Please follow these safety instructions closely to
prevent accidents and material 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 environmental pollution.
Note
Details identified by the word "Note" contain additional
information.
Target group
These instructions are exclusively intended for quali-
fied contractors.
■Work on electrical equipment must only be carried
out by a qualified electrician.
■The system must be commissioned by the system
installer or a qualified person 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 environmental pro-
tection
■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 threatening 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 conden-
sate or other causes. Ensure a sufficient supply of
combustion air.
Instruct system users that subsequent modifications to
the building characteristics are not permissible (e.g.
cable/pipework routing, cladding or partitions).
Danger
Leaking or blocked flue systems, or an insuffi-
cient supply of combustion air can cause life
threatening 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 negative 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 poisoning due to
reverse flow of the flue gas.
Fit an interlock circuit or take suitable steps to
ensure a sufficient supply of combustion air.
Working on the system
■Isolate the system from the power supply (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 reconnection.
Danger
Hot surfaces can cause burns.
■Before maintenance or service work, switch
OFF the appliance 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 elec-
trostatic discharge.
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 func-
tion can compromise the safe operation of the
system.
Faulty components must be replaced with origi-
nal Viessmann spare parts.

Auxiliary components, spare and wearing parts
!Please note
Spare and wearing parts that have not been tes-
ted together with the system can compromise its
function. Installing non-authorised components
and making non-approved modifications or con-
versions can compromise safety and may inva-
lidate the warranty.
For replacements, use only original spare parts
supplied or approved by Viessmann.

The appliance is only intended to be installed and
operated in sealed unvented systems that comply with
EN 12828 / DIN 1988, or solar thermal systems that
comply with EN 12977, with due attention paid to the
associated installation, service and operating instruc-
tions. DHW cylinders are only designed to store and
heat water of potable water quality. Heating water buf-
fer cylinders are only designed to hold fill water of pot-
able water quality. Only operate solar collectors with
the heat transfer medium approved by the manufac-
turer.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for a purpose other
than heating the building or DHW shall be deemed
inappropriate.
Any usage beyond this must be approved by the man-
ufacturer for the individual case.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and results in an exclusion of liability.
Incorrect usage also occurs if the components in the
system are modified from their intended use (e.g.
through direct DHW heating in the collector).
Adhere to statutory regulations, especially concerning
the hygiene of potable water.

!Please note
To prevent material damage, site the buffer cyl-
inder in a draught-free room free from the risk of
frost.
When not in use, the buffer cylinder must be
drained if 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 cylinder on a plinth
will make the room easier to clean.
■Use the adjustable feet to level the buffer cylinder.
Note
Never extend the adjustable feet beyond a total length
of 35 mm.
