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

There is an option of routing several flues in balanced flue mode
through a common, sufficiently sized shaft. For this, the Vitodens con-
densing boilers must be installed in the same living space. For reasons
of fire protection, the installation and connection on different levels or
in different rooms is not possible. The flues and the shaft covers must
be professionally supported inside/on the shaft. For balanced flue
components from the Vitodens to the common shaft, see page 13.

Layout examples

Minimum clearances of the individual flues to DIN V 18160-1:
■ In square/rectangular shafts: 20 mm
■ In round shafts: 30 mm
