Choose your options:



This 304 stainless steel G21 18" Glass Burner with On/Off Remoteoffers 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 as the wall or within an island. This is because the 18" vent-free gas fireplace inserts don’t require the venting associated with traditional fireplaces, allowing you more freedom to choose where to install your burner, as well as making installation much easier.

One of its best features 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 more fuller look. In addition to this, it also gives your fireplace some style by allowing the flames to dance on top of the fire glass. It features a polished mirrored finish backing, which reflects the glass, making your burner area seem larger. This burner allows for customization by giving you a choice between standard or gold trim. 

With 99.9% efficiency, your vent-free burner makes a great supplemental heat source. 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 both propane and natural gas, and comes complete with a pre-assembled remote control valve, as well as an On/Off Remote. Our G21 series glass burner is ANSI certified so you can feel confident with your purchase.

If you are in need of fire glass and feel you would like to match your home’s decor, view our Starfire Glass Collection. We offer many colors, shapes, and sizes for you to chose from.  If you would like a larger burner, you may upgrade to a 24" or 30" from the above drop-down menu.
