[. . . ] The gas hob is converted to a different gas type by nozzle replacement (full and low-burning nozzles) (see nozzle table on pp. The symbols on the control panel mean: 0 Off High setting Low setting The flame is infinitely variable between high and low-setting. 6 3. Operation The cooking positions must only be ignited when all burner parts are fitted. Switching on: ­ Place a pot or a pan on the corresponding cooking position. ­ Fully press in the control knob for the corresponding cooking position. ­ Turn the control knob to the left to the "high" position. If the flame should not ignite within 2 to 4 seconds, turn the control knob further to the left to the "low" position and then back to the "high" position after ignition. It is often faster to ignite in the low position because the various gases have a differing ignition response. After igniting, keep the control knob pressed for around 5 - 8 seconds more because the heat sensor that opens the gas channel has to warm up first. The flame size can be set continuously between full and low by slowing turning the control knob. Switching off: Fully turn the control knob to the left to the 0 position on the left. Fig. Cleaning and care Please thoroughly clean the appliance before operating it for the first time and after every use. ­ Clean the hob, the burner covers and the pot grid with commercially available cleaning agents (not in a dishwasher!), e. g. ­ As the result of heat development, slight discoloration can appear on the stainless steel surface. Distribute stainless steel care agents uniformly and thinly on the hob (not on the control panel!). This will ensure an even surface and will keep your hob in a good condition for a long period of time. When assembling, place the burner cover (1) on the burner head (2) so that the four tabs on the bottom edge of the burner cover engage in the corresponding tabs on the burner head (see Fig. 6 Wipe off spilt food immediately, thus ensuring that it cannot burn in on the hob. You should only clean the control panel and the control knobs with detergent and a a soft cloth. To ensure perfect functioning, keep the thermal sensor and the spark plug clean. Keep the incoming air openings on the rear of the panel unobstructed and clean. Caution: Never use high-pressure or steam jet units to clean your appliance because otherwise the electrical safety of the appliance will no longer be guaranteed. 8 5. Maintenance 5. 1 General In the event of malfunctions, check whether the gas and electricity supply is in proper working order, i. e. [. . . ] Loads for all gases For all gas types and pressures, the rated load is achieved by installing the high and low setting nozzles for the required gas type (see nozzle table). The low setting nozzle is screwed in fully at the works, and so the lowest quantity is set. Replacing the low-setting nozzle 1 Proceed as follows: ­ Disconnect the appliance from the power supply!­ Remove the cover from the underside of the appliance under the gas valves. [. . . ]
