Abstract: A throttled vent termination or cap for use in conjunction with a direct vent appliance and venting system is provided. The direct vent termination includes an inner pipe and a concentric outer housing surrounding the inner pipe to form a void between the inner pipe and the outer housing. The void adapted to provide intake air to the air intake section of the vent system. An end cap is provided at a first end of the outer pipe, the inner pipe to the end cap and having an exhaust opening therein. An intake region is formed in the outer housing providing access to the void. A throttle cover which is configured to be movably positioned and thereafter secured at one of a number of positions over the intake region using a throttle guide is provided to thereby regulate air flow into the void.

Abstract: A venting system includes a venting installation cap assembly for a venting system having at least an outer wall and an inner exhaust tube. The assembly includes an exhaust cap having an exhaust path coupled to the inner exhaust tube defined by a pipe section. A planar support ring having an annulus through which the pipe section passes rests on the outer tube or an adapter to the outer tube. The ring annulus surrounds the pipe section and has a diameter greater than a diameter of the outer wall. The planar support ring includes a plurality of airflow regions, surrounds the exhaust path and providing an airflow path between an exterior and a region between the outer wall and the inner exhaust tube.

Abstract: A securing assembly with a securing structural element adapted to couple a first exhaust system part to a second exhaust system part. The assembly includes a element having a first surface attached to an exterior surface of the first exhaust system part, the element engaging at least a portion of the exhaust system part. The element may be cylindrical or rectangular. A bottom surface of the element includes a plurality of energy directors extending from the bottom surface to a height above the bottom surface. The directors allow sonic welding of the element to an arcuate side of the exhaust system part.

Abstract: A venting system includes a venting pipe comprising a chase through a structure. The chase includes a first end positioned adjacent an appliance installation, a second end exiting a structure and a third end adjacent another appliance. A vent tube comprising a sealed non-corrosive material is provided in the chase between the second end and the third end, itself coupled to a high efficiency appliance. The vent tube has a first end and a second end and is positioned between the second end of the venting pipe and the third end of the venting pipe. The vent tube is coupled to a first appliance and the venting pipe is coupled to a second appliance. A vent cap is coupled to the second end of the first vent tube and to the second end of the venting pipe.
