Are all gas fireplaces vented?

“Fully Vented” gas logs must be burned in a fireplace that is capable of burning real wood and must be burned with the damper open. The reason for this is that they do not burn the gas cleanly and create exhaust that is very similar to burning a real wood fire. This exhaust needs to be able to go up the chimney.

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. The risk to your health is a long-standing and ongoing debate.

Also Know, are vented gas fireplaces efficient?
