Hood Exhaust Duct: Outside ventilation requires a HOOD EXHAUST DUCT. Read the 
following carefully.
Exhaust Connection: The hood exhaust has been designed to mate with a standard  
3-1/4" x 10" rectangular duct. If a round duct is required, a rectangular-to-round  
transition adaptor must be used. Do not use less than a 6" diameter duct. 
Rear Exhaust: If a rear or horizontal exhaust is to be used, care should be taken to 
align exhaust with space between studs, or wall should be prepared at the time it 
is constructed by leaving enough space between the wall studs to accommodate 
exhaust.
Maximum Duct Length: For satisfactory air movement, the total duct length of 3-1/4" 
x 10" rectangular or 6" diameter round duct should not exceed 140 equivalent feet.
ELBOWS, TRANSITIONS, WALL AND ROOF CAPS: etc., present additional resistance to 
airflow and are equivalent to a section of straight duct which is longer than their  
actual physical size. When calculating the total duct length, add the equivalent length 
of all transitions and adaptors plus the lengths of all straight duct sections. The chart 
below shows the approximate feet of equivalent length of some typical ducts.
