The Monessen GRUF Series Vent-Free Firebox is a radiant firebox that comes ready for installation. The firebox itself is identical to the GCUF series. What makes the GRUF different is a 2-in-1, flexible-face system that makes it a radiant system. Firebox available in widths of 32", 36", and 42". No venting means less expense and easier installation than a vented firebox.
