Viessmann Vitopend 100-W Installation And Service Instructions For Contractors page 7

Preparing for installation
Vitopend 100-W, type WH1D
Set up for operation with natural gas E.
May be converted to alternative gas
types with a conversion kit.
Intended use
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.
Preparing for installation
The Vitopend 100-W must only be deliv-
ered to the countries specified on the
type plate. For deliveries to alternative
countries, approved contractors must
arrange individual approval on their own
initiative and in accordance with the law
of the land.
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).
