I ordered it and they came and installed it. It worked great and simple to install. ### ⭐⭐⭐⭐⭐ Perfect match and perfect fit *by S***R on January 17, 2025* The pilot light would not stay lit on our fireplace and I determined it was either the thermal sensor or the valve assembly so I replaced both and it all works perfectly now, no issues. The home was built in 2009 so I decided the best course of action was to replace both these parts to make certain I would not have to tear into this fireplace insert more than the one time. I matched the part visually as I could not find a part number to reference and the fireplace insert we had was made in Canada and there were no matching parts on Amazon to match the manufacturer of this insert. Price was reasonable and delivery was on time. ### ⭐⭐⭐⭐⭐ One of the simplest joys in life is flipping a switch and having fire. This makes that possible. *by S***L on February 6, 2025* My fire place quit working. I put this in, and now it works again. Yay. ## Frequently Bought Together - 0820652 SIT 820 Nova mV Natural Gas Replacement Millivolt Gas Valve for Fireplaces, Stoves, and Gas Logs - Replacement OEM components for Direct Vent Appliances - 10002264 Pilot Assembly NG Fireplace Replacement of HHT Majestic & VC NG Pilot Assembly for Fireplaces, Fryer with 750mV Thermopile --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/560619734-0820652-sit-820-nova-mv-natural-gas-replacement-millivolt-gas](https://www.desertcart.tn/products/560619734-0820652-sit-820-nova-mv-natural-gas-replacement-millivolt-gas) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-03*
