Locating The Water
Heater:

The water heater should be located so
that the air supply and exhaust piping
between the water heater and outside
wall/roof are within the minimum and
maximum lengths for horizontal or
vertical venting. (Page 9) See Figure 1
for minimum clearances between the
water heater and any combustible
surfaces.

CAUTION

Do not install the water heater in an
uncontrolled environment where the
condensate will be subject to freezing
temperatures.

NOTE

The water heater must not be installed
on carpeting.

NOTE

The water heater shall be installed such
that the gas ignition system compo-
nents are protected from water
(dripping, spraying, rain, etc.) during
water heater operation and service.

NOTE

All Pulse water heaters 

must

be

installed with vibration isolators.  No
Pulse water heater shall be lagged
directly to the concrete floor due to the
transfer of vibration.  In the box of trim
shipped with each pulse water heater,
Fulton supplies 4 elastomer coated
fiberglass cubes used for vibration
isolation. 

(Figure 2a) For all non-

critical installations these cubes
must be under each foot of the water
heater.

White lines on blocks should be

in “up” position. Flex connectors must
be installed on the water inlet and outlet
lines.  

For installations near

“sensitive” areas such as offices,
classrooms, or hospital rooms,
spring mounts—which fit under the
comer of each water heater—must be
used instead of the cubes,

and flex

connectors must be installed on the
water inlet and outlet lines. Flex
connectors must be installed on the gas
inlet. Spring loaded pipe hangers should
be used on the air inlet, water inlet and
outlet, and the flue gas outlet pipes.
Contact your Fulton Representative for
vibration isolation packages designed
specifically for your application.

Installing Spring
Isolation Mounts

(Figure 2b)

1. 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.
2. Coordinate the location of each isolator.
3. Remove the small cap screw and
washer. Raise the water heater with
jacks or similar tools (Do not attempt to
raise the water heater via one (1) lifting
point, but lift evenly around the
perimeter of the boiler). Slide the spring
isolator under the water heater or
mounting bracket with the bolt head on
the underside of the bracket.
4. Insert the small cap screw through
the bracket and thread into the top of
the leveling bolt and tighten finger tight.
5. Lower the water heater (evenly) onto
the spring isolators. Do not overload any
one isolator and take care not to push
the water heater sideways.
6. Do not attempt to place all the weight
on one spring, but distribute the load
proportionately by adjusting each
isolator in sequence.
7. Continue to adjust each leveling bolt
(in sequence) until the water heater is at
its height. When the water heater is
filled with water, the springs will
compress approximately 1-2".
8. Tighten the small cap screw, thus
securing the spring isolator to the sup-
ported equipment and locking the level-
ing bolt against turning.
9. Do not attempt to move the water
heater laterally while it is supported on
the isolators. If it is necessary to move
the water heater remove the weight
from the isolators by raising the water
heater 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.

Installing Seismic Spring
Isolation Mounts

(Figure 2c)

1. Thread the leveling bolt 

1

/

2

" into the

top of the load cap.
2. 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.
3. Coordinate the location of each isolator.
4. Place a one inch shim next to each

bracket between the water heater and
the housekeeping pad or structural floor.
If an operating clearance of other than
one inch is desired, use an appropriate
size shim.
5. Raise the water heater and slide the
spring isolator under the equipment
mounting bracket. With the leveling nut
and one washer on the under side of the
bracket.
6. Lower the water heater onto the
spring isolators taking care not to
overload any one isolator and taking
care not to push the water heater
sideways.
7. Install second washer and lock nut
one inch down from top of  leveling bolt.
8. Grasp top of leveling bolt with vice
grip and turn leveling nut in a counter-
clockwise rotation until the water heater
just touches the shim. The shim may
now be removed. Proceed with
adjustment of the other three isolators.

9. Tighten the lock nuts on the leveling
bolts, thus bolting the spring to the
water heater and locking the leveling
bolt against turning.
10. Do not attempt to move the isolators
laterally with the weight of the water
heater on them. If it is necessary to move
the boiler, remove the weight from the
isolators by raising the equipment before
moving.
