!
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 designed for qualified personnel.
■ Work on gas appliances must only be carried out by a qualified gas fitter.
■ Work on electrical equipment must only be carried out by a qualified electrician.
Regulations
Observe the following when working on this system
■ all legal instructions regarding the prevention of accidents,
■ all legal instructions regarding environmental protection,
■ the Code of Practice of relevant trade associations,
■ all current safety regulations as defined by DIN, EN, DVGW, TRGI,
TRF, VDE and all locally applicable standards.
Working on the system
■ Isolate the system from the power supply and check that it is no longer 'live', e.g. by removing a separate fuse or by means of a mains isolator.
■ Safeguard the system against unauthorised reconnection.
■ When using gas as fuel, also close the main gas shut
-off valve and safeguard against unauthorised reopening.

Product information
Vitodens 200-W, WB2C
Set up for operation with natural gas E and LL.
For conversion to LPG P (without conversion kit), see the service instructions.
Conversion for other target countries
The Vitodens 200-W should generally only be delivered to those countries specified on the type plate. For deliveries to alternative countries, an approved contractor, on his own initiative, must arrange individual approval in accordance with the law of the land.
Multi-boiler system
In connection with the installation of a multi-boiler system observe the installation instructions of the multi-boiler system accessories.
For installations in a multi-boiler system, generally the boiler coding card needs to be
replaced (see page 16).

Note
This boiler (protection IP X4 D) is approved for installation in wet rooms inside protection area 1 according to
DIN VDE 0100 [Germany], if hosed water can be prevented.
Observe the requirements of
DIN VDE 0100 [or local regulations].
1. Prepare the water connections. Flush the heating system thoroughly.
2. Prepare the gas connection according to TRGI or TRF [or local regulations].
3. Prepare the electrical connections.

2. Carry out a tightness test.
Note
For the tightness test, use only suitable and approved leak detecting agents (EN 14291) and devices.
Leak detecting agents with unsuitable constituents (e.g. nitrites, sulphides) can lead to material damage.
Remove residues of the leak detecting agent after testing.
!
Please note
Excessive test pressure may damage the boiler and the gas valve.
Max. test pressure 150 mbar.
Where higher pressure is required for tightness tests, separate the boiler and the gas valves from the gas supply pipe (undo the fitting).
3. Vent the gas line.

Danger
Incorrect core termination can cause severe injuries and damage to the equipment.
Take care not to interchange wires "L1" and "N".
■ Install an isolator in the power supply line that simultaneously isolates all non-earthed conductors from the mains with at least
3 mm contact separation.
We additionally recommend installing an AC/DC-sensitive
RCD (RCD class B ) for
DC (fault) currents that can occur with energy-efficient equipment.
■ Max. fuse rating 16 A.
lH ■ Power supply accessories (230 V/
50 Hz). Where the boiler is installed in a wet area, the connection of accessories to the power supply must not be carried out at the control unit. The power supply connection for accessories can be made immediately at the control unit, if the boiler is installed outside wet areas. This connection is directly controlled with the system
ON/OFF switch (max. 3 A).

Replacing the boiler coding card for installation in a multi-boiler system
If this boiler is installed in a multi-boiler system, always replace the fitted boiler coding card with the equivalent card for multi-boiler systems.
The boiler coding card for multi-boiler systems is secured at the cover panel behind the control unit.
Corresponding installation instructions are supplied with the boiler coding card.
