This Criditpid natural gas pilot assembly is exactly what you need if your fireplace has stopped working properly. It replaces part numbers 4021-736 and 485-510A, and it's compatible with a huge range of Heat N Glo, Heatilator, and Quadrafire gas fireplace models. The installation is straightforward if you're comfortable with basic gas appliance repairs - just make sure to turn off the gas supply first! The thermopile is 36 inches long, and the pilot tube, thermocouple, and ignitor wires are about 24 inches, giving you plenty of length to work with. The quality seems solid - it's not some cheap knockoff that'll fail quickly. I used this to fix my Heatilator fireplace that hadn't been working for months, and it fired up perfectly on the first try. The copper tubing is durable but remember to be gentle during installation - don't bend it excessively to avoid damage. What's great is how comprehensive the compatibility list is - it works with dozens of different fireplace models from multiple brands. Whether you're dealing with a pilot light that won't stay lit or need to replace an aging assembly, this part delivers reliable performance. It's much more affordable than calling a professional for the same repair, and the instructions are clear enough for most DIYers to handle. Just remember - this is for natural gas systems only, and if you're not comfortable working with gas lines, it's always best to hire a professional. For the price and compatibility, this pilot assembly is an excellent value for fireplace owners needing repairs!
