Harman Advance Hopper Lid Ceramic Glass Panel (18" x 7 1/2") is the exact OEM-style replacement designed to restore clarity, safety, and proper function to your pellet stove. Made from true high-temperature ceramic glass, this panel is built to handle extreme heat up to 1,400°F (760°C) without cracking or warping. It delivers clear, distortion-free visibility into the hopper while maintaining the solid, reliable performance Harman stoves are known for.
Unlike tempered glass (which should never be used in stoves), this Harman Advance ceramic glass replacement features the correct material, thickness, and fit—no trimming, no guesswork. Manufactured in the USA and matching Harman part number 3-40-06693, it installs cleanly into the hopper lid for a secure, dependable seal when paired with a tape gasket (sold separately). If your original glass is damaged, cloudy, or missing, this panel brings your stove back to safe, like-new condition.
