The Enervex MFD-S Manual Fireplace Damper is designed to prevent excess heat loss and stop backdrafts in solid-fuel fireplaces when they are not in use. Installed at the chimney top, this manually operated, gravity-activated damper provides an effective way to improve energy efficiency and indoor comfort.
Engineered for round chimneys, the MFD-S can be used as a replacement for worn-out zero-clearance fireplace dampers and is fully compatible with or without an Enervex chimney fan. Its simple pull-chain and handle operation makes it easy to use without requiring any power source.
Built for long-lasting performance, the MFD-S is rated for temperatures up to 1400°F (760°C) and fits most standard round chimneys, making it a versatile and practical solution for wood-burning fireplaces.
