Abstract
A burner pan comprises a large top plate conforming to the entire burner area for providing convenient support for the logs and wide flexibility in the configuration and location of the gas flame ports. The burner pan comprises a plurality of gas ports disposed along the outer periphery of the top plate, a burner plenum subjacently disposed along the outer periphery of the top plate for delivering gas to the gas ports, and a dead air space in the center of the burner pan. The burner plenum is formed between a shallow gas-tight outer housing shell which defines the outer peripheral walls of the burner plenum and a smaller inner shell adapted to fit within the outer shell which defines the inner peripheral walls of the burner plenum and circumscribes a substantially sealed central dead air space which is essentially free from the burner gas.
