Vitodens 100-W
Flue applications
Vitodens boilers can be installed in
virtually all domestic applications, some
examples are illustrated.
The maximum flue length is the single
biggest consideration.
Maximum flue lengths are provided and have
already allowed for 2 bends of 87° (including
support bends).
For each additional 90° elbow reduce the
maximum flue length by 1 m, each additional
45° elbow by 0.5 m.
For concentric or balanced flue systems
the max. flue length can be up to 19 m. To
match the boiler output to the flue system
length, a concentric factor has to be set - see
installation instructions.
