Using your Hestan KRG485-NG range is a breeze. First, make sure it's properly connected to the natural gas supply and the power source. To start cooking, turn the burner knobs to set the desired heat level. The 5 burners offer great temperature control, and the 12-inch griddle is perfect for searing and grilling. When using the oven, set the temperature between 150°F and 550°F according to your recipe. The PureVection™ technology will do its job to bake, broil, or roast your food evenly. For safety, always keep flammable items away from the range. Don't forget to clean the range regularly. The removable burner caps and oven door make cleaning easy. Wipe the stainless steel surface with a mild cleaner to keep it looking new. And if you notice any issues with the ignition or gas supply, turn off the range immediately and call a professional.
