Exhaust Requirements
WARNING
Carbon monoxide.
Can
cause
fainting, or death.
The
exhaust
leakproof and routinely inspected.
Generator set operation. Carbon monoxide can cause
severe nausea, fainting, or death. Carbon monoxide is an
odorless, colorless, tasteless, nonirritating gas that can cause
death if inhaled for even a short time. Avoid breathing exhaust
fumes when working on or near the generator set. Never
operate the generator set inside a building. Never operate the
generator set where exhaust gas could seep inside or be
drawn into a potentially occupied building through windows, air
intake vents, or other openings.
The exhaust system is complete for generator sets
installed outdoors. Do not install this generator set
indoors.
Figure 1-6 gives the exhaust flow and temperature at
rated load.
The engine exhaust mixes with the
generator set cooling air at the exhaust end of the
enclosure. Mount the generator set so that the hot
exhaust does not blow on plants or other combustible
materials. Maintain the clearances shown in Figure 1-5.

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 1-7 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.
