T
his installation example depicts a possible piping layout
for multiple Vitodens 200-W, B2HB 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.
