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,

Gas Safety (Installation & Use) Regu-

lations the appropriate Building Regu-

lationeither the Building regulations,

theBuilding Regulation (Scotland),

Building Regulations (Northern Ire-

land), 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 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

5513 085 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.

Intended use

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 050-W, type BPJC

Preset for operation with natural gas.

Conversion to LPG P requires a gas con-

version kit.

Gas Council no.

■ 29 kW combi: 47 819 31

■ 35 kW combi: 47 819 32

Conversion for other countries

The Vitodens 050-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 050-W is available as a

gas condensing combi boiler with inte-

gral plate heat exchanger for DHW heat-

ing. For the connection of heating circuits

and DHW line, see page 12 onwards.

The Vitodens 050-W is set up for opera-

tion with a constant boiler water temper-

ature.

The appliance is equipped with a sealed

unvented hydraulic system with 2 con-

nections for heating flow and return and

2 connections for DHW heating.

The following components are integra-

ted into the hydraulic system:

■ Circulation pump

■ 3-way diverter valve

Preparing for installation

5513 085 GB

Installation

■ Safety valve

■ Diaphragm expansion vessel

■ Plate heat exchanger for DHW heating

Connecting accessories

A time switch (accessories) can be con-

nected to the control unit with a low volt-

age supply.

Siting

Suitable siting locations include:

■ Recreational rooms and other living

spaces

■ Ancillary rooms without own ventila-

tion

■ Cupboards (open at the top)

■ Recesses without compulsory clear-

ance towards combustible materials

■ Attic rooms (pitched attics and long

panes) where the balanced flue can be

routed directly through the roof

Since the flue pipe connection for room-

sealed operation is surrounded by com-

bustion air (coaxial pipe), no clearances

towards combustible materials need be

maintained. For further details, see the

technical guide "Flue systems for the

Vitodens".

The installation area must be safe from

the risk of frost.

The Vitodens is approved for installation

in wet rooms (e.g. bathroom or shower

rooms) (protection IP X4 D, splash-

proof).

When installing the Vitodens in wet

areas, observe the safety zones and

minimum wall clearances according to

VDE 0100 [or local regulations] (see also

"Electrical safety zone"). The Vitodens

may be installed in area 1 if hosed water

(e.g. from massage showers) is preven-

ted.

Preparing for installation

Preparing for installation (cont.)

5513 085 GB

Electrical equipment in rooms containing

a bathtub or a shower must be installed

in such a way that users cannot be

exposed to dangerous body currents.

VDE 0100 specifies that cables supply-

ing permanently installed consumers in

zones 1 and 2 should only be run verti-

cally and routed into the equipment from

the back.
