N.B. The key must always be removed from the filling loop housing after the system has been filled to prevent accidental filling and to comply with Bylaw 14 of the Water Bylaws Scheme. Store the key in a safe place for future use and refit the bottom panel. OPEN VENTED HEATING SYSTEM The appliance may be fitted to an open vented heating system your installer will advise you. There is no need to observe the pressure gauge.

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. 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 fitted to the system then they must conform to the requirements of BS2767. The radiator located in the room where the room thermostat is sited must be controlled by a thermostatic radiator valve. SHOWERS, BIDETS, TAPS AND MIXING VALVES Standard hot and cold taps and mixing valves used with the appliance must be suitable for operating at mains pressure. Thermostatically controlled shower valves will guard against the flow of water at too high a temperature. If using a pressure equalising valve, set the Domestic Hot Water temperature control knob to the ‘MAX’ position. Hot and cold mains fed water can be supplied direct to an over- rim 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 The Worcester Technical Helpline. 08705 266241 HOT AND COLD FLOW 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. The appliance can still be used for heating provided that the system is of the sealed system type. Open vent central heating systems should be turned off until the supply is restored. USE IN HARD WATER AREAS Normally there is no need for scale protection. However, in areas of exceptionally hard water supply it is recommended that an In-Line scale inhibitor be fitted. Installation should be strictly in accordance with the requirements of the local Water Company. An isolating valve to facilitate servicing should be incorporated. The water hardness may be determined using the standard test paper or by reference to the local Water Company. Further information may be obtained from Worcester Bosch Technical Helpline. AIR SUPPLY FOR OPEN FLUED (O.F.) APPLIANCES Your installer will have made arrangements for an adequate supply of fresh air to the appliance. Fresh air is required for combustion. Do not block up any air ways which may be let into a wall or door. Do not hang clothes or other combustible materials over the appliance or against the flue pipe. NOTE: Do not place anything on top of the appliance. 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. In particular, the flue pipe should not pass through an airing cupboard space unless protected by a guard (such as wire mesh) concentrically spaced 13mm (1/2in), as described in BS 6798:1987. VENTILATION OF BALANCED FLUED (BF) AND ROOM SEALED FANNED FLUE (RSF) APPLIANCES These are room sealed appliances and 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. NOTE: Do not place anything on top of the appliance. 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. 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. 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 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 dra...
