Abstract:
A horizontal air intake and combustion gas vent terminal positionable in an exterior wall of a building for admitting outside air to a fuel fired furnace in the building and venting combustion gas therefrom to the outside of the building, the terminal comprising:(a) a vent conduit for receiving combustion gases from the furnace, the vent conduit having an open vent outlet end positionable to extend outwardly from the exterior wall for venting the combustion gases to the outside of the building;(b) an intake conduit disposed around the vent conduit having an air flow space defined therein in cooperation with the vent conduit for receiving a horizontal flow of outside air through an open intake inlet end and delivering said air through the air flow space to the furnace, the intake inlet end being positionable between the vent outlet end and the wall;(c) a sleeve member disposed around the intake conduit having a first end merged with the intake conduit and a second end positionable to extend outwardly from the wall to a position intermediate the intake inlet end and the vent outlet end, the sleeve member having a first surface; and(d) a shield member disposed around the vent conduit and spaced apart from the intake inlet end, the shield member extending from the vent conduit towards the sleeve member to a position wherein the shield member substantially blocks direct axial access of air to the intake inlet end, the shield having a second surface,whereby the first and second surfaces cooperate to form an air intake passage therebetween, end the air intake passage being in flow communication with the intake inlet end.
