Review: Good quality replacement part.! - Great replacement part..!! Saved over $400 doing it myself compared to the HVAC guys. Took about 45min. Works excellent.. Fits a GTI (Gas Technologies Inc.) Model: R-4500 perfectly. Review: Fixed the problem - Dealt with fire going out spontaneously for far to long. I possibly could have gotten away with only replacing the therocuppler but as long as you are there, might as well replace the whole assembly for not much more dollars. Good decision, works great. ## Features - NG Pilot Assembly for Heat N Glo & Roayl Gas Stoves and Fireplaces - Part #446-510A - OEM HHT Parts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00MOP4ZLO | | Additional Features | OEM HHT Parts | | Best Sellers Rank | #971,830 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #419 in Fireplace Replacement Parts | | Brand | Heat-N-Glo | | Brand Name | Heat-N-Glo | | Color | Silver | | Customer Reviews | 4.6 out of 5 stars 108 Reviews | | Finish Type | Polished | | Finish Types | Polished | | Heat Output | 10000 British Thermal Units | | Heating Element | Natural Gas | | Included Components | Thermocouple, Thermopile, Sparker Electrode, Pilot Tubing | | Installation Type | Built-in | | Manufacturer | HHT | | Manufacturer Part Number | 446-510a | | Material | Aluminum | | Material Type | Aluminum | | Model Name | 446-510A | | Model Number | 446-510A | | Orientation | Rear | | Power Source | Gas Powered | | Shape | Rectangular | | Specific Uses For Product | Indoor | | Style Name | Manual | | UPC | 702535865351 | | Ventilation Type | Vent Free | | Warranty Type | Limited | ## Product Details - **Brand:** Heat-N-Glo - **Color:** Silver - **Finish Type:** Polished - **Heat Output:** 10000 British Thermal Units - **Installation Type:** Built-in - **Material:** Aluminum - **Power Source:** Gas Powered - **Special Feature:** OEM HHT Parts - **Style:** Manual - **Ventilation Type:** Vent Free ## Images ![Pilot Assembly NG (446-510A) - Image 1](https://m.media-amazon.com/images/I/61NgbWvgk6L.jpg) ![Pilot Assembly NG (446-510A) - Image 2](https://m.media-amazon.com/images/I/71QSQ37n6aL.jpg) ![Pilot Assembly NG (446-510A) - Image 3](https://m.media-amazon.com/images/I/71V34qIVW5L.jpg) ![Pilot Assembly NG (446-510A) - Image 4](https://m.media-amazon.com/images/I/61oL7+MptrL.jpg) ## Questions & Answers **Q: Does this assembly unit fit heat and Glo model number SL 36?** A: Assuming you are natural gas, and you have the Robertshaw valve, yes. If you have the SIT valve then the pilot assembly is 571-510a. **Q: Flame intermittently goes out when activated from wall switch. Stays on from internal rocker switch. Will this part resolve?** A: If wire run to wall switch is too long and/or has high resistance the thermopile may not be able to generate enough voltage to overcome the resistance. Check voltage at gas valve (will be in millivolts) and compare to spec for the gas valve. **Q: Is this appropriate for a 20 year old heat-n-glo model # sl-750-trs-c serial # sl 75trscn ?** A: Yes, that is what we have, my husband installed it and it works fine. **Q: Will this work with heat & glo sl 950- tr-ipi ?** A: It worked on a Heat N Glo AT Grand model, if it has a standing pilot you should be good. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality replacement part.! *by B***R on November 10, 2019* Great replacement part..!!
