I bought this oven three years ago and it still is not hooked-up. Been doing small pieces on an extended home-style oven. The bigger oven is 5’x4’x6′ and will run on natural gas. I’m thinking of just having my HVAC guy help me change the orifice and run propane in a larger size tank for now until I get this thing dialed-in. Also been eyeballing the electric ovens by Tedsfabrication but I already have this unit. Any suggestions?
