New to me, but overall was in really nice condition. I took it apart to clean, inspect, and lighten to move. well, I didnt realize all the components essentially just "holding" in place behind the rear plate. SO my question is, how does it all go back together? There seems to be insulation just stuffed in the corners along with long piece just laying there. is that supposed to be there? and where does that metal grate piece go? then there are also gaskets that look a bit rough. around the top exhaust piece and around the rear baffle. thanks for any help!
