Generac 005411-0 Manual De Usuario

The manufacturer 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, enlarge the 

air openings. Never place a unit into service until absolutely certain 

that cooling and ventilation is adequate.

 Gasoline is highly flammable, and its vapors 

are explosive. Comply with all codes, stan-

dards 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 2.10) 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 gasoline 

vapors entering 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, (e) evaporative port. 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.

Either the generator must share the vehicle engine's fuel tank, or a 

separate fuel tank for the generator set must be installed. All fuel 

tanks installed on the vehicle must be constructed, installed and 

restrained so they comply with applicable codes, standards and 

regulations. The generator has an evaporative emissions port to 

evacuate accumulated gasoline vapors when necessary.

If the generator is to share the vehicle engine's tank, separate 

fuel pickup tubes are required for the engine and the generator. 

The manufacturer recommends that the fuel pickup tube be two 

to three inches (51 to 76 mm) shorter than the vehicle engine's 

pickup tube. This prevents the generator from depleting the entire 

fuel supply during prolonged generator operating periods.
Gasoline generators are equipped with an Evaporative Emissions 

Port that may be used in conjunction with a certified fuel system 

where required by law.

 Do NOT tee the generator fuel supply line 

into the vehicle engine fuel supply line. If 

this is done, the generator will be starved of 

fuel when both engines are operating at the 

same time. Also, while the vehicle engine is 

not running, generator operation may drain 

the vehicle engine supply line, making it dif-

ficult to start the vehicle engine.

Those lines used to supply fuel from a tank to the generator must 

comply with applicable codes, standards and regulations. The fol-

lowing general rules apply to rigid fuel lines:

Rigid lines should be of annealed, seamless, drawn aluminum 

• 

or steel.

Lines and fittings must comply with SAE J512F, “Standard 

• 

Automotive Fittings,” or with ANSI B126.26 (latest edition).

Route the fuel line so that at least 2 inches (51 mm) of clear-

• 

ance is maintained between the line and any exhaust system 

parts.

Do not attach electrical wiring to fuel lines. Route the wiring so 

• 

it cannot come into contact with any fuel line.

Route fuel lines so if they leak, fuel does not drip onto any 

• 

electrical or exhaust system parts.

Use nonferrous metal straps without sharp edges to secure 

• 

fuel lines.

Use an approved flexible length of fuel hose between the generator 

fuel inlet connection and rigid fuel lines. This prevents breaking of 

the line caused by vibration, shifting, settling or movement. The 

following rules apply:

The flexible hose must comply with SAE J30R7, “Standard for 

• 

Fuel and Oil Hose.” It must be approved for use with gasoline 

and low permeability.

The hose should be at least 6 inches (152 mm) longer than 

• 

is needed to prevent the hose from rupturing if the generator 

shifts or settles.
