voltage wiring. Do not run Building Management System
(BMS) wiring into the same box as the power.
The Endura cabinet has removable panels to facilitate access.
Do not run conduit through or over access panels.
Adhere to the following when making electrical connections:
1. Install wiring and ground in boiler in accordance with
authority having jurisdiction or in absence of such
requirements National Electrical Code, ANSI/NFPA 70.
2. Connect power to the boiler inside of the customer
connection box using connectors rated for a minimum
of 20 A and are compliant with local electrical codes.
Assembly of Fulton Multi-Skid Systems
Adhere to the following for multi-skid engineered systems:
1. Refer to the Fulton mechanical/electrical drawings
during assembly.
2. Ensure that equipment orientation allows for operation
interface and maintenance.
3. Align the skids as shown on the drawings ensuring that
skid fasteners (skid joint angles) are matched. The skid
joint angles are a matched set and the edges of the
fasteners should be exactly aligned.
NOTE:  Do not bolt the skids to the housekeeping pad/
fl oor until all of the piping has been reassembled and
tightened.
4. Ensure the skids are level and fl at before fastening
the skids together with 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 of the piping is assembled. Note: skids are
leveled at the factory using a laser level.
5. Connect the piping between the skids by matching
the union connections and/or fl ange stamps and
tightening. Refer to the mechanical drawing as
necessary to confi rm location of spool pieces etc. as the
fl ange stamps are shown on the drawing in hexagonal
callouts. The fl ange stamps should matched and
aligned (the fl ange stamps should be directly across
from one another. Rotating a fl ange will result in piping
misalignment). Bolts should be hand tight until all
of the piping is assembled. Refer to the appropriate
instructions to tighten the fl anges to the 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 the skids and
tighten 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 drawings.
9. If a header is supplied, mount the header as shown in
the mechanical drawing.
NOTE:  For piping supplied in sections, make up and
connect hand tight until all sections are in place to
ensure sections align properly. Sections are match
marked for reassembly.
10. Tighten all connections.
11. Pneumatically test the piping (at 15 psig [103 kPa]
maximum) prior to fi lling the systems.
12. Check bolts and connections for tightness after the fi rst
heat up cycle. Retorquing may be required.
