Monessen Hearth ACUF42-BD 42″ Attribute Universal Circulating Vent Free Firebox w/Brown Reversible Interior Panels

With a big presence and Monessen’s angled design that pushes out more heat, the Attribute ACUF42 vent-free firebox delivers a fireside experience with style. Choose trendy gray or classic brown interior panels—both available as a reversible panel for a traditional stacked brick or herringbone option—or go modern with reflective black glass for a subtle sophisticated twist. Finish your fireplace right up to the firebox with the material of your choice and add the Monessen log set you love for a perfect custom look.

Quick Look:

  • Deep box and wide opening provide generous room for the log set of your choice
  • Clean, louver less design
  • Screens tuck away into hidden pockets to reveal expansive views
  • Multiple reversible interior panel options (traditional stacked brick on one side & herringbone on the other) fit your décor and highlight your vent-free log set
  • A choice of add-on options creates your own unique look
  • Available in 32“, 36″ or 42″ models
  • Angled firebox and uniquely engineered air channels move more heat into the room, maximizing efficiency

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. Enjoy beautiful flames, excellent heating and a customized look with the addition of your choice of 24″ or 30″ Vent Free Monessen log sets.


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 fireplace (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 burner) of your choice to complete it.


  • Circulating firebox with radiant clean face and expansive viewing area
  • Features mesh screens with hide-away pockets, hood and junction box
  • Monessen exclusive two-piece hearth for easy access without removing log set
  • Proprietary Reversible Interior Panels standard, 2 aesthetics on 1 panel
  • Black hood
  • UL Listed
  • True masonry look
  • Viewing Area: 42″ W x 27″ H
  • Framing: 48-1/2″ W x 34-1/4″ H x 19-3/4″ D
