Section 2 – Installation
Recreational Vehicle Generator
DANGER 
Gaseous fuel lines between the tank and the secondary regulator are under a positive pres- sure (about 11 inches water column). Gas pres- sure at the outlet side of the secondary regula- tor, however, is a negative pressure and can draw flame inside a line or fitting and cause an explosion.
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
2.6EXHAUST SYSTEM
The generator exhaust system must be safely and properly installed. Only approved mufflers and other exhaust system parts must be used. A properly installed exhaust system 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 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 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 damage the other engine.
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 modification.
Two types of exhaust systems for these generators are available from the manufacturer. They include the following:
•
•
NOTE:
No matter what type of exhaust kit best fits the recreational vehicle, the mounting base has openings for either “bottom- out” or
2.6.3 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
•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
•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.
•Do not terminate the exhaust system under any opening, win- dow 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.
