Service This hob should only be repaired or serviced by an authorised Service Engineer and only genuine approved spare parts should be used. During Use This hob is intended for domestic cooking only. It is not designed for commercial or industrial purposes. This appliance is not connected to a combustion products evacuation device. It must be installed and connected in accordance with current installation regulations. Particular attention shall be given to the relevant requirements regarding ventilation. When in use a gas cooking appliance will produce heat and moisture in the room in which it has been installed. Ensure there is a continuous air supply, keeping air vents in good condition or installing a cooker hood with a venting hose. When using the hob for a long period of time, the ventilation should be improved, by opening a window or increasing the extractor speed. Do not use this hob if it is in contact with water. Do not operate the hob with wet hands. Keep the appliance clean. Food residuals increase the risk of fire. Ensure the control knobs are in the `OFF' position when not in use. When using other electrical appliances, ensure the cable does not come into contact with the hot surfaces of the cooking appliance. 2 Contents For the User Important Safety Information Description of the Hob Operation Maintenance and Cleaning Something Not Working?

Step by step instructions for an operation Hints and Tips Enviromental information This appliance complies with the following E.E.C. Directives: * 73/23 - 90/683 (Low VoltageDirective); * 93/68 (General Directives); * 89/336 (Electromagnetical Compatibility Directive); * 90/396 (Gas Appliances), and subsequent modifications 3 Description of the Hob 1 2 1 4 1. Semi-rapid Burners 2. Rapid Burner 3. Auxiliary Burner 4. Control knobs 3 4 Operation Hob burners To light a burner: push in the relevant control and turn it to maximum position; then adjust the flame as required. If the burner does not ignite, turn the control knob to zero, and try again. If you use a saucepan which is smaller than the recommended size, the flame will spread beyond the bottom of the vessel, causing the handle to overheat. Take care when frying food in hot oil or fat, as the overheated splashes could easily ignite. As soon as a liquid starts boiling, turn down the flame so that it will barely keep the liquid simmering. If the control knobs become difficult to turn, please contact your local Service Centre. Avoid cooking with potstones, earthenware pots or cast iron plates. Also, avoid using aluminiun foil for protecting the top during operation. To ensure maximum burner efficiency, you should only use pots and pans with a flat bottom fitting the size of the burner used (see table). Burner minimum diameter 180 mm. 120 mm. 80 mm. maximum diameter 260 mm. 220 mm. 160 mm. Large (rapid) Medium (semi-rapid) Small (Auxiliary) Maintenance and Cleaning Before any maintenance or cleaning can be carried out, you must DISCONNECT the hob from the electricity supply. The hob is best cleaned whilst it is still warm, as spillage can be removed more easily than if it is left to cool. This appliance cannot be cleaned with steam or with a steam cleaning machine. The Burners The burner caps and crowns can be removed for cleaning. The cap and crown of each burner are secured with two screws. To separate the two pieces, lift the crown, turn it upside down, then undo the two fixing screws as shown in Fig. 1. After cleaning, reassemble the two parts and refit the cap on its correct position on the burner. Wash the burner caps and crowns using hot soapy water, and remove marks with a mild paste cleaner. A well moistened soap impregnated steel wool pad can be used with caution, if the marks are particularly difficult to remove. After cleaning, be sure to wipe dry with a soft cloth. The Hob Top Regularly wipe over the hob top and the aluminium frame using a soft cloth well wrung out in warm water to which a little washing up liquid has been added. Avoid the use of the following: - household detergent and bleaches; - impregnated pads unsuitable for non-stick saucepans; - steel wool pads; - bath/sink stain removers. Should the hob top become heavily soiled, it is recommended that a cleaning product such as Hob Brite or Bar Keepers Friend is used. If scratches or cracks are noticed on the glass top, immediately disconnect the appliance from the electrical supply, contact your local Service Force Centre and avoid using the appliance until it has been repaired. Pan Supports The pan supports are dishwasher proof. If necessary, remove stubborn stains using a paste cleaner. Never use steel wool pads or acids. Pay attention when replacing the pan supports in order to avoid scratching the glass hob top. Fig. 1 FO 2265 5 Something Not Working?

Detailed recommendations are contained in the following British Standards Codes Of Practice: B.S. 6172/ B.S. 5440, Part 2 and B.S. 6891 Current Editions. Location The hob may be located in a kitchen, a kitchen/diner or bed sitting room, but not in a bathroom, shower room or garage. Before making the cut out in the worktop ensure that the edges of the hob that are to be near either a side or rear wall have a minimum distance of 55 mm. between the edge of the hob and the wall. The minimum distance combustible material can be fitted above the hob is 400 mm. If it is fitted below 400 mm. a space of 50 mm. must be allowed from the edges of the hob. The minimum distance combustible material can be fitted directly above the hob is 700 mm. A minimum distance of 100 mm. must be left between the side edges of the hob and any adjacent cabinets or walls. Provision for Ventilation The hob should not be installed in a bed sitting room with a volume of less than 20 m3. If it is installed in a room of volume less than 5 m3 an air vent of effective area of 110 cm2 is required. If it is installed in a room of volume between 5 m3 and 10 m3 an air vent of effective area of 50 cm2 is required, while if the volume exceeds 11 m3 no air vent is required. However, if the room has a door which opens directly to the outside no air vent is required even if the volume is between 5 m3 and 11 m3. If there are other fuel burning appliances in the same room, B.S. 5440 Part 2 Current Edition, should be consulted to determine the requisite air vent requirements.

The manufacturer will not accept liability, should the above instructions or any of the other safety instructions incorporated in this book be ignored. Gas Connection Connection to the gas supply should be with either rigid or semi-rigid pipe, i.e. steel or copper. The connection should be suitable for connecting to RC 1/2 (1/2 BSP male thread). When the final connection has been made, it is essential that a thorough leak test is carried out on the hob and installation. Ensure that the main connection pipe does not exert any strain on the hob. It is important to install the elbow correctly, with the shoulder on the end of the thread, fitted to the hob connecting pipe. Failure to ensure the correct assembly will cause leakage of gas. WHEN THE HOB IS FIRST INSTALLED Once the hob has been installed, it is important to remove any protective materials, which were put on in the f ...
