Product information
Vitovalor 300-P, type C3TB
Preset for operation with natural gas E, adjustable to
natural gas LL
Note on positioning
When the Vitovalor 300-P is installed close to the
coast, it should be positioned such that the flue gas
and ventilation air apertures do not come into direct
contact with saline air, in order to prevent damage due
to corrosion.
Minimum temperature inside the installation room
+3 °C
Vitovalor 300-P in systems with photovoltaic and
solar thermal equipment
Operating the Vitovalor 300-P in conjunction with a
photovoltaic or solar thermal system is not recommen-
ded. An integral PV system would falsify the statistical
data of the energy manager as it is not designed for
such a combination. Vitovalor 300-P runtimes could be
reduced and economically efficient operation would no
longer be guaranteed. The same applies if the
Vitovalor 300-P is operated in conjunction with a solar
thermal system or any additional heat generator. The
integral heating water buffer cylinder would be heated
additionally which would, in turn, reduce the
Vitovalor 300-P runtime. If the Vitovalor 300-P is nev-
ertheless operated in conjunction with a photovoltaic or
solar thermal system, a higher ranking energy man-
ager must be provided on site.

Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and results in an exclusion of liability. Incorrect
usage also occurs if the components in the heating
system are modified from their intended use (e.g. if the
flue gas and ventilation air paths are sealed).
The Vitovalor 300-P may in principle be supplied only
to the countries indicated on the type plate. For deliv-
eries to other countries, approved contractors must
arrange individual approval on their own initiative and
in accordance with the law of the country in question.
