Osburn 5" Air Intake Termination with Clamps

The part that finishes a fresh-air run on the outside wall: a 5" intake termination with the two clamps that fix the insulated pipe to it and to the fireplace's 5" adapter — neither of which comes with the Osburn Horizon. It mounts through the wall open side down, where snow will not block it and away from exhausts and gas meters, no more than 10 feet above or 3 feet below the base of the fireplace. Pair it with the 5" insulated flex pipe and the 5" airtight intake register. $66.
