Vent Free Fireboxes
VERSATILE SOLUTIONS FOR YOUR HOME
ENJOY THE FIREPLACE YOU'VE ALWAYS WANTED
Exacta BUF Series
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 Monessen log sets.
WHAT IS A VENT FREE FIREBOX?
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
engine) of your choice to complete it.
INSTALL IT WHERE YOU WANT IT
Because vent free fireboxes and log sets are designed to be
installed and operated without a chimney, flue or vent, they
can be installed in locations in your home where it would

be impossible or cost prohibitive to install a vented fireplace.
They provide the most economical installation, only requiring a
connection to a gas line.
YOU’RE IN THE CLEAR
Monessen vent free fireboxes allow for zero clearance
installation, which means they may be installed flush against
any combustible surface such as drywall or wood. This gives
you added flexibility and helps save installation dollars when
deciding where to install your fireplace, whether on an interior
or exterior wall. (It is important to remember that the appliance
should be sized to fit the area in which it is to be installed and
must meet any additional regional or local requirements.)
COMPLETE YOUR LOOK
Monessen offers a large selection of vent free log sets (sold
separately) that are a perfect complement to your new fireplace.
Ask your dealer for details, or visit monessenhearth.com.
