ABSTRACT:
A fireplace downdraft regulator having a first end and a second end, such regulator extending across the top of a fireplace opening, such regulator having an aerodynamic draft header portion having a front face and a height and length, such draft header portion extending downwardly and rearwardly from the fireplace top at approximately 45 degrees to a vertical to form a corner angle and then extending upwards at approximately 90 degrees to the aerodynamic draft header portion to form a deflector portion with the deflector portion angled upwards into the chimney such that the inside portion of the regulator deflects downdrafts back upwards within the chimney and the aerodynamic draft header portion aids in drawing air from the room, which air travels down its front face and around the corner angle and back up the outside face of the deflector portion to help increase the updraft of air within the chimney.
