Abstract
A direct venting system for an indoor domestic type water heater vents the combustion chamber of the water heater directly with the outdoor atmosphere by means of natural convection both to supply incoming combustion air and to expel flue gases. A conduit assembly extends from an indoor end associated with the water heater to an outdoor end in communication with the outdoor atmosphere, and provides continuous combustion air inlet and flue gas outlet plenums to isolate the combustion chamber of the water heater from the indoor room air.
