This invention relates to a device which is installed in series with the smoke stack of an oil burner whereby the configuration of the device provides the means to act as an aerodynamic check valve and to stabilize and isolate downdraft effects in the smoke stack of a burner caused by adverse or varying wind conditions so as to insure against subsequent faulty burner operation. Also, the use of this invention, and its objectives, has application in the smoke stack of other like heating entities or duct work requiring the movement or discharge of gases; some of which are wood burning stoves, coal burning stoves or gas burning heating equipment.
