IMPACT-36 plus II Recreational Vehicle Generator

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, provide a spark arrestor. The vehi- cle owner or operator must maintain this device in good condition. In the State of California, the preced- ing is required by law (Section 4442 of the California Public Resources Code). Other states may have simi- lar laws. Federal laws apply on federal lands.

◆2.5.2 TYPE OF EXHAUST SYSTEM

•The Impact-36 plus and Impact-34 plus II genera- tors have a configuration for a bottom out exhaust system and is equipped with such an exhaust muf- fler (Figure 2.17).

•Model 004283-0 Exhaust Adapter mates to the O.D. of the spark arrestor outlet of the muffler. It allows the use of 1-1/4” O.D. exhaust pipe to be clamped in place (Figure 2.18).

◆2.5.3 EXHAUST SYSTEM SAFETY

•Maintain a clearance of at least 3 inches (76mm) between exhaust system parts and any com- bustible material (such as wood, felt, cotton, organic fibers or other like material). If the 3-inch clearance cannot be maintained, locate, insulate 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 tempera- ture.

•Extend the exhaust system at least one inch (25mm) 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 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.

•Use exhaust system parts recommended by Generac. 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 which 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.

2.6ELECTRICAL CONNECTIONS

The following general rules apply to electrical con- nections in a recreational vehicle:

•Qualified electricians who are familiar with applic- able codes, standards and regulations should install electrical wiring.

•The wiring should comply with codes, standards and regulations. The National Electric Code (NFPA 70), as well as 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.
