Figure 6-2 gives the exhaust flow and temperature
at
rated load.
Mount the generator set so that the hot
exhaust does not blow on plants or other combustible
materials.

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 6-3 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.

Power Supply
Utility power must be supplied to the generator
set
location. Provide a 110- or 120-volt outlet connected to
the
utility
power
supply
for
the
battery
charger
(standard) and carburetor heater (optional). Figure 6-5
lists the battery charger power requirements.

Fuel System
The generator set operates using natural gas or LP
vapor fuel.
The multi-fuel system allows conversion
from natural gas to LP vapor (or vice-versa) in the field
while maintaining emissions-standard
compliance.
A
trained technician or authorized distributor/dealer
can
convert the fuel system. Generator sets with multi-fuel
systems are CARB- and EPA-certified for both natural
gas and LP vapor fuels.
6.8.1
Fuel Supply
Comply with local, state, and federal codes regarding
the correct storage of fuel. Because of variable climates
and geographical considerations, contact an authorized
service distributor/dealer
for fuel system planning and
installation.
Figure6-1
shows
the
location
of the
fuel
inlet
connection.
Bring the fuel supply lines through the rear
access opening.
Use flexible sections to prevent fuel
line breakage caused by vibration. Remove the housing
end panel and hold the fuel solenoid valve with a wrench
when tightening the fuel connections.
Protect all fuel
lines from machinery or equipment
contact, adverse
weather conditions, and environmental damage.
Verify that the output pressure from the primary gas
utility (or LP tank) pressure regulator is 1.7-2.7 kPa
(7-11 in. water column) and that the utility gas meter
flow rate is sufficient to supply the generator set plus all
other gas-consumingappliances.

flow rate required for the generator set. Figure 6-6 lists
