Installation
We sincerely appreciate your patronage. For this reason, we
have made every effort to provide for a safe, streamlined
and cost-effective installation. Because each installation is
unique, it is impossible to know of and advise the trade of all
conceivable procedures and methods by which installation
might be achieved. Neither could we know of possible
hazards and/or the results of each method or procedure.
For these reasons, only current licensed electrical and
plumbing professionals should attempt generator system
installations. Installations must strictly comply with all
applicable codes, industry standards andregulations.
Your generator is supplied with this “Operator’s Manual”
and a separate “Installation Manual”. These are important
documents and should be retained by the owner after the
installation has been completed.
This product is only for use as an optional generator system
which provides an alternate source of electric power and
to serve loads such as heating, refrigeration systems, and
communication systems that, when stopped during any power
outage, could cause discomfort or inconvenience.
NOTICE This product does NOT qualify for either an
emergency standby or legally required standby system as
defined by NFPA 70 (NEC).
• Emergency generator systems are intended to
automatically supply illumination, power, or both, to
designated areas and equipment in the event of failure
of the normal supply. Emergency systems may also
provide power for such functions as ventilation where
essential to maintain life, where current interruption of
the normal supply would produce serious life safety or
health hazards.
• Legally Required standby generator systems are
intended to automatically supply power to selected
loads in the event of failure of the normal source
which could create hazards or hamper rescue or fire-
fighting operations.
Every effort has been made to ensure that information in this
manual is accurate and current. However, we reserve the right
to change, alter, or otherwise improve the product and this
document at any time without prior notice.
Only current licensed electrical and plumbing professionals
should attempt generator system installations. Installations
must strictly comply with all applicable codes, industry
standards, laws and regulations.
For the Installing Dealer/Contractor:

the information required to properly install and start the
generator. This operator’s manual describes routine operation
and owner maintenanceprocedures.
If you need more information in this matter, please call
800732-2989, between 8:00 AM and 5:00 PM CT.
Owner Orientation
This section provides generator owners with the information
necessary to achieve the most satisfactory and cost effective
installation possible.
The illustrations are for typical circumstances and are meant
to familiarize you with the installation options available
with your generator. A thorough understanding of these
options will provide fundamental control over the cost of
your installation, as well as ensure your final satisfaction
andsecurity.
Federal and local codes, appearance, noise levels, fuel types,
and distances are the factors that must be considered when
negotiating with an installation professional. Remember
that as the distance from the existing electrical service and
gaseous fuel supply increases, and the number of 90 degree
bends in the fuel supply increases, compensations in piping
and wiring materials must be made. This is necessary to
comply with local codes and overcome electrical voltage
drops and gaseous fuel pressure drops.
The factors mentioned above will have a direct affect on
the overall price of your generator installation.
In some areas you may need to acquire electrical permits
for installing the generator, building permits for installing
gas lines, and permits for noise allowances. Your installer
should check your local codes AND obtain the permits before
installing the system.
For the Owner:
To help you make informed choices and communicate
effectively with your installation contractor(s), read and
understand Owner Orientation in this manual before
contracting or starting your generatorinstallation.
To arrange for proper installation, contact the store at which
you purchased your generator, your dealer, a licensed
electrician or your utility power provider.
The generator warranty is VOID unless the system is
installed by licensed electrical and plumbingprofessionals.
Every effort has been made to ensure that information in this
manual is accurate and current. However, we reserve the
right to change, alter, or otherwise improve the product and
this document at any time without prior notice.

Fuel Factors
An important consideration affecting the entire installation
is the type of fuel used by your generator. The system was
factory tested and adjusted using either natural gas or liquid
propane (LP vapor). For proper engine function, factors
that are inherent to each of these fuels, your location and
the duration of possible utility interruptions are important
considerations in the following fuel guidelines:
• Use clean, dry fuel, free of moisture or any
particulate material. Using fuels outside the following
recommended values may cause performanceproblems.
• In engines set up to run on propane (LP), commercial
grade HD5 propane with a minimum fuel energy of 2500
BTUs/ft3 with maximum propylene content of 5% and
butane and heavier gas content of 2.5% and minimum
propane content of 90%.
Natural gas rating will depend on specific fuel but typical
derates are between 10 to 20% off the LP gas rating.
Power Decrease at High Altitude or High Temperature
Air density is less at high altitudes, resulting in less available
engine power. Specifically, engine power will decrease 3%
for each 1,000 feet (300 meters) above sea level and 1% for
each 10° F (5.6°C) above 77°F (25°C). Make sure you and
your installer consider these factors when determining total
generator load.
Delivery Inspection
Carefully inspect the generator for any damage that may have
occurred during shipment.
If loss or damage is noted at time of delivery, have the
person(s) making delivery note all damage on the freight bill
and affix his signature under the consignor’s memo of loss
or damage. If loss or damage is noted after delivery, separate
the damaged materials and contact the carrier and your
installer for claim procedures. Missing or damaged parts are
not warranted.

Operation
Important Owner’s Considerations
Engine Oil
This engine is shipped from the factory pre-run and filled
with non-synthetic oil (API SL 10W-30W). This allows
for system operation in a wide range of temperature and
climate conditions. Before starting the engine, check oil
level and ensure that engine is serviced as described in the
Maintenance section.
Coolant System
This engine is shipped from the factory filled with a
50-50 mix of automotive (ethylene glycol) anti-freeze and
water. This will provide optimum year round protection
against freezing, boiling and corrosion.
Battery
The installer must supply a valve-regulated, rechargeable
12 volt DC starting battery. See Battery in Final Installation
Considerations in the installation manual.
15 Amp Fuse
The generator’s 15 Amp fuse is critical to correct system
operation. The 15 Amp fuse was removed at the factory to
prevent the unit from starting during shipping. Your installer
will ensure the fuse is properly installed upon completion of
the installation.
NOTICE Any attempt to crank or start the engine before it
has been properly serviced with the recommended coolant
or oil will result in equipment failure.
• Refer to the Maintenance section for coolant and oil fill
information.
• Damage to equipment resulting from failure to follow this
instruction will void engine and generator warranty.
WARNING Battery posts, terminals and related
accessories contain lead and lead compounds - chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.
Automatic Operation
The generator’s control board constantly monitors utility
voltage. Should utility voltage drop below a preset level, the
control board will signal the engine to crank and start.
When utility voltage is restored above a preset voltage level,
the engine is signaled to shut down.
The actual system operation is not adjustable and is
sequenced by sensors and timers on the control board,
as follows:
Utility Voltage Dropout Sensor
• This sensor monitors utility source voltage.
• If utility source voltage drops below about 70 percent
of the nominal supply voltage, the sensor energizes
a 3 second timer. The timer is used to ‘sense’
brown-outs.
• Once the timer has expired, the engine will crank
and start.
Utility Voltage Pickup Sensor
This sensor monitors utility voltage. When utility voltage is
restored above 80 percent of the nominal source voltage, a
time delay starts timing and the engine will go to engine cool-
down.
Engine Cool-down Timer
When utility power is sensed and the load transfers back to
the utility source, the engine will go into a cool down period
as described below:
• If the generator has run for MORE than 5 minutes,
once the utility transfer occurs, the engine will
continue to run for about 1 minute before shutting
down.
• If the generator has run for LESS than 5 minutes, once
the utility transfer occurs, the engine will continue to
run until 5 minutes has elapsed before shutting down.

Generator Maintenance
Generator maintenance consists of keeping the unit
clean. Operate the unit in an environment where it will
not be exposed to excessive dust, dirt, moisture or any
corrosive vapors. Cooling air louvers on the enclosure
must not become clogged with snow, leaves, or any other
foreign material. To prevent generator damage caused by
overheating, keep the enclosure cooling inlets and outlets
clean and unobstructed at all times.
Check the cleanliness of the unit frequently and clean when
dust, dirt, oil, moisture or other foreign substances are visible
on its exterior/interior surface. Inspect the air inlet and outlet
openings inside and outside the enclosure to ensure air flow
is not blocked.
DO NOT use direct spray from a garden hose to clean generator.
Water can enter the engine and generator and cause problems.
Cleaning the Generator
1. Turn the generator off.
2. Remove 15 Amp fuse from control board.
3. Clean generator as desired.
• Use a damp cloth to wipe exterior surfaces clean.
• Use a soft, bristle brush to loosen caked on dirt, etc.
• Use a vacuum cleaner to pick up loose dirt and debris.
• Use low pressure air (not to exceed 25 psi) to blow
away dirt. Inspect cooling air slots and openings on
the generator. These openings must be kept clean and
unobstructed.
4. Reinstall 15 Amp fuse in control board.
5. Turn the generator on and place in AUTO mode.
NOTICE Improper treatment of generator can damage it
and shorten its life.
• DO NOT expose generator to excessive moisture, dust,
dirt, or corrosive vapors.
• DO NOT insert any objects through cooling slots.
Engine Maintenance
The maintenance of an engine and related components are
critical to its operating performance and lifespan. Industrial
engines operate in an environment that often include hot
and cold temperatures and extreme dust. The recommended
maintenance schedule is listed in this section, however,
environmental operating conditions and additional installed
equipment may require more frequent inspection and
servicing. The owner and/or authorized service technician
should review the operating conditions of the equipment to
determine the inspection and maintenance intervals. Proper
engine cooling and lubrication are very important, so pay
particular attention to these matters.
Engine Oil
The engine is shipped from the factory pre-run and filled
with non-synthetic oil (API SL 10W-30). This allows for
system operation in a wide range of temperature and
climateconditions.
Oil Recommendation
Select and engine oil viscosity that will best match the
prevailing daytime temperature.
The oil must meet GM specification 9986231. Motor oils
meeting this spec receive the API (American Petroleum
Institure) starburst symbol:
HOT WEATHER
COLD WEATHER
SAE 10W-30
PREFERRED
SAE 15W-40
FOR THE BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURE RANGE
IF NEITHER SAE 10W-30
NOR SAE 15W-40 GRADE
OILS ARE AVAILABLE, SAE
30 GRADE MAY BE USED AT
TEMPERATURES ABOVE 4
DEGREES C (40F), SAE 40
GRADE AY BE USED AT
TEMPERATURES ABOVE 27
DEGREES C (80F).
DO NOT USE SAE 10W-40
GRADE OIL OR ANY OTHER
GRADE NOT RECOMMENDED
RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS
40°F (4°C)
It is noted that the GF-4 oils are also “backward compatible”
and are equal or better than previous grades of oil in all
aspects.
Synthetic Oils
Synthetic Oils have been available for use in industrial
engines for a relatively long period of time and may offer
advantages in cold and hot temperatures. However, it is not
known if synthetic oils provided operational or economic
benefits over conventional petroleum-based oils in industrial
engines. Use of synthetic oils does not permit the extension
of oil change intervals.

Engine Air Cleaner
Once each year service the air cleaner, as follows. If
operating in a dusty environment, service more often.
1. Turn the generator off.
2. Remove 15 Amp fuse from control panel.
3. Remove filter cartridge - Remove the service cover by
disengaging three clips and detaching cover, starting
with the bottom two clips and the top clip last. Gently
move the end of the filter back and forth, then rotate
while pulling straight out.
4. Clean outlet tube and check Vacuator™
valve - Use a clean cloth to wipe the
filter sealing surface and the outlet tube
surfaces. Make sure that all contaminant
is removed before the new filter is
inserted. Be careful to not damage the sealing area on
the tube.
Visually check and physically squeeze Vacuator valve
attached to service cover to make sure it is flexible and
not inverted, damaged orplugged.
5. Clean filter - Use a soft bristle brush to loosen dirt
and a vacuum cleaner to remove dirt and debris. Low
pressure air (not to exceed 25 psi) may also be used to
blow away dirt. Replace filter cartridge if any holes are
detected in filter media.
6. Install clean filter properly - Insert the filter carefully.
Seat the filter by hand, making certain it is completely
into the air cleaner housing before securing the cover
in place. To complete a tight seal, apply pressure by
hand at the outer rim of the filter, not the flexible center.
(Avoid pushing on the center of the urethane end cap.)
No cover pressure is required to hold the seal.
NEVER use the service cover to push the filter into
place! Using the cover to push the filter in could cause
damage to the housing, cover, or fasteners and will void
the warranty. If the service cover hits the filter before
it is fully in place, remove the cover and push the filter
(by hand) further into the air cleaner and try again. The
cover should go on with no extra force.
7. Reinstall service cover - Once the filter is in place,
reinstall the service cover, positioning the cover with
the arrow and the word TOP to the top. Fasten the top
clip first, the bottom two clips last. Make sure that all
mounting bands, clamps, bolts, and connections in the
entire air cleaner system are tight and verify absence of
holes in piping - repair if needed.
8. Replace 15 Amp fuse in control panel.
9. Turn the generator on.
