Operating area
For proper functioning and a good temperature
distribution, the boiler shoul be positioned in a
location where it is able to take in the air necessary
for combustion of the pellet (about 40 m³/h
must be available), as laid down in the standard
governing the installation and in accordance with
local national standards. The volume of the room
must not be less than 15 m³. It is compulsory to
install an adequate outdoor air intake which would
allow oxidising air input necessary for correct
operation of the product. The air flow between
the outside and the installation premises can take
place directly, through an opening on an external
wall of the premises (preferred solution, see Figure
1a); or indirectly, through air intake from the
adjoining premises with air intake and permanently
communicating with the installation premises (see
Figure 1b). Adjoining premises excludes those used
as bedrooms, bathrooms, garages, common areas
of a building and, in general, premises in danger
of catching fire. Consider the doors and windows
present which could interfere with correct air flow
to the boiler and maintain 1.5 metres from any
smoke outlet. The air intake must have a minimum
total net surface of 150 cm
external grate which must not be obstructed and/or
blocked and which should be periodically cleaned:
the aforementioned surface should be increased as
a result if there are other active generators inside
the premises (for example: electric fans for stale air
extraction, kitchen hood, other stoves, etc...), which
could generate a negative pressure environment. A
check is necessary, with all the equipment on, that
the drop in pressure between the room and the
outdoors does not exceed a value of 4 Pa.
The section must be calculated as follows:

FIGURA A- DIRETTAMENTE DALL'ESTERNO
FIGURE 1a- DIRECTLY FROM OUTSIDE
You can connect the air necessary for combustion
directly to the external air intake, with a tube of at
least 50mm, with a maximum length of 2 linear
metres; each curve of the tube is equal to a loss of
one linear metre.

It is not permissible to install
the thermostove in bedrooms,
bathrooms, or in a room where
another heating appliance is installed
(fireplace, stove etc.) which does not have
its own independent air intake.
Locating the thermostove in a room with
an explosive atmosphere is prohibited.
The
floor
of
the
thermostove is to be installed must be
strong enough to take its weight. If walls
are
flammable,
maintain
distance of 20 cm at the rear (A), of 40 cm
at the side (B) and 100 cm at the front.
If the room contains objects which are
believed to be particularly delicate, such
as drapes, sofas and other furniture, their
distance from the thermostove should be
considerably increased.
In the presence of wood floors,
install a floor protection surface in
