The Damper Sealing Kit is designed to seal off your damper around your stainless steel liner when installing a fireplace insert or a freestanding stove.
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. It is very common to have to ovalize a short section of the liner in order to pass the liner through the throat damper. The Damper Sealing Kit can effectively seal around 6" thru 10" round liners that are ovalized to the minor dimension of 4". The Damper Sealing Kit will also work with 4" round liners.
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.

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.
