This 12-inch round flat burner pan is designed to be permanently fitted into a circular fire pit. This burner pan greatly reduces the amount of fire glass you will need to fill your fire pit because it gives the pit a false bottom, creating the illusion that the fire pit is full whereas only the top portion of it is. Also included is a 6-inch ring burner so there is no need to buy any additional parts. The 6-inch Fire Ring is rated for 88,000 BTUs and is made from durable 304 stainless steel. This high quality 6-inch fire pit ring burner is designed to delight all onlookers with its amazing evenly-distributed flame. Furthermore, the burner holes have been drilled, not punched, which means no whistling noises are produced. This burner also comes with a convenient 1/2-inch gas inlet for easy connection to a natural or propane gas supply. Note: Must use propane air mixer to convert to liquid propane.
