough cleaning in order to
prevent anomalous operations and to avert the danger of
fire of the unburned matter deposited on the inner walls
of the chimney.
Pay particular attention to the passage of the fumes
system through wood roofs or walls for which it is
necessary to use special certified components.
