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
Vitodens 200-W, type B2HA, B2KA
Preset for operation with natural gas E and
natural gas LL.
For conversion to LPG P (without conversion kit), see
"Commissioning, inspection, maintenance".
In principle the Vitodens 200-W may only be delivered
to countries listed 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 country in question.

Note
This boiler (IP rating: IP X4 D) is approved for installa-
tion in wet rooms inside safety zone 1 according to
DIN VDE 0100. Exposure to water jets must be pre-
vented.
Observe the requirements of DIN VDE 0100.
1. Fit the pre-plumbing jig or mounting frame provided
at the chosen installation site.
Pre-plumbing jig or mounting frame installa-
tion instructions
2. Prepare the connections on the water side for the
valves on the pre-plumbing jig or mounting frame.
Thoroughly flush the heating system.
3. Prepare the gas connection according to TRGI or
TRF [or local regulations].

4. Prepare the electrical connections. ■Power cable: NYM-J 3 x 1.5 mm2, max. fuse rat-
ing 16 A, 230 V, 50 Hz.
■Accessory cables: NYM with the required number
of cores for the external connections.
■All cables should protrude 1200 mm from the wall
near "G".

HSafety assembly
A safety assembly H to DIN 1988 and EN 806 is
required if the mains water supply pressure exceeds
10 bar (1.0 MPa), and no DHW pressure reducing
valve is installed (to DIN 4753).
Only use a non-return valve or a combined shut-off
and non-return valve in conjunction with a safety valve.
If the safety valve is used, the cold water shut-off valve
on the boiler must not be shut off.
Remove the toggle on the cold water shut-off valve (if
installed) to prevent it being shut off manually.
Shock arrestor
If draw-off points that could cause pressure peaks
(water hammer/shock) are connected to the same
pipework as the boiler (such as pressure washers,
washing machines or dishwashers), we would recom-
mend the installation of a shock arrestor near the
source of such pressure shocks.
g: Fit a small domestic expansion vessel if water
hammer occurs.
