2 General information

2.1 Energy efficiency

Energy efficiency information is given in the Installation,

Commissioning and Servicing Instructions supplied with the

appliance.

2.2 Servicing

• The appliance must be serviced regularly by a competent,

qualified person, such as a Worcester service engineer or

other Gas Safe registered engineer.

• Always use original spares, to help maintain the efficiency,

safety and reliability of the appliance and have the Service

Record completed in the Benchmark Checklist.

The completed Benchmark Checklist will be required in the

event of any guarantee work and may be required by the local

Building Control Inspector.

2.3 Benchmark standard

The Benchmark initiative is a

code of practice to encourage

the correct installation,

commissioning and servicing of

domestic central heating

appliances and system

equipment.

A “checklist” is dispatched with every appliance and can be

found towards the back of the Installation, Commissioning and

Servicing Instructions. This is a vital document that needs to be

completed by the installer at the time of installation. It confirms

that the appliance has been installed and commissioned

according to the manufacturer's instructions.

The service record provides space for the recording of regular

servicing of the appliance/heating system and this can become

a valuable document when, for example, you wish to sell the

property. The service record will show a potential purchaser

that the heating system has received regular professional

maintenance and servicing during its lifetime.

The Benchmark initiative aims to:

• Raise standards among professional installers

• Build and maintain high safety standards in the industry

• Improve customer satisfaction levels

• Make a contribution to the nation's commitment to climate

change

2.4 User caution

• It isforbidden for any interference with the appliance other

than those actions allowed in this document.

Ensure that the service engineer completes

the Service Record in the Benchmark

Checklist after each service. The Benchmark

Checklist and service interval record can be

found at the rear of the Installation,

Commissioning and Servicing Instructions.

CAUTION: Incorrect use

▶ Any incorrect use can result in danger to

the householder.
