Thanks for the feedback. To tell the truth, I don't know if it is going to fit or not. It is only slightly taller than my 5gal pot, though. So I hope it makes it.
I was thinking the same as you. Yes, 150-170 is hotter than ambient, but I have to assume if it is good to go on a turkey fryer it can handle some hotter-than-ambient temps. Also, there is going to be some conduction of heat from boiling water inside the pot, so the dial is going to get pretty hot anyway.
Thanks again for the feedback.
P.S. I did a bunch of searching after posting and didn't find anything, so I feel marginally better about asking a question without doing any research.
