GBInstallationAll the operations concerned with the installation (electrical and gas connections, adaptation to typeof gas, necessary adjustments, etc.) must be carried out by qualified technicians, in terms with thestandards in force. For specific instructions, kindly read the part reserved for the installation technician.DO NOT FOCUS INTENSE ON THE LEDS AND DISPLAYS.UseUse Gas burnersThe ignition of the gas burner is carried out by putting a small flame to the upper part holes of theburner, pressing and rotating the corresponding knob in an anti-clockwise manner, until the maximumposition has coincided with the marker. When the gas burner has been turned on, adjust the flameaccording to need. The minimum position is found at the end of the anti-clockwise rotation direction.For models with automatic/ simultaneous (with one hand) ignition, it is sufficient to proceed as describedabove using the corresponding knob. The electric spark between the ignition plug and the burnerprovides the ignition of the burner itself. After ignition, immediately release the push-button and adjustthe flame according to need. For models with a thermoelectric safety system, the burner is ignited asin the various cases described above, keeping the knob fully pressed on the maximum position forapproximately 3/5 seconds. After releasing the knob, make sure the burner is actually lit.N.B.- We recommend the use of pots and pans with a diameter matching that of the burner, thus preventingthe flame from escaping from the bottom part and surrounding the pot;- do not leave any empty pots or pans on the fire;- do not use any tools for grill-cooking on Crystal hobs.When cooking is finished, it is also a good norm to close the main gas pipe tap and/or cylinder.DWK modelsModels DWK have a Dual Wok burner. The centre flame (F1) can be lit by pressing the knob andturning it clockwise or the entire burner (F2) can be lit as shown in the figure below.F1F2F1F2F1F2F1F2User instructions4
