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).
Product information
Vitovalor PT2
Preset for operation with natural gas E, adjustable to
natural gas LL
The Vitovalor PT2 may in principle be supplied only to
the countries indicated on the type plate. For deliveries
to other countries, approved contractors must arrange
individual approval on their own initiative and in
accordance with the law of the country in question.
Note on positioning
If the Vitovalor PT2 is installed in close proximity to the
coast, the appliance should be positioned so that the
flue gas and ventilation air apertures do not come into
direct contact with saline air, in order to prevent dam-
age due to corrosion.
Do not install or operate the Vitovalor PT2 in unheated
rooms. Minimum temperature inside the installation
room +3 °C
Vitovalor PT2 in systems with photovoltaic and
solar thermal equipment
It is not possible to operate the Vitovalor PT2 in con-
junction with a solar thermal system. This would
reduce the runtimes of the Vitovalor PT2 and economi-
cally efficient operation would no longer be guaran-
teed.
If combining with a photovoltaic system, ensure that
the electricity meter is arranged correctly. An incor-
rectly arranged electricity meter would distort the stat-
istical data of the energy manager. This would reduce
the runtimes of the Vitovalor PT2 and economically
efficient operation would no longer be guaranteed.
System examples
System examples with hydraulic and electrical connec-
tion diagrams and function descriptions are available
to help setting up the heating system.
