6.2 COMBUSTION AIR
During operation the stove takes in a certain amount
of air from the room where it's installed; this air must
be replaced through an opening to the outside from
the room (Fig. 6.2 - PA = Fresh air vent).
It's possible to connect the rear combustion air pipe
of the machine, pipe diameter 60 mm, max. length
4 m. for external connection (Fig. 6.2.1)
If the wall behind of the stove is an outside wall,
make an opening for drawing in combustion air
around 20-30 cm above the floor, observing the
dimensions shown on the product data sheet at
the end of this booklet.
A permanent non-closable vent cover must be
placed on the outside of the opening; in especially
windy areas or places exposed to bad weather,
install rain and wind protection elements.
Make sure that the air vent is located in such a way
that it can't be accidentally obstructed.
If it's not possible to make a fresh air opening in
the wall behind the stove (not a perimeter wall),
an opening must be made on the wall in the room
where the stove is installed that faces the outside.
If no fresh air opening can be made in the room, it
can be made in an adjacent room as long as the
two rooms are connected by a ventilation grill (Fig.
6.2.2 - C = Shutter box, G = Grill, S = Shutters)
Standard UNI 10683 prohibits combustion air being
drawn in from garages, combustible material stores
or places where there is a fire risk.
If there are other heating appliances in the same
room, the fresh air vents must guarantee the
required volume of air for correct operation of all
the appliances.
If one or more exhaust fans (range hoods) are
installed and operating in the room where the stove
is located, combustion problems may occur due to
a lack of combustion air
