Air should enter through permanent apertures made in the walls (near
the stove) that lead to the outside. These should have a minimum
cross-section of 100 cm
2
.
These apertures must be made so as not to be obstructed in any way.
Air may also be taken from rooms adjoining the one to be ventilated,
provided they are equipped with an external air inlet and are not used
as bedrooms or bathrooms. These must not be rooms that present a
fire hazard, for example: garages, timber storerooms, warehouses for
flammable materials. The provisions of all the applicable standards in
force must be observed in all circumstances.
Installation of the stove is not permitted in
bedrooms, bathrooms or in any room in which
another heating appliance is installed without
an independent air inflow (fireplace, stove
etc.).
It is forbidden to position the stove in rooms
with an explosive atmosphere.
The floor of the room in which the stove is
installed must be suitably sized to withstand
the weight of the stove.
If the ventilation is not ducted, maintain a minimum distance of 20 cm
at the back (
A
) and sides of the stove (
B
). If ventilation is ducted,
maintain a distance of 2 cm at the back of the stove (
C
) and a distance
of 20 cm at the sides of the stove (
D
).
The room ventilation can be adjusted
towards the rear wall only if there is
suitable caulked ducting of the hot air
flow.
If particularly delicate objects are present, such as furniture, curtains or
sofas, increase the stove clearances substantially.
If the floor is wooden lay down a floor guard in
compliance with the applicable standards in force in
the country of installation.
2.4.
CONNECTING THE EXTERNAL AIR INLET
The room in which the stove is installed MUST provide at least as much
airflow as is required for regular combustion of the appliance in the
room. This can be achieved via permanent apertures made in the walls
of the room to be ventilated, leading to the outside, or via individual or
grouped ventilation ducts.
To achieve this a through hole with a minimum free cross-section of
150 cm² must be drilled in the external wall near the stove. (12 cm
diameter or 10x10 cm square hole), protected by a grille on the inside
and on the outside.
The air inlet should also:
be directly connected to the installation setting
be protected with a grille, metal mesh or suitable protection,
provided it does not reduce the minimum cross-section.
be positioned in such a way that it cannot become obstructed
Air ventilation without ducting.
Air ventilation with ducting.
