Installing duct for range hood

I want to install a ducted range hood. What are the local building codes for venting outside the home? I live in Littleton CO (Douglas County). The range hood will be installed under a kitchen cabinet and against an exterior wall, duct is made of 30 gauge galvanized steel (2 90 degrees elbows to avoid a stud). I will be using the 7 inch round galvanized wall vent with spring return damper. Are there any specific requirements for the wall vent location?

Hi jcvanduc,

While there is a national building code, many cities use an enhanced version based on location and climate. In order to determine the code requirements in your city, contact your local building department.

They will specify the type of vent, materials allowed and location of the vent.
