Appliance description

The Vitodens 200-W is a fully automatic,

wall hung, fan assisted balanced flue

condensing boiler for use with natural gas

(G20) and LPG. For gas type

conversions see page 63.

The Vitodens 200-W is fully modulating

and provides central heating outputs

between 4.8kW and 35.0kW and

instantaneous hot water outputs

between 4.8kW and 35.0kW.

The appliance always gives priority to

domestic water supply.

Certification details

The Vitodens 200-W is certified to comply

with the requirements of EN 483 and

EN 625 for use in GB and IE (Great

Britain and Ireland) using gas category

2H (G20 with a governed gas supply at

20 mbar (8 in. wg) inlet pressure).

The appliance is designed for use with

sealed primary water systems (only) and

incorporates a circulation pump, diverter

valve assembly, flow switch (combination

boiler only), DHW plate-type heat

exchanger (combination boiler only),

safety valve and CH expansion vessel.

A separate DHW expansion vessel is not

required. Internal frost protection and

an electronic control unit is fitted as

standard equipment and the boiler may

be used with any suitable room

thermostat, cylinder thermostat

and / or time clock in addition to the

optional controls available from

Viessmann.

Asbestos, mercury or CFCs have not

and will not be used in this product.

The appliance classification is either

C13 or C33 depending upon whether

a horizontal or vertical flue terminal is

used.

Safety instructions

Please follow these safety instructions closely to prevent the risk of

accidents and material damage.

Safety instructions explained

Danger

This symbol warns against the

risk of injury.

Please note

This symbol warns against the

risk of material damage and

environmental pollution.

Note

Details identified by the word ‘Note’

contain additional information.

Target

These instructions are exclusively

designed for qualified personnel.

• Work on gas equipment must only

be carried out by a CORGI registered

heating engineer.

• Electrical work must comply with

Part P of the building regulations.

• The system must be commissioned by

a CORGI registered heating engineer.

If you notice a smell of gas

Danger

Escaping gas can cause

explosions which may lead

to serious injury.

• Do not smoke. Prevent

naked flames and sparks.

• Do not operate electrical

switches or equipment.

• Ventilate the area by

opening the windows and

doors.

• Close the gas supply

control valve.

• Remove all personnel from

the danger zone.

• Observe the safety

regulations of your gas

supplier, found on the gas

meter.

• Notify your CORGI

registered heating engineer

or TRANSCO on 0800 111

999.

If you smell flue gas

Danger

Flue gas may lead to

life-threatening poisoning.

• Shut down the boiler and

system

• Ventilate the area.

• Close all doors in

unaffected areas.

• Do not operate electrical

switches or equipment.

5350 485 GB 06/2007

Safety instructions (cont.)

Working on the system

• Close the main gas shut-off valve

and safeguard against unauthorised

reconnection.

• Isolate the system from the electricity

power supply, check that it is no longer

‘live’ and safeguard the electricity

supply against unauthorised

reconnection.

Please note

Electronic modules can be

damaged by electro-static-

discharges. Touch earthed

objects, such as heating or

water pipes, to discharge

static loads ensuring any

appropriate electrical safety

steps have been taken in

advance.

Repair work

Please note

Repairing components which

fulfil a safety function can

compromise the safe

operation of your heating

system. Replace faulty

components only with original

Viessmann spare parts.

Ancillary components

Please note

Parts which have not been

tested together with the

heating system can

compromise its function.

Installing non-authorised

components and non-

approved modifications/

conversions can compromise

safety and may invalidate the

appliance warranty. For

replacements, use only

original spare parts from

Viessmann or those which

are approved by Viessmann.
