  • Work gloves
  • Safety glasses
  • Flat head screwdriver
  • Wire brush or electric drill with rotary wire brush bit
  • Gasket cement
  • Door gasket
  • Glass gasket (either rope or tadpole)
    • Please note that Fast Replacement Glass highly recommends replacing your glass and door gaskets regularly to keep you stove operating as efficiently as possible. When you are replacing your door's glass panel, this is a particularly ideal time to install new seals!

How to replace the ceramic glass in your wood stove.

  1. Remove you stove door and lay it on a flat surface that has been cushioned with cardboard, a soft drop cloth, or a blanket.
  2. Remove any screws or clips that are holding the glass in place; then carefully remove the pane and set aside.
  3. Using the flat head screwdriver, gently insert the head underneath the door gasket and lift up. Slowly and carefully pull the seal up and out, all the way around the channel.
  4. Repeat for the glass gasket.
  5. Clean out the grooves with a wire brush or an electric drill with a rotary brush bit. Make sure to wear safety glass to protect your eyes from any debris. 
  6. If they are not pre-measured, lay your door and glass gaskets against the channels and then cut to size. Make sure to leave about 1/4” - 1/2” extra gasket material on each end.
  7. Apply Wood Stove Gasket Cement around the entire door channel.
  8. Starting at the midline of the door, place the seal in the groove and push in firmly all the way around.
  9. Carefully remove the glass from the packaging and take off any labels.
  10. If using a rope gasket for the glass, repeat steps 7 and 8. If using a tadpole gasket for the glass, peel the adhesive backing from the seal and then firmly press onto the glass. Be sure to center the gasket over the edges of the glass pane so that when you adhere the material to the pane, it is “hugging” the glass all the way around.
  11. Gently place the glass pane into the desired position and replace clips or screws to secure it.It is very important that you only finger tighten screws and clips first. Then use a screwdriver to apply an extra half turn. Any more pressure than this and the glass could break.
  12. Allow the cement to cure according to the package directions before replacing your door and lighting a fire.
