Section 2 – Installation

‹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 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 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

Two types of exhaust systems for these generators are available from the manufacturer. They include the following:

•“Out-the-bottom” exhaust system dimensions are 15/16” O.D., model 9742.

•“Out-the-side” exhaust system dimensions are 1- 1/4” O.D., 18 gauge, model 4172.

NOTE:

No matter what type of exhaust kit best fits the recreational vehicle, the mounting base has open- ings for either “bottom-out” or “side-out” exhaust systems. Use the cover plate provided with the generator to cover the opening NOT used.

Recreational Vehicle Generator

•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 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.

2.7ELECTRICAL CONNECTIONS

Be sure to read the "Generator AC Connection System" section.

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.

‹2.6.3 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, 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 tem- perature.

•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.

•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 vapor-sealed to prevent entry of flammable, explosive or poisonous gases into the vehicle.

‹2.7.1 ELECTRICAL JUNCTION BOX

Install an approved, square electrical junction box with a blank cover on the interior or exterior wall of the area planned for installation of the generator (NOT on the generator). Route the generator's AC output leads into this junction box through approved flexible conduit. This is the point of first termination for generator AC output leads.
