EXHAUST
Vent exhaust gases outside .. Use flexible tubing
between the engine exhaust outlet and rigid piping to
accommodate vibration.
~WARNIN-G-)
'Check exhaust system frequently for leaks.

Be
sure poisonous exhaust gases are piped to
outside. Inhalation of exhaust gases can result
In
serious personal
injury.
Shield'th.e line with fire retardant material. if
it
passes·
through a combustible wall
or
partition. If turns are
necessary, use long sweeping type elbows. Use one
pipe size larger
for
each ten feet in length. Position the
exhaust outlet away from the engine
air
intake.
OIL DRAIN
Extend to suit installation. Oil base has a 1/2 inch
(12.7
mm)
pipe tapped hole.
FUE.L
TANK
If a separate fuel tank is used, install the tank so.the
bottom
is
less than
8feet
(2.5
m)belowthefuel
pump.'
The tank
topmustbe
below fuel pump level to
prevent'
siphoning. Install a shut-off valve at the tank. When
the fuel tank is shared with another engine; use a
separate fuel line
for
each
to
avoid starving the set.
If fuel
lift
must exceed 8 feet (2.5 m), install
an
auxiliary electric fuel pump at the fael supply.
FUEL CONNECTION
Connect the fuel line to the fuel pump inlet. Pump is
threaded
7/16-24 NPTF (American Standard Internal
Tapered Pipe Thread)

WARNING
~
Always use flexible· tubing
bet~een
engine
'.
• and the fuel supply to avoid line failure .and
fuel leaks due to
vibra~lon.
Fuel leaks create tire and explosion
hazards.
For gaseous sets (see Figure 7), check with the local
fuel supplier
for
gas regulations and line pressure.
Provide a manual gas valve. A filter in the lirie may be
necessary. Electric solenoid shut-9ff valves in the
supply line are usually required
for
indoor
automatic
or
remote starting installations. Connect solenoid
wires to .battery ignition circuit to open valve during
running. Install a demand type gas regulator accor-
ding to instructions and position it near the set to aid
starting.
WARNiNG]
Always use flexible tubing between engine
Iw·
_____
._
and the gas demand regulator to avoid line
failure and leaks due to vibration. Gas-Gasoline sets provide a
manual shutoff valve In both fuel supply ilnes. Fuel leaks create fire
and explosion hazards. .
[!ARNING
, Do
not
use galvanized lines, fittings,
or
fuel
tanks In underground portions
of
the fuel
system. Hazardous fuel leaks may
be
caused by· electrolytic
corrosion from moisture and chemicals In the soli (galvanism).
Some safety ordinances prohibit the use
of
galvanized materials In
fuel systems and the use
of
threa.;j
,j
cast Iron fittings as well. Fuel .
leaks create fire and explosion hazards.

GAS FUEL LINE INSTALLATION
ELECTR.lCAl CONNECTIONS
The nameplate on the 'generator set shows the
electrical
output
rating
of
the generator in watts, volts,
..
and
hertz..
The'
wiring diagram, shipped with the
generator set, shows the electrical circuits and con-
nections needed during installation. .
All electrical connections should be done by a qualified serviceman
or
electrician
to
meet the electrical code requirements in your
area.
LOAD WIRES
The control box (junction box) has knock
out
sec-
tions to a:ccommodate load wires. Use flexibie con-
duit
and stranded load wires near the set to.absorb
vibration. Use sufficiently large insulated wires.
Strip.
insulation from wire ends
as
necessary
for
clean
connections. Connect each load wire to the proper
generator output lead inside the set box. Insulate bare
ends of ungrounded wires. Use
bolt
provided on the
control box to connect the generator ground lead and
load wire. Install a fused main switch (or circuit
breaker) between the generator and load. If a test-run
indicates wrong rotation of 3 phase motors
in
the load
circuit, switch the connections at any two generator·
terminals.
Standby: If the installation is
fOJ
standby service,
install a double-throw transfer switch (either manual
or
automatic type) to prevent feeding generator
output
into the normal power source lines and to also
prevent commercial power and generator
output
from
being connected to the load at the same time.
Instructions for connecting
an
automatic load
transfer switch is included with such equipment. See
Figure
8.
Balance
All
loads:
Divide the loads equally between'
output
leads. Current loads for
anyone
output lead'
must not exceed nameplate rating.
