      For a sleek, compact burner with a 99.99% combustion rate, look no further than the 20" Alterna Vent-Free Stainless Steel Fireplace Burner from Starfire Direct. Its vent-free capabilities allow for installation in the home without having to vent out fumes and smoke like a traditional fireplace.

      This 20" vent-free fireplace burner provides 30,000 BTU of heat through the use of a built-in manual control valve, though remote controls are available for an additional cost. Similarly, you can choose a natural gas or liquid propane fuel connection type, so be sure to order correctly.

      What makes the 20" vent-free fireplace burner even more special is that it was created specifically for use with fire glass. Its unique design isolates the actual burner mechanism from the fire glass pieces so that there's no complications when creating the display you want.

      Available in many colors, shapes, and sizes, Starfire Direct's fire glass doesn't pop or crack. They enhance and reflect the light of the flames, creating an even more beautiful display. They also help distribute heat more evenly when compared to other types of burner media. 20" vent-free gas fireplace inserts from the Alterna line can hold seven pounds of fire glass. Feel free to mix and match colors and styles to your liking, as long as you don't overload the burner shroud. Many customers will also place fire glass around the base of the burner for an even more dazzling look. Explore your options today with Starfire Direct.
