Abstract
A system for oxidation of carbon monoxide produced from gas log sets used in a vent free mode in a wood burning fireplace or fireplace insert. In the system a vent chamber is placed in the top of the combustion chamber. The vent chamber has three sides, a ceiling and a floor the front of the chamber being open and venting outside of the firebox. The vent chamber is positioned in the top of the fireplace combustion chamber. The floor of the vent chamber has a hole cut into it and a low shape profile, low pressure drop catalytic screen placed in the hole so that the exhaust can pass through the catalyst into the chamber and then vent to the room. A curtain may be placed below the chamber vent and in front of the catalyst to act as a baffle or dam to restrict the flow of rising hot exhaust and redirecting it through the catalyst.
