i) Do not attempt to move the boiler laterally while it is supported on the isolators. If it is
necessary to move the boiler remove the weight from the isolators by raising the boiler
before moving. Failure to follow this procedure could result in bent or broken leveling
bolts or springs, or damage to the neoprene bottom spring cap.
9. Installing Seismic Spring Isolation Mounts
(Figure 2c)
a) Thread the leveling bolt 1/2" into the top of the load cap.
b) Remove the lock nut and one washer from the top of the leveling bolt. Locate leveling nut
as far down on leveling bolt as it will travel.
c) Coordinate the location of each isolator.
d) Place a one inch shim next to each bracket between the boiler and the housekeeping pad
or structural floor. If an operating clearance of other than one inch is desired, use an
appropriate size shim.
e) Raise the boiler and slide the spring isolator under the equipment mounting bracket with
the leveling nut and one washer on the under side of the bracket.
f) Lower the boiler onto the spring isolators taking care not to overload any one isolator and
taking care not to push the boiler sideways.
g) Install second washer and lock nut one inch down from top of leveling bolt.
h) Grasp top of leveling bolt with vice grip and turn leveling nut in a counter-clockwise
rotation until the boiler just touches the shim. The shim may now be removed. Proceed
with adjustment of the other three isolators.
i) Tighten the lock nuts on the leveling bolts, thus bolting the spring to the boiler and locking
the leveling bolt against turning.
