 these
machines. Ensure all steps are taken to

render the machine safe before attempting to
work on the generator.

Parts of the generator are rotating and/or hot
 during
operation. Exercise care near running
generators.

 General Hazards 
• For safety reasons, the manufacturer recommends
that the installation, initial start-up and maintenance of this equipment is carried out by an
Authorized Service Dealer.



• The generator engine releases DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentrations, 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) nausea,
(c) vomiting, (d) twitching muscles, (e) throbbing
temples, (f) dizziness, (g) headaches, (h) weakness, and (i) sleepiness. IF EXPERIENCING ANY
OF THESE SYMPTOMS, MOVE INTO FRESH AIR
IMMEDIATELY. IF SYMPTOMS PERSIST, GET
MEDICAL HELP. Shut down the generator and
do not operate it until it has been inspected and
repaired.
• Never sleep in the vehicle while the genset is running unless the vehicle has a working carbon
monoxide detector. The exhaust system must be
installed in accordance with the genset installation
manual. Make sure there is ample fresh air when
operating the genset in a confined area.
• The engine exhaust fumes contain carbon monoxide, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. This exhaust
system must be installed properly, in strict compliance with applicable codes and standards.
Following installation, do nothing that might render the system unsafe or in noncompliance with
such codes and standards. The generator compartment must be completely vapor sealed from
the vehicle interior. There must be no possibility of

1.2 GENERATOR APPLICABILITY

These generators have been designed and manufactured for supplying electrical power for recreational
vehicles. Do not modify the generator or use it for
any application other than for what it was designed.
If there are any questions pertaining to its application, write or call the factory. Do not use the unit until
advised by a competent authority.

danger
For fire safety, the generator must have been
 properly
installed in compliance with ANSI

1.4 Generator ac
connection system

This generator set is equipped with dual stator AC
power windings. These two-stator windings supply electrical power to customer electrical loads by
means of a two-wire connection system. Note, however, that the neutral is bonded to the frame of the
engine-generator.
The generator may have been installed so that it powers 120-volt AC loads (Figure 1.1).

Figure 1.1 – Connections for 120 Volts Only

119.2-1975/NFPA 501C-1974, “Standard for
Recreational Vehicles, Part III – Installation of
Electrical Systems.” The generator also must
have been installed in strict compliance with the
manufacturer’s detailed installation instructions.
After installation, do nothing that might render the unit in noncompliance with such codes,
standards and instructions.
Use this generator to supply electrical power for
operating 120-volt, single-phase, 60 Hertz, AC electrical loads. These loads can require up to 3,400
watts (3.4 kW) of power, but cannot exceed 28.3 AC
amperes of current at 120 volts.



o not overload the generator. Some installaD
tions may require that electrical loads be alternated to avoid overloading. Applying excessively high electrical loads may damage the generator and may shorten its life. Add up the rated
watts of all electrical lighting, appliance, tool
and motor loads the generator will power at
one time. This total should not be greater than
the wattage capacity of the generator. If an
electrical device nameplate gives only volts and
amps, multiply volts times amps to obtain watts
(volts x amps = watts). Some electric motors
require more watts of power (or amps of current) for starting than for continuous operation.

1.3 SAFETY

Before attempting to use the generator set, carefully read the “Safety Rules” section of this manual.
Comply strictly with these rules to prevent accidents
and damage to equipment and/or property. We suggest copying and posting the “Safety Rules” in potential hazard areas of the vehicle. Stress safety to all
operators and potential operators of this equipment.

28.3 AMP

1.5 Specifications
 1.5.1 Fuel Requirements
These generators are equipped with a liquefied petroleum (LP) gas fuel system. LP gas is usually aupplied
as a liquid in pressure tanks.
These generators require a “vapor withdrawal” type
fuel system. This type of gaseous fuel system uses the
vapors forming above the liquid fuel in the storage
tank. Air temperature around the storage tank must
be high enough to sustain adequate fuel vaporization.
In colder climates, use of an independent heat source
may be needed to be sure the fuel sufficiently vaporizes in the storage tank.
LP gas may consist of propane, butane, or a mixture
of the two gases. Propane vaporizes at tempertures as
low as -20°F (-29°C), but butane returns to its liquid
state when the temperature drops below about 32°F
(0°C). For that reason, a higher ratio of propane is
desired in the gas mixure when temperatures drop
below freezing.

at all times.

2.4 starting the generator
NOTE:

Read the vehicle manufacturer’s instructions.
The owner/operator should become familiar with
the vehicle in which this generator is installed.
Differences exist between vehicles. For example,
some vehicles may use a transfer switch to isolate
dockside power from the generator, while other
vehicles may use an isolating receptacle. Some
vehicles may be equipped with a DC converter,
which allows the generator to power certain DC
lighting and other DC loads.
To start the generator from either the generator control panel or from the optional remote panel, proceed
as follows:
1. Turn OFF electrical loads using the means provided in the vehicle (such as a main line circuit
breaker or transfer switch).

Section 2 – Operation

 2.6.1 letting the engine stabilize
The generator supplies correct rated voltage only at
the proper governed speed. Some electrical appliances may be extremely sensitive to voltage. Incorrect
voltages can damage such appliances.

If electrical loads are applied at reduced operating
speeds, such loads imposed on the engine when sufficient power is not available may shorten engine life.
Never turn ON electrical loads until after the generator engine has started and stabilized at no-load.

2.7 do not overload the
generator

Read the rated wattage/amperage capacity of the generator on the generator data label (see Section 1.1).
Applying electrical loads in excess of the unit’s rated
capacity will cause the engine/generator to automatically shut down.
To avoid overloading, add up the wattage of all connected electrical lighting, appliance, tool and motor
loads. This total should not be greater than the
generator’s rated wattage capacity.
• Most lighting, appliance, tool and motor loads
indicate their required watts on their nameplate or
data plate. For light bulbs, simply note the wattage
rating of the bulb.
• If a load does not show its rated wattage, multiply
that load’s rated VOLTS times AMPS to obtain
WATTS.
• Induction type motors (such as those that run the
vehicle’s furnace fan, refrigerator, air conditioner,
etc.) need about 2-1/2 time more watts of power for
starting than for running (for a few seconds during
motor starting). Be sure to allow for this when connecting electrical loads to the generator. First, figure the watts needed to start electric motors in the
system. To that figure, add the running wattages of
other items that will be operated by the generator.
• Do not apply heavy electrical loads for the first two
or three hours of operation.

2.8 Protection Systems
 2.8.1 Low Oil Pressure Switch
This switch (Figure 2.2) has normally closed (N.C.)
contacts that are held open by engine oil pressure during cranking and operating. Should oil pressure drop
below a preset level, switch contacts close, and the
engine automatically shuts down. The unit should not
be restarted until oil is added.

 2.8.2 High Temperature Switch
This switch (Figure 2.2), which has normally open
(N.O.) contacts, is mounted near the oil filter. The
contacts close if the temperature should exceed
approximately 284º F (140º C), initiating an engine
shutdown.

Switch

The voltage regulator also incorporates a “voltage
surge protection circuit.” This circuit prevents troublesome surges in the generator AC output voltage.
Voltage surge is a common cause of damage to electronic equipment.

 2.8.3 field boost
The Controller Circuit Board houses a field boost
diode and resistor that are not part of the automatic
choke circuit. These two components are part of
a “field boost” circuit (Figure 2.3). During engine
cranking only, a positive DC (battery) voltage is
delivered through the diode, resistor, brushes and
slip rings, to the generator rotor. Application of this
voltage to the rotor “flashes the field” whenever it is
started. Flashing of the field each time the generator
starts makes sure that a sufficiently strong magnetic
field is available to produce “pickup” voltage in the
stator windings.

Figure 2.3 – Field Boost Circuit

2.9 Additional Information
 2.9.1 25-HOUR BREAK-IN PERIOD
The first 25 hours of operation is the break-in period
for the generator. Properly breaking in the generator is essential to minimize fuel consumption and
provide maximum engine performance. During this
25-hour break-in period, follow this procedure:
• Run the unit at varying electrical loads to help seat
the engine piston rings properly.
• Check the engine oil level frequently. Add oil if
needed. It is normal for the generator engine to
consume more oil than is normal until the piston
rings have properly seated.
• For the 75-hour operation following the break-in
period, avoid light electrical loads. Load the generator at 50 percent (or more) of its rated wattage capacity. Repeated light loads during these 75
hours can cause improper seating of engine piston
rings, resulting in blowby and high oil consumption.
• After operating the unit for 25 hours, complete the
tasks recommended under Section 2.10.2.

 2.9.2 25-HOUR CHECK-UP
 2.8.4 overvoltage protection
A solid-state voltage regulator (Figure 2.4) controls
the generator’s AC output voltage. This regulator supplies an excitation current to the rotor. By regulating
the rotor’s excitation current, the strength of its magnetic field is regulated and, in turn, the voltage delivered to connected electrical loads is controlled. When
the AC frequency is 60 Hertz, voltage is regulated at
120 volts (voltage-to-frequency ratio is 2-to-1).

After the 25-hour break-in period, contact an
Authorized Service Dealer for the following maintenance. The vehicle owner is responsible for any
charges:
• Change the engine crankcase oil and oil filter.
• Check the oil level.
• Inspect the cooling and ventilation openings.
• Check the engine carburetor adjustments.
• Check the engine ignition system.
• Inspect the entire electrical system.
• Inspect the engine exhaust system.

Section 3 – Maintenance
Recreational Vehicle Generator

 2.9.3 attention required after
submersion
If the recreational vehicle generator has been submerged in water, it must not be started and operated. Following any submersion in water, have an
Authorized Service Dealer thoroughly clean and dry
the generator.

 2.9.4 OPERATion in high grass orbrush
Never operate the generator while the vehicle is
parked over high grass, weeds, brush, leaves or any
other combustible substance. Such materials can
ignite and burn from the heat of the exhaust system.
The generator exhaust system becomes extremely
hot during operation and remains hot for a long time
after it has shut down.

3.1 CHECKING the ENGINE OIL
LEVEL

For oil capacities and requirements, see “Engine
Oil Requirements,” Section 1.5.4. Check the engine
crankcase oil level at least every eight hours of operation, or before using it. To check the engine oil level,
proceed as follows (see Figure 3.1):
1. Be sure the generator is as level as possible.
2. Remove the dipstick and wipe it dry with a clean,
lint-free cloth.
3. Install and tighten the dipstick cap; then, remove
it again. The oil level should be at the dipstick
“Full” mark.
4. If necessary, remove the oil fill cap on the rocker
cover and slowly add oil until it reaches the dipstick “Full” mark. DO NOT FILL ABOVE THE
“FULL” MARK.

 2.9.5 effects of moisture and dirt
Keep the generator set as clean and dry as possible.
Protect the unit against excessive dust, dirt, corrosive vapors, road splash, etc. Permitting dirt and
moisture to accumulate on generator windings will
have an adverse effect on the insulation resistance of
those windings.
When moisture is allowed to remain in contact with
windings, some of the moisture will be retained in
voids and cracks in the insulation. This causes a
reduced insulation resistance and will eventually
cause problems. Dirt will make the problem worse,
since dirt tends to hold moisture in contact with
windings. Salt (as from sea air) also will worsen the
problem since it tends to absorb moisture from the
air. Salt and moisture, when combined, form a good
electrical conductor.

Never operate the engine with the oil level
 below
the “Add” mark on the dipstick. Doing

this could damage the engine.
5. Install and tighten the oil fill cap and the dipstick
before operating the engine.

3.2 CHANGing the ENGINE OIL
and/or Oil Filter

• Change the engine oil after the first 25 hours
of operation (after the 25-hour break-in period, see Section 2.10.1). Thereafter, change the
oil every 100 operating hours. Change the oil more
frequently if operating consistently under heavy
load or at high ambient temperatures.

• Change the engine oil filter after the first 25 hours
of operation, and every 100 operating hours thereafter.
To change the oil and/or oil filter, proceed as
follows (see Figure 3.1):
1. Run the engine until it is thoroughly warmed up
(at least five minutes) then shut OFF the engine.
2. Immediately after the engine shuts OFF, pull the
oil drain cover free of the base. Remove the plug
from the tube with a 5/16” allen wrench and drain
the oil into a suitable container. Loosening the oil
fill cap will allow the crankcase to drain faster.
3. After the oil has drained, replace the plug onto
the end of the oil drain tube. Retain the cover in
the base.
4. With the oil drained, remove the old oil filter by
turning it counterclockwise. Place a towel underneath to catch excess oil.
5. Apply a light coating of clean engine oil to the gasket of the new filter. Fill the filter until saturated
with clean oil.
6. Screw the new filter on by hand until its gasket
lightly contacts the oil filter adapter. Then, tighten
the filter an additional 3/4 to one turn.
7. Remove the dipstick and wipe it dry with a clean,
lint-free cloth. This will be used later to check the
oil level.
8. Remove the oil fill cap on the oil fill tube and
slowly add the proper type and amount of recommended oil (see Section 1.5.4). Periodically use
the dipstick to check the oil level and continue to
fill the crankcase until the oil reaches the dipstick
“Full” mark. DO NOT FILL ABOVE THE “FULL”
MARK.
9. Install and tighten the oil fill cap and the dipstick
before operating the engine.
10. Start the engine and check for leaks.
NOTE:
Check the oil level and fill to the “FULL” mark
after checking for leaks. The filter will retain some
oil.

3.3 Maintaining The ENGINE
AIR CLEANER
 3.3.1 cleaning the Foam Precleaner
Clean and re-oil the foam precleaner every three
months or every 25 hours of operation, whichever

8. Install the cover, foam precleaner and paper filter.
9. Tighten the two screws to retain the filter in place.

Figure 3.2 – Engine Air Cleaner

 3.3.2 cleaning or replacing the paper
filter
Once each year or every 100 hours of operation
(whichever comes first), clean or replace the paper
filter. The new replacement filter must be flame
retardant. Service the paper filter more frequently if
operating the generator in extremely dusty or dirty
conditions. Use the following procedure (Figure 3.2):
1. Follow steps 1-3 in Section 3.3.1; service the
foam precleaner if necessary.
2. Remove the paper filter.
3. Clean the air filter by tapping it gently on a solid
surface. If the filter is too dirty, replace it with a
new one. Dispose of the old filter properly.
4. Clean the air cleaner cover then reassemble
following steps 7-9 in Section 3.3.1.

3.4 Clean air intake

Clean all foreign material from the air intake (Figure
3.3) at least once every 100 hours of operation. Clean
more often if necessary.
Inspect the area around the generator exhaust muffler periodically and remove all grass, leaves, dirt,
etc., from this area.

1. Turn the two screws counterclockwise to loosen.
2. Remove the cover, foam precleaner and paper filter.

3.5 Checking the Engine Spark
Plug

Clean the spark plug and reset the spark plug gap
every 100 hours of operation.
1. Clean the area around the base of the spark plug
to keep dirt and debris out of the engine. Remove
the spark plug and check the condition. Replace
the spark plug if worn or if reuse is questionable.
2. Clean spark plug by scraping or washing using a
wire brush and commercial solvent. Do not blast
the spark plug to clean.
3. Check the spark plug gap using a wire feeler
gauge. Adjust the gap to 0.030 inch (0.76 mm)
by carefully bending the ground electrode
(Figure 3.4).

3.7 CLEANING THE GENERATOR

Keep the generator set as clean and dry as possible.
Protect the unit against excessive dust, dirt, corrosive
vapors, road splash, etc. Permitting dirt and moisture to accumulate on generator windings will have
an adverse effect on the insulation resistance of those
windings.

Sparking can occur if the wire terminal does
not fit firmly on the spark plug terminal end. If
necessary, re-form the wire terminal to obtain
a tight fit.

When moisture is allowed to remain in contact with
windings, some of the moisture will be retained in
voids and cracks in the insulation. This causes a
reduced insulation resistance and will eventually
cause problems. Dirt will make the problem worse,
since dirt tends to hold moisture in contact with
windings. Salt (as from sea air) also will worsen the
problem since it tends to absorb moisture from the
air. Salt and moisture, when combined, form a good
electrical conductor which can be damaging to the
generator windings.

Do NOT use a forceful spray of water to clean
 the
generator. Water will enter the generator

interior and cause problems, and may also contaminate the generator fuel system.

3.8 Battery Maintenance

All lead-acid batteries will discharge when not in
use. The generator battery should be inspected as
follows:

 3.8.1 Weekly
• Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
• Check the battery fluid level of unsealed batteries
and, if necessary, fill with Distilled Water Only. Do
not use tap water in batteries.

• Disconnect any charging source prior to connecting

9. The generator is now ready for service.

3.12 ADJUSTING VALVE CLEARANCE

After the first 50 hours of operation, adjust the valve
clearance in the engine.
When adjusting valve clearance, the engine should be
at room temperature and the piston should be at Top
Dead Center (TDC) of its compression stroke (both
valves closed). Correct clearance is 0.001-0.003 inch
(0.03-0.07mm). Adjust valve clearance as follows:
1. Loosen the rocker arm jam nut. Use an allen
wrench to turn the pivot ball stud while checking
clearance between the rocker arm and the valve
stem with a feeler gauge (Figure 3.6).

and/or equipment from other suppliers.
The manufacturer cannot anticipate every possible
circumstance that might involve a hazard. The warnings in this manual, and on tags and decals affixed
to the unit, are, therefore, not all inclusive. If using
a procedure, work method or operating technique
the manufacturer does not specifically recommend,
ensure that it is safe for others. Also make sure the
procedure, work method or operating technique utilized does not render the generator unsafe.
Information, illustrations, specifications, etc., contained in these Installation Instructions are based on
the latest information available at the time of publication. Every effort has been expended to be sure that
such data is both accurate and current. However, the
manufacturer reserves the right to change, alter or
otherwise improve this product at any time without
prior notice.

Potentially lethal voltages are generated by
 these
machines. Ensure all steps are taken to

render the machine safe before attempting to
work on the generator.

Parts of the generator are rotating and/or hot
 during
operation. Exercise care near running
generators.



 General Hazards 
• For safety reasons, the manufacturer recommends
that the installation, initial start-up and maintenance of this equipment is carried out by an
Authorized Service Dealer.
• The engine exhaust fumes contain carbon monoxide, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. This exhaust
system must be installed properly, in strict compliance with applicable codes and standards.
Following installation, do nothing that might render the system unsafe or in noncompliance with
such codes and standards. The generator compartment must be completely vapor sealed from
the vehicle interior. There must be no possibility of
exhaust fumes entering the vehicle interior. Never
operate this equipment with a leaking or defective
exhaust system.
• Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit
is operating.
• Adequate, unobstructed flow of cooling and ventilating air is critical to correct generator operation and is required to expel toxic fumes and fuel
vapors from the generator compartment. Without
sufficient cooling airflow, the engine/generator
quickly overheats, which causes serious damage
to the generator. Do not alter the installation or
permit even partial blockage of ventilation provisions, as this can seriously affect safe operation of
the generator.
• When working on this equipment, remain alert
at all times. Never work on the equipment when
physically or mentally fatigued.
• Before performing any maintenance on the generator, disconnect its battery cables to prevent
accidental start up. Disconnect the cable from the
battery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.
• Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating conditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.
• Never insert any tool or other object through openings in the generator interior, even if the unit is not
running. Serious injury or damage to the equipment may occur.

Safety Rules
Recreational Vehicle Generator

 Electrical Hazards 

 Fire Hazards 

• The generator covered by this manual produces
dangerous electrical voltages and can cause fatal
electrical shock. Avoid contact with bare wires, terminals, connections, etc., while the unit is running.
Ensure all appropriate covers, guards and barriers
are in place before operating the generator. If work
must be done around an operating unit, stand on
an insulated, dry surface to reduce shock hazard.
• Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands or
feet are wet. DANGEROUS ELECTRICAL SHOCK
MAY RESULT.
• During installation onto the vehicle, properly
ground (bond) the generator either by solid mounting to the vehicle frame or chassis, or by means of
an approved bonding conductor. DO NOT connect
the bonding conductor to any generator part that
might be removed or disassembled during routine
maintenance. If the grounding conductor must be
replaced, use only a flexible conductor that is of
No. 8 American Wire Gauge (AWG) copper wire
minimum.
• If the vehicle electrical circuits can be powered by
any other source of electricity (such as a “dockside”
power receptacle), there must be no possibility of
connecting the different power sources to the vehicle circuits at the same time. The dockside (utility)
power source must be positively isolated from the
vehicle circuits whenever the generator is operating. Failure to isolate the vehicle circuits from
the dockside power supply when the generator is
running may result in damage to the generator or
serious injury or death to dockside (utility) power
workers due to backfeed of electrical energy.
• In case of accident caused by electric shock, immediately shut down the source of electrical power.
If this is not possible, attempt to free the victim
from the live conductor. AVOID DIRECT CONTACT
WITH THE VICTIM. Use a nonconducting implement, such as a rope or board, to free the victim
from the live conductor. If the victim is unconscious, apply first aid and get immediate medical
help.
• Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving components causing injury.

• For fire safety, the generator must be installed
and maintained properly. Installation always must
comply with applicable codes, standards, laws
and regulations. Adhere strictly to local, state and
national electrical and building codes. Comply
with regulations the Occupational Safety and
Health Administration (OSHA) has established.
Also, ensure that the generator is installed in
accordance with the manufacturer’s instructions
and recommendations. Following proper installation, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regulations.
• Keep a fire extinguisher in the vehicle at all times.
Extinguishers rated “ABC” by the National Fire
Protection Association are appropriate for use on
the recreational vehicle generator electrical system.
Keep the extinguisher properly charged and be
familiar with its use. If there are any question pertaining to fire extinguishers, consult the local fire
department.

 Explosion Hazards 
• Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no combustible materials are left in the generator compartment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surrounding the generator clean and free from debris.
• Gasoline is extremely FLAMMABLE and its vapors
are EXPLOSIVE. Do not permit smoking, open

Section 2 – Installation
Recreational Vehicle Generator

2.1 Location and Support
 2.1.1 GENERATOR LOCATION
The most desirable location for the generator set is
between the vehicle's main frame members. However,
this is seldom possible. Most units must be installed
on the side of the vehicle and are difficult to reinforce.
Many recreational vehicles have been factory equipped
with an area for the generator set. Some vehicles may
even have a generator compartment provided by the
vehicle manufacturer.
Plan the generator location based on the following:
• The generator set must be installed on a framework that is part of the recreational vehicle, as
outlined in Section 2.1.2.
• The location must provide an access opening
that is large enough to permit generator removal
(unless the generator is to be removed from underneath the supporting framework).
• The location must provide easy access to frequently serviced components, such as filters, oil drains,
spark plugs and other common maintenance
parts.
• The location must provide sufficient room to allow
minimum clearances as outlined in Section 2.2. If
sound insulation is to be used on the compartment
walls and ceiling, the minimum recommended
applies to the space between the generator and
such insulation.
• The location must provide adequate cooling and
ventilating airflow for the generator without a great
deal of work and expense.
• If mounting the generator in an enclosed compartment, the base of the generator must rest flat on
the floor without any gaps.
• When using a suspended mounting system, ensure
the base of the generator is flush with the surrounding bodywork. If the unit is mounted higher
in the structure, heated air may recirculate into the
generator causing it to overheat.

 2.1.2 GENERATOR SUPPORT
The generator must be securely attached to a metal
framework that has been made part of the vehicle
frame structure by bolting or welding. The metal
framework on which the generator will rest and
which will restrain the generator set should consist
of at least two horizontal beams. These beams should
consist of (a) 1-1/2-inch square, 11-gauge steel tubing OR (b) 1-1/2-inch, 11-gauge angle iron. A typical
supporting frame with horizontal support tubing, is
shown in Figure 2.1.
The generator can be installed so that it sits on top
of the horizontal support tubing if the vehicle design
permits. Another method is to suspend the genera 20

tor below the horizontal support tubing by means of
suitable, structurally sound metal framework. The
following general rules apply:
• Vehicle construction MUST be capable of supporting the weight of the generator.
• Whether the generator is mounted above the horizontal support tubing or suspended below the tubing, the supporting frame used must be structurally sound.
• If the generator cannot be bolted directly to
the supporting frame or support tubing, consider using additional tubing, angle brackets
or other supports to give the supporting frame sufficient strength.

Figure 2.1 – Typical Horizontal Support Frame

 2.1.4 GENERATOR RESTRAINT
Use four 5/16"-18 hardened steel bolts (Grade 5) to
fasten the generator to the supporting frame or the
support tubing. These bolts must pass through (a)
the generator mounting base, (b) the compartment
floor (if a compartment is used) and (c) the supporting framework (Figure 2.2). All bolts must be long
enough so that when tight, at least three threads are
visible past the retaining lock nuts. Refer to Section
2.2 for the location of the generator mounting holes.

Figure 2.2 – Typical Generator Restraint

Section 2 – Installation
Recreational Vehicle Generator

2.2 Generator Compartments

Figure 2.4 – Typical Compartment Construction

Whether the generator set is being installed inside a
compartment specifically manufactured to house a
generator or inside a compartment that the installer
constructs, the compartment must meet certain specifications as outlined in the following sections:

 2.2.1 COMPARTMENT SIZE
Plan the compartment size carefully. Provide a minimum clearance of 1/2 inch (13 mm) on the front and
top, 1/2 inch (25 mm) on the left side, two (2) inches
on the right side, and 2-1/2 inch (63.5 mm) from the
back for air circulation AFTER the compartment has
been lined with metal and sound insulation (Figure
2.3).

Refer to “Figure 1.2 – Major Features and
Dimensions”.

 2.2.2 COMPARTMENT Construction
• The generator compartment should be either constructed of, or lined with, 26-gauge galvanized
steel.
NOTE:
Aluminum is NOT an acceptable alternative
to galvanized steel due to aluminum’s low
melting point.
• If the compartment is lined with galvanized steel,
it may be constructed of any material. The manufacturer recommends that the compartment be
constructed of 1/2-inch thick plywood (not strandboard), with the floor made of a double thickness
of 1/2-inch plywood with the grain of the wood at
cross section for added strength (Figure 2.4).
• If constructing a compartment, line the exterior
(underside) of the compartment floor with 26gauge galvanized steel.

• All seams, splices and joints of the compartment walls (unless vapor tight by design) should
be caulked to prevent poisonous, flammable or
explosive vapors from entering the vehicle interior.
NOTE:
Caulking must be done so that the caulking material will stay in place permanently. Pressing such
materials as putty tape onto joints and seams is
not acceptable. A high quality silicone rubber base
sealant is recommended.
• Holes and openings made in the compartment
walls to allow for the passage of electrical conduit,
conductors, hoses, cables, etc., into the vehicle living area must be sealed vapor tight with silicone
rubber base sealant.
• If flexible metal conduit is used, it must be sealed
internally at the end where it terminates inside the
compartment’s electrical junction box.
NOTE:
Flexible metal conduit, due to its unique construction, is NOT vapor tight along its entire length.
• Seams and joints of the galvanized steel (whether
used as a liner or for the compartment itself) must
be lapped and mechanically secured. Such seams
may be manufactured, welded, bolted, riveted or
screwed. Manufactured lock seams are shown in
Figure 2.5. Installer constructed compartments
typically utilize a standard lap joint.
• After the compartment has been metal lined and
vapor sealed, line the compartment interior walls
and ceiling with an approved, nonflammable sound
insulating material. See Section 2.2.3.

Section 2 – Installation
Recreational Vehicle Generator

Figure 2.5 – Types of Lock Seams

 2.2.4 ACOUSTICS
For additional noise abatement, the installer may
wish to consider the following:
• Using special sound insulating materials.
• Construction of a special noise abatement
compartment.
NOTE:
Any method used to reduce noise must not
adversely affect the flow of cooling and ventilating
air into or out of the compartment.

danger



o not install any flammable material directly
D
above or around the compartment. Heat,
transferred through the compartment structure,
may be sufficient to ignite, char or discolor
seat cushions, fiberboard and other flammable
materials. Use approved nonflammable insulating materials in high temperature areas.

 2.2.3 Sound Insulating Materials
Once installers have determined that a compartment
is properly constructed and metal lined, they can add
acoustical material. This may include additional sealant or insulating material, to reflect noise away from
the vehicle interior.
Sound insulating materials should be of a nonflammable type. One excellent insulating material is a 1inch (25 mm) thick fiberglass having a 2-pound density. When fiberglass is used, its coated side should
face toward the compartment interior.

danger
Do not install sound insulation or any absorbent
 material
on the compartment floor interior. Such
materials will become soaked with combustible
or explosive vapors and liquids and will become
a fire hazard.
Using a combination of sound insulating materials
can often reduce noise more effectively than a single
material. For example, a sheet of lead or visco-elastic
material, along with a layer of other acoustical material, is more effective than when a single material is
used.

In addition to the effective use of sound insulating
materials, construction of a special noise abatement
compartment might be considered to reduce noise
levels. Such a compartment might be constructed as
follows (Figure 2.6):
• Use 5/8-inch thick or 3/4-inch thick plywood in the
compartment.
• Construct the compartment floor of a double thickness of 5/8-inch or 3/4-inch plywood.
• Line the compartment interior walls and floor, as
well as the underside of the floor, with 26-gauge
galvanized steel.
• Vapor seal all compartment seams and joints.
• Over the galvanized steel lining, install a combination of acoustical materials as mentioned in
Section 2.2.3.

danger
To prevent fire or explosion, do not install any
 insulation
or other absorbent materials on the

interior or underside of the compartment floor.
• Seal all compartment door edges to prevent noise
leakage around the door perimeter.
• Line the compartment door interior (except for air
openings) with suitable, fireproof sound insulation
(such as 1-inch (25 mm) thick fiberglass with a 2pound density).

2.3 Cooling and Ventilating Air

It is absolutely essential that an adequate flow of
air for cooling, ventilating and engine combustion
be supplied to the generator set. Without sufficient
airflow, the engine/generator quickly overheats. Such
overheating can cause serious operating difficulties
and also may cause fire and personal injury. The
installer must make sure that sufficient air is available to the generator for cooling, ventilating and
combustion. The installer also must provide for a
path for exhausting the cooling air to the exterior of a
compartment, if so equipped.

danger

AC OUTPUT
HARNESS

Never use discharged cooling air for heating or
 permit
such air to enter the vehicle interior. This
air contains deadly carbon monoxide gas and
other poisonous, flammable or explosive gases.

 2.3.1 GENERATOR airflow
Engine operation drives cooling fans for the two-stage
cooling air system. A pressure fan draws cooling air
into the bottom right side of the generator (Figure
2.8). This airflow cools the engine/generator and electronic components. The second part of the cooling
system, a suction fan, draws air that is heated from
a hot engine into a collector compartment at the left
side of the unit. This heated air (although cooler than
exhaust muffler) is then deflected out the bottom
toward the ground.

Section 2 – Installation
Recreational Vehicle Generator

Figure 2.8 – Airflow Through Engine/Generator

danger
Use only approved components in the fuel sup ply
system. All components must be properly

installed in accordance with applicable codes.
Improper installation or use of unauthorized
components may result in fire or an explosion.
Follow approved methods to test the system
for leaks. No leakage is permitted. Do not allow
fuel vapors to enter the vehicle interior.

Figure 2.9 – Typical Propane Gas Fuel System

 2.3.2 TESTING THE INSTALLATION
The manufacturer recommends testing the installation to be sure adequate cooling airflow is available to
the unit before placing the unit into service. If the unit
shows signs of overheating, enlarge the air openings.
Never place a unit into service until absolutely certain
that cooling and ventilation is adequate.
NOTE:
Test the installation, especially if bringing in air
from below the generator set.

2.4 LP Gas Fuel System
danger
LP gas is highly explosive. The gas is heavier
 than
air and tends to settle in low areas. Even

the slightest spark can ignite it and cause and
explosion. Only competent, qualified people
should be allowed to install, test, adjust or service an LP gas fuel system. Install the optional
fuel system in compliance with applicable codes,
standards and regulations. After the installation, do not do anything that might render the
system in noncompliance with applicable codes
and standards.
The LP powered range of generators are fitted with a
nonadjustable, factory set system. These systems are
tamper-proof to meet 1997 California Air Resources
Board requirements for engine emission.

 2.4.1 Parts not Included in Fuel
System
The propane fuel system does NOT include such
items as (a) gas tank, (b) gas piping, (c) fittings, (d)
valves, and (e) primary regulator, used to store the
gaseous fuel and deliver it to the gaseous fuel solenoid (Figure 2.9).
24

 2.4.2 SOME IMPORTANT CONSIDERATIONS
When installing an LP gas system, consider seriously
the following items:
• All fittings, lines, hoses and clamps must be
tight and free of leaks. Apply a pipe sealant to
threads when assembling threaded connections.
This reduces the possibility of leakage.
• Test the entire fuel system for leaks using approved
test methods.
• Optimum gas pressure at the inlet to the gaseous
fuel solenoid valve and secondary regulator is 11
inches water column.
• The installer’s fuel supply connection point is at
the gaseous fuel solenoid valve. This is a 3/4-inch
(female) connection. Provide a suitable 3/4-inch
NPT (male) connector to attach to the fuel supply
line.

Section 2 – Installation
Recreational Vehicle Generator

• Use a length of approved flexible fuel hose between
the gaseous fuel solenoid valve and rigid gas piping. The flexible line should be at least 6 inches
longer than necessary.

Figure 2.10 – LP Gas Carburetion Diagram

 2.4.3 vapor withdrawal
LP gas is stored in pressure tanks as a liquid. The
gas systems used with these generators were designed
only for vapor withdrawal type systems. Vapor withdrawal systems use the gas vapors that form above
the liquid fuel in the tank. Do NOT attempt to use the
generator with any liquid withdrawal type system.

 2.4.4 primary regulator
Gas pressure delivered to the solenoid valve must be
properly regulated by means of a primary gas regulator. Mount the primary regulator at the gas tank
outlet or in the supply line from the gas tank. The
following rules apply:
• For best results, the primary regulator supplies
gaseous fuel to the secondary regulator at 11 inches water column. Do NOT exceed 14 inches water
column.
• The installer must be sure the primary regulator is
rated at sufficient gas flow to operate the generator
plus all other gas appliances in the circuit.
NOTE:
Recommended MINIMUM gas flow rate for all aircooled generators is 40 cubic feet per hour.
If an existing primary gas regulator does not have
a sufficient flow capacity for the generator and
other gas appliances in the circuit, (a) install a
primary regulator with adequate flow rate, or (b)
install a separate regulator only and rated at least
40 cubic feet per hour. The inlet side of any primary regulator that supplies the generator must
connect directly to a gas pressure tank. Do NOT
tee the generator line into a gas circuit feeding
other areas.

 2.4.5 GASEOUS CARBURETION
LP gas vapors should be supplied to the secondary
regulator inlet at about 11 inches water column (positive pressure). The engine pistons draw air in during the intake stroke (Figure 2.10). This air passes
through a carburetor venturi, which creates a low
pressure that is proportional to the quantity of air
being pumped. The low pressure from the carburetor
venturi acts on the regulator diaphragm to pull the
diaphragm toward the source of low pressure. A lever
attached to the diaphragm opens a valve to permit
gas glow through the carburetor.

The greater the airflow through the carburetor venturi, the lower the pressure at the venturi throat. The
lower the pressure at the venturi throat, the greater
the diaphragm movement, and the greater the movement of the regulator valve. The more the regulator
valve opens, the greater the gas flow that is proportional to airflow through the generator.
The following facts about the secondary regulator
must be emphasized:
• The regulator must be sensitive to venturi throat
pressure changes throughout the operating range.
• The regulator must be properly adjusted so it will
stop the flow of gas when the engine is not running
(no air flow through the carburetor).
• The slightest airflow (and vacuum in the venturi
throat) should move the regulator valve off its seat
and permit gas to flow.

 2.4.6 fuel supply lines
• LP gas lines must be accessible, but protected
against possible damage.
• Do NOT connect electrical wiring to any LP gas fuel
line or run wiring alongside the lines.
• Route gas lines away from hot engine exhausts.
• Retain gas lines with metal clamps that do not have
sharp edges.
• Install an approved length of flexible hose between
the gaseous fuel solenoid valve and rigid fuel
supply lines. The flexible line must be nonmetallic, nonorganic and nonconductive. It must be
approved for use with LP gas.

 2.4.7 excess flow valve
LP gas tanks should have an excess flow valve,
according to NFPA 501C, Paragraph 3-4.4. This
valve and the gas lines must be carefully sized so the
valve will close when a fuel line is severed or broken.
Consult the Natural-LP Gas Association for information and limitations of excess flow valves.
Manual shutoff valves on the supply tank and elsewhere in the system must be fully open when operating the generator. The excess flow valve functions
properly only if all valves are fully open.

Section 2 – Installation
Recreational Vehicle Generator

 2.4.8 leakage tests
Do not place the generator into service until the gas
system has been properly tested for leaks. To test the
system, a separate source of 12 volts DC is needed to
open the gaseous fuel solenoid valve.
The leak test must comply fully with NFPA, Paragraph
318. All connections, hoses, valve regulators, fittings,
and other fuel system parts must be tested under
gas or air pressure of not less than 90 psi (620 kPa),
while using soap and water or an equivalent solution
to check for leaks. Other approved methods of testing
for leaks may be used, if appropriate. DO NOT USE
ANY FLAME TO TEST FOR LEAKS.

danger
Gaseous fuel lines between the tank and the
 secondary
regulator are under a positive pres-

sure (about 11 inches water column). Gas pressure at the outlet side of the secondary regulator, however, is a negative pressure and can
draw flame inside a line or fitting and cause an
explosion.

2.5 Exhaust 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 concentrations, 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.

 2.5.1 SPARK ARRESTOR
This spark arrestor assembly 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.
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 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 arrestor components, verify that the tailpipe has a hole
to securely fasten the spark arrestor components
(see Figures 2.11 and 2.12). Use only manufacturer

2.6 Electrical Connections
Be sure to read Section 1.6.

The following general rules apply to electrical connections in a recreational vehicle:

40 [1.58"]

5.5 [7/32"] DRILL
BOTTOM SIDE ONLY

 2.5.2 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 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 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
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 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 regulations.

• Qualified electricians who are familiar with applicable 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 compartment (if used) must be vapor-sealed to prevent
entry of flammable, explosive or poisonous gases
into the vehicle.

 2.6.1 ELECTRICAL JUNCTION BOX
Install an approved, square electrical junction box
with a blank cover on the interior or exterior wall of
the area planed 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.

 2.6.2 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.
• Neutral conductors must be the same size as other
leg wires.
• Route power supply conductors from generator AC
output leads (white), (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 generator and the compartment junction box, the conduit end that terminates the compartment junction
box must be vapor-sealed. Flexible metal conduit
is NOT vapor tight along its entire length.
• From the junction box, route power supply wires
through approved conduit to either (a) double-pole,
double-throw transfer switch, or (b) approved isolation receptacle. Connecting to a transfer switch
or isolation receptacle must prevent vehicle electrical circuits from being connected to two different
power supplies at the same time (such as generator and dockside power).

 2.6.3 GENERATOR AC CONNECTIONS
Generator AC output leads (BLACK) “hot” and
(WHITE) grounded neutral come out of the generator
as shown in Figure 2.13. There is also a green lead
that connects to ground in the junction box of the
recreational vehicle.

HARNESS

• If using metallic conduit, vapor seal the end of the
conduit where it enters the junction box. Do this
because flexible metallic conduit is not vaporproof
along its entire length.

 2.6.5 ISOLATING DIFFERENT POWER
SOURCES
Connections from the junction box must terminate in
a double-pole, double-throw transfer switch (Figure
2.14). An alternate method for isolating different
power sources is by using an isolating receptacle
(Figure 2.15). Whichever method is used, be certain
that both power sources are NOT connected at the
same time.

 2.6.6 POWER SUPPLY CORD
The power supply cord must comply with all applicable codes, standards and regulations. It must be
large enough to handle the full amperage to which it
will be subjected.

 2.6.7 GROUND FAULT CIRCUIT
INTERRUPTERS

Leads BLACK to WHITE are protected against overload by a 30-amp circuit breaker (CB1). Use this
line-to-neutral connection separately to operate 120volt, single-phase, 60 Hertz, AC loads requiring up to
3,400 watts (3.4 kW) of power.



o NOT connect electrical loads in excess of any
D
circuit breaker rating or probems will develop
with circuit breaker tripping, which causes a loss
of AC output. Also, do NOT exceed the generator's rated wattage capacity. Add the watts
or amperes of all lighting, appliance, tool and
motor loads the generator will operate at one
time. This total should be less than the unit's
rated wattage/amperage capacity.

 2.6.4 CONDUIT
Route the connections between the generator and the
junction box through approved, flexible conduit. The
following general rules apply:
• Cut wiring to the required length and allow extra
wire for junction box connections.
• Carefully prepare conduit ends to prevent sharp
edges from cutting through wiring insulation.
• Route conduit so it does not interfere with generator movement.
28

The National Electrical Code (NFPA 70, 551-7)
requires that ground fault circuit interrupters (GFCIs)
be installed on all external and some internal electrical receptacles. Contact the dealer for recommendations.

2.7 Battery Installation
 2.7.1 RECOMMENDED BATTERY
Install a battery
requirements:

that

meets

the

following

• The battery must be a 12-volt, automotive type
storage battery.
• For prevailing ambient temperatures above 32°
F (0° C), use a battery rated 70 amp-hours and
capable of delivering 400 cold-cranking amperes.
• For prevailing ambient temperatures below 32°
F (0° C), use a battery rated 95 amp-hours and
capable of delivering 400 cold-cranking amperes.
NOTE:
If the battery is to be used to power other vehicle
accessories, as well as start the generator, a battery with a larger capacity may be needed.

 2.7.2 BATTERY CABLES
Using battery cables that are too long or too small in
diameter may cause a drop in voltage, which causes
starting problems. For the best cold weather starting,
the voltage drop between battery terminals and the
generator connection point should not exceed 0.12
volts per 100 amperes of cranking current.

Section 3 – Post-installation Start-up Adjustments
Recreational Vehicle Generator

3.1 Post Installation Tests

The air-cooled generator set was factory tested and
adjusted. It should not be necessary to adjust the unit
any further except under special circumstances.

Do not make any unnecessary adjustments.
 Factory
settings are correct for most applica-

tions. When making adjustments, however, be
careful to avoid overspeeding the engine.

3.2 BEFORE INITIAL START-UP
Before starting, complete the following:

1. Check the engine crankcase oil level and, if necessary, fill to the dipstick “FULL” mark (crosshatched area) with the recommended oil. Do not
fill above the FULL mark.
2. Check the fuel supply. Gas fuel lines must have
been properly purged and leak tested in accordance with applicable fuel codes. All fuel shutoff
valves in the fuel supply lines must be open.

danger
If a liquid propane (LP) gas fuel system has been
 installed,
it must be properly tested for leaks
before operating the system in compliance with
ANSI A119.2/NFPA 501C. No leakage is permitted. Be sure no gasoline fuel vapors enter the
vehicle interior.

3.3 INITIAL START

When absolutely certain that the unit has been properly installed and prepared for use, start the engine
as follows:
1. Turn off all electrical loads. Do this by setting the
generator’s main circuit breakers to their “OFF”
(or open) position.
2. Refer to Part I, Section 2.5, “Starting the
Generator”, for cranking and starting instructions. The engine may require more cranking
for initial starting since the fuel lines have to be
primed (use of the primer switch will shorten this
time).

3. Let the engine warm up for about five minutes to
allow internal temperatures to stabilize.
4. Carefully inspect the engine/generator for fuel, oil
and exhaust system leaks. Before proceeding to
the next step, correct any leakage immediately.
5. When all tests and adjustments at no-load are
completed, apply electrical loads and check for
proper operation under load. See Section 3.4.
Run the unit at least 30 minutes with loads
applied.
6. Turn off all electrical loads by setting the generator’s main circuit breakers to their “OFF” (or
open) position.
7. Let the unit run at no-load for a few minutes to
stabilize internal engine/generator temperatures.
Then, shut down the engine.
NOTE:
The generator set was thoroughly tested and
adjusted at the factory before shipping. No additional adjustment should be necessary. Only qualified service technicians who have been trained
should perform adjustments outlined in this
manual.

3.4 TESTING UNDER LOAD

Apply electrical loads equal to about 75 to 100 percent of the unit's rated wattage/amperage capacity.
Let the unit run at least 30 minutes with load applied.
During this part of the test, check that the unit is not
running excessively hot and that adequate cooling
airflow is available. Do not allow the unit to overheat
during prolonged operation.
NOTE:
The generator engine is equipped with a high temperature switch. The switch has normally closed
(N.C.) contacts. When the engine temperature is
too high, switch contacts close, and the engine
shuts down automatically.
THE MANUFACTURER recommends testING
the generator for adequate cooling.

CALIFORNIA AND FEDERAL EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board (CARB) and the United States Environmental Protection Agency (EPA), together with
Generac Power Systems, Inc. (Generac), are pleased to explain the Emission Control System Warranty on your new engine.*
New utility, and lawn and garden equipment engines must be designed, built and equipped to meet stringent anti-smog
standards for the state of California and the federal government. Generac will warrant the emission control system on your
engine for the periods of time listed below provided there has been no abuse, neglect, unapproved modification or improper
maintenance of your engine.
Your emission control system may include parts such as the carburetor, ignition and exhaust systems. Generac will repair
your engine at no cost to you for diagnosis, replacement parts and labor, should a warrantable condition occur.

MANUFACTURER’S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:
Emissions control systems on 1997 and later model year engines are warranted for two years as hereinafter noted. If, during such warranty period, any emission-related component or system on your engine is found to be defective in materials or
workmanship, repairs or replacement will be performed by a Generac Authorized Warranty Service Facility.

PURCHASER’S/OWNER’S WARRANTY RESPONSIBILITIES:
As the engine purchaser/owner, you are responsible for the completion of all required maintenance as listed in your factory
supplied Owner’s Manual. For warranty purposes, Generac recommends that you retain all receipts covering maintenance
on your engine. However, Generac cannot deny warranty solely because of the lack of receipts or for your failure to ensure
the completion of all scheduled maintenance.
As the engine purchaser/owner, you should, however, be aware that Generac may deny any and/or all warranty coverage or
responsibility if your engine, or a part/component thereof, has failed due to abuse, neglect, improper maintenance or unapproved modifications, or the use of counterfeit and/or ‘grey market’ parts not made, supplied or approved by Generac.
You are responsible for presenting your engine to a Generac Authorized Warranty Service Facility as soon as a problem
occurs. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.
Warranty service can be arranged by contacting either your selling dealer or a Generac Authorized Warranty Service Facility.
To locate the Generac Authorized Warranty Service Facility nearest you, call our toll-free number:

1-800-333-1322
IMPORTANT NOTE: This warranty statement explains your rights and obligations under the Emission Control System
Warranty (ECS Warranty), which is provided to you by Generac pursuant to California and federal law. See also the “Generac
Limited Warranties for Generac Power Systems, Inc.,” which is enclosed herewith on a separate sheet, also provided to you
by Generac. The ECS Warranty applies only to the emission control system of your new engine. If there is any conflict in
terms between the ECS Warranty and the Generac Warranty, the ECS Warranty shall apply except in circumstances where
the Generac Warranty may provide a longer warranty period. Both the ECS Warranty and the Generac Warranty describe

EMISSION CONTROL SYSTEM WARRANTY
Emission Control System Warranty (ECS Warranty) for 1997 and later model year engines:
(a) Applicability: This warranty shall apply to 1997 and later model year engines. The ECS Warranty Period shall begin on
the date the new engine or equipment is purchased by/delivered to its original, end-use purchaser/owner and shall continue
for 24 consecutive months thereafter.
(b) General Emissions Warranty Coverage: Generac warrants to the original, end-use purchaser/owner of the new engine or
equipment, and to each subsequent purchaser/owner, that each of its engines is ...
(1) Designed, built and equipped so as to conform with all applicable regulations adopted by the EPA and CARB pursuant
to their respective authority, and
(2) Free from defects in materials and workmanship which, at any time during the ECS Warranty Period, may cause a
warranted emissions-related part to fail to be identical in all material respects to the part as described in the engine
manufacturer’s application for certification.
(c) The ECS Warranty only pertains to emissions-related parts on your engine, as follows:
(1) Any warranted, emissions-related parts that are not scheduled for replacement as required maintenance in the Owner’s
Manual shall be warranted for the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall
be repaired or replaced by Generac according to Subsection (4) below. Any such part repaired or replaced under the ECS
Warranty shall be warranted for the remainder of the ECS Warranty Period.
(2) Any warranted, emissions-related part that is scheduled only for regular inspection as specified in the Owner’s Manual
shall be warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair or replace
as necessary” shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty
shall be warranted for the remainder of the ECS Warranty Period.
(3) Any warranted, emissions-related part that is scheduled for replacement as required maintenance in the Owner’s
Manual shall be warranted for the period of time prior to the first scheduled replacement point for that part. If the part
fails prior to the first scheduled replacement, the part shall be repaired or replaced by Generac according to Subsection
(4) below. Any such emissions-related part repaired or replaced under the ECS Warranty shall be warranted for the
remainder of the ECS Warranty Period prior to the first scheduled replacement point for such emissions-related part.
(4) Repair or replacement of any warranted, emissions-related part under this ECS Warranty shall be performed at no
charge to the owner at a Generac Authorized Warranty Service Facility.
(5) When the engine is inspected by a Generac Authorized Warranty Service Facility, the owner shall not be held responsible
for diagnostic costs if the repair is deemed warrantable.
(6) Generac shall be liable for damages to other original engine components or approved modifications proximately caused
by a failure under warranty of any emission-related part covered by the ECS Warranty.
(7) Throughout the ECS Warranty Period, Generac shall maintain a supply of warranted emission-related parts sufficient
to meet the expected demand for such emission-related parts.
(8) Any Generac authorized and approved emission-related replacement part may be used in the performance of any ECS
Warranty maintenance or repairs and will be provided without charge to the purchaser/owner. Such use shall not reduce
Generac’s ECS Warranty obligations.
(9) Unapproved, add-on, modified, counterfeit and/or ‘grey market’ parts may not be used to modify or repair a Generac
engine. Such use voids this ECS Warranty and shall be sufficient grounds for disallowing an ECS Warranty claim.
Generac shall not be held liable hereunder for failures of any warranted parts of a Generac engine caused by the use of
such an unapproved, add-on, modified, counterfeit and/or ‘grey market’ part.

Generac RV generators manufactured prior to December 31, 1997, DO NOT have a transferable warranty. Generac RV generators
manufactured after January 1, 1998, have a transferable warranty to the second owner only for the remainder of the three-year
limited warranty. Proof-of-purchase is required and must be presented to a Generac Authorized Warranty Service Facility prior to the

All warranty expense allowances are subject to the conditions defined in Guardian’s Warranty Policies and Procedures Guide.
THIS WARRANTY SHALL NOT APPLY TO THE FOLLOWING:
• Generac Guardian generators that utilize non-Generac replacement parts.
• Costs of normal maintenance, adjustments, installation and start-up.
• Repairs or diagnostics performed by individuals other than Guardian/Generac authorized dealers not authorized in writing by
Generac Power Systems.
• Failures caused by any contaminated fuels, oils, coolants or lack of proper fluid amounts.
• Failures due, but not limited, to normal wear and tear, accident, misuse, abuse, negligence or improper installation. As with all
mechanical devices, the Generac engines need periodic part(s) service and replacement to perform well. This warranty will not
cover repair when normal use has exhausted the life of a part(s) or engine.
• Failures caused by any external cause or act of God, such as collision, theft, vandalism, riot or wars, nuclear holocaust, fire,
freezing, lightning, earthquake, windstorm, hail, volcanic eruption, water or flood, tornado or hurricane.
• Damage related to rodent and/or insect infestation.

THIS WARRANTY IS IN PLACE OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED. SPECIFICALLY, GENERAC MAKES NO
OTHER WARRANTIES AS TO THE MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Some states do not allow
limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
GENERAC'S ONLY LIABILITY SHALL BE THE REPAIR OR REPLACEMENT OF PART(S) AS STATED ABOVE. IN NO EVENT SHALL
GENERAC BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN IF SUCH DAMAGES ARE A DIRECT
RESULT OF GENERAC'S NEGLIGENCE. Some states do not allow the exclusion or limitation of incidental or consequential damages,
so the above limitation may not apply to you.
This warranty gives you specific legal rights. You also have other rights from state to state.
