Each gasket kit includes a tube of high-temperature RTV silicone sealant for installation.

Clean the gasket channel thoroughly using a scraper and mineral spirits or denatured alcohol to remove any old adhesive or residue.
-
Stretch out the new gasket to make sure it lays evenly without twists.

Apply a continuous bead of high-temperature RTV silicone sealant around the track.

Proper gasket replacement helps maintain your stove’s efficiency, safety, and airtight performance. Check your stove’s manual for model details and recommended replacement intervals.
Note: These braided fiberglass gaskets can be gently stretched or compressed during installation for a more precise fit. Due to the natural flexibility of the material and changes in atmospheric conditions, gasket lengths may vary by approximately ±2–3 inches.
