2.4.8 leakage tests

Do not place the generator into service until the gas

system has been properly tested for leaks. To test the

system, a separate source of 12 volts DC is needed to

open the gaseous fuel solenoid valve.
The leak test must comply fully with NFPA, Paragraph

318. All connections, hoses, valve regulators, fittings,

and other fuel system parts must be tested under

gas or air pressure of not less than 90 psi (620 kPa),

while using soap and water or an equivalent solution

to check for leaks. Other approved methods of testing

for leaks may be used, if appropriate. DO NOT USE

ANY FLAME TO TEST FOR LEAKS.

danger



Gaseous fuel lines between the tank and the

secondary regulator are under a positive pres-

sure (about 11 inches water column). Gas pres-

sure at the outlet side of the secondary regula-

tor, however, is a negative pressure and can

draw flame inside a line or fitting and cause an

explosion.

2.5 exhaust systeM

The generator exhaust system must be safely and

properly installed. Only approved mufflers and other

exhaust system parts must be used. A properly

installed exhaust system must be vapor tight, quiet

and completely safe.

danger



The generator engine gives off DEADLY carbon

monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient con-
centrations, can cause unconsciousness or even
death. Never operate the generator set with
the vehicle inside any garage or other enclosed
area. DO NOT OPERATE THE GENERATOR IF THE
EXHAUST SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOXIDE
POISONING ARE (a) inability to think coher-
ently; (b) vomiting; (c) twitching muscles; (d)
throbbing temples; (e) dizziness; (f) headaches;
(g) weakness; and (h) sleepiness. IF FEELING
ANY OF THESE SYMPTOMS, MOVE INTO FRESH
AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET
MEDICAL HELP. Do not operate the generator
until its exhaust system has been inspected and
properly repaired.





Never tee the generator engine exhaust pipe

into the vehicle engine exhaust piping. This

causes excessive back pressure on the generator

engine. Also, water from one engine can dam-

age the other engine.

2.5.1 spark arrestor

This spark arrestor assembly meets code and stan-

dard requirements of the U.S. Forest Service. Use

only mufflers and parts approved by the manufactur-

er. Any person(s) installing an unapproved muffler, or

an unapproved exhaust system part, or modifying an

exhaust system in any way that might cause a hazard,

is liable for any damage, injury or warranty expense

that might be caused by such unapproved installation

or modification.
Failure to provide and maintain a spark arrestor may

be in violation of the law. If this generator is used on

any forest covered, brush covered or grass covered

unimproved land, provide a spark arrestor. The vehi-

cle owner or operator must maintain this device in

good condition. In the state of California, the preced-

ing is required by law (Section 4442 of the California

Public Resources Code). Other states may have simi-

lar laws. Federal laws apply on federal lands.
When installing/replacing the tailpipe or spark arres-

tor components, verify that the tailpipe has a hole

to securely fasten the spark arrestor components

(see Figures 2.11 and 2.12). Use only manufacturer

supplied hardware. Substitution of parts may cause

damage to the screen or a loose fit to the tailpipe.
