What is a Direct Gas Fireplace Insert?

Direct Vent gas fireplace inserts are among the most popular heating solutions, due to their efficiency and straightforward installation process. “Direct Vent” refers to the sealed-combustion of their design, through which air required for the combustion process e.g. creation of a fire is sourced from the outside of your home via the piping system. This is important to be aware of, since many consumers think “direct vent” simply means that all gases produced via combustion are vented out.

There are two major components of a direct vent fireplace, which are the outer housing and the flue system. The outer housing features the firebox where the actual combustion takes place and the fire can be viewed, therefore, this is the space in which the fuel, typically gas is burned. However, as many homeowners prefer the natural look of a fire, imitation logs or charcoal is used to provide a rustic, old-wordily fireplace feel. In addition to the firebox, there is an outer shell, referred to as the empty space, which is filled with air that is used to heat the room without the addition of toxic exhaust fumes from combustion.

The outer and inner flue system is another crucial component of the direct vent system. The outer flue transports air to the lower portion of the firebox to power combustion, while the inner flue transports hot exhaust gases from the upper portion of the firebox out through the wall or up through the roof of your home.

  2. When installing your gas fireplace, make sure to use only the parts that came with the unit. If an accessory is missing, then you have to contact the manufacturer or the store where you bought it from immediately to report the issue. Do not use an alternative part that you got somewhere else as it may not work well with the unit and eventually damage it. Doing it may also cause fire or other untoward situation. This is the last thing that you want to happen so make sure to follow this reminder strictly.
  3. No matter how familiar you are with the installation process, always refer to the instructions or the manual that came with the unit. Follow it carefully for proper installation.
