Natural Gas Vented Logs operate with an open chimney flue, or damper, and connect to the natural gas line in your home. A Vented Fireplace Log Set will give you a dancing, bright yellow flame that more accurately simulates a real fire, but will emit less heat than a vent-free log set because of the open damper. Vented Log Sets have burners that operate at lower temperatures to help produce a more realistic fireplace experience. However, when gas is burned at a lower temperature, more pollutants are put into the air, which is why the vent must remain open at all times. We sell Natural Gas Vented Fireplace Logs of multiple sizes from popular manufacturers including Empire, Peterson Real-Fyre, Monessen, and more.
