Combustion air ducting kit (optional)
The use of this kit significantly facilitates the
direct ducting of the external combustion air into
the firebox.
6.5 Flue gas fitting
The appliance works with the combustion cham-
ber at negative pressure. It is therefore essential
to make sure that the flue gas evacuation is
airtight (this is the responsibility of the installer).
The appliance must be connected to its own flue
gas duct, not shared, and which is suitable for
ensuring adequate dispersion of the combustion
products into the atmosphere, in accordance
with the regulations in force in the country of
installation.
The components making up the flue
gas ducting system must be declared
suitable for the specific operating con-
ditions and provided with CE marking.
It is mandatory to create a first vertical
section measuring at least 1.5 meters to
guarantee correct expulsion of the flue
gases.
It is advisable to make a maximum of 3 direction
changes, in addition to that resulting from the
rear connection of the appliance to the chimney,
using 45 - 90 ° bends or Tee fittings (Fig. 21).
Always use a T-pipe fitting with an inspection
cap (A) at each horizontal and vertical change of
the flue gas route (Fig. 21).
The horizontal sections must have a maximum
length of 2-3 m with an upward slope of 3-5%
(Fig. 21).
Anchor the pipes with suitable collars to the wall.
The flue gas fitting MUST NOT BE connected:

• to a chimney used by other generators (boilers,
stoves, fireplaces, etc. ...);
• to air extraction systems (hoods, vents etc. ...)
even if "ducted".
It is forbidden to install shut-off and draught
valves.

With a flue gas discharge path of more
than 5 meters and in conditions of
poor draft (presence of many curves,
inadequate exhaust terminal, etc.) the
expulsion of fumes may not be the
best. In these cases, it will be necessary
to change the operating parameters
(fume expulsion and pellet loading) to
adapt the appliance to the actual in-
stallation characteristics of the flue.
In this regard, please contact the tech-
nical assistance service.
