fan-type unit heater is equipped with standard two-point suspension. A 3/8-16

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

BJ6), it will have two threaded hanger brackets on each side.

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.
For both "standard" and "optional" suspension point dimensions, see Dimension

Tables in Paragraph 4.2. (Note: If installing Option CK19 hanger kit, suspension points

change; see
