Sorry no pics yet, I just have some simple questions about setup. 1. Do I need an intake damper at the bottom of the fridge? 2. I have seen where sombody had added a rheostat to a hotplate for temp control, can somebody remember where that post is, I have searched and came up empty? 3. My fridge has a large open space undernieth where the compressor used to be. My plan is to cut a square hole in the bottom of the fridge. have a steel box made to drop in. the bottom of the box will hold the heating element. I plan on having a drip pan about 3" above the bottom of the fridge. Will that work as my heat deflector also? 4. I am going to use a smoke daddy for a smoke generator, can that penetrate anywhere around the bottom of the fridge? Above or below the drip pan?
