The heat exchanger should rest on a flat supporting sur-
face. If other components, such as a duct or unit section,
are connected to the top of the heat exchanger, they
must not rest on the exchanger.
A supporting center beam must be provided for size
200 and larger units. The maximum permissible deflec-
tion of the load-bearing centre beam when supporting
the weight of the heat exchanger and any other compo-
nents is 0.04 inches.
