If you're looking for sleek and ultra-modern fireplace, then look no further than the Rasmussen Indoor Alterna Vent-Free FireGlitter See-Thru Burner. It allows for the functionality of a traditional fireplace without the hassle of setting up and cleaning a ventilation system. While we do recommend keeping your glass door open for proper combustion, this fireplace burner doesn't need to be connected to a flue or other system, cutting down on installation time and cost.

Ideal for see-thru fireplaces, the steel chassis' double sided design ensures guests can enjoy the flames even from separate rooms. Designed for use with fire glass (sold separately), the Alterna features a unique opposed louver, lanced port burner that allows for a concentrated, efficient fire and complete combustion by designating the fire glass on the burner 'shroud' and leaving the actual burner free and clear of fire glass. Vent-free burners are typically used in approved vent-free fireplaces that do not have a designated ventilation system. Glass doors must be left wide open for proper ventilation, proper combustion, and cooling of safety control valves. Vent-free burners draw in air from your home and burn at a 99.99% combustion rate to allow for use indoors without ventilation. Although the Alterna Vent-Free burner system comes standard with a built-in manual control valve for easy operation, optional remote control upgrades are available. Regardless how you choose to customize the look of your fireplace, this vent-free burner system is certain to add an elegant, modern flair to your indoor living space.
