Part number 19 on Schematic

Service Note: The stack flue sensor, located on the exhaust elbow of a pool heater, prevents the flue gas output from exceeding 500°F. When this fails, your system will show error codes E05 or E06 to  indicate that the stack flue sensor must be replaced.

Note: This is a Generic part and much cheaper that the originals. We carry both, but this is a much  better deal, so our recommendation.
