Vitodens 200-W B2HA 80 to 100, 285 to 352 Installation
When designing a multiple Vitodens system as shown
above, please reference applicable multiple Vitodens
technical documentation, and contact your local Viessmann
Sales Representative for further assistance.
This installation example depicts a possible piping layout
for multiple Vitodens 200-W, B2HA boilers equipped with
Viessmann System Technology. Please note that this
example is based on a simplified conceptual drawing only!
Piping and necessary componentry must be field verified.
A low water cut-off (LWCO) must be installed where
required by local codes.
Proper installation and functionality in the field is the
responsibility of the heating contractor.
WARNING
If a DHW storage tank other than a Viessmann
Vitocell 100 or 300 tank is used, the installer must
verify proper operation of the Viessmann DHW tank
temperature sensor with the original manufacturer
of the tank. Viessmann strongly recommends the
installation of a temperature tempering valve in the
DHW supply line.
