Flue Gas Fitting - Palazzetti Royal Ecofire LEA Installations Und Wartungsanweisung

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 direc-
tion changes, in addition to that resulting from
the rear connection of the appliance to the
chimney, using 45 - 90° bends or Tee fittings
(Fig. 20 - Fig. 21).
Always use a Tee fitting with inspection cap at
each horizontal and vertical change of the flue
gas route (Fig. 20 - Fig. 21).
The horizontal sections must have a maximum
length of 2-3 m with an upward slope of 3-5%
(Fig. 20 - 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.
