6.3.2 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:
The installation must be tested, especially if bring-
ing in air from below the generator set.
6.4 GASOLINE FUEL SYSTEM
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.
The installation of a gasoline fuel system (Figure
6.10) 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.
