Abstract
A self-adjusting, telescoping concentric flue assembly provides non-separating, substantial flexibility between the telescoping sections of both the flue and the air supply ducts. The lower flue and air supply ducts may move radially independently of each other sufficiently to permit installation even on a furnace having somewhat non-concentric flue and air inlet connections. Attachment of the lower air supply duct to the furnace insures that the lower flue is likewise attached, yet the lower air supply duct can be raised independently of the lower flue to check the connection of the latter with the furnace flue connection.
