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.


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


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 of all fireplace installations, only requiring a connection to a gas line.


Majestic 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.


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