It's natural gas and I'm not sure if it shuts off the flow its self. The stove is low end, but only a year old. I figure there is something I could do to the stove to shut it off, but wasn't sure how. I also have no clue where the manual is.

I'm also horrible at identifying smells. I have smelled natural gas before, but am unable to recognize weather what I smell is that. What ever it was though, the smell is gone now.

Who knows, one of our animals may have just had really bad gas.
