WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Once the system has been fi lled,
any modifi cation to the tank or
connected piping requires purging
of the work area to prevent ignition
of potentially fl ammable vapors.
Consult factory prior to beginning
work. Consult Material Safety Data
Sheet (MSDS) for your thermal fl uid
for fl ammability limits.

CAUTION
Non-code tanks cannot be pressurized
over 15 psig.
If the deaerator/thermal buff er/
expansion tank is located outdoors, a
nitrogen blanket is required.
4. Ensure the skids are leveled and fasten the skids together using the
supplied bolts. The skids should be leveled front to back, side to side and
corner to corner. Failure to properly level the skids will result in piping
misalignment. A level or laser level should be used to verify skid alignment
(when a standard level is used, the length should be appropriate for the
skid) If assembling multi-component support stands, attach sections using
the supplied bolts through the tank frame mounting plates. These should
be hand tight until all piping has been assembled and tightened.
5. Connect the piping between skids by matching the union connections
and/or fl ange stamps and tightening. Refer to the appropriate instructions
to tighten the fl anges and required torque specifi cations. Support pipe
runs as required.
6. Ensure that a low point drain is installed in the piping.
7. Connect the conduit runs between skids and tighten the conduit
connectors.
8. Locate the supplied wiring for the equipment and pull wiring through
the appropriate conduit runs. Electrical wires are labeled for easy landing.
Connect all wiring per the Fulton supplied electrical drawing. If a header is
supplied, mount the header as shown in the mechanical drawing.
NOTE:

For piping supplied in sections it should be made up and connected hand
tight until all sections are in place to ensure sections align properly. Sections are
match marked for reassembly.
9. Tighten all connections.
10. Pneumatically test the piping (at 15 psig maximum) prior to fi lling the
system.
11. Check bolts and connections for tightness after the fi rst heat up cycle.
Retorquing may be required.
Stack and Flue
An appropriately sized stack should be connected to the fl ue gas outlet at the
heater. The proper fl ue size and draft control is most important for proper burner
operation. The fl ue must be as large or larger than the outlet on the vessel.
Avoid fl ue piping and elbows by placing the equipment as close as possible to
the chimney.
Adhere to the following for stack and fl ue installation:
1. Ensure the stack is at least the same diameter as the fl ue gas outlet.
2. Ensure the stack rises continuously to the connection at the chimney and
contains no more than two bends at 45 degree angles or less. If required,
as a result of space limitations, one 90 degree elbow (or tee) can be fi tted
at the back of the vessel.
3. Ensure 2 feet (0.6 m) of straight fl ue before any change in direction, fi tting
