The 304 stainless steel Real Fyre Vent-Free See-Thru Glass G21 Burner offers the perfect addition to any contemporary hearth. This vent-free burner has many installation options and can be placed in a variety of locations, such as an existing masonry hearth or within an island or peninsula setup. As 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 the installation process much easier.

One of its best features of this burner is that fire glass can be placed directly on top of the burner, as opposed to only surrounding it. This not only hides the burner, but also provides for a much fuller look. In addition, the G21 Glass Burner gives your fireplace added drama by allowing the flames to dance on top of the fire glass--casting glittering reflections in all directions. It features a polished metallic mirror finish , which reflects the glass, making your burner area seem larger. With your choice of striking metallic finish, this burner allows for complete customization to ensure a perfect fit with your existing decor.

With 99.9% fuel efficiency, your vent-free burner makes a great supplemental heat source for your indoor 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. The G21 burner is compatible with propane or natural gas, and comes complete with a pre-assembled remote 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--season after season.

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.
