Excellence comes as standard

Thank you for purchasing a Worcester Greenstar condensing

appliance.

The Worcester Greenstar Series has been developed by the

Bosch Group and the strictest quality control standards are

demanded throughout every stage of production.

Indeed, the Bosch Group have led the field in innovative appliance

design and performance for many years.

The result is that your new Greenstar appliance offers you the very

best of everything – quality, efficiency, economical running costs,

proven reliability and value for money.

What’s more, you also have the assurance of our no nonsense

2yearparts and labour guarantee.

And it’s backed up by Worcester Care Call a complete mainte-

nance scheme to keep your boiler operating at peak condition and

efficiency.

No wonder that more and more people are agreeing that when it

comes to gas, it has to be a Worcester Bosch appliance.

Benchmark

The “Benchmark” initiative is the new code of practice to encour-

age the correct installation, commissioning and servicing of

domestic central heating boilers and system equipment.

The “log-book” is a vital document that must be completed by the

installer at the time of installation. It confirms that the boiler has

been installed and commissioned according to the manufacturers

instructions and is one of the methods of demonstrating

compliance with the Building Regulations.

Without the completion of the “log-book”, manufacturers may

refuse to respond to a call–out from a householder, who will be

advised that he or she must call back the installer, who has not ful-

filled his obligations to record the information required by the ini-

tiative.

Safety precautions

Gas Safety (Installation and Use) Regulations

It is the law that all gas appliances are installed by a competent

person in accordance with the above regulations. Failure to install

appliances correctly could lead to prosecution. It is in your inter-

est, and that of safety, to ensure compliance with the law.

If you smell gas:

BTurn off gas service cock at the meter.

BOpen all doors and windows.

BDo not operate any electrical switches.

BDo not smoke.

BExtinguish any naked flames.

BCall your gas company.

If you smell fumes from the appliance:

BSwitch off appliance.

BOpen windows and doors.

BInform your heating engineer.

Fitting and modifications

BFitting of the appliance or any modifications to the appliance

may only be carried out by a competent person.

BFlue systems must not be modified in any way.

Maintenance

BWe recommend that you take out a maintenance contract

with a competent installer and have the appliance serviced at

regular intervals.

BEnsure that your Service Engineer uses only genuine spare

parts!

Combustible materials

BDo not store or use any combustible materials (paper, thin-

ners, paints etc.) in the vicinity of the appliance.

Safety precautions

6 720 611 138 GB (03.11)

Health and safety

BThis appliance contains no asbestos products.

BThere is no potential hazard due to the appliance being electri-

cally unsafe.

BThere are no substances used in the construction that are a

potential hazard in relation to the COSHH Regulations (Con-

trol of Substances Hazardous to Health Regulations).

Combustion Air/Ambient Air

BKeep combustion air/ambient air free of corrosive substances

(e.g. halogenated hydrocarbons which contain chlorine or flu-

orine compounds). In this way corrosion can be prevented.

1General notes

To get the best from your appliance please read these instructions

carefully.

Central heating systems

During the first few hours of operation of the central heating sys-

tem, 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.

Repeated venting will reduce the quantity of water in the system

and this must be replenished for safe and satisfactory operation of

the appliance. An open vented system will re-fill automatically.

Should water leaks be found in the system or 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. Contact Fernox or Sentinel for further details.

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 produces quantities of condense which is dis-

charged regularly through the siphon.

Ventilation

This is a room sealed appliance and does not require any air for

combustion from inside the house. If the appliance is fitted into a

cupboard or a compartment is built around the appliance after

installation then the compartment must be separated from the

boiler space by a perforated non-combustible partition as

described in BS6798.

Notwithstanding the requirements of BS6798, there is no need

for ventilation openings to be provided in the compartment

because of the low heat loss from the casing.

Do not allow the flue terminal fitted on the outside wall to become

obstructed or damaged.

General notes

6 720 611 138 GB (03.11)

Clearances

Your installer will have provided adequate space around the appli-

ance for safety and servicing access. Do not restrict this space

with the addition of cupboards, shelves etc. next to the appliance.

Room thermostat

A room thermostat 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 the radia-

tors. It is a requirement that they are fitted, at least, in the sleeping

areas.They should conform to the requirements of BS2767:10.

Time Control

Separate time control of the space heating and the hot water sys-

tem is required using a twin-channel programmer or two or more

separate timers.

Cylinder Thermostat

A cylinder thermostat must be fitted to the cylinder which, when

used with a motorised valve, will give close control of the water

temperature.

3.2 Switching the Appliance On/Off

Switching on

BSwitch on the appliance at the master switch (I).

The indicator lamp shows green and the display will show the

primary flow temperature.

The trap filling programme ensures that the condensation trap is

filled after the appliance has been installed or after the appliance

has been out of use for a long period. For that reason, the appli-

ance remains at minimum heating output for 15 minutes.

Switching off

BSwitch off the appliance at the master switch (0).

The green indicator lamp goes out.

If the display alternates between -II- and the boiler

flow temperature, the trap filling programme is

active.
