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 model is listed by Underwriters’ Laborotories Inc. and
certified by the Canadian Standards Association.
*Optional accessory items available. Please refer to
the NuTone catalog or website (www.NuTone.com) for
complete listing.
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 curve and draw a
vertical line down to the CFM scale and read the system
air performance.
