The Superior TM-4500 by Lennox Hearth Products is a clean-face wood-burning fireplace with a large 45-inch-by-29-inch opening. The unit has a brick-patterned interior, a zero-clearance design, and optional bifold glass doors. Tobler Duncker used it for this project “to eliminate the need for costly masonry construction,” Duncker says, and “to create an elegant modern look.” Lennox Hearth Products, 714.921.6100; www.lennoxhearthproducts.com.
