Flue gas fitting

The appliance works with the combustion chamber
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. 25 - Fig. 26).
Always use a Tee fitting with inspection cap at each
horizontal and vertical change of the flue gas route
(Fig. 25 - Fig. 26).
The horizontal sections must have a maximum length
of 2-3 m with an upward slope of 3-5% (Fig. 25 - Fig.
26).
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.
