NuTone 605RP - Manual (Page 2)

CERTIFIED TEST DATA
Air delivery and sound level ratings are certified by
the Home Ventilating Institute Division of AMCA, based
on testing performed by an independent third party testing
laboratory, in accordance with HVI standards. This NuTone
model is listed by Underwriters' Laboratories Inc.
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.
