7.5. Smoke evacuation duct
The smoke discharge from the stove is with
positive pressure in relation to the surrounding
environment, so it is essential to guarantee the
tightness of the different joints of the chimney.
The smoke evacuation duct must be independent
from other equipment.
To guarantee the correct extraction of the smoke,
it is mandatory that the first section of the
chimney be vertical with a height of not less than
1.5 meters.
The horizontal sections must not be longer than
1.5 meters with a slope of at least 5%.
The chimney outlet must comply with EN 1856-2
for built-in masonry chimneys and EN 1856-1 for
insulated outdoor chimneys. It must be in 0.5mm
thick 316 stainless steel with dimensions
respecting what is indicated in the equipment
characteristics, regarding the smoke outlet.
The smoke duct must have a diameter of 80 mm,
with male/female joints fitted with a high-
temperature silicone gasket (>200ºC) with
inverted installation (male downwards) to
prevent condensation from flowing out of the
chimney.
For chimneys over 5 meters high, their section
must change to a diameter of 100 mm after 5
meters. The dimensioning of the smoke duct must
be done considering 0 P
a.
The piping used outdoors must be in double-
walled stainless steel, in order to avoid
condensation and corrosion of the same, resulting
from the thermal shock.
It is forbidden to install dampers, butterflies or
valves that strangle the chimney's draft capacity.
The fume exhaust capacity depends on several
factors, including the height of the chimney.
Depending on these factors, it may be necessary
to make adjustments to the stove's operating
parameters. Excess draft when it is not possible
to correct it by changing parameters such as air
intake and pellet loading, it will imply the
installation of an air intake valve to the chimney.
If necessary, contact the technical assistance
service.
7.5.1. Basic requirements
Below are some proposals for the execution of a
chimney, which should be understood as
schemes, not replacing a specialty project.
