5772 980 GB 4/2013 Please keep safe.

Please follow these safety instructions closely to

prevent accidents and material 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 environmental pollution.

Note

Details identified by the word "Note" contain additional

information.

Target group

These instructions are exclusively intended for quali-

fied 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 electrician.

■The system must be commissioned by the system

installer or a qualified person authorised by the

installer.

Regulations

Observe the following when working on this system:

■Statutory regulations regarding the prevention of

accidents

■Statutory regulations regarding environmental pro-

tection

■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

■Gas Safety (Installation & Use) Regulations

– the appropriate Building Regulation either the

Building regulations, the Building Regulation (Scot-

land), Building Regulations (Northern Ireland),

– the Water Fittings Regulation or Water Bylaws in

Scotland,

– the current I.E.E. Wiring Regulations.

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. 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 supply utility from

outside the building.

■Shut off the electricity supply to the building

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 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 conden-

sate or other causes. Ensure a sufficient supply of

combustion air.

Instruct system users that subsequent modifications to

the building characteristics are not permissible (e.g.

cable/pipework routing, cladding or partitions).

Danger

Life-threatening poisoning caused by carbon

monoxide in the flue gas occurs as a result of

leaking or blocked flue systems or an insufficient

supply of combustion air.

Ensure the flue system is in proper working

order. It must not be possible to close apertures

for interconnected combustion air supply.

Extractors

Operating appliances that extract air to the outside

(cooker 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 a sufficient supply of combustion air.

Safety instructions

5772 980 GB

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.

!Please note

Electronic assemblies can be damaged by elec-

trostatic discharge.

Prior to commencing any 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 your

system.

Defective components must be replaced 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.

The appliance is only intended to be installed and

operated 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 the heating of water that is

of potable water quality.

Intended usage 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 does not comply with

regulations.

Any usage beyond this must be approved by the man-

ufacturer for the individual case.

Incorrect usage or operation of the appliance (e.g. the

appliance being opened by the system user) is prohibi-

ted and results in an exclusion of liability. Incorrect

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, B2KA

Preset for operation with natural gas E and

natural gas LL.

For conversion to LPG P (without conversion kit), see

"Commissioning, inspection, maintenance".

In principle the Vitodens 200-W may only be delivered

to countries listed on the type plate. For deliveries to

alternative countries, approved contractors must

arrange individual approval on their own initiative and

in accordance with the law of the country in question.

Note

This boiler (IP rating: IP X4 D) is approved for installa-

tion in wet rooms inside safety zone 1 according to

DIN VDE 0100. Exposure to water jets must be pre-

vented.

Observe the requirements of DIN VDE 0100.

1. Fit the pre-plumbing jig or mounting frame provided

at the chosen installation site.

Pre-plumbing jig or mounting frame installa-

tion instructions

2. Prepare the connections on the water side for the

valves on the pre-plumbing jig or mounting frame.

Thoroughly flush the heating system.

3. Prepare the gas connection according to TRGI or

TRF [or local regulations].

Preparing for installation

5772 980 GB

Installation

4. Prepare the electrical connections. ■Power cable: NYM-J 3 x 1.5 mm2, max. fuse rat-

ing 16 A, 230 V, 50 Hz.

■Accessory cables: NYM with the required number

of cores for the external connections.

■All cables should protrude 1200 mm from the wall

near "G".

HSafety assembly

A safety assembly H to DIN 1988 and EN 806 is

required if the mains water supply pressure exceeds

10 bar (1.0 MPa), and no DHW pressure reducing

valve is installed (to DIN 4753).

Only use a non-return valve or a combined shut-off

and non-return valve in conjunction with a safety valve.

If the safety valve is used, the cold water shut-off valve

on the boiler must not be shut off.

Remove the toggle on the cold water shut-off valve (if

installed) to prevent it being shut off manually.

Shock arrestor

If draw-off points that could cause pressure peaks

(water hammer/shock) are connected to the same

pipework as the boiler (such as pressure washers,

washing machines or dishwashers), we would recom-

mend the installation of a shock arrestor near the

source of such pressure shocks.

g: Fit a small domestic expansion vessel if water

hammer occurs.
