A gas fireplace log set is a great way to enjoy the look and feel of a wood burning fireplace without all the work. Vent free gas logs are easy to install and can be used in an existing wood burning fireplace or in a specially designed vent free firebox. Vent free gas logs burn cleaner than wood, producing less soot and airborne pollutants. They are also more energy efficient, providing more heat with less fuel. As with any type of fireplace, however, it is important to have your vent free gas log set installed by a qualified technician to ensure safety and optimal performance.
