Section 6 – Installation
Recreational Vehicle Generators
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.
6.6.1 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 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.

6.6.2 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
•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
•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.
6.7ELECTRICAL CONNECTIONS
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
