Vented gas logs burn like a real wood fire with a yellow flame that produces smoke. They must be burned in a wood burning fireplace with the damper open, so smoke goes up the flue along with most of the heat. Ventless (vent-free) gas logs burn cleanly with a lower flame that does not smoke.
Also Know, do ventless gas fireplaces give off carbon monoxide? As a result, “When they’re running correctly, ventless gas fireplaces do a pretty good job,” says Bailes. Incomplete combustion creates the dangerous molecular byproduct carbon monoxide (CO)—an odorless gas that causes brain damage and even death at high-enough exposure levels.
Likewise, do gas fireplaces need venting?
Ventless fireplaces fueled by gas or propane rely on indoor air for combustion, and they exhaust a low level of their combustion gases into the room in which they’re located. A chimney or flue isn’t necessary. In fact, ventless fireplaces generally are just for aesthetics and supplemental space heating.
How do I know if my gas fireplace is vented or ventless?

- Follow the gas line from beneath the logs to where it disappears in the wall or floor. If the gas is merely contained by a simple gas line, then the logs are vent free.
