VITOCELL 100-V
Backflow preventers
Where backflow preventers are required, a
domestic water expansion tank installation
is recommended in the cold water inlet
piping before the cold water enters the
Vitocell. For the backflow device, observe
local plumbing codes and regulations.
Temperature and pressure
relief valve
A temperature and pressure relief valve
(T&P relief valve) is supplied with the tank.
The heating contractor must install the
valve on each tank in a method meeting
code requirements. If local codes require a
different relief valve, substitute the
manufacturer’s supplied valve. The tank is
approved for 150 psig. Maximum operating
pressure is 150 psig.
The T&P relief valve supplied with the tank
is tested under ANSI Z21.22 Code for Relief
Valves and Automatic Gas Shut-off Devices
for Hot Water Supply Systems.
Since the heat exchanger coil allows for
high MBH input (see Vitocell flow charts),
confirmation that the appropriate and
correct size pressure and temperature relief
valve is used and installed, is necessary.

Warranty
Our warranty for domestic hot water tanks
states that the water heated must be of
drinking (potable) water quality and that any
water treatment equipment in use must
function correctly.
Viessmann accepts no responsibility for
damage howsoever caused and reserves the
right to withdraw the product warranty if the
product has been improperly installed or
misapplied by the installer, contractor or final
user. In order to qualify for product warranty,
strict adherence to the installation and
service manuals must be assured. In the
event that Viessmann non-approved
components are utilized, Viessmann reserves
the right to withdraw all expressed or implied
warranties without written notice.
The water to be heated with the Vitocell
must be drinking (potable) water quality. If
the tank is used to heat other media, the
warranty will be null and void. Damage
resulting from excessive pressure or
temperature is clearly not the responsibility
of Viessmann.
The amount of chloride and sulfate
acceptable to the tank is limited. In areas
where high concentrations of chloride and
sulfate are present in drinking water, please
consult Viessmann for directions.
