17" x 17" Lyemance Energy-Saving Damper

Traditional dampers are located in the "throat" of a fireplace. They are made of cast-iron and are housed in a low-tech frame work. These cast-iron dampers do not seal well—they have a leaky, rough, metal-to-metal seal. Recent lab studies have shown that even a new throat damper can leak up to $200 of heating and cooling a year. Imagine how much energy an old, rusted out damper leaks!

Lyemance Energy Saving Dampers seal tightly to save you money. Lyemance's rubber gasket seals tightly like a storm door for your fireplace, and keeps heating and cooling dollars where they should your home. Lyemance mounts on top of your chimney to keep out animals and rain, and easily operates from inside your firebox, sealing tight every time you close it—eliminating any draft.


  • Easily mounts atop a flue tile
  • Silicone Rubber Seals Tight
  • Cast-Aluminum Construction
  • 32' Cable Included
  • Easy opening with power lever assist.
  • Lifetime Warranty


  • Size: 17" x 17"
  • Fits Inside Flue Sizes: 15" x 15" to 17-1/2" x 17-1/2"

Gas appliance warning: Don't use top-sealing dampers with gas logs. If the fireplace is converted to use as a gas appliance such as gas logs, this damper should be removed.
