Cooking on a gas grill has many advantages over traditional charcoal. It is convenient and simple to learn to use, provides an even cooking heat and there is little wait time to preheat. Here is how to set up and use your gas grill.

Prepare your grill. Make sure that the grill is set securely on a level surface, 10 to 15 feet from any dwelling or structure. Arrange the lava rocks in the bottom of the grill according to the grill manufacturer's instructions, and place the cooking grill over the rocks.

Attach the propane tank. Inspect the gas line for any signs of wear or cracks; if in doubt, do not use your grill. Check that the control valve is tightly closed. Place the tank on the tank platform of the grill with the valve opening facing the grill connection. There are several types of valve connection; you will need to refer to the manufacturer's instructions to determine the type. Commonly, a screw type valve connection is used and the process is as simple as attaching the line to the valve with a screw nut.

Check the connection. You can either use a store-bought soap solution or mix a soap solution of water and dish soap. Apply this solution to the connection of the valve, then open the control valve. If bubbles appear in the soap solution on the valve, do not operate your grill, and close the valve. If no bubbles appear, the connection does not have a gas leak, and should be safe to use.

Light the grill. Make sure the propane control valve is open. Open the grill lid. Turn the gas flow control on the grill on to full and immediately press the lighter switch. If your grill does not come with a lighter switch, manual grill lighters can be purchased at your local hardware store. The gas will ignite and your grill is now ready to use. If the gas does not ignite immediately, turn off the gas control knob and wait before trying again.

After use, turn the propane control knob off first, then turn the gas flow control on the grill off.
