At the heart of every Weber gas barbecue is a unique burner system found on no other barbecue in the world. Itís this unique, revolutionary and patented Flavorizerô system that distinguishes our barbecues from all the others. Specially angled Flavorizer bars form a roof over the gas burner tubes so that no meat juice or fat comes in contact with the gas flame. Follow our directions and this system allows for healthy, fat free cooking with incredible flavour. Meat juices sizzle and smoke on the hot bars, yet excess fats fall harmlessly into the disposable drip tray below. Not many people know that there is one other feature of our cooking system that separates our barbecues from all the others. Itís the scientifically vented hood. This enhances flavour in a way that you canít get when you cook in the open. Cooking with a Weber hood down ensures that the smoke trapped underneath it is circulated all around the meat before leaving the barbecue. This is how you get that famous Weber flavour. On those occasions when you want to create a beautiful roast or finish off the perfect steak, simply turn off the centre burner(s) directly under the food (this is our indirect barbecue cooking) and allow the heat to circulate barbecue smoke evenly all around the meat for unbelievable flavour.
