I found this document http://www.fire.nist.gov/bfrlpubs/fire83/PDF/f83003.pdf to be some really interesting reading. An in depth study and report of flue fires, over fires, and there affect on chimneys and nearby combustibles. The study was done in 1983, but I have not seen anything like it more recent. Tests were conducted using all types of chimneys. I know, you have to be addicted but I have already been diagnosed, so here it is. Oh, by the way....I found especially interesting the finding at the bottom of page 9 regarding creosote buildup relationship between dry wood and wet wood.....you are not going to like it! (and I have a real hard time believing it, although the study seems to be quite thorough and legitimate)
NO I AM NOT TELLING, you have to read it yourself ;-P
