This also fits Heatilator, and other fireplaces in the Hearth and Home line up. This is for Natural Gas. Review: Pay attention closely to the models in the description. - Note the models that this fits in the description. For my model (8000TR-OAK), it says only for serial numbers pre 00211XXXX. I have a post serial number and this did not work on mine. While it all fits fine, the pilot orifice is different and the flame was too small to get proper voltage from the thermopile. So don’t ignore the serial number blocks on the models. I purchased a different on for the post serial number block and it works perfectly. I am still rating this five starts because it works fine, just not for my model. Review: Replacement Part for Heat-N-Glow 8000trc - I replaced the pilot assembly on my 1999 Heat-N-Glo 8000trc gas fireplace. This item is a plug and play. I was able to replace the pilot assembly without disconnecting any gas lines, although I did shut the gas off. For the customer who said in her review that the gas line was crimped on her item, the line that she was referring to was not a gas line. The thermopile does connect with a copper tube, and is crimped on purpose so that you don't try to connect that part to gas. The thermopile copper tube was crimped on my assembly too. The pilot line (silver aluminum line) is the only gas line in this assembly. I did seal the bracket holes that the lines run through with the supplied gaskets and some Permatex 81630 Ultra Red High Temperature Gasket Maker (bought on desertcart). After a few bloody knuckles, I soap tested the pilot connection and all gas connections. Works like a charm. Pilot has been running for a week and the fireplace starts up with the flip of a switch each time. I did not need to adjust the pilot flame, but it is only the turn of a screw if need be. ## Features - Natural Gas - Replaces 485-510A - Pilot tube, thermocouple, thermopile, and ignitor wire are about 24" long. - Fine thread thermcouple ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B017GNO2MU | | Best Sellers Rank | #527,273 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #401 in Furnace Replacement Ignitors | | Brand | Heatilator | | Brand Name | Heatilator | | Color | Black | | Customer Reviews | 4.6 out of 5 stars 284 Reviews | | Form Factor | Cabinet | | Fuel Type | Natural Gas | | Heating Coverage | 25 square feet | | Heating Element | Radiant | | Heating Method | Radiant | | Indoor Outdoor Usage | Indoor | | Indoor/Outdoor Usage | Indoor | | Manufacture Year | 2000 | | Manufacturer | Heatilator | | Model Number | 4021-736 | | Mounting Type | Floor Mount | | Part Number | 4021-736 | | Power Source | Gas Powered | | Recommended Uses For Product | Home | | Room Type | Kitchen | | Special Feature | Portable | | Special Features | Portable | | UPC | 735255592733 | ## Product Details - **Brand:** Heatilator - **Color:** Black - **Form Factor:** Cabinet - **Indoor/Outdoor Usage:** Indoor - **Special Feature:** Portable ## Images ![Heatilator & Heat-N-Glo Natural Gas Pilot Assembly 4021-736 - Image 1](https://m.media-amazon.com/images/I/71FXJ7-ZcIL.jpg) ## Questions & Answers **Q: Would this work on heatilator model # gndc30 nat** A: No, you want to use 4021-732 which can be found on Amazon.
