Combined air supply and flue gas outlet system
(CLV) with overpressure
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.
