EXECUTION
**************************************************************************
NOTE: Provide an equipment layout on the plans
which provides the clear space for operation and
maintenance in accordance with NFPA 70 and IEEE C2.
Include requirements for a staging/laydown area for
disassembly or removal and replacement of major
parts of the generator set. Additionally, it is
advisable to provide access to remove the unit
and/or major parts of equipment from the room and
building either through doors/passageways or
equipment hatches.

3.1
GENERAL INSTALLATION
Installation shall provide clear space for operation and maintenance in

PIPING INSTALLATION
3.2.1
General
Piping shall be welded. Connections at valves shall be flanged.
Connections at equipment shall be flanged except that connections to the
diesel engine may be threaded if the diesel-engine manufacturer's standard
connection is threaded. Except as otherwise specified, flanged fittings
shall be utilized to allow for complete dismantling and removal of each
piping system from the facility without disconnecting or removing any
portion of any other system's equipment or piping. Connections to all
equipment shall be made with flexible connectors. Pipes extending through
the roof shall be properly flashed. Piping shall be installed clear of
windows, doors, and openings to permit thermal expansion and contraction
without damage to joints or hangers, and with a 13 mm 1/2 inch drain valve
at each low point.

Supports
Hangers, inserts, and supports shall be of sufficient size to accommodate
any insulation and shall conform to MSS SP-58 and MSS SP-69. Supports
shall be spaced not more than 2.1 m 7 feet on center for pipes 50 mm 2
inches in diameter or less, not more than 3.6 m 12 feet on center for pipes
larger than 50 mm 2 inches but no larger than 100 mm 4 inches, and not more
than 5.2 m 17 feet on center for pipes larger than 100 mm 4 inches in
diameter. Supports shall be provided at pipe bends or change of direction.
