Your Rushmore gas insert has great flames, but the firebox can look dull or unfinished without the right liner. A plain or outdated interior absorbs light and makes the flames look smaller. Even a premium insert can lose its visual impact if the firebox doesn't add depth or reflect the fire properly. Empire Liners for Rushmore Direct Vent Inserts boost flame brightness and improve the overall look of your firebox. Choose from classic brick, black porcelain, or reflective finishes to add depth and give your fireplace a clean, polished appearance. Each liner is custom-fit for Rushmore inserts and installs smoothly for an instant upgrade. Enhance your Rushmore insert with a liner that brightens, deepens, and completes your firebox.
