The maximum you wrote above appears to be in the context of boiling off any water, since it is after a
sentence that discusses the minimum (temp) to boil off any water. The laws of physics describe
boiling points, operating limitations do not need to, since these exist in nature. It is physically
impossible to boil water above 212F at Sea Level Pressure, since if the temp is higher than that it
has already boiled. That maximum temperature of water in the liquid state decreases as pressure
decreases, i.e. increased pressure altitude.

Sorry if I was not clear. 180F is the temperature that the oil temp guage must indicate to start
boiling off water. 212 (or as some have pointed out 220 for other installations) is the limit set
by the manufacturer to keep the oil from getting too hot (nothing to do with boiling water).

While liquid water won't ever get above the boiling point, remember that this guage isn't stuck in
water, it's stuck in oil. If you put water in 350 degree oil it will burn off. Anybody who has deep
fried something is quite familiar with this effect.
