COMBUSTIBLE AND CORROSIVE MATERIALS

Do not store or use any combustible materials (paper, thinners, paints etc.) inside or within

the vicinity of the boiler.

Chemically aggressive substances can corrode the boiler and invalidate any warranty.

FITTING & MODIFICATIONS

Fitting the boiler and any controls to the boiler or removal of the outer casing may only be

carried out by a competent engineer in accordance with the Gas Safety (Installation and Use)

Regulations.

Flue systems must not be modified in any way other than as described in the fitting instructions

Any misuse or unauthorised modifications to the boiler, flue or associated components and

systems could invalidate the warranty.

The manufacturer accepts no liability arising from any such actions. This does not affect your

statutory rights.

GENERAL NOTES

GENERAL NOTES

INTRODUCTION

SERVICING

The boiler must be serviced regularly by a competent, qualified person, such as a Worcester

service engineer or alternatively a British Gas or other CORGI registered person.

Always use original spares, to help maintain the economy, safety and reliability of the boiler and

to have the Service Record completed in the Benchmark checklist.

IMPORTANT: - Ensure that the service engineer completes the Service Record in the

Benchmark checklist after each service.

The completed Benchmark checklist will be required in the event of any

warranty work and may be required by the local Building Control Inspector.

NOTE: The Benchmark checklist and service interval record can be found at the

rear of the Installation, Commissioning and Servicing Instructions.

BENCHMARK STANDARD

‘Benchmark’ is a code of practice for correctly installing, commissioning and servicing of

domestic water heating boilers.

A Benchmark checklist is provided by the manufacturer for the installer to complete ALL details

together with their CORGI registration number and sign to confirm that the boiler has been

installed and commissioned according to the manufacturer’s instructions.

HEALTH & SAFETY

No asbestos or other hazardous substances are used in the construction process that

contravene the COSHH Regulations (Control of Substances Hazardous To Health Regulations

1988).

GENERAL NOTES

To get the best from your boiler please

read these instructions carefully.

SEALED HEATING SYSTEMS

If this boiler is fitted to a sealed heating

system which is pre-pressurised. Your

installer will advise you of the minimum

and maximum pressure which should be

indicated on the system pressure gauge.

Check regularly that the pressure is

maintained and contact your installer or

maintenance engineer if a permanent

significant drop in pressure is indicated

on the pressure gauge. If the system

loses pressure it should be re-pressurised

and the cause of the fall investigated.

CENTRAL HEATING SYSTEMS

During the first few hours of operation of

the central heating system, check that all

radiators are being heated evenly. If the

top of a radiator is at a lower temperature

than the bottom then it should be vented

by releasing air through the venting screw

at the top of the radiator. Ask your

installer to show you how this is done.

This boiler is fitted to a sealed system;

repeated venting will reduce the quantity

of water in the system and this must be

replenished for safe and satisfactory

operation of the boiler.

Should water leaks be found in the

system or if excessive venting is required,

then a service engineer must be

contacted to inspect the installation and

rectify any fault.

Only additives that are compatible with

aluminium may be used in the system. Any

incompatible additive used will invalidate

the guarantee.

CONDENSATE DRAIN

This is a condensing boiler and the

terminal will, at times give out a plume of

water vapour. This is quite normal.

The boiler also produces quantities of

condensate which is discharged regularly

by a syphon within the boiler via a pipe to

drain. This pipe must not be blocked or

altered in any way.

CLEARANCES - VENTILATED

COMPARTMENT

Your installer will have provided adequate

space around the boiler for safety and

servicing access. Do not restrict this

space with the addition of cupboards,

shelves etc. next to the boiler.

GENERAL NOTES

ROOM THERMOSTAT

A room temperature controller and

programmer should be fitted to control the

central heating. Refer to the instructions

supplied with the thermostat for

information on siting and setting.

THERMOSTATIC RADIATOR VALVES

It is recommended that this type of valve is

fitted to all but one of the radiators (or at

least those in the sleeping

accommodation). The remaining radiator,

which must be where the room thermostat

is located, should be un-controlled and

must be left open. The thermostatic

radiator valves should conform to the

requirements of BS2767:10.

BOILER CLEARANCES -

UNVENTILATED COMPARTMENT

The diagram opposite shows the

minimum space required to install and

service the boiler inside an unventilated

compartment.

** Space required for unventilated areas

with a removable door or panel.

*** 600mm clearance required to a fixed

surface for servicing.

* The boiler must have more clearance in

the unventilated compartment compared

to the ventilated compartment.

Two examples are shown opposite, refer

to the “Installation, commissioning and

servicing instruction manual” for further

information.

Do not add cupboards, shelves etc. to

restrict the space around the boiler.

VENTILATION

This is a room sealed boiler and does not

require any air for combustion from inside

the property. If the boiler is fitted into a

cupboard or a compartment is built

around the boiler after installation, then

the compartment must be separated from

the boiler space by a perforated non-

combustible partition as described in BS

6798.

Notwithstanding the requirements of BS

6798 and BS 5440 there is no need for

ventilation openings to be provided in the

compartment because of the low heat

loss from the boiler casing, if the

clearances shown are maintained.

Do not operate the boiler if the flue

terminal fitted on the outside wall or roof

is obstructed or damaged.

PUMP ANTI-SEIZURE

If there has been no heating demand for

24 hours the boiler will run the system

pump for a few seconds to reduce the

possibility of pump seizure during long

periods of inactivity, which is usually more

frequent during the summer months.

The blue indicator light goes out.

SETTING THE CENTRAL HEATING

TEMPERATURE

Turn the central heating temperature

control to the desired level, the

range is between approximately

35°C and 82°C.

When the burner is lit, the green

indicator light underneath the on/off

knob is illuminated.

CONTROLLING CENTRAL HEATING

Set the timer to the correct time.

Set room thermostat to the desired

room temperature.

Set the thermostatic radiator valves

to the desired settings.

FROST PROTECTION

Leave main power knob on.

If the temperature falls to below 5°C

within the boiler the boiler will fire

periodically to avoid the possibility of

freezing.

If remote pipework is exposed to

low temperatures, ensure that the

installer has added a frost

thermostat.

FAU LT CONDITION

In the unlikely event of a fault occurring

while the boiler is in operation:

The mains indicator will flash at different

speeds dependant on fault.

To r e s e t f a u l t t u r n t h e t h e r m o s t a t /

reset knob fully anticlockwise to

“reset” and then return the knob to

the desired temperature setting.

The indicator will stop flashing and

the boiler will function normally,

dependant on programmer and

room thermostat settings.

If the electrical power to the boiler has

been interrupted a “reset fault”

condition will exist. Reset the boiler as

described above.

If the fault remains and cannot be

cleared:

Call Worcester, Bosch Group for

assistance, giving a description of

the fault and, if possible the fault

flashing sequence from the mains

indicator.
