

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 provided. 
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.

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 
Figure 6.13). Use only manufacturer supplied hard-
ware. Substitution of parts may cause damage to the 
screen or a loose fit to the tailpipe.

•  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.

Be sure to read Section 5.6.

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.
