Claim 0:
1. An insert for an exhaust termination, comprising:
a frame configured to fit at least partially within an existing louvered exhaust termination frame;
a hinge member; and
a single flap operatively connected to the frame via the hinge member configured to move between an open and closed position with an exhaust flow of a dryer to connect a dryer exhaust outlet to an ambient external environment through the exhaust termination, wherein in the closed position the single flap is configured to cover the exhaust termination to prevent ingress of ambient air into the exhaust termination and wherein in the open position the single flap is configured extend away from the exhaust termination to allow egress of the exhaust flow of the dryer to ambient, wherein the single flap is biased towards the closed position and is configured to rotatably move from the closed position to the open position with the exhaust flow of the dryer through the exhaust termination,
wherein the frame includes an aperture defined therethrough, wherein the aperture includes an octagonal shape having a pair of parallel horizontal edges, a pair of parallel vertical edges, and four diagonal edges each diagonal edge connecting between one horizontal edge and one vertical edge, wherein four corner fastener holes are defined in the frame proximate a respective diagonal edge.
