INSTALLATION
• Not for use in kitchens. Do not mount over range,
bathtub or shower stall.
• The ventilator consists of the housing, mounting
brackets, junction box, power unit/blower assembly,
damper section and grille assembly.

Speed control must be purchased separately;
refer to NuTone’s catalog.
• Installation Instructions are provided with each unit.
ARCHITECT'S SPECIFICATIONS
Twin-Blower Ventilator shall be Model QT130 as
manufactured by NuTone according to listed specifications.
Unit shall ventilate 120 CFM when ducted vertically
or 120 CFM when ducted horizontally at .10” S.P.
at a sound level of .90 sones. Housing shall measure
141⁄4" x 10" x 9" deep and connect to 31⁄4" x 10" duct.
CERTIFIED TEST DATA
HVI-2100 CERTIFIED RATINGS comply with new testing
technologies and procedures prescribed by the Home
Ventilating Institute, for off-the-shelf products, as they are
available to consumers. Product performance is rated at 0.1
in. static pressure, based on tests conducted in AMCA's
state-of-the-art test laboratory. Sones are a measure of
humanly-perceived loudness, based on laboratory
measurements. This NuTone model is listed by Underwriters'
Laboratories Inc. and Certified by the Canadian Standards
Association (CSA.)
The air delivery of a ventilating system may be
determined by:
1. Determine the equivalent duct length for each 90 degree
elbow by adding one foot of duct length for each inch of
duct diameter, i.e., a 4 inch diameter duct elbow equals
4 feet equivalent duct length and an 8 inch diameter duct
elbow equals 8 feet equivalent duct length.
2. Add the total straight length of duct and the equivalent
length for each elbow to obtain the total equivalent duct
length.
3. Locate the intersection of the fan performance curve
and the total equivalent duct length curves and draw a
vertical line down to the CFM scale and read the system
air performance.
(NOTE: 31⁄
4
" x 10" duct equals 6 inch diameter duct.)
