SAFETY RULES
Save These Instructions – The manufacturer
suggests that these rules for safe operation
be copied and posted near the unit’s instal-
lation site. Safety should be stressed to all
operators and potential operators of this
equipment.
Study these SAFETY RULES carefully before installing, operating
or servicing this equipment. Become familiar with this Owner’s
Manual and with the unit. The generator can operate safely,
efficiently and reliably only if it is properly installed, operated and
maintained. Many accidents are caused by failing to follow simple
and fundamental rules or precautions.
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.
Despite the safe design of this generator,
operating this equipment imprudently,
neglecting its maintenance or being careless
can cause
possible injury or death. Permit only respon-
sible and capable persons to install, operate
and maintain this equipment.
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.
Installation must always comply with applica-
ble codes, standards, laws and regulations.
A running generator gives off carbon mon-
oxide, an odorless, colorless poison gas.
Breathing in carbon monoxide can cause
headaches, fatigue, diziness, nausea, vomit-
ting, confusion, fainting, siezures or death.
GENERAL HAZARDS
For safety reasons, the manufacturer recommends that this
equipment be installed, serviced and repaired by a Service
Dealer or other competent, qualified electrician or installation
technician who is familiar with applicable codes, standards
and regulations. The operator also must comply with all such
codes, standards and regulations.
Adequate, unobstructed flow of cooling and ventilating air
is critical to correct generator operation. Do not alter the
installation or permit even partial blockage of ventilation
provisions, as this can seriously affect safe operation of the
generator. The generator MUST be installed and operated
outdoors only.
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.
CALIFORNIA PROPOSITION 65 WARNING
Engine exhaust and some of its constituents are known
to the State of California to cause cancer, birth defects
and other reproductive harm.
CALIFORNIA PROPOSITION 65 WARNING

When working on this equipment, remain alert at all times.
Never work on the equipment when physically or mentally
fatigued.
Inspect the generator regularly, and contact the nearest Dealer
for parts needing repair or replacement.
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, then remove the POSITIVE, POS
or (+) cable. When reconnecting the cables, connect the
POSITIVE cable first, the NEGATIVE 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.
CARBON MONOXIDE HAZARDS
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.
Do NOT alter or add to the exhaust system or do anything that
might render the system unsafe or in noncompliance with
applicable codes and standards.
Install a battery operated carbon monoxide alarm indoors,
according to manufacturer’s instructions/recommendations.
ELECTRICAL HAZARDS
All generators covered by this manual produce dangerous
electrical voltages and can cause fatal electrical shock. Utility
power delivers extremely high and dangerous voltages to
the transfer switch as does the standby generator when it
is in operation. Avoid contact with bare wires, terminals,
connections, etc., while the unit is running. Ensure all
appropriate covers, guards and barriers are in place, secured
and/or locked 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.
The National Electrical Code (NEC) requires the frame and external
electrically conductive parts of the generator to be connected to
an approved earth ground. Local electrical codes also may require
proper grounding of the generator electrical system.
After installing this home standby electrical system, the
generator may crank and start at any time without warning.
When this occurs, load circuits are transferred to the STANDBY
(generator) power source. To prevent possible injury if such
a start and transfer occur, always set the generator’s AUTO/
OFF/MANUAL switch to its OFF position before working on
equipment and remove the 7.5A fuse from the generator control
panel.
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 dry 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.
FIRE HAZARDS
For fire safety, the generator must be installed and maintained
properly. Installation must always 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 near the generator at all times.
Extinguishers rated “ABC” by the National Fire Protection
Association are appropriate for use on the standby electric
system. Keep the extinguisher properly charged and be
familiar with its use. Consult the local fire department with any
questions pertaining to fire extinguishers.
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.
Gaseous fluids such as natural gas and liquid propane (LP)
gas are extremely EXPLOSIVE. Install the fuel supply system
according to applicable fuel-gas codes. Before placing the
home standby electric system into service, fuel system
lines must be properly purged and leak tested according to
applicable code. After installation, inspect the fuel system
periodically for leaks. No leakage is permitted.

UNPACKING/INSPECTION
After unpacking, carefully inspect the contents for damage.
This standby generator set is ready for installation with a factory
supplied and pre-mounted base pad and has a weather protective
enclosure that is intended for outdoor installation only.
This UL listed standby generator set is packaged with an
automatic transfer switch with built in load center.
This UL listed, 2-pole transfer switch is rated at 50A AC
amperes at 250 volts maximum.
If this generator is used to power electrical load
circuits normally powered by a utility power
source, it is required by code to install a trans-
fer switch. The transfer switch must effectively
isolate the electrical system from the utility dis-
tribution system when the generator is operat-
ing (NEC 700, 701 & 702). Failure to isolate an
electrical system by such means will result in
damage to the generator and also may result in
injury or death to utility power workers due to
backfeed of electrical energy.
If any loss or damage is noted at time of delivery, have the
person(s) making the delivery note all damage on the freight bill
or affix their signature under the consignor’s memo of loss or
damage.
If a loss or damage is noted after delivery, separate the damaged
materials and contact the carrier for claim procedures.
“Concealed damage” is understood to mean damage to the
contents of a package that is not in evidence at the time of
delivery, but is discovered later.
To properly open the roof, press down on the center top lip and
release the latch. If pressure is not applied from the top, the roof
may appear stuck. Always verify that the side lock is unlocked
before attempting to lift the roof.
BEFORE YOU BEGIN
Contact the local inspector or City Hall to be aware of all federal,
state and local codes that could impact the installation. Secure all

SITE PREPARATION AND GENERATOR
PLACEMENT
1. Locate the mounting area as close as possible to the transfer
switch and fuel supply.
Leave adequate room around the area for service access
(check local code), and place high enough to keep rising
water from reaching the generator.
Choose an open space that will provide adequate and
unobstructed airflow. Do not install under or too close to
partially enclosed spaces including, but not limited to, decks
or buildings.
2. Place the unit so air vents won’t become clogged with leaves,
grass, snow or debris. Make sure exhaust fumes will not enter
the building through eaves, windows, ventilation fans or other
air intakes.
Dig a rectangular area approximately five inches deep and
about six inches longer and wider than the footprint of the
generator. Cover with polyurethane film and fill with pea gravel
or crushed stone. Compact and level the stone. A concrete
pad can be poured, or a Gen-Pad can be purchased if desired.
3. Set the generator onto the pad so that the gravel bed extends
several inches beyond the generator on all sides.
Make sure the generator is level within ½ inch.
4. The engine generator is to be grounded in accordance with
the NEC and local electrical codes.
5. Check the engine oil and, if necessary, add enough of the
recommended oil to bring the level up to the FULL mark on
the dipstick. Be careful not to overfill the crankcase.

CONVERTING TO LP VAPOR
1. Remove the generator enclosure roof by turning the four
quarter turn latches on the roof top. Push down slightly on the
latch then turn 90 degrees to release. The latch should pop up
as shown.
\2. Remove the two side panels of the enclosure by lifting the
panels straight up until they are clear.
3. Carefully place the roof and side panels to one side.
4. Locate the fuel throttle assembly mounted to the engine
intake.
5. To change the fuel selection, remove the hose clamp and
hose from the throttle assembly.
6. Remove the Natural Gas (Larger ID) fuel jet from the fuel inlet.
7. Obtain the fuel jet for Propane (Smaller ID that has been
supplied loose with the owners manual).
8. Verify that the O-ring, supplied loose with the owners manual
is installed, into the groove of the fuel jet.
9. Insert the Propane fuel jet into the end of the fuel inlet.
10. Reinstall the hose and clamp onto the fuel inlet and secure.
11. Verify the hose has not been kinked in any way.

12. The generator is now ready to run on LP Vapor fuel.
INSTALLING & CONNECTING GAS LINES
1. Both natural gas and LP Vapor are highly volatile substances,
so strict adherence to all safety procedures, codes, standards
and regulations is essential.
Gas line connections should be made by a certified plumber
familiar with local codes. Always use AGA-approved gas pipe
and a quality pipe sealant or joint compound.
Verify the capacity of the natural gas meter or the LP tank in
regards to providing sufficient fuel for both the generator and
other operating appliances.
Remove Clamp
and Hose
7
2. Most applications will require an external manual full flow
shutoff valve on the fuel line.
3. Where the gas line is to enter the generator enclosure. Install
a 3 - 5“ long piece of ½” black iron pipe threaded at both
ends (Not provided). Thread one end into the generator fuel
regulator using the reducing bushing provided. On the other
end of the pipe thread a ½” standard pipe Tee as shown (Not
provided).
4. Make sure the center leg of the Tee is pointing straight down
when fully tightened onto the pipe.
5. Thread a 3 – 4” long piece of ½” black iron pipe threaded
at both ends (not provided) into the Tee Fitting. Fully tighten.
Thread a ½” Pipe cap (not provided) to the other end of the
pipe. Fully tighten. This downward pointing pipe will serve as
a water and sediment trap and should be periodically emptied
once the generator is in service.
6. When connecting the gas line to the generator, use the
provided section of UL Listed or AGA-approved flexible fuel
line in accordance with local regulations. The purpose of the
flexible fuel line is to ensure that vibration from the generator
does not cause a gas leak at one of the connection points, so
it’s important that the line be installed with as few bends as
possible.
7. Never bend the flexible fuel line to avoid using an elbow.
Bending the flexible line decreases its ability to absorb
vibrations and defeats its purpose as well as constricts the
actual fuel flow.
8. After checking for leaks, check the gas pressure at the
regulator to make sure there’s enough pressure for proper
generator operation.
The local gas supplier is responsible for ensuring adequate
pressure, so if the pressure is too low, or if it’s greater than
14 inches of water column, contact the gas supplier.
Correct static fuel pressure should be:
Natural Gas = 5-7 inches water column
LP = 10-12 inches water column
9. When finished checking the gas pressure, close the manual
shutoff valve.
Measure fuel
pressure here.

EXTERNAL ELECTRICAL CONNECTIONS
1. Electrical Connections to the generator are to be made inside
the main output circuit breaker panel. The connections will
consist of the following:
2 x Ungrounded conductors – Minimum wire size use 75
Deg C, 300V wire, 10AWG Copper.
1 x Grounded Conductor - Minimum wire size use 75 Deg
C, 300V wire, 10AWG Copper.
1 x Equipment Grounding Conductor - Minimum wire size
use 75 Deg C, 300V wire, 10AWG Copper.
6 x Control Wires – Use 75 Deg C, 300V wire, 14AWG
Copper.
NOTE:
Either use different colored wires or identify both ends of the
wires for easy connection of all wires to the Transfer Switch.
NOTE:
Local codes may require the control wires to be run in a sepa-
rate conduit than the power wires.
Use Class 1 wiring methods.
These conductors should be fed through ¾” Flexible Liquid-
tight conduit for easy connection to the generator.
2. Remove the dead front plate from the output circuit breaker
panel. Retain fastener and external tooth washer for
reassembly.
3. Remove the conduit connector plate from the output circuit

2. Attach fuel pressure gauge to test point on fuel regulator.
3. Replace the fuse in the generator control panel and place the
switch into the manual position which will start the engine.
4. Allow the generator to warm up. Move the generator main
circuit breaker to the ON or CLOSED position. Generator
power is now being supplied to the transfer switch.
5. Check voltage and frequency of generator output at the
transfer switch terminals. Line to Line voltage should be
240V (+/- 10 VAC) and line to neutral voltage should be
approximately120V. Frequency should be 62 – 63Hz. If either
the voltage or frequency are incorrect refer to the owners
manual for instructions on how to adjust.
6. Once the voltage and frequency of the generator output have
been confirmed and are correct move the generator main
output breaker to the OFF or OPEN position and move the
control panel switch to the off position.
7. Manually move the transfer switch mechanism into the utility
position. i.e Circuit breaker connected to 50A utility breaker
should be closed.
8. Move the 2-pole 50A circuit breaker mounted in the main
