2.8 Plastic (PPs) balanced flue system for routing multiple pipes through a shaft

It is possible to route several flues for balanced flue operation through
a common, sufficiently sized shaft. For this, the Vitodens condensing
boilers must be installed in the same living space. For reasons of fire
protection, they cannot be installed and connected on different levels
or in different rooms. The flue supports inside the shaft and the shaft
cover must be correctly implemented on site. For balanced flue com-
ponents from the Vitodens to the common shaft, see page 14.
