Abstract
An improved inducer for a gas furnace having a housing and cover includes a number of radially extending tabs spaced around the inducer cover. Each of the tabs has an aperture formed therein. The inducer housing is provided with a number of flexible arms including a barbed detent at the distal end of each arm. The flexible arms are spaced around the outside of a side wall of the housing, fabricated from the same material as the housing, and correspond in number and placement to the tabs on the cover. A sealing channel with a gasket provided therein is formed on the interior side of the cover. The sealing channel corresponds in shape to the top edge of the housing side wall. When the channel gasket is placed in contact with the top edge of the wall and each respective barbed detent within a corresponding tab aperture, a force exerted against the housing and cover will cause the arms to bend slightly and the detents to snap into the tab aperture thereby securing the cover to the housing.
