Complete Replacement Pilot Assembly for a Direct Vent Fireplace. Used by Superior/Lennox part number 69L17 (natural gas). This fits the Natural Gas Nova SIT Direct Vent valves. This includes the thermopile (main valve sensor), fine thread thermocouple (pilot sensor), ignitor wire and ceramic probe, and the pilot tube. This includes the bracket that goes next to the burner which holds it all together. Pilot tube, thermocouple, thermopile, and ignitor wire are about 24" long. Look at your bracket to ensure it is the same. This has a side mount bracket to attach it to the fireplace.
