I noticed today that my spa heater will not go above 104. We don't have the propane tank full and usable yet, but the other day I was able to get the spa up to 103 with solar heat, and it wasn't *that* hot. So I'm worried that 104 isn't going to be enough heat for me.

Any way to bypass the 104 max temp governor? The gas co. guy today said that with some other heater type, you can get it up to 106 using some kind of trick (Some dip switch on a circuit board). He wasn't sure about my Jandy LX heater. Anyone know the "trick"? Is > 104 dangerous to pool equipment or finishes or chemistry?
