The heartland oak vented log set by duluth forge recreates the look and feel of a real wood-burning hearth. This vented gas log set was molded from real wood providing a realistic appearance that incorporates charring, deep bark texture and split accents. The u- burner chassis design provides multiple rows of flames which brings you the most realistic flame patterns. Like a real wood burning fireplace, the heartland oak requires a fully functional chimney with an open flue when in use. The glowing embers create the most illuminating beauty of a warm and classical ambiance.
