Vitorond 200, VD2A Series Installation
Venting Connections

Venting (option #2)

The Vitorond 200 boiler is a Category III positive pressure
non-condensing boiler.
Each boiler must be vented individually.
The vent system must be properly designed and suitable
materials must be selected. The chimney must be gas
tight.
Use an AL29-4C® special stainless steel venting system
(UL/ULC listed for Category III) for single-wall vertical
venting of the Vitorond 200 boiler.
For more details on the positive pressure venting option,
see the Viessmann installation instructions for the positive
pressure venting system.
IMPORTANT
The flue size outlet of the boiler does not automatically
determine the horizontal breeching, or the actual chimney
diameter. The chimney size must be designed for the
actual boiler model and its respective input.
Please refer to the Positive Pressure Venting
System Installation Instructions.
