What is a Vent Free System, you ask? So glad you did. We know in this industry there is a lot of lingo that isn’t used in your world so we want to help you understand your options and make the best choice for your home. Simply stated, a Vent Free System is a complete fireplace—a firebox (the metal shell), burner (where the gas goes) and log set (the pretty part we all ooh and aah over), with no venting or ducting required.

Just drop it into a decorative cabinet, hook it to your gas line and in about two hours, voila! you have a fireplace. It can’t be that simple, you think. Surely there is a catch. Nope, no catch—it really is that simple. For a home with no existing fireplace but with a gas line (or the ability to add one), it really is that easy. Systems can also be installed in a wall as well, if you prefer that look. That takes a little longer and requires a bit more effort, but a vent free system is still an ideal choice—no costly venting to run. A Monessen vent free system can be installed on an interior wall or below grade structures where a vented system would be expensive, or impossible, to install.

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. You then add the vent free log set of your choice to complete it.

Seem complicated? Why not just buy a system? A system is a great option to have everything you need all in one easy choice but sometimes you may not like the log or liner options that comes with a system. Some Monessen vent free systems give you the option of different log sets, but with a firebox, you can choose virtually any log set your heart desires. It’s like custom designing your own fireplace!
