tion of accidents
■ Statutory regulations for environmen-
tal protection
■ 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

Safety instructions for working on the
system
Working on the system
■ Where gas is used as the fuel, close
the main gas shut-off valve and safe-
guard it against unintentional reopen-
ing.
■ Isolate the system from the power sup-
ply, 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 recon-
nection.
Danger
Hot surfaces can cause burns.
■ Before maintenance and serv-
ice work, switch OFF the appli-
ance 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 electrostatic dis-
charge.
Prior to commencing work, touch
earthed objects such as heating
or water pipes to discharge static
loads.
Repair work
!Please note
Repairing components that fulfil a
safety function can compromise
the safe operation of the sys-
tem.
Replace faulty components only
with genuine Viessmann spare
parts.
Auxiliary components, spare and
wearing parts
!Please note
Spare and wearing parts that
have not been tested together
with the system can compromise
its function. Installing non-author-
ised components and making
non-approved modifications or
conversions can compromise
safety and may invalidate our
warranty.
For replacements, use only orig-
inal spare parts supplied or
approved by Viessmann.
Safety instructions for operating the
system
If you smell gas
Danger
Escaping gas can lead to explo-
sions which may result in serious
injury.
■ Never smoke. Prevent naked
flames and sparks. Never
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.
■ Have the power supply to the
building shut off from a safe
place (outside the building).
If you smell flue gas
Danger
Flue gas can lead to life threat-
ening poisoning.
■ Shut down the heating system.
■ Ventilate the installation site.
■ Close doors to living spaces to
prevent flue gases from
spreading.

What to do if water escapes from the
appliance
Danger
When water escapes from the
appliance there is a risk of elec-
trocution.
Switch off the heating system by
means of an external isolator (for
example fuse box, domestic
power distribution).
Flue systems and combustion air
Ensure that flue systems are clear and
cannot be sealed, for instance due to
accumulation of condensate or other
causes. Ensure an adequate supply of
combustion air.
Instruct system users that subsequent
modifications to the building characteris-
tics are not permissible (e.g. cable/pipe-
work routing, cladding or partitions).
Danger
Leaking or blocked flue systems,
or an inadequate supply of com-
bustion air can cause life threat-
ening poisoning from carbon
monoxide in the flue gas.
Ensure the flue system is in good
working order. Apertures for sup-
plying combustion air must be
non-closable.
Extractors
Operating appliances that extract air to
the outside (cooker hoods, extractors, air
conditioning units, etc.) can create neg-
ative 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 poison-
ing due to reverse flow of the flue
gas.
Fit an interlock circuit or take suit-
able steps to ensure an adequate
supply of combustion air.

The appliance is only intended to be
installed and operated in sealed unven-
ted heating systems that comply with
EN 12828, with due attention paid to the
associated installation, service and
operating instructions. It is only designed
for the heating of water that is of potable
water quality.
Intended use presupposes that a fixed
installation in conjunction with permissi-
ble, system-specific components has
been carried out.
Commercial or industrial usage for a pur-
pose other than heating the building or
DHW shall be deemed inappropriate.
Any usage beyond this must be
approved by the manufacturer in each
individual case.
Incorrect usage or operation of the appli-
ance (e.g. the appliance being opened
by the system user) is prohibited and will
result in an exclusion of liability. Incorrect
usage also occurs if the components in
the heating system are modified from
their intended use (e.g. if the flue gas and
ventilation air paths are sealed).
Product information
Vitodens 100-W, type B1HA, B1KA
Preset for operation with natural gas.
Conversion to LPG P requires a gas con-
version kit.
Conversion for other countries
The Vitodens 100-W must only be deliv-
ered to the countries specified on the
type plate. For deliveries to alternative
countries, an approved contractor must
arrange individual approval on his/her
own initiative and in accordance with the
law of the country in question.
Product description
The Vitodens 100-W is available as a
gas condensing boiler for the connection
of one DHW cylinder and as a gas con-
densing combi boiler with an integral
plate heat exchanger for DHW heating.
For the connection of heating circuits
and the DHW cylinder or the DHW line,
see from page 13.
In the delivered condition, the
Vitodens 100-W is set up for operation
with constant boiler water temperature.
By connecting an outside temperature
sensor (accessories), the boiler can be
operated in weather-compensated
mode.

Installation
10
The following are integrated: one sealed
unvented hydraulic system with 2 con-
nections for heating flow and return, and
2 connections for cylinder heating (gas
condensing boiler) or DHW heating (gas
condensing combi boiler).
These boilers are only intended for
installation in sealed unvented heating
systems. Boilers for open vented heating
systems are also available.
If the Vitodens 100-W is installed in an S
plan or Y plan system, the DHW primary
connections are not used and must be
capped off.
The following components are integra-
ted into the hydraulic system:
■ Circulation pump
■ 3-way diverter valve
■ Safety valve
■ Diaphragm expansion vessel
■ Plate heat exchanger for DHW heating
(gas condensing combi boiler)
DHW heating with DHW cylinder
If a Viessmann Vitocell is connected, a
cylinder temperature sensor will issue
the heat demand (accessories). The cyl-
inder temperature sensor is connected
to the boiler control unit. A 230 V cylinder
temperature controller is not required.
If a different DHW cylinder is connected,
the cylinder temperature sensor (acces-
sories) may also be used on this cylin-
der. Alternatively, a 230 V cylinder tem-
perature controller should be connected
via the cylinder demand junction box
(part of the boiler standard delivery).
Connecting accessories
Cylinder temperature sensor, outside
temperature sensor and time switch are
connected to the control unit with low
voltage.
