The 304 stainless steel Quick Ship Real Fyre Vent-Free Glass G21 Burner offers the perfect addition to any contemporary hearth. This vent-free burner has numerous installation options and can be placed in a variety of locations, such an existing masonry hearth or other ventless firebox applications. Because vent-free gas fireplace inserts don't require the venting associated with traditional fireplaces, they allow you more freedom to choose where to install your burner, as well as making installation much easier.

One of the most popular features of the Real Fyre Vent-Free Glass G21 Burner allows you to place fire glass directly on top of the burner, as opposed to traditional burners where fire glass is placed around the burner and cannot be placed on top. This not only hides the burner, but also provides a much fuller look. In addition to the visual effect of added depth, this glass burner also enhanced the look of your fire by allowing the flames to dance and reflect on top of the glittering fire glass. The G21 burner features a polished mirrored finish, which reflects the glass, making your burner area seem larger. Choose between various metallic trims for the ultimate in customization.

With 99.9% efficiency, your vent-free burner makes a great supplemental heat source in your indoor entertaining space. It comes with a built-in Oxygen Depletion Sensor that continuously monitors oxygen levels in the air of the room and turns off gas to the system well before oxygen is lowered to an unsafe level. It is compatible with propane or natural gas, and comes complete with a pre-assembled control valve, as well as a basic On/Off remote control. The G21 series glass burner is ANSI certified so you can feel confident with your purchase.

To learn more about the safety and installation of your burner, please read the informative owners' manual located in the Documents & Downloads. California residents, please note that vent-free fireplaces are not approved for use within the state.. Local codes may vary.

Designed for use in solid fuel-burning masonry fireplaces, UL-127 factory-built fireplaces certified for use with vent-free systems, and listed ventless firebox enclosures.
