Best Direct Vent Gas Fireplace Buying Guide

One way to categorize gas fireplaces is by whether they are vented or not. In that regard, we can classify fireplaces as either non-vented (also vent-free or vent-less) or vented. 

What is a Vented Gas Fireplace?

Essentially, vent-free models don’t drive the gaseous byproducts out. Instead, the gases are dispersed within the house, together with the generated heat. Since some of the byproducts of gas combustion aren’t safe for humans, direct vent fireplaces are designed for extremely high efficient burning. Some vent-free burners are as much as 99.99% efficient, meaning that combustion byproducts are negligible and rarely dangerous. 

Vented gas fireplaces are different. While also very efficient, they utilize various means to drive combustion gases outside the home. Usually, special pipes are used to guide the gases out, through the wall, roof, or the chimney.

Natural Vent vs. Direct Vent

Vented fireplaces are further divided into two subcategories – natural vent and direct vent. Natural vent models resemble conventional wood-burning fireplaces. Even the vent pipes are almost the same. The B-vent pipes used in natural vent fireplaces are, however, smaller than the A-class chimneys used in traditional wood stoves.  

Direct vent fireplaces are a lot more modern. First off, they implement what’s known as closed combustion, where the byproducts of the burning process are closed off from the room. Secondly, rather than use a single pipe (vent/chimney) to guide combustion gases out, they also introduce a second pipe to draw oxygen into the firebox. To ensure that no combustion gases escape, the fireplaces are sealed off with a glass door/panel that cannot be removed. 

The pipes used in direct vent fireplaces are much smaller in size compared those used in natural vent fireplaces. 

Advantages of Direct Vent Gas Fireplaces

Direct vent fireplaces have three main advantages over vented and natural vent models. These are;

  • Efficiency

Though not as efficient as open combustion, vent-free models (which can be up to 99% efficient), direct vent fireplaces are far more efficient than natural vent models. Most natural gas fireplaces garner efficiency ratings as high as 78%, meaning that up to 78% of the gas fuel is converted into usable heat. This is much higher than traditional fireplaces that are only about 30% efficient. Some direct-vent fireplaces are equipped with blower systems to help evenly distribute this heat throughout the intended area. 

  • Safety

Direct vent fireplaces are also much safer for home occupants. The gas-burning process produces multiple byproducts, including carbon dioxide, carbon monoxide, nitrogen dioxide, sulfur dioxide, water vapor, and various hydrocarbons. Some of these gases, such as carbon monoxide, are not safe for humans. Extended exposure to CO causes poisoning and can kill. Direct vent fireplaces have systems in place to drive out these harmful gases to ensure you and your family’s safety. 

  • Versatility 

The efficiency and safety advantages of direct vent fireplaces mean that the units fit a wider range of applications compared to vent-free and natural vent models. Natural gas fireplaces, for instance, use the oxygen within the home to fuel the burning process while direct-vent models draw the required oxygen from outside the house. As such, direct-vent models are a better fit when shopping for a bedroom fireplace. Vent-less fireplaces, by comparison, are highly regulated countrywide and forbidden completely in the bedroom. 

Factors to Consider When Choosing a Direct Vent Gas Fireplace

Direct vent fireplaces come in many designs, sizes, and styles. The following are a few vital considerations to help you pick the right one for your application.

  • Design

Standard one-sided models are the norm when shopping for a direct vent fireplace. But, there are also two-sided, three-sided, and even four-sided options to consider. The three-sided models are often called peninsulas, while four-sided designs are called islands. Aside from that, you also have bay-window shaped and corner units. 

  • Physical size

With regards to physical size, the options are endless. What you need to remember is that physical size takes into account the length, depth (width), and height of the unit. Lengths often range from about 30 to 48 inches, while depths (width) range from 24 to 30 inches. Depths tend to be in the 13 to 18 inches. It’s important to consider the space you have available before making a choice here.

  • Venting style

Most direct vent gas fireplace vent either through the top or rear. Rear-vented models work best when you intend to drill the pipes through the wall. However, if wall-venting isn’t a clear cut option, go with a top-venting model that vents through the roof. Depending on the model, the vents may run vertically or horizontally – up to 25 feet or more.

  • Log options

Direct vent gas fireplaces offer two main log types – ceramic fiber logs and refractory concrete logs. Ceramic fiber logs glow and have radiant properties for higher efficiency. They are also 75% lighter than refractory logs. Refractory logs, meanwhile, are more durable. The logs typically come in three sizes, i.e., 18, 24, and 30 inches. 

  • Features and Controls

Features and controls vary from one manufacturer to another. Some important ones to consider include;

  • Ignition type: Most gas fireplaces use pilot lights, electric sparks, piezoelectric, or manual (match) ignition. Which ignition type best suits your needs?
  • Thermostat: Thermostats are vital in controlling the amount of heat generated by the fireplace at any given time. The thermostat is, therefore, critical to achieving ideal comfort during heating.
  • Remote control: The main advantage of the remote control feature is that you don’t have to walk up to the fireplace to change the flame or heat settings. You can do that from the comfort of the sofa.
  • Speed fans: To speed up the heating process and distribute the heat more evenly throughout the room, you may want to also check for the presence of a variable-speed blower.


You’ll also need to consider the fuel type and installation method. Does the fireplace use propane, natural gas, or both? And, with respect to installation, is it an insert, built-in, or freestanding fireplace? Inserts install into an existing traditional fireplace, built-in models are recessed into the wall, while freestanding models stand on their own feet.

Direct Vent Gas Fireplace Safety

Even though direct vent fireplaces feature pipes designed to direct combustion gases outside the home, they still come with a few safety risks. These include;

  • Gas build-up: There have been reports of gas build up in the firebox if the pilot light isn’t lit or goes off unexpectedly. Lighting a fireplace with such gas build-up can cause a small explosion.
  • Excess heat: Direct vent fireplaces generate a great deal of heat. Even the protective safety glass and mesh at the front of the unit might get very hot during operation, which can cause burns when touched.

To prevent these and other possible safety hazards, the following safety precautions are recommended;

  • Check for safety certifications: The best gas fireplaces are approved or certified by at least one recognized safety authority, such as the American Gas Association (AGA). 
  • Check that it’s approved for the application: This applies if you intend to use the fireplace in the bedroom, mobile home, or at a relatively high elevation. Be sure that it’s approved for that usage.
  • Ensure proper installation: For peace of mind, it would be best to have a professional install the unit. It’s the only way to ensure that everything is done as required with no loopholes.
  • Be vigilant with kids and pets: Whenever the fireplace is running, you must be around to ensure that the kids or pets don’t get too close to the unit for the risk of getting burned. 
  • Ensure regular maintenance: Gas build-up and other safety risks can be averted through regular maintenance and scheduled inspections. At least once every three or four months, have a professional look at the unit to diagnose and fix any issues as well as fine-tune it. 


Direct vent fireplaces are popular among consumers and for a good reason. They are not only clean-burning but also very efficient and safe for use even in the bedroom. If you decide to buy one, make sure to choose the right design, size (physical), and venting type. Also, consider features such as thermostat control, ignition type, and remote control. Above all, make sure that the unit is safe for the intended application.
