‘Benchmark’ is a code of practice for correctly installing, commissioning and servicing of domestic water heating appliances.

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.

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).

SAFETY PRECAUTIONS

SERVICING

The user is recommended to have the system regularly serviced by a competent, 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 annually 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.

GENERAL NOTES

GENERAL NOTES

To get the best from your appliance please read these instructions carefully.

SEALED HEATING SYSTEMS

This appliance 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 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

GENERAL NOTES

replenished for safe and satisfactory operation of the appliance.

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.

PLUMING AND 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 regularly by a siphon within the boiler via a pipe to drain. This pipe must not be blocked or altered in any way.

CLEARANCES

Your installer will have provided adequate 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)

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 uncontrolled and must be left open. The thermostatic radiator valves should conform to the requirements of BS2767:10.

GENERAL NOTES WORCESTER BOSCH GREENSTAR 30CDi System

6 720 612 454a (05/10)

GENERAL NOTES

VENTILATION

This is a room sealed appliance and does not require any air for combustion from inside the property. 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 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 appliance casing, if the clearances shown are maintained.

Do not operate the appliance 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.

OPERATING THE

APPLIANCE

WORCESTER BOSCH GREENSTAR 30CDi System

6 720 612 454a (05/10)

Heating economically

The boiler is designed to provide a high level of comfort while keeping gas consumption and the resulting environmental effect as low as possible. The gas supply to the burner is controlled according to the level of demand for heat.

The boiler continues to operate with a low flame if the demand for heat reduces. The technical term for this process is modulating control. Modulating control reduces temperature fluctuations and provides even distribution of heat throughout the home. This means that the boiler may stay on for relatively long periods but will use less gas than an appliance that continually switches on and off.

TIPS ON ENERGY SAVING

Central heating systems with room thermostats/thermostatic radiator valves

The central heating control on the boiler should be set to the maximum rated temperature of the central heating system.

The temperature of each room can be set individually (except primary room with the room thermostat) using the thermostatic radiator valves.

Roof insulation

Around 30% of the heat loss from a property is through the roof. Replace any old insulation with new insulation, preferably of around 200 mm thickness or more.

Window frames

Single glazed windows, particularly those with steel frames, can lose a great deal of heat. Consideration should be given to replacement with PVCu or wooden framed double glazed units.

Curtains

Lined curtains, or heavier full length curtains can provide excellent insulation.

However, always ensure that the curtains do not drape over radiators.

WORCESTER BOSCH GREENSTAR 30CDi System

6 720 612 454a (05/10)

TIPS ON ENERGY

SAVING

17

Draughts

Try to ensure that draughts around doors, windows, letterboxes and keyholes etc. are reduced by using a suitable draught excluder. Warning - Do not block or seal any air vents that are installed to ensure the central heating boiler operates safely.

Room thermostats

Reducing the setting of the room thermostat by 1 °C can reduce fuel consumption by up to 10%.

New control systems

Upgrade your heating control system if necessary with the latest equipment available. The minimum level of control is a programmer, interlocking room thermostat and thermostatic radiator valves.

TIPS ON ENERGY SAVING

Radiators

More often than not radiators will be sited underneath a window, so the warm air from the radiator heats the colder incoming air from the window. The performance of the radiator will be affected if the curtains are allowed to drape over the radiator or shelves are fitted above it.

The positioning of furniture and tables in front of the radiator should also be avoided.

It is advisable to manually adjust all radiator thermostatic valves every 2-3 months to prevent them sticking. It is also important that the plastic tops of all valves are always in position and not cracked or damaged to prevent accidents. Care should be taken when vacuum cleaning carpets to avoid damage to valves and pipework.

The heating system and the outputs of the radiators have been carefully selected by your installer. The temperature obtainable in any given room is dependent on all radiators being operated at the same time. If you decide to turn off radiators in unused rooms, spare bedrooms etc., you may experience slightly lower room temperatures in rooms adjacent to unheated rooms.
