7. Planning the Installation
Planning the installation first requires selecting the most appropriate installation approach. The
chart below offers suggestions for the most effective installation approach by considering a few
important factors. Further details on the two main types of installations are provided below.
7.1 Sizing the Damper & the Duct
The required amount of make-up air will vary for each home, depending on the home
characteristics, the amount of exhaust ventilation provided within the home, and the local
building code requirements. A well designed solution considers the home size, the home’s air
tightness, the exhaust rate, the presence of combustion appliances, and the installation
configuration of the Damper. To assist building professionals in specifying code-compliant
makeup air solutions and developing product-specific cut-sheets, Broan-NuTone has developed
an on-line tool called the Range Hood Make-Up Air Specifier, available on Broan, BEST, and
NuTone websites.
