5.5 FLUE OR CHIMNEY
We will use a flue or chimney to be able to remove the gases that are produced in the boiler during combustion to the
outside.
The responsibility for the works carried out for the flue
installation be carried out by qualified personnel (who are in possession of the

•
The smoke
evacuation system must be unique for each boiler (smoke outlet evacuations
with other appliances are not allowed).
•
The

verticality.
•
The internal section of the smoke evacuation duct should be uniform and preferably circular. In the event
that we had a square or rectangular section, the edges should be rounded with a minimum radius of 20 mm,
the curves will be regular and without discontinuities, ensuring that the deviations of the path refarding the axis are
not greater than 45°.
•
It is strictly forbidden to install valves or closures that may obstruct the passage of fumes.
•
It is necessary to avoid horizontal sections of chimney, since this most likely will get it dirty and requires a
more frequent cleaning of the ducts, in the event that it is inevitable there will be a minimum of upward inclination
and "T" will be installed in the changes of direction to provide cleaning access without having to disassemble all
the installation. The installation must be carried out in such a way as to ensure regular cleaning without the need
to dismantle the entire flue.
•
For the installation of the smoke duct, safety standards and minimum distances must be respected.
