Please follow these safety instructions closely to prevent accidents and mate-
rial losses.
Safety instructions explained
Danger
This symbol warns against the
risk of injury.
!Please note
This symbol warns against the
risk of material losses and envi-
ronmental pollution.
Note
Details identified by the word "Note" con-
tain additional information.
Target group
These instructions are exclusively inten-
ded for qualified contractors.
■ Work on electrical equipment must
only be carried out by a qualified elec-
trician.
■ The system must be commissioned by
the system installer or a qualified per-
son authorised by the installer.
Regulations
Observe the following when working on
this system:
■ National installation regulations
■ Statutory regulations regarding the
prevention of accidents
■ Statutory regulations regarding envi-
ronmental protection
■ The Code of Practice of relevant trade
associations
■ All current safety regulations as
defined by DIN, EN, DVGW, VDE and
all locally applicable standards
aÖNORM, EN and ÖVE
cSEV, SUVA, SVTI and SWKI
If you smell flue gas
Danger
Flue gas can lead to life threat-
ening poisoning.
■ Shut down the heating system.
■ Ventilate the installation site.
■ Close all doors in the living
space.
Flue systems and combustion air
Ensure that flue systems are clear and
cannot be sealed, for instance due to
accumulation of condensate or other
causes. Ensure a sufficient supply of
combustion air.
Instruct system users that subsequent
modifications to the building characteris-
tics are not permissible (e.g. cable/pipe-
work routing, cladding or partitions).

Danger
Leaking or blocked flue systems,
or an insufficient supply of com-
bustion air can cause life threat-
ening poisoning from carbon
monoxide in the flue gas.
Ensure the flue system is in
proper working order. Apertures
for supplying combustion air
must be non-closable.
Extractors
Operating appliances that extract air to
the outside (cooker hoods, extractors, air
conditioning units, etc.) can create neg-
ative pressure. If the boiler is operated at
the same time, this can lead to reverse
flow of the flue gas.
Danger
The simultaneous operation of
the boiler and appliances that
extract air to the outside can
result in life threatening poison-
ing due to reverse flow of the flue
gas.
Fit an interlock circuit or take suit-
able steps to ensure a sufficient
supply of combustion air.
Working on the system
■ Isolate the system from the power sup-
ply (e.g. by removing the separate fuse
or by means of a mains isolator) and
check that it is no longer 'live'.
■ Safeguard the system against recon-
nection.
Danger
Hot surfaces can cause burns.
■ Before maintenance or service
work, switch OFF the appli-
ance and let it cool down.
■ Never touch hot surfaces on
the boiler, burner, flue system
or pipework.
!Please note
Electronic assemblies can be
damaged by electrostatic dis-
charge.
Before beginning work, touch
earthed objects, such as heating
or water pipes, to discharge static
loads.
Repair work
!Please note
Repairing components that fulfil a
safety function can compromise
the safe operation of the sys-
tem.
Faulty components must be
replaced with original Viessmann
spare parts.

Auxiliary components, spare and
wearing parts
!Please note
Spare and wearing parts that
have not been tested together
with the system can compromise
its function. Installing non-author-
ised components and making
non-approved modifications or
conversions can compromise
safety and may invalidate the
warranty.
For replacements, use only orig-
inal spare parts supplied or
approved by Viessmann.

The appliance is only intended to be
installed and operated in sealed unven-
ted systems that comply with EN 12828 /
DIN 1988, or solar thermal systems that
comply with EN 12977, with due atten-
tion paid to the associated installation,
service and operating instructions. DHW
cylinders are only designed to store and
heat water of potable water quality. Heat-
ing water buffer cylinders are only
designed to hold fill water of potable
water quality. Only operate solar collec-
tors with the heat transfer medium
approved by the manufacturer.
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 pur-
pose other than heating the building or
DHW shall be deemed inappropriate.
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.
Incorrect usage also occurs if the com-
ponents in the system are modified from
their intended use (e.g. through direct
DHW heating in the collector).
Adhere to statutory regulations, espe-
cially concerning the hygiene of potable
water.

Siting information
!Please note
To prevent material losses, install
the heating water buffer cylinder
in a room free from the risk of frost
and draughts.
Otherwise the heating water buf-
fer cylinder must be drained
when not in use and there is a risk
of frost.
■ Provide adequate clearance from the
wall so that the temperature controller
can be operated (if installed).
■ Placing the heating water buffer cylin-
der on a plinth will make the room eas-
ier to clean.
