Always begin by opening the lid to prevent gas from building up in the cooking chamber.
If using a grill fueled by liquid propane, completely open the valve on the top of the propane tank by turning the knob counter-clockwise until it stops.
If your grill has an igniter button, simply turn the first burner knob all the way up and push the button.
For grills that don’t have an ignition button, use a long fireplace match or a lighter wand to light the initial burner after turning it on.
Once the first burner is lit, turn the other burners on high.
Close the lid and allow the temperature to heat up for 10- to 15-minutes.
