You are correct, it does not have an auto shut off. Once you get it up and running let us know how you like it, personally I love mine and I recommend it as a cheap way to get into all grain.
Just make sure to boil water in the aluminum pot before your first use. It has to be done anytime you use aluminum instead of stainless. Besides, it also lets you know what your boil off rate is, which is handy info to have for calculating your starting boil volume.
