Spark Modern Fires. Instead of a firebox with opaque back and side surfaces, the Fire Ribbon is now available as a two- or three-sided see-through fireplace. The two-sided model embeds within a wall so the ribbon of flame can be enjoyed from adjoining rooms, such as a bedroom and bathroom or living room and kitchen. In a peninsula installation, a third visible side lets viewers enjoy the fire from multiple angles. 866.938.3846.

The B-vent style will appeal to environmentally conscious homeowners and those in areas where wood-burning fireplaces are prohibited. Choose from natural or propane gas models. 800.953.6669.
