Abstract:

A gas fired appliance measures infrared emissions from a metal object heated in a combustion chamber to evaluate combustion. Associated circuitry uses the evaluation to control operational parameters of the appliance, including fuel and air fed to the appliance. A second metal object, prior to fuel ignition, is electrically heated to emit infrared radiation. Infrared emissions from the second metal object, indicative of the temperature thereof, are monitored to assure an ignition temperature to ignite a combustible air and fuel mixture. A fan directs a stream of ambient air upon the second metal object to cool the same and reduce the infrared emanating therefrom. The reduction in infrared from the second metal object is monitored to verify proper fan operation.
