Combined with a Monessen vent free log set (sold separately), the Exacta firebox provides warmth and ambiance to practically anyone, anywhere.

Monessen offers one of the most diverse lineups of vent free gas fireboxes available, making it easy to find the right look for your home. With the addition of a Monessen vent free log set, you can enjoy beautiful flames, excellent, cost-efficient heating and a customized look, all without the hassle of extensive renovations or costly remodels.


A Monessen vent free firebox is the perfect way to display and operate your Monessen vent free log set. While our log sets can be utilized in an existing approved wood burning fireplaces (converted with a gas line), if your home does not already have an existing fireplace, a vent free firebox is an economical way to add a fireplace to your home.

Installed in either your wall or a free-standing cabinet, a vent free firebox is simply the metal combustion chamber of a traditional fireplace system, without the log set and engine. You then add the vent free log set (with engine) of your choice to complete it. By contrast, a vent free fireplace system includes the firebox, log set and engine as a package. It too can be installed either in a wall or a free-standing cabinet.

In either situation, since no venting is required, installation is faster and easier than with a traditional vented system.


Monessen offers a wide selection of Vent Free Log Sets (sold separately) that are a perfect complement to your new firebox.

  • No chimney or venting required makes installation fast, easy, and affordable
  • Clean, louver-less design
  • Tuck the screen into hideaway pockets to reveal expansive views
  • Black interior provides elegant background for vent free log set
  • Brick interior available for a traditional look
  • Large hearth area allows for a variety of log sets
  • Angled firebox and uniquely engineered air channels move more heat into the room, maximizing efficiency
  • Available in 36″ or 42″ models
