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 Mountain Birch Gas Log Set with ANSI Certified Vented Natural Gas G46 Burner - Manual Safety Pilot (CHMBW-18 - G46-18) includes individually hand painted refractory ceramic gas logs, a natural gas ANSI certified G46 burner with pre-assembled control valve & regulator, Piezo igniter, custom grate, glowing embers, sand, connector kit, log locators, & damper clamp. This patented system features hidden installed controls, piezo ignition, and lively flames and embers with fewer BTUs (fuel consumption). The Ember Glow creates a realistic look. Ignition is controlled by a low profile safety valve with standing pilot, for manual on/off operation. A double heat shield keeps the valve cooler.
