vention of accidents,
■ all legal instructions regarding envi-
ronmental 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.
■ Gas Safety (Installation & Use) Reg-
ulations
– the appropriate Building Regulation

Building Regulation (Scotland),
Building Regulations (Northern Ire-
land),
– the Water Fittings Regulation or
Water Bylaws in Scotland,
– the current I.E.E. Wiring Regula-
tions.
Working on the system
■ Isolate the system from the power sup-
ply and check that it is no longer 'live',
e.g. by removing a separate fuse or by

Vitodens 200-W, WB2C
Set up for operation with natural gas H.
For conversion to LPG P (without conversion kit), see the service instructions.
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 must
on his own initiative arrange individual approval in accordance with the law of the
land.
All Vitodens 200-W WB2C up to 35kW have a built-in sealed system kit, circulating
pump and a diverter valve.
The system boilers have two pairs of heating flow / return pipes - the outer pair are
for central heating and the inner for the cylinder primaries. The hot water cylinder is
recommended to be controlled by a Viessmann cylinder temperature sensor, and if
it is an un-vented Vitocell cylinder, a 2-port valve and cylinder control stat is not
required.
The boiler is either supplied with a constant temperature controller (Vitotronic 100)
or a weather-compensated controller (Vitotronic 200).
The Vitotronic 100 (HO2A) provides a 7-day electronic timing for hot water and central
heating. A separate room thermostat may be fitted.
The Vitotronic 200 is a weather compensated controller and includes a 7-day timing
function, outdoor sensor as well as the option to control three separate heating circuits
with independent time and weather-compensated control. Additional remote control-
lers are available. A standard room thermostat can not be connected.

Preparing the boiler for installation
!Please note
To prevent equipment damage,
install all pipework free of load
and torque stresses.
For on-site preparation of gas,
water and electrical connections,
see installation aid or mounting
frame installation instructions.

Minimum clearances
Area around the Vitodens for mainte-
nance: min. 700 mm.
Maintenance clearances to the l.h. or r.h.
side of the Vitodens are not required.
Note
This boiler (protection: IP X4 D) is
approved for installation in wet rooms
inside safety zone 2 according to the cur-
rent I.E.E. Wiring Regulations.
The requirements of the I.E.E. Wiring
Regulations must be observed.
1. Prepare the water connections. Flush
the heating system thoroughly.
2. Prepare gas connection in compli-
ance with the The Gas Safety (Instal-
lation and Use) Regulations 1998.
3. Prepare the electrical connections.
■Power supply cable: 3 x 1.0 mm2,
2 m long is fitted in the delivered
condition.
Fuse max. 16 A, 230 V~, 50 Hz.
■ Accessory cables: e.g. type NYM
cable with the required number of
conductors for the external con-
nections.
■Allow all cables in area "G"
(behind the boiler) to protrude
1200 mm from the wall.

Note
If the gas condensing boiler is to be oper-
ated in weather-compensated mode and
with a DHW cylinder, connect the DHW
cylinder at cylinder flow B and cylinder
return D (four pipe connections).
Flue installation and connection
Connect the appropriate flue system as
per our flue gas system installations.
During installation and positioning of the
flue gas system, observe building regu-
lations part L and BS 5440 as well as the
flue gas system installations which are
provided with the boiler.
Flue gas system installation
instructions.
Connecting the safety valve drain/blow-off pipe

Connect safety valve A with visible out-
let to the household drain system or
route with visible outlet through the
external wall.

Connect the condensate drain with a
slope and a pipe vent to the public
sewer.
Observe the Building Regulations.
Where the condensate drain pipe is
routed outside, it must have a diameter
of at least 30 mm and must be protected
against frost through sufficient lagging of
the pipe. Avoid excessive pipe runs at
the outside wall.
Gas connection
A
Notes regarding operation with LPG.
We recommend the installation of an
external safety solenoid valve when
installing the boiler in rooms below
ground level.
1. Seal in gas shut-off valve A at the
gas connection.
2. Carry out a tightness test.
Note
For the tightness test, use only suita-
ble and approved leak detecting
agents (EN 14291) and devices.
Leak detecting agents with unsuita-
ble constituents (e.g. nitrites, sul-
phides) can lead to material dam-
age.
Remove residues of the leak detect-
ing 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 sup-
ply pipe (undo the fitting).

For the connection, observe the
separate installation instructions
provided with the accessory com-
ponents.

Danger
Incorrect cable core termina-
tion can cause severe inju-
ries and damage to the
equipment.
Never interchange cable
cores "L1" and "N".
■ Install an isolator in the power
supply line which simultaneously
separates all non-earthed con-
ductors from the mains with con-
tact separation of at least 3 mm.
We additionally recommend
installing an AC/DC-sensitive
RCD 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 con-
nection 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 connec-
tion is directly controlled with the
system ON/OFF switch (max. 3
A).
