Chimney attic ventilator

Abstract

The purpose of this invention is to allow the use of power roof vents in locations where they are otherwise undesirable. It disguises the power roof vent as a chimney and cap that are used with a combustible fuel source. This is accomplished by building a false chimney (that resembles a masonry or prefabricated chimney suitable for combustion gasses) and mounting the power roof vent on top of it. The invention also increases the efficiency of power roof vents because of the “chimney effect” resulting from the power roof vent being mounted higher than the standard installation—directly on the roof. The chimney effect is as follows: Warm air moving up thru a space and out a vent creates a vacuum. This forces air up from lower level vents. The greater the difference in height between the high and low vents the more movement of air will take place.

1 . Provides an aesthetically pleasing alternative to mounting a power attic vent on a roof. The result appears to be a high-temperature vent chimney with a dome cap typical of dwellings with fireplaces or wood stoves.
