Intake device for a chimney termination

A termination assembly for a chimney, the termination assembly comprising:

• an exhaust layer having an exhaust tube adapted to receive exhaust air from an appliance, wherein an outlet opening of the exhaust tube terminates in the exhaust layer;
• an intake layer separated from the exhaust layer, the intake layer comprising:
• an enclosure defining a positive pressure area within the enclosure and the enclosure having a plurality of openings directing intake air at an angle toward the positive pressure area, wherein the angle is in the range of 20-degrees to 85-degrees to a longitudinal axis of the enclosure;
• an intake tube adapted to receive intake air at an inlet opening positioned in the positive pressure area;
• wherein the positive pressure area in the intake layer has pressure greater than the atmospheric pressure outside the termination assembly and in the exhaust layer to prevent flow in the exhaust tube from being reversed.

• an intake layer separated from the exhaust layer, the intake layer comprising:
• an enclosure defining a positive pressure area within the enclosure and the enclosure having at least one opening formed between at least two rings being spaced apart, wherein the at least one opening has a cross-sectional area that decreases from an exterior surface of the enclosure toward the positive pressure area within the enclosure;
• an intake tube adapted to receive intake air at an inlet opening positioned in the positive pressure area;
• wherein the positive pressure area in the intake layer has pressure greater than the atmospheric pressure outside the termination assembly and in the exhaust layer to prevent flow in the exhaust tube from being reversed.
