Description

The Damper Sealing Kit is designed to seal off your damper around your stainless steel chimney liner kit when installing a fireplace insert or a freestanding stove. Includes two galvanized metal sections which adjust to fit around the chimney liner. Also includes insulation and all hardware required to complete the job. Seals off dampers up to 48 inches wide. Flex connector/chimney liner not included. Click here for damper sealing kit instructions.

When you have a large opening around the liner, it allows the hot air, created by the insert or stove to rise up into the chimney up into the chimney chamber, which reduces the amount of heat that is intended for heating the house.

If you are removing your fireplace damper and have questions, check out our helpful article on what to expect.

Another great option is to use our smaller insulation blankets. These sections of insulated blankets can be cut, shaped and placed with the Sealing Kit or by themselves into the openings to prevent the loss of hot air, and increase the efficiency of your appliance. See our insulation page for insulation blanket only, pre-cut lengths.
