The GlowFire 18" Arizona Weathered Oak Charred Log Set is designed to give the look and feel of the log being on fire. Each log is individually orificed and ported allowing the fuel to flow out of the log for the most realistic gas log set on the market. GlowFire log technology also allows for increased efficiency by using less BTU's and creating a fuller more robust flame effect. The ceramic refractory logs radiate more heat out into the room compared to traditional log sets. This set includes the logs only.
