Below is a picture of the basic valve extension when installing the 1/4 turn manual valve in to a fire pit with a wall thicker than the standard key will reach.
All you need to do is add a 3/4″ coupler and the proper length of pipe nipple to reach the inside of your gas fire pit. These items can be found at any hardware store that carries gas piping. Just add a longer key to reach the valve.
