2.6.1 MUFFLERS AND SPARK ARRESTORS
This muffler meets code and standard requirements
of the U.S. Forest Service. Use only mufflers and
parts approved by the manufacturer. 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 modi-
fication.
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, a spark arrestor must be installed.
The vehicle owner or operator must maintain this
device in good condition. In the state of California,
the preceding is required by law (Section 4442 of
the California Public Resources Code). Other states
may have similar laws. Federal laws apply on federal
lands.
2.6.2 TYPE OF EXHAUST SYSTEM
Two types of exhaust systems for these generators
are available from the manufacturer. They include
the following:
“Out-the-bottom” exhaust system dimensions are
15/16” O.D., model 9742.
“Out-the-side” exhaust system dimensions are 1-
1/4” O.D., 18 gauge, model 4172.
NOTE:
No matter what type of exhaust kit best fits the
recreational vehicle, the mounting base has open-
ings for either “bottom-out” or “side-out” exhaust
systems. Use the cover plate provided with the
generator to cover the opening NOT used.
2.6.3 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 tem-
perature.
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.
2.7 ELECTRICAL CONNECTIONS
Be sure to read the "Generator AC Connection
System" section.
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.
Wiring must be of adequate size, have approved
insulative qualities and be properly supported.
Conduit and wire openings into the generator com-
partment (if used) must be vapor-sealed to prevent
entry of flammable, explosive or poisonous gases
into the vehicle.
2.7.1 ELECTRICAL JUNCTION BOX
Install an approved, square electrical junction box
with a blank cover on the interior or exterior wall
of the area planned for installation of the generator
(NOT on the generator). Route the generator's AC
output leads into this junction box through approved
flexible conduit. This is the point of first termination
for generator AC output leads.
