Patent ID: 11287135

Abstract:
A non-bypassable catalyst assisted appliance includes, for example, a housing having a combustion chamber, a loading door, an air inlet opening, and an exit opening connectable to a flue. A platform defines a non-movable separation in the housing between the combustion chamber and the exit opening. An insulated catalyst combustor is disposed between a top wall of the housing and the platform. When the door of the appliance is closed, gas from the combustion chamber is exhausted and directed along a single flow path horizontally through the insulated catalytic combustor and into the flue. When the door of the appliance is open, gas from the combustion chamber is inhibited from passing through the loading door opening, and ambient air entering the loading door opening and combustion gas from the combustion chamber are exhausted and directed along a single flow path horizontally through the insulated catalytic combustor and into the flue.
