If your wood stove glass has cracked, you’ll need to replace the glass for both safety reasons and unit efficiency.  When you replace wood stove glass, you’ll need to make sure you are ordering the correct type of glass. Wood stove glass is not actually glass, but a transparent ceramic (NeoCeram, Pyrex) created to withstand the extreme temperatures created inside a wood stove. 

How to Replace Wood Stove Glass

Always work on a Cool Stove

1. Prepare the area around your wood stove by covering the flooring with a tarp, plastic or lots of newspaper.
2. Clean the wood stove door, and if possible, remove and place face down on your covered flat working surface.
3. Remove the glass from the door, use a lubricant (WD-40 or PB-Blaster) to remove and residue or rust.
4. Loosening the screws slowly and take care not to strip them. If you are having trouble figuring out how to remove the glass, consult your owner’s manual.
5. If your gasket is getting older, this is a great time to replace it. Remove the rope gasket from the door and replace it with a new one.
6. Set the new ceramic glass into the door and very carefully tighten the screws. DO NOT OVER-TIGHTEN. Tightening the screws too much can damage the ceramic glass. It will need some room to expand when exposed to extreme heat, and tightening the screws too much can crack the glass.
