This energy-saving damper from Lyemance is built to fit 8 by 8 inch flues. Silicone rubber seals create an airtight barrier, keeping air inside and debris outside your chimney. The unit is easy to install and easy to operate, with a 32-foot durable stainless steel cable included that mounts in the firebox for simple access. The manufacturer provides a lifetime warranty, but also notes that use with gas logs is not recommended due to the possibility of carbon monoxide buildup.
