Replacement Pellet Stove Exhaust Blower Gasket. Fits many models (Lennox, Breckwell, Enviro, & More). This gasket seals between the exhaust blower housing and the unit. It is important to inspect this seal periodically to make sure it is in good shape. If the gasket shows signs of deterioration or you notice stains on the gasket it should be replaced! Running your stove with a bad gasket may allow smoke to enter the room.
Note: Housing side 4-7/8″ ID
