INSTALLATION
6
appliance towards the installation room.
The installation must be preceded by checking the chimneys, ues
or unload terminals positioning regarding:
Installation prohibitions
Legal distances
Limitations disposed by local administrative regulations or
particular authority prescriptions.
Conventional limitations deriving from condominium
regulations, constraints or contracts.
INSTALLATIONS ALLOWED4.1.
Only appliances working in a sealed manner with respect to the
room or which do not place the room in depression with 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 ALLOWED4.2.
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 adjacent rooms, 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 4.3.
EVACUATION SYSTEM
UNI 10683 (2005) Standard
SMOKE CHANNEL OR FITTINGS4.3.1.
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 formation 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 respect
to the appliance smoke outlet have to be reached, the direction
changes will have to realised using open elbows not higher than
45° (see gures below).
For the heat generator appliances equipped with electric fan for
expelling fumes, the instructions below must be followed:
45°
<
gure 1

gure 2
Flue
Inspection
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 (if 4 bends
are used, use double wall piping with an internal diameter of 120
mm).
In any case, the smoke channels must seal the fuel and condensing
products and be insulated if they pass externally to 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
plant engineering, especially if over-sized, transit inside the smoke
channels. The mounting of manual draught adjustment devices on
forced draught appliances is forbidden.
