Abstract
Elongated, vertical air chambers having an open upper end and a closed lower end are located within or attached to the walls of a fireplace, where the upper ends open only into the interior of the fireplace. Air heated within the air chambers rises into the fireplace to increase the drafting efficiency, and is replaced in the air chambers by relatively cooler, draft inhibiting air drawn only from the upper interior of the fireplace. In large furnace applications, the air chambers are located in the lower portion of the chimney.
