Abstract: A flue collector box for a furnace having a cooling coil, a heat exchanger, and an inducer blower includes a housing having an interior chamber in fluid communication with the heat exchanger such that condensation generated in the heat exchanger flows to the interior chamber of the housing. A valve is connected to the housing and includes a pair of lips defining a fluid passage through the valve in fluid communication with the interior chamber. The lips have an open condition allowing condensation to exit the valve when the inducer blower is deactivated. The lips have a closed condition forcefully engaging one another when the inducer blower is activated to prevent condensation from exiting the valve.

Abstract: A flow control device for an appliance including a burner and a blower for delivering a pre-mixed mixture of air and gas to the burner includes a flange defining an opening through which the pre-mixed mixture of air and gas flows from an outlet of the blower to the burner. A damper plate is provided in the opening downstream of the blower for increasing a static pressure at the outlet of the blower during ignition of the burner.

Abstract: A fuel burner includes a tube extending from a first end to a second end and having an outer surface and an inner surface defining a central passage. The central passage is supplied at the first end with a mixture of air and combustible fuel pre-mixed upstream of the tube. The second end is closed by an end wall in a fluid-tight manner. The tube includes fluid directing structure for directing the pre-mixed mixture radially outward from the central passage to an exterior of the tube such that the pre-mixed mixture rotates radially about the central axis along the exterior of the tube.

Abstract: A fluid directing structure for a direct fired appliance having a heating space, a burner for providing heat to the heating space, and an exhaust includes a duct. The duct includes a first passage extending from a first end adjacent the burner to a second end fluidly connected to the exhaust. A second passage extends from a first end fluidly connected to the first passage to a second end fluidly connected to the heating space. A damper is connected to the duct and has a first condition directing fluid flow from the first end of the first passage to the second end of the first passage while preventing fluid flow to the second passage. The damper has a second condition directing fluid flow from the first end of the first passage to the second passage while preventing fluid flow to the second end of the first passage.
