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 gas installations must only be carried out by
a registered gas fitter.
■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:
■Statutory regulations regarding the prevention of
accidents
■Statutory regulations regarding environmental pro-
tection
■Codes of practice of the relevant trade associations
■All current safety regulations as defined by DIN, EN,
DVGW, TRGI, TRF, VDE and all locally applicable
standards
■Gas Safety (Installation & Use) Regulations
– the appropriate Building Regulation either the
Building regulations, the Building Regulation (Scot-
land), Building Regulations (Northern Ireland),
– the Water Fittings Regulation or Water Bylaws in
Scotland,
– the current I.E.E. Wiring Regulations.
If you smell gas
Danger
Escaping gas can lead to explosions which may
result in serious injury.
■Do not smoke. Prevent naked flames and
sparks. Do not switch lights or electrical appli-
ances on or off.
■Close the gas shut-off valve.
■Open windows and doors.
■Evacuate any people from the danger zone.
■Notify your gas or electricity supply utility from
outside the building.
■Shut off the electricity supply to the building
from a safe place (outside the building).
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
Life-threatening poisoning caused by carbon
monoxide in the flue gas occurs as a result of
leaking or blocked flue systems or an insufficient
supply of combustion air.
Ensure the flue system is in proper working
order. It must not be possible to close apertures
for interconnected combustion air supply.
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
■Where gas is used as the fuel, close the main gas
shut-off valve and safeguard it against unintentional
reopening.
■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.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing any work, touch earthed
objects, such as heating or water pipes to dis-
charge static loads.
Repair work
!Please note
Repairing components that fulfil a safety func-
tion can compromise the safe operation of your
system.
Defective components must be replaced with
genuine 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 our 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 heating systems that
comply with EN 12828, with due attention paid to the
associated installation, service and operating instruc-
tions. 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 permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for a purpose other
than heating the building or DHW does not comply with
regulations.
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 heating
system are modified from their intended function (e.g.
if the flue gas and ventilation air paths are sealed).
Product information

LL.
For conversion to LPG P (without conversion kit), see
the service instructions.
In principle the Vitodens 200-W may only be delivered
to countries listed on the type plate. For deliveries to
alternative countries, an approved contractor must
arrange individual approval on his own initiative and in
accordance with the law of the country in question.
