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uegases
and air withdrawal; therefore it is not necessary
tocreateaclassicairintakeintheroom(g.
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(g.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ue
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ue system
mustbedeclaredsuitableforthespecicoperating
conditions and provided with CE marking.
 Itismandatorytocreatearstverticalsectionofa
minimum 1.5 meters to guarantee correct expulsion
oftheue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-ttings(g.5.7).
  Always use a T-tting with an inspectioncap at
each horizontal and verticalvariation of theue
gas exhaust pipe.
OntherstT,attheexitoftheue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%(g.
5.7).
Anchor the pipes with suitable collars to the wall.
  TheuegasexhaustconnectionMUSTNOTbe
connected:
- to a chimney used by other generators (boilers,
stoves,replaces,etc.);
- to air extraction systems (hoods, vents, etc.)
even if “intubated”.
  Itisforbiddentoinstallshut-o󰀨anddraughtvalves.
The exhaust of the combustion products must be
provided on the roof.
