Abstract
A gas burner system including a burner body having a flange providing an annular surface. A removable cap is disposed above the burner body and contacts the annular surface for forming an annular interface with the burner body for closing the burner body. A plurality of ports are provided along the annular interface between the burner body and the cap. A first ignitor is disposed adjacent the annular interface between the burner body and cap. A second ignitor is also disposed adjacent the annular interface between the burned body and cap. Electronic means energize the first and second ignitors for generating sparks to ignite the gas burner. The energizing means include means for sensing the presence of flame at both the first and second ignitors such that during burner operation, if no flame is sensed at both the first and second ignitors, the ignitors are energized for generating sparks.
