Rock On with the Natural Light! I'll post or answer whatever ya need. Before I put the burner in I had a hot plate in it & used Traegers pellets & I wanted to season it hard so that is why it is belching smoke did this every afternoon when I got home from work.
Burner in place with a concrete paver to absorb heat, did it for safety. It is not hot down there. Also see copper tubing instead of a hose.
2x2's support the oven racks (free) from a appliance store. Built the smoker around the LXW of the racks.
