ENJOY THE FIREPLACE YOU’VE ALWAYS WANTED

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.

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 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.

FLEXIBLE INSTALLATION OPTIONS

Our extensive and versatile line of vent free fireboxes offer a zero clearance design which means installation is faster, easier and more affordable than other vent free fireboxes. They may be installed flush against any combustible surface such as drywall or wood, inside a cabinet, or installed in the wall like a traditional fireplace, and can be placed in locations where it would be costly or even impossible to install a vented product. This gives you added flexibility and helps save installation dollars when deciding where to locate your new firebox, whether on an interior or exterior wall. With a variety of sizes, styles and price points from which to choose, there is a Monessen vent free firebox to fit just about any space, style and budget. (Remember to always follow manufacturer’s installation instructions when considering the location and surroundings for your new fireplace.)

SAVE ENERGY AND MAXIMIZE HEAT

With the addition of a Monessen vent free gas log set, Monessen vent free fireboxes are a safe and energy efficient way to add heat to your home — in fact, they’re 99.9% energy efficient. Because they are vent free, none of the heat gets lost up a vent, flue or chimney. Instead, fuel dollars get transformed into heat-warming energy. Plus, you can always be assured of a heat source, even in the event of a power outage.

COMPLETE YOUR LOOK

Monessen offers a wide selection of vent free log sets (sold separately) that are a perfect complement to your new firebox. Ask your dealer for more information on choosing the right size and style for your space.
