Balanced flue sealed vent terminal assembly

摘要

The present invention is directed to a sealed vent terminal assembly intended for use in association with high-efficiency oil fired furnaces or boilers. The terminal assembly of the present invention is designed to simultaneously flow outside combustion air to the furnace or boiler and eject combustion gases discharged from the furnace or boiler. It comprises a combustion gas vent pipe for receiving and axially ejecting the combustion gases, the combustion gas vent pipe having an open discharge end, a head chamber positioned over the open discharge end of the combustion gas vent pipe, the head chamber including a plurality of outlet ports and means for splitting and deflecting the combustion gases to the plurality of outlet ports, a combustion air inlet pipe colinearly disposed outwardly around the combustion gas vent pipe and defining an annular flow space operative to receive a flow of combustion air and a baffle disposed between the outlet ports of the head chamber and the annular flow space of the combustion air inlet pipe to inhibit the combustion gas from being mixed with the flow of combustion air. The terminal assembly of the present invention overcomes the difficulties of known devices as it operates effectively and efficiently in all wind conditions. The invention is further directed to a clamping system designed for use in association with the sealed vent terminal assembly.
