Turn the fuel valve on the propane tank counterclockwise to release the flow of gas to the grill.
Turn the burner control knobs on the front panel to the "Start" or similar position, then press the igniter button to light the grill. You can also use a butane grill lighter with a long metal tube to light the grill burners.
Adjust the side and top vents on the grill to the fully open position. This maximizes air flow to oxygenate the flames.
Close the grill cover and dial the burner control knobs on the front panel clockwise to the highest setting. Wait 10 minutes for the internal heat to increase to the maximum temperature possible, then open the grill and place food on the cooking grate.
