Abstract:
A horizontal vent terminal assembly for simultaneously flowing outside combustion air to a combustion device located within a dwelling having an exterior wall and ejecting combustion gases discharged from the combustion device to the outside of the dwelling, said horizontal vent terminal assembly comprising:(a) a combustion gas vent pipe for receiving and axially ejecting combustion gases discharged from a combustion device, said combustion gas vent pipe having an open discharge end extending horizontally outwardly beyond an outside surface of an exterior wall;(b) a head chamber positioned over said open discharge end of said combustion gas vent pipe, said head chamber including a plurality of outlet ports and splitting means for splitting and deflecting combustion gas travelling axially along said combustion gas vent pipe to said plurality of outlet ports, said splitting means having an inner end adjacent said discharge end of said vent pipe and an outer end spaced from said inner end, a pair of first side shields coupled to said splitting means, each of said first side shields having an inner end and an outer end said outer end being spaced from said outer end of said splitting means, and a pair of second side shields, each of said second side shields being spaced from a respective first side shield and having a first end overlying said outer end of said first side shield to form a gap and a second end spaced from said outer end of said splitting means to form said outlet ports;(c) a combustion air inlet pipe colinearly disposed outwardly around said combustion gas vent pipe and defining therewith an annular flow space operative to receive a flow of combustion air, said inlet pipe having an inlet end and an outlet end; and(d) a baffle disposed between said outlet ports of said head chamber and annular flow space of said combustion air inlet pipe to inhibit combustion gas from being mixed with a flow of combustion air into said air inlet pipe.
