This Damper Sealing Kit is designed to seal off your damper when installing a fireplace insert with a short pipe going up the chimney. Not NFPA (National Fire Protection Association) 211 compliant.

If you want to seal off the damper area and are using a full length stainless steel chimney liner, see our insulation page for insulation blanket only, pre-cut lengths.

Includes two galvanized metal sections which adjust to fit around the chimney liner. Seals off dampers up to 48 inches wide. Also includes insulation and all hardware required to complete the job. Flex connector/chimney liner not included. Click here for damper sealing kit instructions.
