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 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.
■Wear suitable personal protective equipment when
carrying out any work.
Danger
Hot surfaces can cause burns.
■Before maintenance and service work, switch
OFF the appliance 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 elec-
trostatic discharge.
Prior to commencing 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 the
system.
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 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.
Safety instructions for operating the system
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. 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 threatening 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
If water escapes from the appliance there is a
risk of electrocution.
Switch OFF the heating system at the external
isolator (e.g. fuse box, domestic distribution
board).
Danger
If water escapes from the appliance there is a
risk of scalding.
Never touch hot heating water.
Condensate
Danger
Contact with condensate can be harmful to
health.
Never let condensate touch your skin or eyes
and do not swallow it.
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 an adequate supply of
combustion air.
Inform system users that subsequent modifications to
the building characteristics are not permissible (e.g.
cable/pipework routing, cladding or partitions).
Danger
Leaking or blocked flue systems, or an inade-
quate supply of combustion air can cause life
threatening poisoning from carbon monoxide in
the flue gas.
Ensure the flue system is in good working order.
Vents for supplying combustion air must be non-
closable.
Extractors
Operating appliances that extract air to the outside
(extractor 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 an adequate supply of combustion air.

The appliance is intended solely for installation and
operation 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 heating up heating water
that is of potable water quality.
Intended use 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 shall be deemed
inappropriate.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted 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 B1HC, B1KC
Preset for operation with natural gas
The Vitodens 100-W may only be delivered to the
countries specified on the type plate. For deliveries to
other countries, approved contractors must arrange
individual approval on their own initiative and in
accordance with the law of the country in question.
The type plate is located on the top of the boiler (see
page 61).
Product description
The Vitodens 100-W is available as a gas condensing
system boiler for the connection of one DHW cylinder
and as a gas condensing combi boiler with an integral
plate heat exchanger for DHW heating. For the con-
nection of heating circuits and the DHW cylinder or the
DHW line, see page 12 onwards.
In the delivered condition, the Vitodens 100-W is set
up for operation with a constant boiler water tempera-
ture. By connecting an outside temperature sensor
(accessories), the boiler can be operated in weather-
compensated mode.
The following are integrated: one sealed unvented
hydraulic system with 2 connections for heating flow
and return, and 2 connections for cylinder heating (gas
condensing system boiler) or DHW heating (gas con-
densing 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 two internal connections are not used
and must be capped off during installation.
The following components are integrated into the
hydraulic system:
■Circulation pump
■3-way diverter valve
■Safety valve
■Diaphragm expansion vessel
■Plate heat exchanger for DHW heating (gas con-
densing combi boiler)
DHW heating with DHW cylinder
If a Viessmann Vitocell is connected, a cylinder tem-
perature sensor will issue the heat demand (accesso-
ries). The cylinder 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 (accessories) may also be used
on this cylinder. Alternatively, a 230 V cylinder temper-
ature controller should be connected via the cylinder
demand junction box (part of the boiler standard deliv-
ery).
