I had mistakenly thought the "fines box" referred to the space that opened with 2 bolts under the burnpot (burnpot front cover?) and I've been vacuuming it out, but now realize that's not the fines box. So.... where is the fines box on my Absolute 43c located and how do I clean it? Trying to learn as much as I can so I can maintain my stove correctly. Thanks for any help!
