General information
NOTE: If you need to install ducts, note that the total 
duct length of 3 ¼˝ x 10˝ rectangular or 6˝ diameter 
round duct should not exceed 140 equivalent feet.
Outside ventilation requires a HOOD EXHAUST DUCT. 
Read the following carefully.
NOTE: It is important that venting be installed using 
the most direct route and with as few elbows as 
possible. This ensures clear venting of exhaust and 
helps prevent blockages. Also, make sure dampers 
swing freely and nothing is blocking the ducts.
Exhaust connection:
The hood exhaust has been designed to mate with a 
standard 3 ¼˝ 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.
Maximum duct length:
For satisfactory air movement, the total duct length of 
3 ¼˝ 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 lengths of all 
transitions and adaptors plus the length of all straight 
duct sections. The chart below shows you how to 
calculate total equivalent ductwork length using the 
equivalent length in feet of some typical ducts.

*  IMPORTANT: If a rectangular-to-round 
transition adaptor is used, the bottom 
corners of the damper will have to be cut to 
fit, using tin snips, to allow free movement 
of the damper.
Equivalent lengths of duct pieces 
are based on actual tests and reflect 
the requirements for good venting 
performance with any vent hood.
