Stoves of the "Hermetic" series
If a pellet stove in the "Hermetic" series is installed,
alternatively it is possible to:
- channel the combustion air using a coaxial exhaust
pipe for the expulsion of the flue gases and air
withdrawal; therefore it is not necessary to create
a classic air intake in the room (fig. 5.5 A,B = Air
inlet C,D = Flue gas outlet);
- connect the stove's combustible air inlet to the air
intake with a suitable duct (fig. 5.6).
5.5 FLUE GAS EXHAUST PIPE
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 chimney, 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
pipe.
On the first T, at the exit of the flue gas outlet of the
stove, it is necessary to connect a pipe at the bottom
in order to evacuate any condensate that may form in
the chimney (Fig. 5.7a).
The horizontal sections must have a maximum length
of 2-3 m with an upward 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 draught valves.
The exhaust of the combustion products must be
provided on the roof.
Stoves of the "Hermetic" series
If a pellet stove in the "Hermetic" series is installed, it
is possible to use a specific coaxial pipe that allows
both the expulsion of flue gases and the ducting of the
combustion air from the outside (fig. 5.5 A,B=Air inlet
C,D=Flue gas outlet).
