Ventless gas logs (often referred to as “Vent Free” gas logs) have specially designed burners that burn the gas cleanly and produce almost no exhaust somewhat like the way a gas range in a kitchen works. Since there is little or no exhaust, they can be burned with the damper closed.
Venting any type of combustion is ideal. As forwarded by the ventless gas appliance industry, though, ventless gas fireplaces can be safely used because they burn a low enough quantity of gas that it will not present a hazard.
Similarly, 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.
