Vent-free fireplaces have no exhaust vent

Vent Free Fireplaces

These fireplaces need no chimney or vent, making installation costs minimal. These fireplaces are cost efficient and convenient for heating up a room. The units are “zero or close clearance” which means they can be put right up against the wall or only a few inches away, allowing great flexibility in placement.

Vent Free Fireplaces

A vent-free fireplace has no exhaust vent, so the gas is simply connected to the unit and the flames burn inside the unit without a vent. The blue flame of a vent-free gas fireplace unit is designed to provide nearly complete fuel combustion, resulting in less carbon monoxide and soot than a vented model. Heat stays in the home, rather than being let out through a chimney or other outlet.

Although they may sound somewhat dangerous (and may not be installed in certain places), they are put to pass all current safety and emission standards. Vent-free fireplaces are more commonly known as Oxygen Depletion Sensors (ODS). When oxygen levels drop, the ODS will cut off the flame. Unlike with a direct vent fireplace, on a vent-free fireplace the damper does not need to stay open.
