stepdown transformer kit
(Option CF or CG), the
stepdown transformer
bracket is part of the
heater suspension and
must be installed prior to
hanging the heater. Follow
the instructions on the
installation sheet included

A
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
