A natural gas fire pit? That ain't right! OK to each his own, but just like gas grilling is not charcoal grilling a gas fire pit ......well you might as well just put a picture there. I bought a deep wide copper fire pit years ago and it is still fine. I burn oak and birch for the smell. A gas fire pit to me is like making love to one of those plastic dolls. I know they are popular because they are easy and clean and don't throw sparks and easily turned off, but it just is not the same as a real campfire. I am not telling you what to do. And I wish you well with your project. I am just inputting how I feel about outdoor fire pits.
