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.

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 1998

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!

Safety precautions

6 720 610 598 GB (03.11)

Combustible materials

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

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

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 1988).

Ventilation Air/Ambient Air

BKeep ventilation 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.

Sealed heating systems

The appliance is fitted to a sealed heating system which is pre-

pressurised. Your installer will tell you of the minimum and maxi-

mum pressure which must be indicated on the pressure gauge.

Check regularly that the pressure is maintained and contact your

installer or maintenance engineer if there is a permanent signifi-

cant drop in the pressure. If the system loses pressure it should

be repressurised and the cause of the fall investigated.

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.

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.

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.

General notes

6 720 610 598 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 temperature controller may be fitted to control the central

heating. Refer to the instructions supplied with the thermostat for

information of siting and setting.

Cylinder thermostat - System boilers

The cylinder thermostat should be set to 60°C which will be sat-

isfactory for bathing/washing in normal circumstances.

Thermostatic radiator valves

It is recommended that this type of valve is fitted to all the radiators

except one, usually the radiator where the room temperature con-

troller is fitted. They should conform to the requirements of

BS2767:10.

Showers, bidets, taps and mixing valves – Combination

Boilers

Standard hot and cold taps and mixing valves must be suitable for

operating at mains pressure. Thermostatically controlled or pres-

sure equalising shower valves will guard against the flow of water

at too high a temperature.

Hot and cold mains fed water can be supplied directly to an over-

rim flushing bidet subject to local water company requirements.

General notes

6 720 610 598 GB (03.11) TD

With all mains fed systems the flow of water from individual taps

will vary with the number of outlets operated simultaneously and

the cold water mains supply pressure to the property.

Flow balancing using “ball-o-fix” type valves is recommended to

avoid an excessive reduction in flow to individual outlets.

For further information contact Worcester Heat Systems Ltd.

Technical Services Department.

Hot and cold flow – Combination Boilers

The flow of water demanded from both hot and cold service out-

lets is dependent upon the mains supply, it may not be possible in

some installations to operate all outlets simultaneously.

Water mains failure – Combination Boilers

If there is a failure of the mains water supply then no water will be

available at a tap or shower until the mains supply is restored. The

appliance will still operate in the central heating mode.

Use in hard water areas – Combination Boilers

In exceptionally hard water areas a device to prevent scale forma-

tion may be fitted. Installation of a scale inhibitor assembly should

be in accordance with the requirements of the local water com-

pany. An isolating valve should be fitted to allow for servicing.

Alternatively the maximum temperature of the domestic hot water

may be reset to about 45 °C which will reduce the risk of scale

formation in these hard water areas.

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 BS 6798.

Notwithstanding the requirements of BS 6798, there is no need

for ventilation openings to be provided in the compartment

because of the low heat loss from the casing.

General notes

6 720 610 598 GB (03.11)

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

obstructed or damaged.

Pump

The pump is a fully modulating type to which the parameters have

been set by the manufacturer and must not be adjusted.
