Assembly of Fulton Multi-Skid
Engineered Systems
Adhere to the following:
1. Refer to the Fulton mechanical/electrical
drawings during assembly.
2. Ensure that the equipment orientation allows for
operation interface and maintenance.
3. Align the skids as shown in the drawings,
ensuring that the skid fasteners are matched
and that skids are fully supported on a non-
combustable base.
4. Ensure the skids are leveled and fully supported
on a non-combustable base. 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. Fasten the skids together
using the supplied bolts. 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 flange stamps.
Refer to the appropriate instructions to tighten
the flanges and required torque specifications.
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.
9. Connect all wiring per the Fulton supplied
electrical drawing.
10. If a steam header is supplied, mount the header
as shown in the mechanical drawing.

VSRT_IOM_2018-1213
Note: If header is supplied in sections it should be
connected hand tight until all sections are in place to
ensure sections align properly. Sections are match
marked for reassembly.
11. Tighten all connections.
12. Pneumatically test the piping prior to
commissioning the system.
13. Check bolts and connections for tightness after
the first heat up cycle. Retorquing may be
required.
Stack & Flue Connections
Adhere to the following for stack and flue connections:
1. An appropriately-sized stack should be connected
to the flue gas outlet at the boiler. The proper flue
size and draft control is most important for proper
burner operation. The flue must be as large or
larger than the outlet on the vessel. Avoid long
flue piping and too many elbows by placing the
equipment as close as possible to the chimney.
2. The stack should rise continuously to the
connection at the chimney and should contain 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 fitted at the back of
the vessel.
3. There should be two feet of straight, horizontal
flue before any change in direction, fitting or draft
regulator. This is to prevent potential pilot or
main flame failures due to back pressure build up
during ignition.
4. Any alternative stack arrangement must supply
the following draft:
» Model ICS (FB-A), ICX (FB-F), ICT (FB-T), and
VMP boilers must supply a draft condition
of -0.02" w.c. to -0.04'" w.c. standing hot and
-0.04" w.c. to -0.08" w.c. running hot.
» Model VSRT must supply a draft condition of
-0.25" w.c. to + 1.50" w.c draft at the boiler.
» Positive pressure draft requires a CAT 3 stack.
