EXT is the Mixing valve Atwood, BUT, that would NOT cause a LONG time to heat. IF it runs for 2 hours and the water is NOT hot, then either the LP pressure is too low or the burner is not set up for correct flame. But if it shuts OFF after 2 hours and the water is NOT hot, that points to a defective tstat also. The tstat should not open until the water is 130/140 degrees. Doug
