    • A non-bypassable catalyst assisted appliance (100, 1000) comprises:
      a housing (112, 1112) having a combustion chamber (300, 1300), a loading door opening (117, 1117), an air inlet opening, and an exit opening; a platform (310) operably forming a top surface of the combustion chamber; a catalyst combustor (200, 1200) disposed above the combustion chamber, the catalytic combustor defining a single flow path and operable to support catalytic combustion for emission reduction; an automated secondary air control system (1500) for automatically regulating a flow of secondary air to the combustion chamber operable to support secondary combustion for emission reduction. When a loading door is closed, gas from the combustion chamber is directed along the single flow path through the catalyst combustor and out the exit opening; and when the loading door 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 gas from the combustion chamber are directed along the single flow path through the catalyst combustor and out the exit opening.
