A hand held vacuum cleaner unit and docking assembly for a central vacuum system is shown. The hand held vacuum cleaner has a handle, a suction nozzle, a trigger switch to turn on a battery powered suction motor and an outlet port. The docking assembly fits into a central vacuum cleaner mounting plate, and provides a cradle to store the hand held vacuum cleaner. Recharging contacts, a latch mechanism, seals and an intake port are provided on the docking assembly. When the hand held unit is in the docking assembly it may be electrically charged, and emptied of dirt and debris by activation of the central vacuum system. The docking assembly also includes an access port for a conventional central vacuum hose.

A passive vent for venting a building enclosure having an opening in a roof portion, the vent being adjustable for mounting on roof portions of different slopes. The vent has a base pivotally attached to a vent structure with a pair of pivot joints. The vent structure has a collar attached to a vent body having a cover. At least one gas permeable screen is positioned on the vent body between the cover and the collar. The base comprises a lower attachment structure for attaching the base to the roof portion over the opening. An aperture through the lower attachment structure permits gas to pass in to and out of the opening in the roof portion through the base. A wall including a pair of opposed curvilinear wall sections surrounds the aperture. The pivot joints define a pivot axis about which the vent structure pivots along a range of angles relative to the base. The collar is sized and shaped to overlap portions of the aperture surrounding wall to maintain a continuous wall between the collar and the aperture surrounding wall along the range of angles. At least one securement means secures the vent structure in one of the range of angles relative to the base.
