EXHAUST SYSTEM
The generator exhaust system must be safely and
properly installed. Only approved exhaust system
parts must be used. A properly installed exhaust sys-
tem 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.

MUFFLER AND SPARK ARRESTOR
The exhaust muffler supplied with this unit is a spark
arrestor type that meets code and standard require-
ments 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 unapproved installation or modi-
fication.

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, insu-
late, or shield the exhaust part(s) so that the tem-
perature 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 recirculated.
• Fuel and oil must NOT be able to drip onto any
exhaust system part.

TAILPIPE MUST EXTEND 2 INCHES
BEYOND THE COACH BODYWORK
• 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.
