Fume Exhaust - CASATELLI LEONARDO 8ET Generalidades - Advertencias - Instalación - Mantenimiento

"Hermetic" series installation
In this case the following is possible as an
alternative:
- channel the combustion air using a coaxial
exhaust pipe for the expulsion of the fumes
and withdrawal of the air; therefore, it is not
necessary to create a classic air intake in the
room (Fig. 5.5 A,B = Air inlet C,D = Fumes
outlet);
- connect the stove combustion air inlet to the air
inlet with a suitable pipe (Fig. 5.6).

5.5 FUME EXHAUST

The stove operates with the negative pressure in
the combustion chamber and so, it is essential to
ensure that the fume outlet is leak-proof.
The stove must be connected to its own exclusive
fume discharge system which can adequately
disperse the combustion products into the
atmosphere.
The components that make up the smoke
evacuation system must be declared suitable for
the specific operating conditions and provided with
CE marking.
It is mandatory to create a first vertical section of a
minimum 1.5 meters to guarantee correct expulsion
of the fumes.
It is advisable to make a maximum of 3 changes
of direction, in addition to that resulting from the
rear connection of the stove to the fireplace, using
45-90° bends or T-fittings (Fig. 5.7).
Always use a T-fitting with an inspection cap at
each horizontal and vertical variation of the flue
gas exhaust path.
The horizontal sections must have a maximum
length of 2-3 m with an upwards slope of 3-5% (Fig.
5.7).
Anchor the pipes with suitable collars to the wall.
The fume exhaust connection MUST NOT be
connected:
- to a fireplace used by other generators (boilers,
stoves, fireplaces, etc.);
- to air extraction systems (hoods, vents, etc.)
even if "intubated".
It is forbidden to install shut-off and draft valves.
The exhaust of the combustion products must be
provided on the roof.
