Thanks to the guys who have already helped me out getting started. I've got a few threads so far but I'm going to link them all to this one, and upload all pics here. Today I gutted it and took out the tub so I could get a look at the insulation. It's orange and made of fiberglass. Should be perfectly safe, right? Lots of room to stash the electronics and elements, and maybe even the pellet auger! Has anyone left the lightbulb in? Does it do any good after it's covered in smoke?
