ABSTRACT:
A combustion air and exhaust gas balancing system for use with a direct-vent heater appliance. The balancing system includes a combustion air valve in fluid communication with a combustion air duct and an exhaust gas valve in fluid communication with an exhaust gas duct. The combustion air valve is operatively coupled to the exhaust gas valve with an actuator. The combustion air and exhaust gas valves are shaped and sized so that a single operation of the actuator simultaneously adjusts the flow of combustion air into the firebox and the flow of exhaust gas out of the firebox and provide selected flame characteristics in the firebox. In one aspect of this embodiment, a movement of the actuator in a first direction simultaneously increases the flow of combustion air and exhaust gas, and a movement of the actuator shaft in a second direction simultaneously restricts the flow of combustion air and exhaust gas. The actuator shaft is securable after final adjustment of the combustion air and exhaust gas flows to maintain the selected adjustment. In another embodiment, the exhaust gas duct includes a dilution air inlet aperture that permits combustion air to pass from the combustion air duct into the exhaust gas duct without first passing through the firebox.
