RADIATION AREA
Area immediately near the hearth in which the heat caused by
combustion is diused, where no combustion materials must
be present.
REFLUX AREA
Area where leaking of the combustion products is veried,
from the appliance towards the installation room.
The installation must be preceded by checking the chimneys,
ues or unload terminals positioning of appliances similarly
to:
 Installation prohibitions
 Legal distances
 Limitations disposed by local administrative regulations
or particular authority prescriptions.
 Conventional limitations deriving from condominium
regulations, constraints or contracts.
INSTALLATIONS ALLOWED
Only appliances working in a sealed manner respect to the
room or which do not place the room in depression respect to
the external environment, can exist or be installed in the room
where the heat generator will be installed.
Appliances for cooking food and relative hoods without
extractor are only allowed in kitchens.
INSTALLATIONS NOT ALLOWED
In the room where the heat generator will be installed the
following must not pre-exist or be installed:
 hoods with extractor
 collective type ventilation pipes.
Should these appliances be in rooms adjacent, communicating
with the installation room, the simultaneous use of the heat
generator is forbidden, where a risk exists of one of the two
rooms being placed in depression respect to the other.
CONNECTION TO THE SMOKE EVACUATION SYSTEM
UNI 10683 (2005) Standard
SMOKE CHANNEL OR FITTINGS
To mount the smoke channels, non-ammable elements will
have to be used, ideal for resisting combustion products and
their eventual condensing.
The use of exible metal and asbestos cement pipes to
connect the appliances to the ue is forbidden, even for pre-
existing smoke channels.
There must be continuity between the smoke channel and the
ue so that the ue does not lean on the generator. The smoke
channels must not cross rooms where the installation of the
combustion appliances is not allowed.
The mounting of the smoke channels must be carried out in
order to guarantee smoke seal for the appliance functioning
conditions, limit the forming of condensate and avoid it being
transported towards the appliance.
The mounting of horizontal routes must be avoided.
For appliances where ceiling or wall non-coaxial discharges
with respect to the appliance combustion product outlet
have to be reached, the direction changes will have to realised
using open bends not greater than 45° (see gures below).
For the heat generator appliances equipped with electric fan
for expelling combustion products, the instructions below
must be followed:
45°
<
45°
<
 The horizontal routes will have to have a minimum
upward slope of 3%
 The length of the horizontal route must be minimal and,
however, not longer than 3 metres
 The number of direction changes including the one for
eect of using the "T" element must not be more than 4.
In any case, the smoke channels must seal the combustion and
condensate products and be insulated if they pass outside the
installation room.
The use of counterslope elements is forbidden.
The smoke channel must allow the recovery of soot or be
brushable.
The smoke channel must have constant section. Any section
changes are only allowed at the ue coupling.
It is forbidden to have other air supply channels and pipes for
system engineering, especially if over-sized, transit inside the
smoke channels. The mounting of manual draught adjustment
devices on forced draught appliances is forbidden.
