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 36-Inch Charred Mountain Birch Gas Log Set with Vented Natural Gas G31 3-Tiered Burner - Match Light (CHMBW-36 - G31-33-39) includes individually hand painted refractory ceramic gas logs, a natural gas advanced three-tiered G31 burner with porcelainized reflective front pane, custom grate, bryte coals, glowing embers, sand, connector kit, and damper clamp. This burner features a 3-Tiered burner design for a high, full-bodied flame, with a compact footprint to fill your fireplace. The G31 has a porcelainized reflective front panel to provide a deeper ember bed reflection. This natural gas set features a match light system that uses your existing key valve and does not include a control valve.
