supply, water inlet and water outlet lines. Spring loaded pipe hangers should be used on
the air inlet and the flue gas vent. Contact your Fulton Representative for vibration
isolation packages designed specifically for your application.
Note
For installations near “sensitive” areas such as offices, classrooms, or hospital
rooms, spring mounts-which fit under the corner of each boiler must be used
instead of the cubes.
8. Installing Spring Isolation Mounts
(Figure 2b)
a) Thread the leveling bolt into the top load plate of the spring until the head of the bolt is
within 1/8" of the top load plate of the spring.
b) Coordinate the location of each isolator.
c) Remove the small cap screw and washer. Raise the boiler with jacks or similar tools (Do
not attempt to raise the boiler via one (1) lifting point, but lift evenly around the perimeter
of the boiler). Slide the spring isolator under the boiler or mounting bracket with the bolt
head on the underside of the bracket.
d) Insert the small cap screw through the bracket and thread into the top of the leveling bolt
and tighten finger tight.
e) Lower the boiler (evenly) onto the spring isolators. Do not overload any one isolator and
take care not to push the boiler sideways.
f) Do not attempt to place all the weight on one spring, but distribute the load
proportionately by adjusting each isolator in sequence.
g) Continue to adjust each leveling bolt (in sequence) until the boiler is at its proper height.
When the boiler is filled with water, the springs will compress approximately 1-2".
h) Tighten the small cap screw, thus securing the spring isolator to the supported equipment
and locking the leveling bolt against turning.
