Hey there! If you're dealing with a wall heater or fireplace that won't light, this Ganivsor ODS pilot assembly might be exactly what you need. This is a direct replacement for part numbers 104286-01, PP224, LPG8420, L98310-01, and J3866 - it's identical to the OEM parts but without the crazy price tag. It works with a ton of popular brands including Comfort Glow, Comfort Flame, Desa, FMI, Reddy, Vanguard, and Vantage vent-free heaters and fireplaces. The LPG8420 design can even replace the older LPG8402 models. Super important though - make sure you get the right pilot assembly for your specific heater model number. These things are built with quality materials to ensure your heater works properly and safely. Installation is straightforward if you're handy, but if you're not comfortable working with gas lines, definitely call a professional. The ODS (oxygen depletion sensor) is crucial for safety in vent-free heaters, so having a properly functioning pilot assembly is pretty important. This replacement part offers the same high quality and longevity as the original, so you won't be dealing with the same issue again in a few months. Whether your current pilot is damaged, corroded, or just not working right, this replacement will get your heater firing up properly again. Just remember to turn off the gas and electricity before you start working, and double-check that this part matches your specific heater model before ordering!
