I am converting a double upright commercial oven/warmer to a wood smoker. I plan on having a 2x2 firebox. Piping into each compartment with either 2 or 3 in pipe. I'm going to use some kind of kind of switch to cut off or adjust the amount of heat to each compartment. Have the exhaust come from each compartment joining to one. Wondering if I need to change out the insulation out. Since it was a oven figured it would be high temp insulation. Comments and suggestions appreciated.
