It is the 1" or 11/8" hex nut on the top of the water heater some where buy the supply line. As for the anode rod it could be either magnesium or aluminum depending where it was sold. If you are going to change it out call your water provider and ask which would be better for your area and water. To remove you need to turn off the electric, shut the water supply and drain off some of the water so it wont overflow, then it simply unscrews. Use teflon tape or sealer on the thread before installing the new one, then turn everything back on and purge the air from the system by opening a faucet.

While it's very likely that one manufacturers flammable vapor sensor may interchange on another brand of tank, I think it's highly unlikely that EVERY manufacturers sensor will work on every other brand of tank
