Linear fireplaces features a linear burner. This creates a single line of flame in a wide swath. This flame runs from one end of the unit to the other. This minimal flame and lack of a log set helps create a contemporary, clean look that features the flames not the accessories.
Linear fireplaces often use decorative fire glass, fire gems or stones to surround and hide their burners. These options can be customized with additional material or by using different colors. These stones and gems will accent the flame while disguising the burner and can be easily replace when they become dirty or out of style.
