A few months back I had 6 pork bellies going in my Landmann 38 wide. I was out doing yard work while it was going. After sometime I came buy just to check the temps. When I walked up I noticed ash by my right vent. Odd. Kicked and sure enough ash came out. looked at the left vent, ash also. Weird. Pulled the bottom drawer and there was still wood chucks in it, but the extra heat seal I added just fell off. Now this is really weird. Propane was still going and internal temp was 220. WTH. I open the door to see what was up and the whole thing was black and smelled like soot. I guess some fat dripped down and ignited. All the belly lit up and most of burned super hot! Luckily it starved itself of oxygen. It also helps that I had done a mod and wrapped the whole think in a welders blanket. No other issues, but I ruined a ton of bacon....
