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 42-Inch Charred Mountain Birch Gas Log Set with Vented Natural Gas G4 Burner - Match Light (CHMBW-42 - G4-42) includes individually hand painted refractory ceramic gas logs, glowing embers, sand, burner stabilizing clips, flex connector kit, damper clamp, custom grate, and natural gas match light G4 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. This natural gas set features a match light system that uses your existing key valve and does not include a control valve.
