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.

2.5.2 EXHAUST SYSTEM SAFETY
• Maintain a clearance of at least 3 inches (76 mm)
between exhaust system parts and any combus-
tible material (such as wood, felt, cotton, organic
fibers or other like material). If the 3-inch (76 mm)
clearance cannot be maintained, locate, insulate or
shield the exhaust part(s) so that the temperature
of any combustible material is not raised more
than 117° F (65° C) above the ambient air tempera-
ture.
• Extend the exhaust system at least 1 inch (25 mm)
past the outer edge of the vehicle. Do not terminate
the exhaust system under the vehicle.
• Terminate the exhaust tailpipe such that exhaust
gases will not be drawn back into the generator
compartment and recirculated.
• If there is any possibility of the tailpipe or muffler
being damaged, protect these damage-prone areas
by means of a protective device (such as a skid
bar).
• Install the generator exhaust system according to
safe automotive practices.
• Use enough exhaust system hangers to prevent any
part of the system from being dislocated.
• Use exhaust system parts recommended by the
manufacturer. Using unapproved exhaust mufflers
and exhaust system parts is the responsibility of
the person(s) installing such unauthorized parts.
• Do not terminate the exhaust system under any
opening, window or vent that can be opened or is
not permanently sealed from the vehicle interior.
• Exhaust piping must be large enough to prevent
excessive back pressure on the generator engine.
• 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 damage the other
engine.
• Plan exhaust system installation carefully. Comply
with all applicable codes, standards and regula-
tions.

ELECTRICAL CONNECTIONS

Be sure to read section "Generator AC Connection
System".
The following general rules apply to electrical connec-
tions in a recreational vehicle:
• Qualified electricians who are familiar with appli-
cable codes, standards and regulations should
install electrical wiring.
• The wiring should comply with codes, standards
and regulations. The National Electrical Code
(NFPA 70), and state and local codes apply.
• Switches and circuit breakers should be of a type
approved for use in recreational vehicles and must
be mounted and installed to prevent damage from
road shock.
