◆ 2.3.4 TESTING THE INSTALLATION

 

Generac recommends testing the installation to be

 

sure adequate cooling airflow is available to the unit

 

before placing the unit into service. If the unit shows

 

signs of overheating, you will need to enlarge the air

 

openings. Never place a unit into service until

 

absolutely certain that cooling and ventilation is ade-

 

quate.

 

NOTE:

 

You must test the installation, especially if you

 

bring in air from below the generator set.

◆2.3.3 COMPENSATING FOR RESTRICTIONS

Such materials as screening, louvers or expanded metal can restrict the free flow of air. Compensate for this restriction by making the actual air opening pro- portionately 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 supplier or manufacturer.

To determine the actual air inlet opening size required, divide 100 square inches by the per- centage of free air inlet area for the material you will use.

For example: If you plan to use screening with an 80 percent free air inlet area, divide 100 by 0.8, which results in 125 square inches. Minimum actual size of air inlet opening in this case is 125 square inches.

2.4GASOLINE FUEL SYSTEM

The installation of a gasoline fuel system (Figure 2.14) 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.

Figure 2.14 – Generator 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.

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.
