Abstract
A gas burner includes a base with a first body and a raised annular band on an upper surface of the first body. A flange is formed about an outer periphery of the first body wherein the raised annular band and the flange define a first annular recess therebetween. A first notch is formed in a lower surface of the first body and extends through the flange and communicates with the first annular recess. The first notch is adapted to accommodate spark ignitor therein. A slot is formed in the raised annular band. A first cap includes a peripheral side wall having a distal end dimensioned to be received within the first annular recess. A gap between the distal end and a bottom wall of the first annular recess when the first cap is received therein provides fluid communication between the slot and the first notch.
