Venting Requirements

Venting option #2 (Category III)

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 on 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.

hole on the side of the vent pipe approximately two
to three times the vent pipe diameter away from the
flue gas collar of the boiler.
3. Seal and insulate the vent pipe.
