Hanging the
Heater
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.
The heater has four-point suspension. Suspension point dimensions are
shown in
FIGURE 2
, page 7. A 3/8”-16 threaded nut retainer is located at
each suspension point (
FIGURE 4A
).
If ordered with swivel connectors, Option CK10, for 1” pipe attach the swiv-
els at the threaded nut retainers. Suspend with 1” pipes (
FIGURE 4B
).
Before suspending the heater, check the supporting structure to be used
to verify that it has sufficient load-carrying capacity to support the weight
of the unit.

pressure. Adjusting the valve outlet pressure is done after the heater is in
operation; follow the instructions in Paragraph 7.1.3. Capacities and inputs
for derated units are also listed in Paragraph 7.1.3.
