threaded hanger bracket assembly is located on each side of the heater. If a fan-type
unit has been ordered with optional, factory-installed, four-point suspension (Option

A blower-type heater is equipped with standard four-point suspension. Two 3/8-16
threaded hanger bracket assemblies are located on each side of the unit. Each hanger
bracket assembly is designed for threaded rod attachment.

Tables in Paragraph 4.2. (Note: If installing Option CK19 hanger kit, suspension points
change; see FIGURE 11, page 13.)
