Combined air supply and flue gas outlet system
(CLV) with overpressure.
Concentric (preferably).
Parallel (if concentric is not possible).
Minimum permitted pressure difference between
the air supply and the flue gas outlet is -200 Pa
(including -100 Pa wind pressure).
The channel must be designed for a nominal
flue gas temperature of 25°C
Place a condensation drain, equipped with a si
phon, at the bottom of the channel.
Maximum permissible recirculation of 10%.
The common outlet should be appropriate for a
pressure of at least 200 Pa.
The roof feed-through must be designed for this
configuration and must cause a draught in the
channel.
A draught diverter is not permitted.
Important
The fan speed must be adapted for
this configuration.
