If it is determined that the blower CFM is greater than allowed or desirable, see Paragraph 14 for instructions on determining the correct size of bypass duct required. To determine temperature rise, the inlet and outlet air temperatures should be measured at points not affected by heat radiating from the heat exchanger. The following charts show the approved temperature rise range with the required CFM and the internal pressure drop for each size of unit. Model EEDU (80% thermal efficient) Size
