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 m
3
/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 30 m
3
. The
air must come in through permanent openings made in
walls (in prossimity to the
boiler
) which give onto the
outside, with a minimum cross-section area of 100 cm
2
.
These openings must be made in such a way that it is not
possible for then to be obstructed in any way.
Alternatively, the air can be taken from rooms adjacent to
the one which needs ventilating, as long as they are
provided with an air intake from the outside, and are not
used as bedrooms or bathrooms, and provided there is
no fire risk such as there is for example in garages,
woodsheds, and storerooms, with particular reference
to what is laid down in current standards.
It is not permissible to install the
boiler
in bedrooms, bathrooms, or
in a room where another heating
appliance is installed (fireplace,
boiler
etc.)
which does not have its own independent air
intake. Locating the
boiler
in a room with
an explosive atmosphere is prohibited.
The floor of the room where the
boiler
is to be
installed must be strong enough to take its
weight. If walls are flammable, maintain a minimum
distance of 10 cm at the rear (A), di 40 cm at the
side (B) and 150 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
boiler
should be considerably increased.
Connection to the external air intake
It is essential that at least as much air must be able to
flow into the room where the
boiler
is installed as is
required for proper combustion in the appliance and for
the ventilation of the room.
This can be effected by means of permanent openings in
the walls of the room to be ventilated, which give onto the
outside, or by single or collective ventilation ducts.
For this purpose, on the external wall near the
boiler
, a hole
must be made with a minimum free cross-section of 100
cm
2
. (equivalent to a round hole of 12 cm diameter or a
square hole 10x10 cm) protected by a grille on the inside
and the outside.
The air intake must also: communicante directly with
the room where the
boiler
is installed be protected by a
grille, metal mesh or suitable guard, as long as this does
not reduce the area below the minimum.
Be positioned in such a way as to be impossible to
obstruct.
It is not compulsory to connect the air
intake directly with the
boiler
(so that
it draws air directly from outside), but it
is
essential at all events to ensure an airflow of 50
cubic metres per hour by the use of a hole of the
dimensions given. See standard UNI 10683.
In the presence of wood floors, install a
floor protection surface in compliance
with the rules in force in the country
