Trying to fix a natural gas fireplace that wasn't working that well. And it was really old. I've included pictures to help. It is vented. I have the grate and gas logs. I definitely need a new burner, sand. Might be a good idea to upgrade the pilot light system but I believe it works. If I keep the old one might be a good idea to get a new thermocouple and supply line to the pilot light. Just looking to be pointed in the right direction. I was leaning to ordering something like the following.
