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.
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.
These products burn natural gas and therefore again there is no inconvenience of ashes or soot, smoke or any wood by-products.
