Please follow these safety instructions closely to prevent accidents and mate-

rial 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 envi-

ronmental pollution.

Note

Details identified by the word "Note" con-

tain additional information.

Target group

These instructions are exclusively inten-

ded for qualified 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 elec-

trician.

■ The system must be commissioned by

the system installer or a qualified per-

son authorised by the installer.

Regulations

Observe the following when working on

this system:

■ Statutory regulations regarding the

prevention of accidents

■ Statutory regulations 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

aÖNORM, EN, ÖVGW-TR Gas,

ÖVGW-TRF and ÖVE

cSEV, SUVA, SVGW, SVTI,

SWKI, VKF and EKAS guideline

1942: LPG, part 2

If you smell gas

Danger

Escaping gas can lead to explo-

sions 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

supplier and your local heating

contractor from outside the

building.

■ Shut off the electricity supply to

the building from a safe place

(outside the building).

Safety instructions

5585 174 GB

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 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 condensate or other

causes. Ensure a sufficient 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 insufficient supply of com-

bustion air can cause life threat-

ening poisoning from carbon

monoxide in the flue gas.

Ensure the flue system is in

proper working order. Apertures

for supplying 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 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 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 or service

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.

Before beginning 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.

Faulty components must be

replaced with original 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 the

warranty.

For replacements, use only orig-

inal spare parts supplied or

approved by Viessmann.

5585 174 GB

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 usage 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 does not comply with regulations.

Any usage beyond this must be

approved by the manufacturer for the

individual case.

Incorrect usage or operation of the appli-

ance (e.g. the appliance being opened

by the system user) is prohibited and

results in an exclusion of liability. Incor-

rect 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

Preset for operation with natural gas E

and natural gas LL.

For conversion to LPG P (without con-

version kit), see the service instruc-

tions.

In principle the Vitodens 200-W may

only be delivered to countries listed on

the type plate. For deliveries to alterna-

tive countries, approved contractors

must arrange individual approval on their

own initiative and in accordance with the

law of the country in question.

Multi boiler system

For the installation of a multi boiler sys-

tem observe the installation instructions

for the multi boiler system accessories.
