INSTALLATION—CONTINUED
Heater Suspension—Continued
⚠ CAUTION ⚠
• Before lifting the heater, verify that any screws used for holding shipping brackets were re-
installed in the cabinet.
• Before lifting heater model UBZ or UDZ, any unused suspension points on the control side of
the heater MUST be plugged.
• When the heater is lifted for suspension, support the bottom of the heater with plywood or other
appropriately placed material. If the bottom is not supported, damage could occur.
NOTE: Four-point suspension is recommended. Two-point suspension is permitted only on unit
sizes 030–125 of models UDX and UDZ when installed without a downturn nozzle or stepdown
transformer.
• A 3/8-16 threaded nut retainer is located at each suspension point. The heater may be suspended using either
3/8-inch threaded rods or a hanger kit option package.
• On heater models UBX and UDX, shipped-separate option packages—that should be installed before the heater
is suspended—include vertical louvers, high-elevation kit, multiple heater control, sensor for DDC control, and/
or stepdown transformer. Installation instructions for these option packages are included in the option package.
• In the literature bag shipped with the heater, there are three capscrews (PN 203311) and sealing washers (PN
61658). On UBZ and UDZ models, these capscrews and washers must be used to seal any unused holes in the
top of the heater (control side) after attaching the hanging hardware (see Figure 5).

Suspension of Heater Using Option CK8 or CK10 Hanger Kit
Options CK8 (two-point suspension, UDX/UDZ unit sizes 030–125) and CK10 (four-point suspension) are for
suspending the heater using swivel connectors connected to 1-inch pipe. Attach the swivel connectors at the 3/8-16
threaded nut retainers. Ensure that the swivel connectors are locked to the heater as shown in Figure 6.
