WARNINGS
Check the supporting structure to be used to verify that it has
sufficient load carrying capacity to support the weight of the unit.
Suspend the heater only from the threaded nut retainers or with
a manufacturer provided kit. Do NOT suspend from the heater
cabinet.
5.2 Lifting and Suspending
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. Before hanging, verify that any screws used for holding shipping brackets were
re- installed in the cabinet.
Model UDAS - Whether using the suspension points or a hanger kit. when installing
a Model UDAS, any unused suspension points on the control side of the heater
MUST be plugged. Plug these holes with the 1/2" long cap screws and flat washers
shipped in the bag with the heater. (See FIGURE 6.)

WARNING
Unit must be level for proper operation. Do not place or add
additional weight to the suspended heater. Hazard Levels, page 2.
5.2.1 Two -Point or Four -Point Suspension
The heater is equipped for either two -point or four -point suspension. A 3/8 " -16 threaded
nut retainer is located at each suspension point. NOTE: Four -point suspension is
required when installing an optional downturn nozzle. See Dimensions in Paragraph
4.2 and the illustration in FIGURE 7A.
