Abstract
An ignition device for burners in which an ignition spark is established over a nonconducting surface between a hot electrode and a grounded electrode or electrically conductor portion which enables a greater spark distance to be obtained as compared to an ignition spark which jumps across an air gap between two conducting electrodes. An additional feature of the present invention is the provision of a high limit control positioned proximal the burner such that flame resulting from heater inlet blockage will flash upstream into the vicinity of the high limit control to control operation of the burner.
