The appliance is only intended to be
installed and operated in sealed unven-
ted heating systems that comply with
EN 12828, with due attention paid to the
associated installation, service and
operating instructions. It is only designed
for the heating of water that is of potable
water quality.
Intended usage presupposes that a fixed
installation in conjunction with permissi-
ble, system-specific components has
been carried out.
Commercial or industrial usage for a pur-
pose other than heating the building or
DHW does not comply with regulations.
Any usage beyond this must be
approved by the manufacturer for the
individual case.
Incorrect usage or operation of the appli-
ance (e.g. the appliance being opened
by the system user) is prohibited and
results in an exclusion of liability. Incor-
rect usage also occurs if the components
in the heating system are modified from
their intended function (e.g. if the flue
gas and ventilation air paths are
sealed).
Commissioning
The commissioning and matching of the
control unit to local conditions and build-
ing characteristics, as well as instructing
the user in the operation of the system,
must be carried out by your heating con-
tractor.
As the user of new combustion equip-
ment, you may be obliged to notify your
local flue gas inspector of the installation
[check local regulations]. Your local flue
gas inspector will also inform you [where
appropriate] about work he may be
required to carry out on your combustion
equipment (e.g. regular checks, clean-
ing).
Terminology

ing of the functions of your Vitotronic
