2.3. OPERATING AREA
For proper functioning and a good temperature distribution, the stove
should be positioned in a location where it is able to take in the air
necessary for combustion of the pellets (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
proximity to the stove) 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
them 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 stove 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 stove in a room with an explosive
atmosphere is prohibited.
The floor of the room where the stove is to be
installed must be strong enough to take its weight.
If walls are flammable, maintain a minimum distance of 10cm at the
rear (A), 10cm 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 stove should be considerably increased.
If the flooring is made of wood, provide a floor
protection surface in compliance with current
national standards.
2.4. 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 stove 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 stove, a hole must be
made with a minimum free cross-section of 100 cm². (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:
communicate directly with the room where the stove is installed
be protected by a grille, metal mesh or suitable guard, as long as
this does not reduce the area below the minimum.
