Explanation of the flue systems
Category in accordance with CE
B A flue that evacuates the products of combustion to the outside
23
of the room containing the appliance. The combustion air is
drawn directly from the room.
B A flue system which is connected to a common duct system.
33
This common duct system consists of a single natural draught
flue. All pressurized parts of the appliance containing products
of combustion are completely enclosed by parts of the
appliance supplying combustion air. Combustion air is drawn
into the appliance from the room by means of a concentric
duct, which encloses the flue. The air enters through defined
orifices situated in the surface of the duct.
C Horizontal flue system. Discharge in the outside wall. Inlet
13
opening for the air supply is in the same pressure zone as the
discharge.
C Vertical flue system. Flue gas discharge via the roof. Inlet
33
opening for the air supply is in the same pressure zone as the
discharge.
C Joint air supply and flue gas discharge duct (CLV system).
43
Twin pipe or concentric.
C Separate air supply and separate flue gas discharge duct.
53
Discharge into different pressure zones.
C Free in the market available flue material with CE approval.

Discharging into different pressure zones.
C Air supply and flue gas discharge duct in shaft or ducted:
