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.
