1.4.2 Air Requirements
The generator set requires correct air flow for cooling
and combustion. The inlet and outlet openings in the
sound enclosure provide the cooling and combustion
air. Figure 1-3 shows the locations of the cooling air
intake and exhaust vents. Inspect the air inlet and outlet
openings inside and outside the housing to ensure that
the air flow is not blocked.

1.5 Power Supply
Power must be supplied from a source that is GFCI
protected to the generator set location for the battery
charger and the optional accessories shown in
Figure 1-5.
Connect power from a circuit on the e ssential loads
panel to the utility power connection points on the
terminal block. The circuit must be backed up by the
generator set. See Section 1.8 and the wiring diagrams
in Section 2 for connection details. See Figure 1-5 for
the power requirements for the battery charger and
accessories.

1.6 Fuel Requirements
The generator set operates using natural gas or LPG
fuel. The generator set is EPA-certified for both natural
gas and LPG fuels.
The fuel system installation must comply with applicable
national, state, and local codes.
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling,
storing, and using fuels.
WARNING
Gas fuel leaks. Explosive fuel vapors can cause severe
injury or death. Fuel leakage can cause an explosion. Check
the LPG vapor or natural gas fuel system for leakage by using
a soap and water solution with the fuel system test pressurized
to 6--8 ounces per square inch (10--14 inches water column).
Do not use a soap solution containing either ammonia or
chlorine because both prevent bubble formation. A successful
test depends on the ability of the solution to bubble.
