Abstract (en)
An apparatus for detecting the presence of a burner flame of a gas appliance includes a detection element for optically detecting the burner flame. The detection element is positioned adjacent to a location of the burner flame. The apparatus additionally includes a display element positioned remotely from the detection element. The display element is operative in a first mode to indicate the presence of a burner flame and a second mode to indicate the absence of a burner flame. The apparatus further includes a transmission element connecting the detection element and the display element. The transmission element causes the display element to operate in the first mode when the detection element optically detects the burner flame. <IMAGE>
