If your Heatilator gas fireplace or stove isn't lighting properly, this pilot assembly might be exactly what you need to get things working again! This is the genuine replacement part number 25660 designed for natural gas systems. It comes complete with everything you need - the pilot tube, thermocouple, thermopile, and ignitor wire all in one assembly. The extra long 4-inch ceramic electrode sparker makes installation easier and ensures reliable ignition. This part is specifically designed for Heatilator fireplaces and stoves, so you know it will fit and function perfectly. Before ordering, definitely double-check that this matches your specific model and that you have a natural gas system (not propane). Installation does require some mechanical knowledge and always remember to turn off the gas supply before working on any gas appliance. If you're not comfortable doing it yourself, definitely hire a professional. But if you're handy and your pilot light has been giving you trouble - not staying lit, weak flame, or not igniting at all - replacing the entire pilot assembly is often the most reliable solution. This quality replacement part will have your fireplace or stove working like new again, bringing back that cozy warmth to your home. Much more affordable than calling a repair service for what might be a simple fix!
