ABSTRACT:
A fuel economizer, for mounting in a flue pipe between a furnace and a chimney, having a lateral vane overlying a cutout in the flue pipe and carrying a baffle plate in between ends thereof mounted transversely to the flue pipe to obstruct a portion of the passageway therein. A housing overlies the vane. Hinge and weight means are attached to the vane and baffle plate to permit opening of the baffle plate, in response to gas pressure exerted on an interior surface of the vane, and closing down thereof, to maximize efficiency of the furnace by providing a properly sized flue outlet during different phases of use of the furnace.
