Enervex 8" MFD-S for RSHT 009 and RSHT 012, 304SS

Manual Fireplace Dampers for Solid Fuel (used with FSC or EFC211). The MFD-S Manual Fireplace Damper for solid fuel prevents excess heat from escaping through the chimney when the fireplace is not in use and prevents backdraft down the chimney. It is designed for chimney top installations. The MFD-S is a manually operated and gravity activated fireplace damper for round chimneys. Although it is designed to support and function with an ENERVEX chimney fan, it works equally well without it. It can be used as a replacement for worn-out, zero clearance fireplace dampers. The damper is operated with a pull chain and handle (included) mounted in the fireplace. The MFD-S is designed for chimney top installations and is rated for temperatures up to 1400°F (760°C). The MFD-S Manual Fireplace Damper for solid fuel prevents conditioned air from escaping through the chimney when the fireplace is not in use, and to prevent backdraft down the chimney, saving energy.
