ABSTRACT:
A ventilation system for urging flue gases from an exhaust source through an exhaust conduit has an exhaust outlet for venting the gases and an exhaust inlet communicating with the exhaust source. A blower fan is provided for creating a positive air flow away from the exhaust inlet to urge the flue gases through the exhaust conduit and out of the exhaust outlet. A blower pipe channels air from the blower fan into the exhaust conduit past the exhaust inlet so as to create a venturi effect to draw exhaust from the exhaust inlet into the exhaust conduit. Duct work may be provided so that the blower fan draws fresh air from the ambient, namely from outside the structure housing the exhaust sources, rather than from inside the structure.
