There are two ways to set up your grill for grilling- over direct and over indirect heat. For foods that takes under 20 minutes (think burgers, steaks, fish, chicken breast) you will use a method called direct heat. The direct heat method means that food is cooked directly over the burner tube.
So how do you set up your grill for direct cooking?
• Open the lid of your gas grill and make sure all control knobs are in the off position.
• Slowly open the valve on your propane tank all the way or turn on the gas at the source and then wait a minute for the gas to travel through the gas line.
• Light each burner individually, from left to right, following the owners guide instructions for your grill model.
• Close the lid.
• Preheat the grill for 15 minutes, or until the grill’s thermometer registers 500° to 550°F.
• Brush the cooking grates with a stainless steel grill brush to remove any leftover debris.
• Adjust all burners to the temperature noted in the recipe, close the lid, and allow the grill to come to the proper temperature.
• Place food on the cooking grate.
• Close the lid of the grill and lift it only to turn food or to test for doneness at the end of the recommended cooking time.
