Abstract
A special regulating type of transformer is used to energize a hot surface igniter, a fuel valve and a fuse in a series circuit. The design of the regulating transformer is such as to provide an operating current in the igniter and valve that will not blow the fuse as long as the igniter is neither short-circuited, nor heated to a level which would be destructive.
