If you have a Lennox, Elite, Merit, Serefina, Superior, or Astria gas fireplace that needs a new pilot assembly, this ALLPARTS replacement is exactly what you're looking for. The 69L17 natural gas pilot assembly comes completely assembled and ready for installation by your HVAC professional. This tri-directional pilot features a 653 series side mount bracket, 24-inch pilot tube, 34-inch electrode with ceramic cable, 24-inch 750 MV thermo-generator, 24-inch 30MV thermocouple, and the proper NG pilot orifice. It replaces old part numbers 69L1701 and 904405, but important note - this is an SIT aftermarket assembly that only works with SIT Nova 820 series gas valves and requires an 11/32 thermocouple connection. The quality construction ensures reliable ignition and consistent performance for your fireplace. Cross-references with multiple Lennox and related part numbers, making it compatible with various direct vent fireplaces, gas logs, and inserts from brands like Empire Comfort Systems, Travis Industries, Cozy, Majestic, Martin and others. While designed for professional installation, having the correct part number ready can save time and money on your repair. The complete assembly means everything you need is in one package rather than sourcing individual components. If your fireplace pilot light isn't functioning properly or you're doing maintenance on an older unit, this quality replacement part can restore reliable operation and ensure your fireplace lights safely every time.
