GENERAL HAZARDS
The engine exhaust from this product
contains chemicals known to the state
of California to cause cancer, birth
defects or other reproductive harm.
This product contains or emits chemicals
known to the state of California to cause
cancer, birth defects or other reproductive harm.
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.
WARNING:
WARNING:
DANGER
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 responsible
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 applicable
codes, standards, laws and regulations.
A running generator gives off carbon monoxide,
and odorless, colorless poison gas. Breathing in
carbon monoxide can cause headaches, fatigue,
diziness, nausea, vomitting, confusion, fainting,
siezures or death.
2
For safety reasons, the manufacturer recommends that this equip-•
ment 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.
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.
Adequate, unobstructed flow of cooling and ventilating air is •
critical to correct generator operation. Do not alter the installation or permit even par tial 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 par ts. Never remove any drive belt or
fan guard while the unit is operating.
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 par ts needing repair or replacement.
Before perfor ming any maintenance on the generator, discon-•
nect 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 par ts as a step. Stepping •
on the unit can stress and break par ts, and may result in dangerous operating conditions from leaking exhaust gases, fuel
leakage, oil leakage, etc.
ENGINE EXHAUST HAZARDS
Generator engine exhaust contains DEADLY carbon monox-•
ide, an odorless, colorless poisonous gas. Breathing carbon
monoxide can cause: dizziness, throbbing temples, nausea,
muscular twitching, headache, vomiting, weakness and sleepiness, inability to think clearly, fainting, unconsciousness or
even death. If you experience any carbon monoxide poisoning
symptoms, move into fresh air and immediately seek medical
attention.
Never operate the generator set with the vehicle inside any •
garage or other enclosed area.
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 sur face to reduce
shock hazard.
Do not handle any kind of electrical device while stand-•
ing 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 par ts 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 genera-•
tor 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 15A 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. Jewelr y •
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 depar tment with any questions per taining to fire extinguishers.
IMPORTANT SAFETY INSTRUCTIONS
Air-cooled Generators
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 compar tment, 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.

DANGER
Section 1 — General Information
Air-cooled Generators
Only qualified electricians or contractors should
attempt such installations, which must comply
strictly with applicable codes, standards and regulations.
1.1 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.
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 transfer
switch. The transfer switch must effectively isolate
the electrical system from the utility distribution
system when the generator is operating (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 deliver y, 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.
1.2 PROTECTION SYSTEMS
Unlike an automobile engine, the generator may have to run for
long periods of time with no operator present to monitor engine
conditions. For that reason, the engine is equipped with the following systems that protect it against potentially damaging conditions:
1. Low Oil Pressure Sensor
2. High Temperature Sensor
3. Overcrank
4. Overspeed
5. RPM Sensor
6. Low Battery
There are readouts on the control panel to notify personnel that one
of these failures has occurred. There is also a System Set LED
(single cylinder) or a Status message on the display (V-twins) that
displays when all of the conditions described in the "System Set
LED" section are true.
1.3 NEC REQUIREMENT FOR ARC FAULT
CIRCUIT INTERRUPTION BREAKER FOR
BEDROOMS
In 2001, the National Electric Code (NEC) introduced a requirement
for new construction. This new requirement indicates the need for
Arc Fault Circuit Interrupters to be used to protect the complete
branch circuit that feeds a dwelling bedroom. The actual NEC
requirement is indicated below.
1.3.1 SECTION 210.12 ARC FAULT CIRCUIT INTER -
RUPTER PROTECTION
1. Definition: An arc fault circuit interrupter is a device intended
to provide protection from the effects of arc faults by recognizing characteristics unique to arcing and by functioning to
de-energize the circuit when an arc fault is detected.
2. Dwelling Unit Bedrooms: All branch circuits that supply 125
volt, single-phase, 15 and 20 ampere outlets installed in
dwelling unit bedrooms shall be protected by an arc fault circuit interrupter listed to provide protection of the entire branch
circuit.
Section 210.12 requires that AFCI protection be provided on branch
circuits that supply outlets (receptacle, lighting, etc.) in dwelling bedrooms. The requirement is limited to 15 and 20 ampere,
125 volt circuits. There is no prohibition against providing AFCI
protection on other circuits or in locations other than bedrooms.
Because circuits are often shared between a bedroom and other
areas such as closets and hallways, providing AFCI protection on
the complete circuit would comply with 210.12.
If during the installation of the home standby system the decision
is made to provide back up power to a bedroom branch circuit,
then the circuit breaker in the transfer switch should be replaced
with an Arc Fault Circuit Interrupter.
It is most impor tant that breakers only be switched like for like.
For instance, if replacing a 15A breaker, it MUST be replaced with
a 15A AFCI breaker. Likewise, a 20A breaker MUST be replaced
with a 20A AFCI.
These AFCI breakers are available at the nearest hardware store.

1.7 SYSTEM SET LED
The “System Set” LED (single cylinder) or "Ready to Run" on the
display (v-twin) is ready when all of the following conditions are
true:
1. The AUTO/OFF/MANUAL switch is set to the AUTO position.
2. The utility voltage being supplied to the unit is being sensed
by the PCB. If the utility sense voltage is not connected to the
unit or if it is below approximately 150-160 volts AC, then the
system set light will flash rapidly (8kW). This indicates that if
the AUTO/OFF/MANUAL switch is placed in the Auto position,
the generator will star t.
3. No alarms are present, for example, low oil pressure, high
temperature, etc.
1.8 FUEL REQUIREMENTS
AND RECOMMENDATIONS
With LP gas, use only the vapor withdrawal system. This type of
system uses the vapors formed above the liquid fuel in the storage
tank.
The engine has been fitted with a fuel carburetion system that
meets the specifications of the 1997 California Air Resources
Board for tamper-proof dual fuel systems. The unit will run on
natural gas or LP gas, but it has been factory set to r un on natural
gas. Should the primary fuel need to be changed to LP gas, the
fuel system needs to be reconfigured. See the reconfiguring the
Fuel System section for instructions on reconfiguration of the fuel
system.
Recommended fuels should have a Btu content of at least 1,000
Btus per cubic foot for natural gas; or at least 2,520 Btus per
cubic foot for LP gas. Ask the fuel supplier for the Btu content of
the fuel.
Required fuel pressure for natural gas is five (5) inches to seven
(7) inches water column (0.18 to 0.25 psi); and for liquid propane, 10 inches to 12 inches of water column (0.36 to 0.43 psi).
The primary regulator for the propane supply is NOT INCLUDED
with the generator.
NOTE:
All pipe sizing, construction and layout must comply
with NFPA 54 for natural gas applications and NFPA
58 for liquid propane applications. Once the generator is installed, verify that the fuel pressure NEVER
drops below four (4) inches water column for natural
gas or 10 inches water column for liquid propane.
Prior to installation of the generator, the installer should consult
local fuel suppliers or the fire marshal to check codes and regulations for proper installation. Local codes will mandate correct routing of gaseous fuel line piping around gardens, shrubs and other
landscaping to prevent any damage.
Special considerations should be given when installing the unit
where local conditions include flooding, tornados, hurricanes,
ear thquakes and unstable ground for the flexibility and strength of
piping and their connections.
Use an approved pipe sealant or joint compound on all threaded
fitting.
All installed gaseous fuel piping must be purged and leak tested
prior to initial star t-up in accordance with local codes, standards
and regulations.

Gaseous fuels such as natural gas and liquid
propane (LP) gas are highly explosive. Even the
slightest spark can ignite such fuels and cause
an explosion. No leakage of fuel is permitted.
Natural gas, which is lighter than air, tends to
collect in high areas. LP gas is heavier than air
and tends to settle in low areas.
A minimum of one approved manual shut-off valve
must be installed in the gaseous fuel supply line. The
valve must be easily accessible. Local codes determine the proper location.

1.10 RECONFIGURING THE FUEL SYSTEM
1.10.1 8 KW, 410CC ENGINE
To reconfigure the fuel system from NG to LP, follow these steps
(Figure 1.4):
NOTE:
The primary regulator for the propane supply is NOT
INCLUDED with the generator. A fuel pressure of 10
to 12 inches of water column (0.36 to 0.43 psi) to the
fuel inlet of the generator MUST BE SUPPLIED.
1. Turn off the main gas supply (if connected).
2. Open the roof and remove the door.
3. Remove the battery (if installed).
4. Take the plastic T-handle fuel selector in the poly bag supplied
with the generator.
5. Locate the selector knob on the air box cover, behind the
yellow air filter door and power bulge. The unit comes from
the factory in the NG (Natural Gas) position. Grasping the
T-handle, insert the pin end into the hole in the selector knob
and pull out to overcome spring pressure and then twist
clockwise 90 degrees and allow the selector to return in once
aligned with the LP (Liquid Propane) position.
6. Save this tool with the Owner's Manual.
7. Install the battery, door and close the roof.
8. Reverse the procedure to convert back to natural gas.

Allow sufficient room on all sides of the generator for mainte-•
nance and servicing. This unit must be installed in accordance
with current applicable NFPA 37 and NFPA 70 standards; as
well as any other federal, state and local codes for minimum
distances from other structures. DO NOT install under wooden
decks or structures unless there is at least four (4) feet of clearance above the generator, three (3) feet of clearance on sides
and front, and 18 inches of clearance at back of unit.
Install the unit where rain gutter down spouts, roof run-off, •
landscape irrigation, water sprinklers or sump pump discharge
does not flood the unit or spray the enclosure, including any air
inlet or outlet openings.
Install the unit where services will not be affected or obstructed, •
including concealed, underground or covered services such as
electrical, fuel, phone, air conditioning or irrigation.
Where strong prevailing winds blow from one direction, face the •
generator air inlet openings to the prevailing winds.

1.11 LOCATION
1.11.1 GENERATOR
Install the generator set, in its protective enclosure, outdoors,
where adequate cooling and ventilating air is always available
(Figure 1.9). Consider these factors:
The installation of the generator • must comply strictly with
NFPA 37, NFPA 54, NFPA 58, and NFPA 70 standards.
Install the unit where air inlet and outlet openings will not •
become obstructed by leaves, grass, snow, etc.. If prevailing
winds will cause blowing or drifting, consider using a windbreak to protect the unit.
Install the generator on high ground where water levels will not •
rise and endanger it.
10
Install the generator as close as possible to the fuel supply, to •
reduce the length of piping.
Install the generator as close as possible to the transfer switch. •
REMEMBER THAT LAWS OR CODES MAY REGULATE THE
DISTANCE AND LOCATION.
The genset must be installed on a level surface. The base frame •
must be level within two (2) inches all around.
The generator is typically placed on pea gravel or crushed •
stone. Check local codes if a concrete slab is required. If a
concrete base slab is required, all federal, state and local codes
should be followed. Special attention should be given to the
concrete base slab which should exceed the length and width
of the generator by a minimum of six (6) inches (0.152 meters)
on all sides.
