ABSTRACT:
A gas-fired burner including a cylindrical burner housing having a premixed fuel/air opening. Disposed within the cylindrical burner housing is a cylindrical burner ring which forms at least one row of a plurality of burner ports. The cylindrical burner ring is sized relative to the burner housing such that an annular space is formed between the burner housing and the burner ring. Upper and lower annular rings extend between the burner ring and the burner housing, thereby enclosing the annular space. Disposed within the burner ring is a secondary air flow restrictor for controlling the flow of secondary air to the flame. A multi-finger grate having alternating long and short fingers is disposed above the burner housing.
