EXTERNAL COMBUSTION AIR INTAKE (A)
To restore the oxygen burnt during operation, it is
necessary to have an adequate air intake, pursuant to
local regulations, of 200 cm
In accordance with local regulations, the air intake can
be mounted outside or in suitable rooms not subject
to depression.
The cladding must have the grille at floor level so that
combustion air can enter the product.

DIRECT AIR INTAKE
DIRECT AIR INTAKE
Install an air intake with an effective size (net of the
mesh or other protective equipment) that is at least
equal to that of the air intake at the back of the product.
Choose the diameter based on the load losses.
Connect the air intake to the appliance's air intake with
a pipe that may also be flexible. Increase the diameter
of the pipe if the pipe is not smooth: assess any load
loss.
A maximum length of 5 metres is recommended, with
no more than 3 bends depending on the draft of the
flue.
The air maybe drawn from an adjacent room only if:
• the flow is taken from permanent, unobstructed
openings communicating with the outdoors
• the air pressure in the adjacent room is never
reduced to a level below outdoor pressure
• the adjacent room is not a garage, subject to fire
hazard, a bathroom or a bedroom
• the adjacent room is not a shared room in the
condominium.
In Italy, UNI 10683 provides that ventilation is sufficient
even if a pressure difference between the outdoors
and indoors of no more than 4 PA is guaranteed (UNI
EN 13384-1). The installer who issues the declaration
of conformity is responsible for ensuring these
conditions.
