The new Real Fyre® G31 three-tiered gas-log system closely replicates the look and feel of a real wood-burning fire. This multilevel burner system provides a high, full flame effect with an efficient lower-Btu input. Offered in sizes ranging from 18 to 39 inches and at Btu levels of 55,000 to 85,000, the system features hand-detailed logs that look great in the fireplace—with the fire on or off. Many control and log-style options are available.
