I bought this very used gas oven/range for $10. I gutted it, removing the bottom and top burners and welded the bottom broiler door solid. I made a charcoal maze basket to fit in the very bottom, from the rear. (where the broiler compartment is) I've used it for a food warmer and to smoke bacon with. I've done some research and some deck ovens have a corderite "roof" above the deck floor. What is the floor itself made out of? Steel? Anodized or coated with something? Any suggestions on lining the oven? Maybe the thin firebrick? Maybe put my Primo round stone near the top, with firebrick overhead? Or a steel deck with firebrick overhead? Any ideas are welcome.
