COMPENSATING FOR RESTRICTIONS
Materials, such as, screening, louvers, or expanded
metal, can restrict the free flow of air. Compensate
for this restriction by making the actual air opening
proportionately larger.
Some materials may offer only a 60 percent "free air
inlet area." Other more efficient materials may pro-
vide up to a 90 percent free air inlet area. The per-
centage of free air inlet opening is usually available
from the material's supplier or manufacturer.
To determine the actual air inlet opening size
required, divide 150 square inches (975 cm 2 ) by
the percentage of free air inlet area for the mate-
rial being used.
For example: If planning to use screening with an 80
percent free air inlet area, divide 150 (975) by 0.8,
which results in 187.5 square inches (1,218.75 cm2).
Minimum actual size of air inlet opening in this case
is 187.5 square inches (1,218.75 cm2).

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 open-
ings. Never place a unit into service until absolutely
certain that cooling and ventilation is adequate.
The installation must be tested, especially if bring-
ing in air from below the generator set.
2.4
DIESEL FUEL SYSTEM
The installation of a diesel fuel system (Figure 2.12)
for a recreational vehicle generator set must comply
with applicable codes, standards, and regulations.
The entire fuel system must be completely free of
leaks. There must be no possibility of fuel vapors
entering the vehicle interior.
Figure 2.12 – Generator Fuel System
DANGER
All fuel types are potentially FLAMMABLE and/
or EXPLOSIVE and should be handled with care.
Comply with all laws regulating the storage and
handling of fuels. Properly install and maintain
the fuel system, and keep it entirely free of
leaks. Fuel vapors must not enter the vehicle
interior.
