3.3 CHIMNEY FLUE
When installing the chimney flue, the following provi -
sions must be applied.
• comply with the product standard EN 1856-1;
• it must be installed using materials suitable to
guarantee resistance to normal mechanical and
chemical stress, and have a correct insulation, to
avoid the formation of condensate, therefore it
must be hermetically insulated;
• have a mainly vertical state and
not be choked along its length;
• be correctly spaced using
air cavities and insulated from flammable
materials,
• the changes in direction must be
at most 2 and with an angle not exceeding 45°;
• the chimney flue inside the home must
however be insulated and can be inserted in
a cavity provided it complies with the relevant
piping standards;
• the smoke channel should be connected to the
chimney flue using a “T” joint with an inspectionable
collection chamber for collection of fuel residue
and, in particular, for condensate collection.
It is not possible to connect the appliance to a
chimney flue shared with other combustion appli -
ances or in the presence of hood exhausts.
It is forbidden to use direct wall discharge or
towards closed spaces or any other form of dis-
charge not planned by legislation in force in the
country of installation (In Italy, only roof discharge is
permitted)
3.4 CHIMNEY STACK
The standard UNI 10683 states the stack must meet
the following characteristics:
• the smoke outlet section must be at least
double the inner section of the chimney;
• shaped to prevent
water or snow penetration;
• be built in such a way that wind
cannot affect the smoke outlet
(wind-proof cap);
• the opening measurement, which is measured
between the lower coverage protective layer
and the lower point of the
smoke outlet section into the atmosphere, must be
outside the back draught area;
• Be built far from antennas or
satellite dishes and must never be used as a
support.
You are advised to check the safe distances which
must be complied with in the presence of
combustible materials and the type of insulating
material to use (data available directly on the
chimney flue plate)
3.5 HERMETIC PRODUCT INSTALLATION
In the event of installation of a hermetic product,
you can execute one of the following types of con-
nection with the piping:
• smoke discharge (1) and recovery of oxidising air
directly from outside (2)

• smoke discharge (1) and oxidising air channelling
(2) taking advantage of its coaxial discharge
to expel the smoke and pick
the air; therefore, installation is not necessary
of a grate to recirculate the air
inside the premises where the
the product.
For coaxial installation or air sampling directly from
the outside, it is recommended not to exceed
2.5 / 3 linear meters in order to ensure correct
oxygen supply to combustion.
