For details refer to Vitodens 100-W or Vitodens 200-W Installation Instructions (as may be applicable).
For coaxial venting systems only:
In the event of flue gas leakage, the
boiler enclosure provides a tightly
sealed system on the inside of the
building. Escaping flue gas is fed back
into the combustion air intake,
preventing any flue gas from entering
the living area.
The venting system may be concealed
in a chase.
Minimum and maximum wall thickness
through which the horizontal vent-air
intake termination may be installed:
Minimum:
1”(25.4 mm)
Maximum:
19.6”(497.8 mm)
Vent-air intake system must be
properly installed and sealed.
CAUTION
Under certain climatic conditions some building materials may be affected by flue products expelled in close proximity to
unprotected surfaces. Sealing or shielding of the exposed surfaces with a corrosion resistant material (e.g. aluminum
sheeting) may be required to prevent staining or deterioration. The protective material should be attached and sealed (if
necessary) to the building before attaching the vent termination. It is strongly recommended to install the vent termination
on the leeward side of the building.

The Vitodens 100-W and 200-W
boilers are NOT approved for
common-venting applications.
Do not attempt to common-vent the
Vitodens 200-W boiler with any
other appliance.
WARNING
Failure to ensure that all flue gases
have been safely vented to the
outdoors can cause property
damage, severe personal injury, or
loss of life. Flue gases may contain
deadly carbon monoxide.
