Flue Gas Fitting; Roof Exhaust With Traditional Fireplace - Palazzetti ECOFIRE TWIGGY Notice D'installation Et D'entretien

If one or more extraction fans (extrac-
tor hoods) are present and operating
in the installation room, combustion
malfunctions may occur due to lack of
combustion air.

5.5 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 gas
flue, not shared, and which is suitable for ensur-
ing adequate dispersion of the combustion prod-
ucts into the atmosphere, in accordance with the
regulations in force in the country of installation.
The components that make up the gas
flue evacuation system must be de-
clared suitable for the specific operat-
ing conditions 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. 10).
Always use a Tee fitting with inspection cap at
each horizontal and vertical change of the gas
flue path (B - Fig. 10).
The horizontal sections must have a maximum
length of 2-3 m with an upwards slope of 3-5%
(Fig. 10).
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.

5.6 Roof exhaust with traditional
fireplace
The chimney for the evacuation of flue gases
must be made by qualified personnel in compli-
ance with standards UNI 10683- EN 1856-1-2- EN
1857-EN 1443- EN 13384-1-3- EN 12391-1 both in
terms of the dimensions and the materials used
in its construction.
The discharge of fumes through a traditional
fireplace (Fig. 11th upper smoke outlet -
Fig. 11b rear smoke outlet) can be performed
provided the maintenance status of the chimney
is checked. In the case of an old chimney, it is
advisable to renew it using ducting.
The exhaust of the combustion products must
be provided on the roof.
