Hi everyone, i am searching for some advice. I want to transform a Stainless steel freezer into a smoker. It is a True, model T-23. This will have an internal propane burner. After removing all of the electrical items, condenser etc... do you think i need to remove the CFC free polyurethane foam from the walls and replace it?. My biggest worry is that if it would be toxic. I do not want to contaminate the meat. I do not have this freezer yet, so i do not know how much work it will be to dismantle the walls. I am hoping that i do not have to. Any ideas would be very helpful.
