    I am about to install a QP430SS30" 630 CFM Stainless Steel Under Cabinet Range Hood. Will I need a Pressure Relief Damper with Wall Cap and 6" Collar or 7" collar. The Broan range hood I am replacing is a 40,000H.

    Thank you for your question on the model QP430SS range hood. If the QP430SS is vented vertically with round duct work it would require seven inch duct. You should install some sort of damper in the duct work, at least where the duct exits the house. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.
