6.4 Combustion air
The appliance, during its operation, requires
combustion air.
The inflow of combustion air can be obtained in
the following ways:
• it can come directly from outside with direct
connection to the combustion chamber (
Fig.
18
-
Fig. 21
).
• it can come from the installation room or suita-
ble adjacent rooms ( Fig. 22 - Fig. 23 )
Extraction of combustion air from outside
In this case, a possible alternative may be:
• to channel the combustion air using a coaxial
pipe to expel the flue gases and extract the air
( Fig. 18 - Fig. 19 - A, B = Air inlet, C, D = Flue gas
outlet); in this case it is not necessary to create
a classic air intake in the room.
• to connect the combustion air inlet of the ap-
pliance to the air intake using a special pipe
( Fig. 20 - Fig. 21 ).
