TITLE: FIREPLACE DRAFT CONTROL DAMPER Abstract of the Disclosure A draft control is described for selectively admitting ex- terior fresh air to assist combustion within the interior of a fire- place. The draft control is comprised of two interconnected and rela- tively slidable plates. The plates are dimensioned relative to a standard firebrick to facilitate installation in existing fireplace structures. Cool, exterior air is allowed to pass through selectively aligned apertures extending through both plates into the firebox. The plates may slide between this operative position wherein the apertures are in open contact and a closed position wherein the apertures of one plate are out of alignment and do not permit free passage of air into the fireplace interior.
