• 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
appliances or in the presence of hood exhausts.
It is forbidden to use direct wall discharge or
towards closed spaces or any other form of
discharge not planned by legislation in force in the
country of installation (In Italy, only roof discharge
is permitted)
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)
.
3.4 CHIMNEY STACK
The standard UNI 10683 states the stack must meet
the following features:
• 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.
3.5 HERMETIC PRODUCT
In the event of installation of a hermetic product,
you can execute one of the following types of
connection 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.
