Abstract:
A carbon monoxide ventilation system, for use in an interior area and ventilating to an exterior area of a building, comprising in combination:a building having a wall having an interior mounting surface and an exterior surface adjacent to ambient outside air; a vent in communication with said exterior surface of said wall; a boiler and burner within said building with an exhaust gas flue extending from said boiler through an outside wall of said building; a fan unit located in the interior area near said flue, said fan unit connected to the vent, said fan unit having a motor and a propeller for drawing air from the interior and expelling it to the exterior through said vent, said fan unit having inlet vents on a surface thereof so that any exhaust fumes escaping from said flue would enter said fan unit; said fan unit having a filter for capturing particle before detrimentally engaging said propeller; said fan unit having a sensor for detecting the presence of carbon monoxide entering through said inlet vents and supplying power to said fan unit without affecting operation of said boiler and burner so that said boiler and burner can continue to operate without exhaust fumes seeping into living quarters of said building, said sensor having an alarm indicating device and a reset button, wherein the indicating device remains activated until reset by said reset button; and said vent having a downward extending outlet for preventing entrance of rain and snow therein.
