GENERAL INFORMATION 3

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 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:

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

The boiler contains no asbestos and no substances used in the construction process that

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

1988).

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

rear of the Installation, Commissioning and Servicing Instructions.

GENERAL INFORMATION

INTRODUCTION

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

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 trap within the boiler via a pump and pipe

to drain. This pipe must not be blocked or

altered in any way.

CLEARANCES - SERVICE

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.

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 (TRV)

TRVs should fitted to all but one of the

radiators (or at least those in the sleeping

accommodation). The radiator without the

TRV must be in the same room as the room

thermostat, and must be uncontrolled and

unrestricted. 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, but 600mm to a

fixed surface for servicing.

** This space can be reduced to 50mm for

one side only as long as both side clearances

add up to the total of both the side

measurements shown, or more.

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.

In spite of 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.

BOILER CLEARANCES -

AIRING CUPBOARD

If the boiler is fitted into an airing cupboard

then the diagram opposite shows the minimum

clearances required around the boiler and

also the clearances for any shelf constructed

above the boiler.

If a compartment is built around the boiler

after installation, then the compartment must

be separated from the boiler space by a non-

combustible partition as described in BS 6798.

WARNING

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. This is to reduce the possibility

of pump seizure during long periods of

inactivity which are usually more frequent

during the summer months.
