What about carbon monoxide? Don't you require an exhaust?

Our Answer:

We understand your concern about a gas-burning appliance that has no exhaust. Vent-free fireplaces and stoves are designed to burn cleanly, so there is no incomplete combustion, and, thus, no carbon monoxide. The clean combustion by-products are primarily carbon dioxide and water vapor. All vent-free appliances are also equipped with an oxygen depletion sensor (ODS). This sensor will shut down the appliance if the oxygen in the room drops below normal levels, and well before any dangerous levels are reached. For more information about vent-free fireplaces and stoves, please see our gas fireplace and stove buying guide.
