GENERAL DESCRIPTION

(See Fig.1.) The WORCESTER 24i or 28i is a combined domestic hot water and central heating appliance. It consists of a gas fired boiler having a varying output of between 7.5 kW and 23.4 kW (24i) or 8.5 kw and 27.5 kw (28i), a combined heat-exchanger and all necessary controls to provide mains fed domestic hot water and central heating. The appliance can operate in one of two modes as required. Hot water only or hot water and central heating.

Hot Water Mode:

When a demand is made for hot water by opening a tap or shower the flow switch will energise and the burner will light at its maximum setting. When hot water is no longer required the appliance pump and fan may continue to operate to dissipate the excess heat within the boiler.
A flow restrictor is fitted within the appliance which limits the hot water delivery rate to a maximum of 8.0 (15%) litres/minute (1.8 gallons/minute) 24i or 10 (15%) litres/minute (2.2 gallons/minute) 28i.
Hot Water and Central Heating mode:
When a demand is made for heating by the system controls (i.e. a programmer or room thermostat). The pump will energise circulating primary water around the heating system and the burner will light. The heat output from the appliance in this mode has been factory set to maximum. The appliance will operate as necessary to maintain the temperature of the radiators at the level set by the adjustment of the Heating Temperature Control Knob. (See Fig. 2.) If the system no longer requires output to maintain the desired room temperature, the burner will extinguish. The pump and fan will continue to run for a short Automatic period to dissipate the air vent residual heat from the appliance and then switch off. The appliance will supply heat to the central heating system as required. A demand for hot water at a tap or shower will override the central heating function for Boiler the period of the domestic hot water demand.

GENERAL NOTES

CENTRAL HEATING SYSTEM

During the first few hours of operation of the central heating system, check that all radiators are being heated at an even rate. Should the upper area of a radiator be at a lower temperature than the base of the radiator, it should be vented by releasing air through the venting screw at the top of each radiator. Make sure your installer shows you how to carry out the operation. 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 be required from any radiator, a service engineer should be contacted and the system corrected.

SEALED HEATING SYSTEM

The appliance will be fitted to a sealed heating system which is pre-pressurised. Your installer will advise you on the minimum and maximum pressure that should be indicated on the pressure gauge. See Fig. 2. Check regularly that this pressure is maintained and contact your installer or maintenance engineer if there is a permanent significant drop in pressure indicated on the gauge. If the system loses pressure it should be re-pressurised as instructed by the installer (N.B. Maximum pressure 2.5 bar).

CLEARANCES

Your installer will have provided adequate space around the appliance for safety and servicing. Do not restrict this space by the addition of cupboards, shelves etc. close to the appliance. Minimum clearances in millimetres. RSF 200

ROOM THERMOSTAT

A room thermostat may be fitted for control of the central heating temperature. It will be located in one room of the home. The method of setting a room thermostat varies with the type and manufacture. Refer to the instructions supplied with the room thermostat.
THERMOSTATIC RADIATOR VALVES
If thermostatic radiator valves are to be fitted to the system then they must conform to the requirements of BS2767:1972. It is advisable to leave one valve permanently set at maximum to prevent the boiler short cycling.
SHOWERS, BIDETS, TAPS AND MIXING VALVES
Standard hot and cold taps and mixing valves used with the appliance must be suitable for operating at the available mains pressure. Thermostatically controlled or pressure equalising shower valves will guard against the flow of water at too high a temperature. Hot and cold mains fed water can be supplied direct to an overrim flushing bidet subject to local water company requirements. With all mains fed systems the flow of water from the 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.

HOT AND COLD FLOW

If the flow of water demanded from both hot and cold service outlets is dependent upon mains supply, it may not be possible in some installations to operate all outlets simultaneously.

WATER MAINS FAILURE

It is important to note that in the event of a mains water supply failure, no tap water will be available until the mains supply is restored.

USE IN HARD WATER AREAS

In temporary hard water areas (more than 350mg/litre or 200ppm calcium bicarbonate) it is recommended that a proprietary scale reducer is fitted in the mains cold water connection to the appliance. Consult the local water company for additional advice. Installation of a scale inhibitor assembly should be in accordance with the requirements of the local water company. An isolating valve should be fitted to allow servicing. The water hardness can be determined by reference to the local water company.
DOMESTIC HOT WATER TEMPERATURE CONTROL
By slightly reducing the flow of domestic water from the tap, the delivery temperature will be increased. This is of particular advantage in the winter, for example to increase bath water temperature and to remove heavy grease deposits on plates, etc. Also this will provide an added advantage of reducing the delay before hot water is obtained.
VENTILATION OF THE APPLIANCE
This is a room sealed appliancem, any ventilation openings in a wall or door must not be obstructed. Do not allow the flue terminal fitted on the outside wall to become obstructed or damaged. If the appliance is fitted in a compartment do not use the compartment for storage purposes unless it conforms to the requirements of BS 6798:1987: Section 6 and the requirements of Section 6. Air Supply in the Installation Instructions. It is essential that the airing space is separated from the boiler space by a perforated non-combustible partition as described in BS 6798:1987. NOTE: Do not place anything on top of the appliance.

CIRCULATING PUMP

This may be fitted with a speed adjuster. If so it will be factory set at maximum and should not be changed.

FROST PRECAUTIONS

Your British Gas Engineer, or any service engineer will advise you on suitable frost precautions. For short periods the built-in frost protection of the appliance will be adequate. If the appliance is not to be used for a long period of time and there is a likelihood of freezing, then the appliance should be drained.

SERVICE

Annual servicing is important in order to ensure continuing high efficiency and long life for your appliance. In the event of any difficulty in making suitable servicing arrangements, Worcester Heat Systems Limited, your British Gas Engineer or other competent persons will discuss regular servicing arrangements and offer a comprehensive maintenance contract. IMPORTANT: Do not touch or adjust any sealed component.

WARNING

If a gas leak exists, or is suspected, turn off the gas supply to the appliance at the service cock and consult your local British Gas Engineer or service engineer. Do not touch any electrical switches to turn them either on or off. Open all windows and doors. Do not smoke. Extinguish all naked lights.

CLEANING

Do not use abrasive cleaners on the outer casing. Use a damp cloth and a little detergent.

OPERATION OF CONTROLS

(See also label on inside of appliance front panel). The appliance is fitted with the following controls:
CENTRAL HEATING TEMPERATURE
The position of this knob will determine the temperature of the water delivered to the radiators between the I and MAX position. When the knob is turned anti-clockwise past the I position towards the (Summer Position), then the appliance will operate in the HOT WATER mode only and no heat will be delivered to the radiators.
FACIA MOUNTED PROGRAMMER (if fitted)
Your installer may have fitted a mechanical programmer into the facia of your appliance. Operating instructions are supplied with the programmer.

SYSTEM PRESSURE GAUGE

The red needle has been set to show the sealed system pressure which is required for the appliance to operate effectively. The grey needle will show the actual pressure in the system.

INDICATOR LIGHT

Mains electricity indicator: OFF : No mains electricity to the appliance ON : Mains electricity is connected to the appliance FLASHING : Sensor fault.
OVERHEAT CUT-OFF THERMOSTAT
The appliance will enter a lockout condition in the event of overheating. An overheat cut-off thermostat is fitted to the appliance which will interrupt the electricity supply to the ignition circuit. If the overheat cut-off has operated the fan and/or pump will run but the burner will not light. (No spark generation). The appliance can be reset by pressing the overheat cut-off button.

TO STOP THE APPLIANCE

For Short Periods Turn the central heating temperature control knob fully anticlockwise to the position. Domestic Hot Water will still be available as required. For Long Periods Switch off the mains electricity. A facia mounted mechanical programmer will require resetting once the mains supply has been disconnected.
ELECTRICITY SUPPLY FAILURE
If the electricity supply fails the appliance will not operate. Once the supply is restored the appliance will return to normal operation. If a programmer is fitted, check that the settings have been maintained.

IGNITION LOCKOUT

The appliance will enter a lockout condition in the event of the burner failing to ignite. If the burner fails to light within a preset time of 10 seconds the electricity supply to the gas valve will be interrupted. The appliance can be reset by ending the present demand which in a central heating demand means turning the central heating temperature control to and back to the required setting or ending the room thermostat/programmer demand. Re-ignition will be attempted after a delay of four minutes. Domestic hot water demands do not have this delay. Check that the gas supply has not been interrupted. If this condition continues to occur, then call a service engineer.

AIR FLOW DEVICE

The appliance will enter a lockout condition in the event of an air flow fault. If the controls fail to detect the correct air flow through the appliance the electricity supply to the gas valve will be interrupted. The appliance will try to re-light once the air-flow signal is reestablished. Check that the flue terminal has not been obstructed or damaged, and that the fan and air pressure switch are in good order. If this condition continues to occur, then call a service engineer.
REMOVAL AND REPLACEMENT OF THE FRONT PANEL (See Fig. 3)
Necessary to check if burner is lit. Removal: Holding the panel at the edges, slide it upwards to disengage the clips and ease the top edge forwards and upwards to raise it clear of the two pegs on the top edge of the facia. Replacement: Locate the two holes in the bottom edge of the front panel over the two pegs on the top edge of the facia and reverse the removal procedure. WARNING: Do not touch any component within the appliance when it is running as some may be very hot.
