Monessen GCUF GRUF Series Vent Free Gas Firebox GRUF42C-R

These vent free fireboxes create a realistic, built-in look, thanks to zero-clearance design. With three different sizes and two firebrick options, you can find just the right accent for your room decor.

Enjoy The Fireplace You've Always Wanted

Monessen offers one of the most diverse lineups of gas vent free fireplaces available, making it easy to find the right look for your home. Enjoy beautiful flames, excellent heating and a customized look, and many added benefits.

Create a Custom Look

The GRUF/GCUF series fireboxes provide the option to choose a louvered design or a radiant, clean face design. Choose from a selection of firebrick options and accessories for a fireplace perfectly suited to the design you prefer.

Save Energy And Maximize Heat

Vent free gas fireplaces (available in natural gas and propane) are a safe, green 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.

Install It Where You Want It

Because vent free fireplaces 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 to install a vented fireplace. They provide the most economical installation, only requiring a connection to a gas line.

Create Your Own Look

With multiple facing and firebrick options available, you can tailor the look of the fireplace to suit your tastes and décor.

You're In The Clear

Monessen vent free fireplaces 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.

Complete Your Look

Monessen offers a selection of vent free log sets (sold separately) that are a perfect complement to your new fireplace. Ask your dealer for details.
