ABSTRACT:
A gas smooth top range in which the burner beneath the glass ceramic top is of powdered blue flame, rather than radiant, type. The burner in this and other possible environments is controlled by electric circuit means including a resistance igniter element having an appreciable energy output, electrically operated valve means in circuit with the igniter, and cycle control means for cyclically energizing the igniter and valve means at a rate that can be varied to regulate the heat output of the burner. Heat transfer structure is associated with the burner and arranged so that hot exhaust gases from the burner are effective to preheat the respective inflows of ambient air and fuel making up the mixture which is combusted. The fuel valve can be adjusted from the exterior while operating in closed and sealed condition, or a simulation of such condition, so that the proper circuit relationship of the valve and the igniter with which it is used can be set as a manufacturing procedure to eliminate need for field or installation adjustment.
