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.
