Configurable low profile gas fireplace burner

Abstract

A gas fireplace has a set of artificial logs. The logs rest on top of a burner. The burner is formed from top and bottom metal sheets. The sheets are sealed together around a channel matched generally to the prospective position of the logs. A gas orifice feeds gas into the channel, while gas ports in the top sheet release the gas. The gas ports are positioned to match the final position of the logs. The channel is formed by creating a depression in the bottom sheet using a press with a general purpose stamping die moving in the pattern of the channel, or a single hit special purpose die, or a rolling die moving in the pattern of the channel, or by the bottom sheet being moved across a stationary rolling or beading die in the pattern of the channel. Secondary air holes feed air through the burner adjacent to the channel and the gas ports. The burner has a low profile, is manufacturable using conventional sheet metal techniques, and the ports, channel and holes may be redesigned for different fireplace characteristics. The logs may be replaced by or used in combination with other decorative fire material such as artificial coal or simulated embers. One or more recesses may be formed in the top sheet into the channel for recessing at least those gas ports that would be visible through the log set and for receiving alternate decorative fire material for hiding the ports.
