Lost or broke the remote for your electric fireplace? This is a direct replacement infrared remote control, specifically designed for many Twin Star, ClassicFlame, and Duraflame fireplace and stove heater models. The model number is T-A8. It's NOT a universal remote, so it's made to work perfectly with a long list of units like the DFI-550-22, DFS-450-2, CFI-3108-06, DFS-550-11 through 14, and many more (check the full list in the description). The best part? It works right out of the box with no programming needed – just pop in the batteries and you're good to go. Speaking of batteries, it requires 2 AAA batteries (1.5V), which are not included. If you're not 100% sure this remote is compatible with your specific fireplace model, please contact us before you order to avoid any hassle. Get your cozy fireside convenience back!
