Abstract:
An improved method and apparatus allows fresh air to be introduced into a building through action of a special manifold which directs air entering the building through the furnace combustion feed tube to be introduced into the interior atmosphere of the building, while air from the interior of the building is directed to the furnace and ultimately exhausted to the exterior of the building.
