Abstract

A water heater including a water container; a combustion chamber adjacent the container, the combustion chamber having at least one flame arrestor to admit air and extraneous fumes into the combustion chamber and confine ignition and combustion of the extraneous fumes within the combustion chamber; a burner associated with the combustion chamber and arranged to combust fuel to heat water in the container; an air diverter positioned between the flame arrestor and the burner and adapted to channel at least a portion of combustion air passing through at least a portion of the flame arrestor to a position for mixture with the fuel prior to entering the burner to ensure uniform combustion; and a flange positioned above the air diverter to which the flames attach and thereby reduce combustion temperatures; the combined effect of which is to optimize combustion performance and minimize NO and CO emissions.
