What Are Zero-Clearance Gas Fireplaces?

Zero-clearance gas fireplaces are specially designed to be installed directly against combustible materials with zero clearance from the unit to the framing. This makes them ideal for installation in tight spaces or areas where a traditional fireplace would not be possible.


Zero-clearance gas fireplaces come in a variety of styles and designs to suit any home decor. They can be freestanding or built-in, and many models offer a variety of features such as remote control operation, programmable timers, and decorative glass surrounds.

The biggest advantage of zero-clearance gas fireplaces is their flexibility in installation. They can be installed almost anywhere in your home, including against exterior walls and in corners. This makes them ideal for homes with limited space or unique layout challenges.

Another advantage of zero-clearance gas fireplaces is that they tend to be more energy-efficient than traditional wood-burning fireplaces. This is due to the fact that they are sealed tightly against the framing and don’t allow heat to escape up the chimney.

If you’re considering a zero-clearance gas fireplace for your home, there are a few things to keep in mind. First, make sure that the model you choose is approved for installation in your specific type of home (i.e., manufactured homes require a different type of unit than stick-built homes). Second, always hire a professional contractor to handle the installation – this is not a DIY project.

Benefits of a Zero-Clearance Gas Fireplace

When it comes to gas fireplaces, there are many benefits that come along with opting for a zero-clearance model. For starters, these fireplaces are much easier to install than their traditional counterparts. In addition, they are also much more efficient in terms of energy usage, which can lead to significant savings on your heating bills.


Another key advantage of zero-clearance gas fireplaces is that they do not require a chimney. This means that you can install them in any room in your home, regardless of whether or not there is an existing chimney. Additionally, because they do not produce any smoke, they are much safer to use than traditional fireplaces.

Different Types of Zero-Clearance Gas Fireplaces

There are three main types of zero-clearance gas fireplaces: direct vent, natural vent, and B-vent.

Direct vent fireplaces draw their combustion air from outside the home and exhaust directly to the outside as well, making them the most efficient and safest type of gas fireplace.

Natural vent fireplaces use the room’s air for combustion and typically have a glass front. B-vent fireplaces are similar to natural vent fireplaces, but they use a different type of flue system.

How to Install a Zero-Clearance Gas Fireplace

A zero-clearance gas fireplace is a great way to add a touch of elegance to your home. They are easy to install and can be placed in any room you desire. Here are a few tips on how to install a zero-clearance gas fireplace:

2. Cut out the opening for the fireplace using a saw. Make sure that the opening is big enough to accommodate the size of the fireplace you have chosen.
3. Install the firestop according to the manufacturer's instructions. The firestop is what will prevent fires from spreading through your home in the event of an accidental fire.
4. Install the lintel above the opening you have cut out. This will support the weight of the fireplace when it is installed.

  • If you are installing a prefabricated unit, follow the instructions that come with it. These units are usually easier to install than traditional fireplaces.
  • If you are installing a traditional masonry fireplace, first build a wooden frame around the opening you have cut out. This will provide support for the bricks that you will use to build thefireplace itself.
  • For prefabricated units, set the unit in place and follow all manufacturer's instructions for installation and safety precautions..
  • For masonry fireplaces
