Equivalent lengths of duct pieces are based on actual tests and 

reflect requirements for good venting performance with any vent 

hood.

*  IMPORTANT: If a rectangular-to-round transition 

adaptor is used, the bottom corners of the damper 

will have to be cut to fit, using the tin snips, in order 

to allow free movement of the damper.

NOTE: If you need to install ducts, note that the total duct

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. $OVRPDNHVXUHGDPSHUVVZLQJIUHHO\DQG

If a round duct is required, a rectangular-to-round  

transition adaptor must be used. Do not use less than  

a 6s diameter duct.

s x 10s rectangular or 6s diameter round duct should 

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 approximate feet of equivalent length of some typical 

duct pieces.
