2.5 EXHAUST SYSTEM
The generator exhaust system must be safely and properly
installed. Only approved exhaust system parts must be used. A
properly installed exhaust system must be vapor-tight, quiet, and
completely safe.

The generator engine gives off DEADLY
carbon monoxide gas through its exhaust
system. This dangerous gas, if breathed
in sufficient concentrations, 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 coherently, (b) vomiting, (c) twitch-
ing 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 gen-
erator engine. Also, water from one engine
can damage the other engine.
2.5.1 MUFFLER AND SPARK ARRESTOR
The exhaust muffler supplied with this unit is a spark arrestor type
that meets code and standard requirements of the U.S. Forest
Service. 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 unap-
proved installation or modification.
2.5.2 EXHAUST SYSTEM SAFETY
• Maintain a clearance of at least 3 inches (76 mm) between
exhaust system parts and any combustible material (such as,
wood, felt, cotton, organic fibers, or other like material). If the
3-inch (76 mm) clearance cannot be maintained, locate, insu-
late, or shield the exhaust part(s) so that the temperature of any
combustible material is not raised to more than 117° F (65° C)
above the ambient air temperature.
• Terminate the exhaust tailpipe at least 3 feet (91 cm) from the
vehicle’s fuel filler cap and at least 2 inches (51 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 recircu-
lated.
• Fuel and oil must NOT be able to drip onto any exhaust system
part.

• If there is any possibility of the tailpipe or muffler being dam-
aged, protect these damage-prone areas by means of a protec-
tive device (such as, a skid bar).
• Install the generator exhaust system according to safe automo-
tive practices.
• Use enough exhaust system hangers to prevent any part of the
system from being dislocated.
