Determine What Type of Gas Logs You Need

Do you want a realistic looking, wood fire substitute? Are you more interested in the most efficient way to heat your home? Here are some facts that should help you choose between a vented or vent free gas log set.

Vented Gas Logs

  • These logs must be installed in a fireplace with a fully functional chimney, to draft the smoke and combustion gases from your home.
  • These log sets have been available for over 50 years and are still the most popular.
  • Vented logs are the logs that most resemble a realistic wood fire.
  • They use an open damper, which limits heating efficiency. Just like burning a wood fire, most heat escapes the chimney and only a small amount is returned to your home.
  • Vented log sets are more flexible. Logs can be repositioned according to preference.

Vent-Free Gas Logs (Non-Vented)

  • Vent Free (also known as non-vented, unvented or ventless) logs do not require a chimney.
  • They keep 99 percent of the heat produced in your home, and are very efficient as a primary heat source.
  • All units are equipped with an ODS (Oxygen Depletion Sensor). This device cuts the flame off if the oxygen level in the air drops below a safe level. This situation is very rare.
  • Vent Free logs cannot be repositioned once they are installed. This is due to vent free log sets having to maintain a complete clean burn which requires the logs to sit on the grate in only one way.
  • Some states (California, Massachusetts, and a few others) require special permits in order to operate non-vented appliances indoors. It is the customer's responsibility to know his or her local codes and limitations.
