Section 6 – Installation
PRIMEPACT 66G and 66LP Recreational Vehicle Generators
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 unim- proved land, you must provide a spark arrestor. 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.
◆6.6.2 TYPE OF EXHAUST SYSTEM
Two types of exhaust systems for PRIMEPACT series generators are available from Generac. They include the following:
•
•
NOTE:
No matter what type of exhaust kit best fits your recreational vehicle, the mounting base has open- ings for either
◆6.6.3 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 you cannot maintain the
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 com- partment 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 Generac. Using unapproved exhaust mufflers and exhaust sys- tem parts is the responsibility of the person(s) installing such unauthorized parts.
•Do not terminate the exhaust system under any open- ing, window or vent that can be opened or is not per- manently 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 regulations.
6.7ELECTRICAL CONNECTIONS
Be sure to read Section 5.6 on Page 20.
The following general rules apply to electrical connec- tions in a recreational vehicle:
•Qualified electricians who are familiar with applica- ble 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 insu- lative qualities and be properly supported.
•Conduit and wire openings into the generator com- partment (if used) must be
◆6.7.1 ELECTRICAL JUNCTION BOX
Install an approved, square electrical junction box with a blank cover on the interior or exterior wall of the area you plan to install 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.
◆6.7.2 WIRING
•Wiring should be of stranded copper to reduce the chance that vibration may cause breakage.
•Wire gauge size should be large enough to handle at least 115 percent of the installed generator's rated maximum current.
•If neutral conductors are used, they must be the same size as other leg wires.
•Route power supply conductors from generator AC output leads T1 (red), T2 (white), T3 (black) and the green ground wire through approved flexible conduit to the electrical junction box on the compartment wall.
If flexible metal conduit is used between the genera- tor and the compartment junction box, the conduit end that terminates the compartment junction box must be
