2 x 87° balanced flue bends are taken into consideration for the
maximum flue lengths.
2.5 Plastic (PPs) balanced flue system for external wall connection (type C
1749)
As part of the CE approval test it was verified that surface tempera-
tures on the Vitodens and its balanced flue system do not exceed
85 °C at any point.
Observe the design information to CEN/TR 1749, in particular
the arrangement/position of the wall terminal.
Install the connection line with a fall of at least 3° to the boiler.
Install an inspection port in the flue for checking and cleaning the
flue pipe.
The flue for external wall connection has been certified as a concen-
tric balanced flue system with the Vitodens condensing boiler.
A performance verification to EN 13384 is not required.
