Yeah, it's my understanding that the warning to never open or try to refill while hot and attached to the stove wasn't enough and there are enough lawyers who like to take cases from the stupid and make lots of $$'s and force lots of businesses to have to do things to cover their butt's. Can't say I haven't ever done stupid, like the time I was using a stove just like yours and my coffee boiled over and put out the burner, I made the assumption it had just happened and I tossed in a match - well the fireball the ensued and burned a very large hole in the top of my screen tent just screamed Stupid, you weren't watching very closely were you! Oh well, I never thought I should sue Coleman because their stove doesn't have an automatic gas shut off and 25 years later my boys haven't let me forget. Memory makers.
