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.
