With the addition of the HF-577IU3 Thoroughbred (left) and the HF-577IU7 Highlander (right) wood-burning inserts, Hi-Flame continues to offer new and innovative products to the U.S. market. The Thoroughbred model has a wide, decorative cast-iron surround and is only 25 inches high, allowing for easy installation. The taller Highlander insert, at 26 inches high (with a minimal surround) is ideal for custom insert installations. Both units will handle 24-inch–long wood.
