It is mandatory to have an appropriate air intake connected to the outside to bring to the stove the air
required for combustion.
•
The air inflow from outside to the inner occurs directly, through an opening on the external wall of the room
).
•
Bedrooms, garages, and store of flammable materials are excluded.
•
The air inlet should have a total net surface of 80 sqcm
2
: the aforesaid surface is to widen if inside the room
there are other activated appliances (for example: electric ventilators for foul air suction, cooker hoods, other
stoves, etc...) which depress the environment.
•
At switched on appliance it is necessary to check that the pressure fall between the room and the outside
does not exceed 4,0 Pa value: if necessary widen the air inlet.
•
The air inlet must be realized at a height close to the floor with an external grid against birds. In such a way it
cannot be obstructed by any object.

Curve inlet to turn downwards
For products with a rated power of less than 6 kW it is not advisable to draw the combustion air from outside
through direct connection as this can cause combustion difficulties.
For all other NON SEALED products we recommend that you connect through a pipe with a minimum diameter
of 50 mm and a maximum length of 1 m.
With this solution the external air intake vent (see
) can be reduced from 80 cm
2
to 67 cm
2
.
•
Assembly of a concentric smoke extraction pipe is prohibited.
•
During installation you must verify the minimum distances for the combustion air intake (see
•
On the outside wall it is necessary to install a 90° bend to protect the flow of combustion air by wind effects:
turn the beginning of the curve downward (see
).
With this type of solution, if the burning is not optimal (scarcely oxygenated flame, glass that gets dirty quickly,
etc.) you may need to change the combustion parameters of the stove (consult an Authorized Technician) or
review the length and the type of connection made.
Check with local authorities if there are restrictive regulations regarding combustion air
intake: if present, they must be applied.
