ABSTRACT:
An apparatus is disclosed for use in venting the products of combustion from a power combustion system such as an induced draft furnace. The apparatus includes a housing having three openings and a baffle. One opening in the housing receives the gaseous products of combustion from the power combustion system. A second opening in the housing is connected to a flue pipe which directs the products of combustion from the housing to an outlet vent. The third opening in the housing has a spillage damper or movable panel which can cover the third opening. The panel is pivotally connected to the outside of the housing above the third opening. When the pressure within the housing is less than the surrounding atmospheric pressure the panel is forced closed by this pressure. The panel is forced open and the products of combustion in the housing are vented to the surrounding atmosphere when a pressure greater than the surrounding atmospheric pressure is present within the housing. The baffle is located within the housing near the first opening and directs flow through the housing from the first opening to the second opening.
