2.4 Plastic (PPs) balanced flue system for routing over external walls (type C
2008)
The Vitodens may also be connected, without a shaft, to a flue pipe
routed over an external wall.
The combustion air is drawn in via the air inlet piece. The vertical
external pipe acts as protection and the static air inside acts as thermal
insulation.
