1. SELECT BLOWER OPTION AND INSTALL DUCTWORK
Either an interior or exterior blower or in-line blower may be used with this hood. The NuTone premier NP64000 Series must
be installed with blower models P5, P8, HLB3, HLB6, HLB9, HLB11, 331H, 332H, 335 or 336 only. Other blowers
cannot be substituted. (Blowers sold separately).
Plan where and how the ductwork will be installed.
If installing in-line blower, refer to instructions packed with in-line blower and follow steps 1 up to 3, 6, 9, 10,
12 and up of this manual.
Install proper-sized ductwork, elbows and roof or wall cap for the type of blower you are installing. If using 7” or 8” round
ducts, or 3
1
/4’’ x 14’’ duct, use a transition. Use 2” duct tape to seal duct joints.
The minimum hood distance above cooktop must not be less than 20’’ for an electric range and 24’’ for a gas
range. A maximum of 30” above cooktop is highly recommended for best capture of cooking impurities.
Distances over 30” are at the installer and users discretion.
