Generac Power Systems RV 45 SERIES Owner's Manual page 30

DANGER

The generator engine gives off DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concen-
trations, 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) twitching mus-
cles; (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 genera-
tor engine. Also, water from one engine can
damage the other engine.
2.5.1 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 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, 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 arrestor compo-
nents, 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 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 more than 117° F (65° C)
above the ambient air temperature.
• 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 recircu-
lated.
• 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.
• 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 unauthor-
ized parts.
