I was hot and fast smoking a spatchcocked turkey when I went out to check the temperature only to find flames shooting outside of the smoker!
My pellet smoking tube rolled up against the side of the smoker which caused the grease/smut in the crease between fire box and the smoke box to catch fire. It was literally a ring of fire on the inside and outside of my smoker where the two boxes are bolted together. Cut off and disconnected the propane tank right away thinking that it may settle down, but nope. It was growing, so I had to get the fire extinguisher involved.
As a testament to all of those people that say they can't get a pellet tube to stay lit - check out Todd's! In the last pic you can see it still belching out beautiful smoke even after being hit with a fire extinguisher! I say this in total jest and still swear by Todd's stuff - it was the positioning of the tube that caused my issue. I just found it funny that it started smoking again about 30 minutes after being hit with a fire extinguisher yet some people can't seem to get them lit....
No one hurt and I expect the smoker will clean up just fine. Just an experience and a good reminder to keep a working fire extinguisher around just in case.
