This document describes a built-in gas hob, designed for cooking purposes in private households and domestic environments. The appliance offers various features for efficient and safe cooking, along with guidelines for proper use and maintenance.
The gas hob is equipped with multiple burners, including standard-output, high-output, and a dual-wok multi-crown burner, allowing for a range of cooking intensities. Each burner is controlled by a dedicated control knob, which enables users to adjust the flame height incrementally from the lowest to the highest power level. The dual-wok multi-crown burner provides independent control over its inner and outer flames, offering enhanced flexibility for different cooking needs.
The hob features automatic ignition for the burners. To ignite a burner, the user presses and turns the control knob anti-clockwise to the highest level, holding it down for a few seconds until the flame ignites. A safety system, incorporating a thermocouple, automatically interrupts the gas flow if a burner flame accidentally goes out, ensuring safety. In the event of a power cut, burners can be manually ignited using a lighter or match.
The appliance is designed for use with appropriate cookware, which should be centred on the pan supports and not protrude over the edge of the hob. The document provides recommendations for suitable cookware diameters for each burner type to ensure optimal performance and energy efficiency. Accessories such as an additional wok grid, an espresso maker grid, and a simmer plate are available to enhance the hob's versatility for specific cooking tasks.
The control knobs are central to operating the hob, allowing precise adjustment of flame intensity. The highest power setting (indicated by '9') is used for initial cooking processes like boiling water, starting soups, or high-temperature frying. Intermediate settings (e.g., '4-6') are suitable for continuing cooking, deep frying with less oil, stewing, or cooking at medium temperatures. The lowest power setting (indicated by '1') is ideal for melting delicate ingredients like butter or chocolate, or for keeping food warm.
The dual-wok multi-crown burner's independent flame control allows users to tailor the heat for wok cooking, where different heat zones are often required. For instance, setting the outer flame to minimum and the inner flame to full power (indicated by '4') provides a concentrated heat for specific tasks, while both flames at full power ('9') deliver maximum heat for rapid cooking.
Safety is paramount in the hob's design and usage. Users are advised to ensure adequate ventilation in the kitchen, especially during intensive or prolonged use, to prevent the build-up of heat, moisture, and combustion products. It is crucial to never leave cooking fat or oil unattended due to the risk of fire. The document also warns against using hob covers, heating empty cookware, or placing flammable objects near the hot appliance. In case of a gas smell or fault in the gas installation, immediate actions include shutting off the gas supply, extinguishing flames, avoiding electrical switches, ventilating the room, and contacting professional service.
Regular cleaning and servicing are essential to maintain the appliance's efficiency and longevity. The document provides detailed instructions for cleaning the hob, burners, and pan supports.
For general cleaning, the appliance should be allowed to cool down, then cleaned with a sponge and soapy water, and dried with a soft cloth. It is important not to remove the control knobs during cleaning to prevent moisture ingress that could damage the appliance's interior. Users are cautioned against using harsh, abrasive detergents, steel wool, knives, or sharp objects, as these can damage the surfaces. Steam-cleaning appliances are also not recommended.
The burner parts should be cleaned after each use to prevent food remains from burning on. After cooling, they can be cleaned with a non-metallic brush and soapy water, then thoroughly dried. It is crucial to ensure that the burner parts are correctly positioned after cleaning, with burner caps properly seated on the flame spreader, to ensure a correct flame. The burner holes and grooves must be kept clean. The document explicitly states that burner parts should not be cleaned in a dishwasher.
Pan supports also require regular cleaning. After cooling, they should be carefully removed and cleaned with a non-metallic brush and soapy water. The area around the rubber pads on the pan supports should be cleaned carefully. Alternatively, pan supports can be cleaned in a dishwasher using recommended cleaning agents, with pre-cleaning advised for heavy soiling. After cleaning, the pan supports must be completely dry before being reinserted.
The document also includes a troubleshooting section to help users identify and rectify minor faults, such as issues with automatic ignition, uneven burner flames, or gas supply problems. For more complex issues or repairs, users are advised to contact customer service, emphasizing that repairs should only be carried out by trained specialist staff using genuine spare parts.
