Like an artist who can bring the beauty of nature to life, Real-Fyre artisans work from real wood samples to meticulously recreate the intricate bark detail and natural coloration of deeply charred wood. The Peterson Real Fyre 18-Inch Charred Royal English Oak Gas Log Set with Vented Propane Gas GX4 Burner - Manual Safety Pilot (CHB-18 - GX4-18-20P) includes individually hand painted refractory ceramic gas logs, glowing embers, vermiculite, burner stabilizing clips, flex connector kit, damper clamp, heavy duty custom grate, and propane gas GX4 burner. This burner system features a primary burner for great log presentation and the Ember Glow accentuates the ember bed of the log set for a realistic look. Also included is a low profile safety valve with standing pilot, for manual on/off control (SPK-26).
