What is a Gas Insert?

Direct Vent Gas Inserts

Direct Vent Gas Inserts are complete fireplace units that slide into an existing masonry or prefabricated factory built fireplace. These inserts typically feature valve systems for simple ignition, remote controls, blowers, interior lighting, sealed ceramic glass windows and variable flame/ heat controls. Inserts also have several options to choose from. Including, decorative face plates, logs styles, and backgrounds.

The major benefit of direct vent gas inserts is the fact that the insert will pull outside air through a pipe lining the chimney and then exhausting outside through a second pipe in the chimney. The insert does not take any air from the home, it only provides heat.

Whereas, traditional open fireplaces can have efficiency ratings as low as 15% and can actually draw the heat from your furnace right out of your home, gas inserts can achieve efficiency ratings as high as 86%.

Direct vent inserts are the only true “inserts” in the fireplace industry. However, vent free gas logs and vented gas logs are also often called inserts.

Manufacturers of direct vent gas inserts include: Ambiance Fireplace, Fireplace Xtrordinair and Napoleon.

Vent-Free Gas Logssaratoga vent free gas logs american hearth

A vent-free gas log system uses room air for combustion and delivers 99.9% of the available heat energy directly to the room. Vent-Free systems have an unmatched safety record, thanks in part to their clean-burning technology and their Oxygen Depletion Sensor, which instantly shuts off the valve if oxygen in the room drops to an unsafe level. Vent Free logs can be installed into a UL listed and approved vent free rated fireplace or in a fully functioning masonry fireplace or in some factory built prefabricated fireplaces, according to the manufacturers directions.

Vent-Free systems are limited to 40,000 Btu and must be operated as supplemental heating sources in conjunction with a central furnace that circulates air. Vent-free log sets are not designed to burn as a sole heat source.

Advantages of Vent Free Logs:

  • Unmatched efficiency – 99.9%
  • Offers the most installation versatility
  • Usually less expensive to buy and to install
  • Can operate with a remote or thermostat

Vented gas logs are the ideal product for people who are looking for the most realistic looking fire without the mess and hassle of burning wood. Vented gas logs are more realistic looking than vent free gas logs but are much less efficient. A majority of the heat vented gas logs product will go up the chimney similar to burning wood in an open fireplace.

Log placement is more flexible with vented gas logs where vent-free logs must be set up according to the manufacturer’s specific directions.

A second type of vented gas logs are Radiant Vented Gas Logs. Radiant vented gas logs provide the same realistic flame pattern as standard vented gas logs, but provide as much heat as vent-free gas logs into your home.
