Model SC duct furnaces have two-point suspension. See hanger centerline dimen-
sions in FIGURE 2, Paragraph 4.2.
At each suspension point, the unit is factory-equipped with a free-turning, female, 1"
NPT pipe hanger. Suspend by connecting the pipe hanger to a 1" threaded pipe. See
suspension method on the left in FIGURE 3. As an alternative method, the factory-
installed pipe hanger may be removed and the heater suspended as illustrated on the
right in FIGURE 3.
