Kenmore PRO 233.51063600 Use & Care Manual page 6

Kenmore range hoods are designed to perform efficiently when attached to long runs of duct. As a point of reference, this hood
will function at approximately 80% of its rated air performance when 100 equivalent feet of 7" round ductwork is attached (for
600 cfm blowers) or 125 equivalent feet of 10" round duct is attached (for 1200 cfm blowers). Use this chart to calculate the
equivalent duct length of your system. Note that 7" round is the minimum recommended duct size for 600 cfm blowers, and 10"
round is the minimum recommended duct size for 1200 cfm blowers.
