Maintenance parts and spare parts

Maintenance parts and spare parts can be identified and ordered directly online.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and will result 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 selected gas category in the delivered condition
and the associated nominal gas pressure are given on
the boiler type plate. The type plate also shows the
other gas types and pressures with which the boiler
can be operated. A conversion within the stated natu-
ral gas groups is not required. For conversion to LPG
(without conversion kit), see "Commissioning, inspec-
tion and maintenance".
The Vitodens 111-W may only be delivered to coun-
tries listed on the type plate. For deliveries to other
countries, approved contractors must arrange individ-
ual approval on their own initiative and in accordance
with the law of the country in question.
