Venting Requirements:
• Unit is to be used with KitchenAid external blower kit KPED890T.
• Ductwork needed for installation is not supplied. Wall cap is NOT
provided. Ductwork can extend either through the wall or roof. The
length of the ductwork and number of elbows should be kept to a
minimum to provide efficient performance. The size of the duct work
should be uniform. Do NOT install two elbows together. Flexible
ductwork is NOT recommended. If it is used, calculate each foot of
flexible ductwork as two feet of straight metal ductwork. Flexible
elbows count twice as much as standard elbows. Use metal ductwork
only. Make sure there is proper clearance within the wall of floor for
exhaust duct before making cutouts.
• For best performance, use no more than three 90° elbows. If more
than one elbow is used, make sure that there is a minimum of 24" of
straight duct between any two elbows. It is recommended that you
use round duct instead of rectangular duct, especially if elbows are
required. If rectangular duct is required, it should be transitioned to
9" round as soon as possible. To calculate the length of system you
need, add the equivalent feet for each duct piece used in the system.
• Recommended standard fitting equivalents:
3 1/4" x 10" 90° elbow = 5 feet straight.
3 1/4" x 10" 45° elbow = 7 feet straight.
3 1/4" x 10" wall cap = 0 feet straight.
3 1/4" x 10" 90° flat elbow = 12 feet straight.
