Abstract: Vent terminal apparatus and methods are provided for covering vent pipes in an HVAC system, e.g., air intake and combustion gas exhaust pipes of a furnace or boiler. The vent terminal includes a body defining a shielded air inlet configured to fluidly communicate with an air intake pipe, and an exhaust opening configured to fluidly communicate with an exhaust pipe. The vent terminal also includes a nozzle configured to couple with the body and defining a flowpath therethrough. When the exhaust opening of the body is in fluid communication with the exhaust pipe and the nozzle is coupled with the body, the flowpath is in fluid communication with the exhaust pipe via the exhaust opening and the flowpath is oriented at an acute angle relative to the exhaust pipe.

Abstract: An adapter for controlling airflow between a first element and a second element in an air conditioning system is provided including a frame having a first frame piece and a second frame piece. A portion of the second frame piece overlaps the first frame piece. The second frame piece slides relative to the first frame piece making a dimension of the frame adjustable. An upper portion of the frame attaches about an end of the first element and a lower portion of the frame attaches about an end of the second element.

Abstract: A combined air intake and combustion gas vent terminal is provided for engagement with at least one of a pair of pipes extending horizontally and being spaced apart to accommodate the inward flow of combustion air and the outwardly flow of exhaust air from a furnace. The terminal assembly is installed entirely outside of the building and has a stepped structure for engaging the pipes such that it can accommodate different sized pipes.
