Flue Gas Exhaust Pipe - termovana Anna Manuel D'utilisation

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 works with the combustion chamber in a
vacuum, therefore it is essential to ensure the flue
gas exhaust pipe is properly sealed.
The stove must be connected to its own dedicated
flue system, suitable in ensuring the proper
dispersion of the combustion products in the
atmosphere.
The components that make up the flue 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 flue gases.
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 flue gas exhaust connection MUST NOT be
connected:
- to a chimney 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.
