Abstract
An indoor smoker includes a smoking chamber and an air handler for drawing a flow of smoke from the smoking chamber through an exhaust duct. A catalytic converter is positioned in the exhaust duct and includes a catalytic element and catalytic heater for heating the catalytic element to a temperature suitable for regulating emissions from the flow of smoke. A temperature sensor is used to monitor the temperature of the catalytic element, and smoke generation is stopped when the catalyst temperature drops below a temperature threshold or drops at a rate that exceeds a threshold rate, which may be indicative of a failure of the catalyst heater or air handler.
