Bought a 7" round duct can it be changed to a rectangular duct?
The 42000 series is made to be installed on a 7" round duct only. However, once you connect your 7" round duct to the range hood, you may transition to 3 1/4" x 10" rectangular duct, using the Broan model 412H transition piece. If you have further questions, please contact the Broan Technical Support group at 800-637-1453.
