Plastic (Pps) Balanced Flue System For External Wall Connection; 13X To Trgi 2008); Max. Total Length Of The Flue Pipe - Viessmann VITODENS Technical Manual

Design and sizing information for connection on the flue gas side
Subtract additional bends, tees and straight lengths from the maximum
length using the following values:
■ Balanced flue bends 45°: 0.5 m
■ Balanced flue bends 87°: 1 m
■ Balanced flue inspection tee: 1.5 m
2.4 Plastic (PPs) balanced flue system for external wall connection (type C
As part of the CE approval test it was verified that no surface temper-
atures on the Vitodens or its balanced flue system will exceed 85 °C.
Observe the implementation information to TRGI 2008, in partic-
