Most wood stoves have a gasket that will sometimes need to be replaced. Often this is a "rope" type gasket. I would advise either going to a good woodstove supplier near you, or even better an outlet that sells the specific brand of woodstove you have. Generally you will need to use some special adhesive to affix the gasket to the metal on the stove door, and the dealer can sell you that.
