BENCHMARK STANDARD

‘Benchmark’ is a code of practice for

correctly installing, commissioning and

servicing of domestic water heating

CORGI registration number and sign to

confirm that the boiler has been instal-

led and commissioned according to the

manufacturer’s instructions.

IMPORTANT: The completed

Benchmark Checklist will be required in

the event of any warranty work and may

be required by the local Building

Control Inspector.

HEALTH & SAFETY

The appliance contains no asbestos and

no substances used in the construction

process that contravene the COSHH

Regulations (Control of Substances

Hazardous to Health Regulations 1988).

SERVICING

The user is recommended to have the

system regularly serviced by a compe-

tent, qualified engineer (such as British

Gas or CORGI registered personnel)

using original spares, to help maintain

the economy, safety and reliability of the

appliance and to have the Service

Record completed in the Benchmark

Checklist.

The appliance should be serviced annu-

ally after installation unless the particular

installation conditions and usage

demand more frequent services.

IMPORTANT - ensure that the service

engineer completes the Service Record

in the Benchmark Checklist after each

service.

INTRODUCTION

GENERAL NOTES

To get the best from your appliance plea-

se read these instructions carefully.

SEALED HEATING SYSTEMS

This appliance is fitted to a sealed hea-

ting system which is pre-pressurised.

Your installer will advise you of the mini-

mum 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-pressuri-

sed and the cause of the fall investiga-

ted.

CENTRAL HEATING SYSTEMS

During the first few hours of operation of

the central heating system, check that all

radiators are being heated at an even

rate. 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

Greenstar CDi (Combi) User.qxd 17.02.2005 9:50 Uhr Seite 8

GENERAL NOTES

WORCESTER BOSCH GREENSTAR 25CDi/30CDi/35CDi/40CDi

6 720 611 928a (02/05)

replenished for safe and satisfactory

operation of the appliance.

Should water leaks be found in the

system or if excessive venting is requi-

red, 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 inva-

lidate the guarantee.

CONDENSATE DRAIN

This is a condensing appliance and the

terminal will, at times give out a plume of

water vapour. This is quite normal.

The appliance also produces quantities

of condensate which is discharged regu-

larly by a siphon 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 adequa-

te space around the appliance for safety

and servicing access. Do not restrict this

space with the addition of cupboards,

shelves etc. next to the appliance.

*600 mm service clearance required to a

fixed surface

(**20 mm from removable door or panel)

BOILER CLEARANCES -

UNVENTILATED COMPARTMENT

The diagrams (A and B) opposite show

two options for the minimum space

required to install and service the boiler

inside an unventilated compartment.

* This space can be reduced to 50 mm

for one side only as long as both the

side clearances add up to the total of

both the side measurements shown or

more.

** Space required for unventilated areas

with a removable door or panel.

*** 600 mm clearance required to a fixed

surface for servicing.

ROOM THERMOSTAT

A room temperature controller and pro-

grammer should be fitted to control the

central heating. Refer to the instructions

supplied with the thermostat for informa-

tion 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 accommo-

dation). The remaining radiator, which

must be where the room thermostat is

located, should be uncontrolled and

must be left open. The thermostatic

radiator valves should conform to the

requirements of BS2767:10.
