Viessmann vitodens Technical Manual page 117

Plastic (PPs) balanced flue system (BF) for routing over external walls
(type C according to TRGI '86/96)
53x
Vitodens may also be connected, without
duct, to a flue pipe on an external wall.
The combustion air is drawn in via the air
inlet piece. The vertical external pipe acts
as protective pipe and as thermal
insulation due to its static air layer.

Depending on the length of pipe
protruding above the roof, various
∅ 60 mm
routing options are available.
∅ 100 mm
The outside wall pipe has been tested and
∅ 80 mm CE-designated as a concentric balanced
∅ 125 mm flue system and as one technical unit with
the Vitodens condensing boiler.
∅ 100 mm
A function verification according to
∅ 150 mm
EN 13384 is not required.

When using a balanced flue roof terminal system size 100, fit a
balanced flue sliding coupling to reverse the joining direction
of the external pipe.
