Abstract
A heat exchanger for a cooking system is provided. The heat exchanger includes a central axis, an inlet module, and a heat exchanger module removably coupled to and adjacent the inlet module along the central axis. A fluid duct is provided that extends through the inlet module and the heat exchanger module along the central axis. The inlet module includes a plurality of headers positioned about an outer perimeter of the inlet module, a plurality of tubes extending radially across the fluid duct between the plurality of headers, and a plurality of caps coupled to the plurality of headers, wherein each cap is configured to be removed from a corresponding one of the plurality of headers to expose one of the plurality of tubes through the corresponding one of the plurality of headers.
