WARNINGS: Check the supporting structure to be used to verify that it has sufficient
load carrying capacity to support the weight of the heater. Suspend the heater only
from the threaded nut retainers or with a manufacturer provided kit. Do NOT suspend
from the heater cabinet.
See FIGURE 1A or 1B for the appropriate hanging locations, and install the
½”-13 spring nuts in the strut that is attached to the top of the unit. Comply
with the requirements in FIGURE 4A when using threaded rod. If ordered with
swivel connectors for 1” pipe, Option CK10, attach the swivels to the spring
nuts according to illustration in FIGURE 4B and suspend with 1” pipe.
WARNING: All heaters must be level for proper operation. Do
not place or add additional weight to the suspended heater.

 Mounting is the responsibility of the installer. Verify that the supporting
structure has sufficient load-carrying capacity to support the weight. (See
weights, page 8.)
 Prior to installation, be sure that the method of support is in agreement with
all local building codes. Check for service platform requirements.
 Maintain a minimum of 2” (51mm) clearance from the discharge air
openings to structural supports. Additional clearance will be required if an
optional nozzle is to be field installed.
 Determining the need for installing vibration or noise isolation is the
responsibility of the installer.
 To prevent potential movement, field-supplied angles must be placed
around the perimeter of the heater to anchor it to the structural supports.
 Structural supports must be placed as shown to prevent damage to the
heater.
 All structural supports must be noncombustible materials.
