7.5 Collective ue gas outlet
Optingforacollectiveuegasoutletisdeterminedby:
- The position of the boilers with regard to their outlet area
- Su󰀩cientspaceabovetheboilers
- Large number of boilers
You may opt for:
- Collectiveuegasoutletunder-pressure
- Collectiveuegasoutletover-pressure
Inmany situations, ue gases cannotbe vented individuallybecause the installation
is indoors. For such situations, we recommend collective venting by means of under-
pressureorover-pressureusingauegasoutletsystem.Theairsupplymayalsobe
supplied collectively, but if the boiler room is suitable for that purpose (refer to chapter
6.3) it may also be obtained from this area (`open device` Boiler category B).
In the case of collective venting of ue gases, the ue gas-venting outlet always
has to end up in the open area (outlet area 1).
