2.3 COOLING AND VENTILATING AIR
It is absolutely essential that an adequate flow of
air for cooling, ventilating and engine combustion
be supplied to the generator set. Without sufficient
airflow, the engine/generator quickly overheats. Such
overheating can cause serious operating difficulties
and also may cause fire and personal injury. The
installer must make sure that sufficient air is avail-
able to the generator for cooling, ventilating and
combustion. The installer also must provide for a
path for exhausting the cooling air to the exterior of a
compartment, if so equipped.
DANGER

Never use discharged cooling air for heating or
permit such air to enter the vehicle interior. This
air contains deadly carbon monoxide gas and
other poisonous, flammable or explosive gases.
2.3.1 GENERATOR AIRFLOW
Engine operation drives cooling fans for the two-stage
cooling air system. A pressure fan draws cooling air
into the bottom right side of the generator (Figure 2.9).
This airflow cools the engine/generator and electronic
components. The second part of the cooling system, a
suction fan, draws air that is heated from a hot engine
into a collector compartment at the left side of the unit.
This heated air (although cooler than exhaust muffler)
is then deflected out the bottom toward the ground.


2.3.2 TESTING THE INSTALLATION
The manufacturer recommends testing the installa-
tion to be sure adequate cooling airflow is available to
the unit before placing the unit into service. If the unit
shows signs of overheating, enlarge the air openings.
Never place a unit into service until absolutely certain
that cooling and ventilation is adequate.
NOTE:
Test the installation, especially if bringing in air
from below the generator set.
2.4 GASOLINE FUEL SYSTEM
The installation of a gasoline fuel system (Figure
2.10) for a recreational vehicle generator set must
comply with applicable codes, standards and regula-
tions. The entire fuel system must be completely free
of leaks. There must be no possibility of gasoline
vapors entering the vehicle interior.

DANGER

Gasoline is highly flammable, and its vapors are
explosive. Comply with all codes, standards and
regulations pertaining to gasoline fuel systems
used in recreational vehicle generators. Properly
install and maintain the fuel system and keep it
entirely free of leaks. Gasoline vapors must not
enter the vehicle interior.
Factory installed generator fuel system components
include (a) fuel filter, (b) 12-volt DC electric pump,
(c) engine carburetor, and (d) interconnecting lines
and fittings. Connect a fuel supply line to the fuel
filter inlet. Use a flexible length of approved fuel hose
between the fuel filter inlet connection and rigid fuel
lines.
