There are two types of door gaskets – a door jamb gasket and a main body gasket. The door jamb gasket is the strip of rubber or metal that seals the space between the stove’s door and the frame. The main body gasket is located on the inside of the stove and it seals the opening of the firebox. If you need new door jamb gasket or main body, check your stove’s user manual for specific guidelines on how to replace them and what type is needed for optimal performance.
