5.5.1 FLUE GAS CHANNEL
The flue gas channel consists of the various components that con-
nect the appliance to the flue, and allows for adequately dispersing
the combustion by-products into the atmosphere.
l
The flue gas channel must be made by qualified per-
sonnel in accordance with the regulations in force;
in particular, it must guarantee the minimum draught
specified by the appliance's manufacturer and be
suitably sealed.
The components making up the flue gas channel
■
must be declared suitable for the specific operating
conditions of the appliance to be installed and must
be suitably sized in relation to it.
a
Refer to the manufacturer's indications and designa-
tion with regard to: the safety clearances, installation
procedure, maintenance, safety and insulation of the
elements used to make the flue gas channel.
Be careful that the flue gas channel does not come
■
into contact with heat-sensitive or combustible
materials (for example fabrics, clothing, claddings,
walls, wooden beams or ceilings, etc.).
If wooden roofs or walls must be crossed, it is man-
■
datory to use appropriate certified kits, available in
retail stores.
If there is a risk of accidental contact with the flue
■
gas channel, adequately protect the external sur-
face as indicated by the manufacturer of the flue gas
channel elements and according to the regulations
in force.
l
For detailed information on the position of your ap-
pliance's fume exhaust, consult the chapters

exhaust".
d
The flue gas channel must not cross rooms where
it is forbidden to install combustion appliances, nor
other rooms with a risk of fire or that cannot be in-
spected.
It is forbidden to install flexible pipes made of metal,
■
fibre cement, aluminium or pipes without CE approv-
al, and to use of counter-sloping elements.
d
The appliance must be connected to its own non-
shared fume exhaust duct, therefore the flue gas
channel MUST NOT be connected:
to a flue used by other appliances such as boilers,
■
stoves, fireplaces, etc.
to air extraction systems, such as hoods or purge
■
devices.

5.5.2 FLUE
Each product must be connected at a flue for discharging combustion
by-products to the outside, via natural draught.
l
The flue must be made by qualified personnel and
in accordance with the regulations in force, with re-
gard to both its dimensions and the materials used
to build it.
The flue must be suited to the specific operating
■
conditions of the appliance to be installed and must
be suitably sized in relation to it; in particular, it must
guarantee the minimum draught specified by the
appliance manufacturer and must be appropriately
sealed.
d
It is forbidden to make other flue gas or air extraction
channels, or pipes connected to plants, pass inside
the flue, unless otherwise specified by the manufac-
turer and allowed by the national standards and local
regulations.
It is important to bear in mind that:
- the flue must be equipped with a chamber for collecting solid ma-
terial and condensate; it must be situated under the fitting inlet, so
that it can be easily opened and inspected through an airtight door
(inspection for soot collection)
- if wooden roofs or walls must be crossed by piping, we recommend
using appropriate certified kits, available in retail stores
- the flue must have a maximum operating temperature and soot fire
resistance class corresponding to the type of fuel used and as indi-
cated in the table.

Fumes can be discharged through the existing flue,
after verifying that the flue has undergone proper
maintenance.
If the flue does not conform to the requirements, ei-
■
ther because it is too old or too large, assess with
qualified personnel whether to adapt it to the regula-
tions, for example by burying the flue in a stainless
steel pipe suitably insulated and sized according to
the path. Moreover, the connection to the flue must
be sealed.

The combustion by-products must be discharged
through the roof.

■
cial requirements in your area, refer to the local reg-
ulations.
