Frost Protection; Intended Use - Viessmann Vitodens 100 Series Installation And Service Instructions Manual

Frost protection

!
Please note
Frost protection is only guaran-
teed with a reliable power sup-
ply, gas supply and sufficient
heating water content.

Intended use

The appliance is only intended to be
installed and operated in sealed unven-
ted heating systems that comply with
EN 12828 and CECS 215, with due
attention paid to the associated installa-
tion, service and operating instructions.
It is only designed for heating up heat-
ing water that is of potable water qual-
ity.
Intended use presupposes that a fixed
installation in conjunction with permissi-
ble, system-specific components has
been carried out.
Commercial or industrial usage for a
purpose other than heating the building
or DHW shall be deemed inappropriate.
Following installation or repairs,
switch ON the power supply
(MCB/fuse, mains isolator) and
the control unit ON/OFF switch.
Open the gas shut-off valve to
ensure frost protection.
Any usage beyond this must be
approved by the manufacturer 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 lia-
bility. 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).
