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

This product contains or emits chemicals known to the

State of California to cause cancer, birth defects and

other reproductive harm.

• 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

required permits before starting the job.

NOTE:

Failure to follow these minimum clearance guidelines may result in the generator failing inspection by the local

building, electrical or fire inspector requiring the generator be reinstalled in the correct location.

MINIMUM CLEARANCE REQUIREMENTS

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.

Hose

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

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

breaker panel. Remove the plastic hole plug from the conduit

connector plate.

4. Pass all wires through hole in conduit connector plate, insert

conduit connector, and place lock nut onto conduit connector.

5. Support the conduit connector plate up towards the output

circuit breaker. Make all the required wiring connections to the

Circuit breaker, Neutral Bar, Ground bar and Terminal strips

as described on the decal on the back side of the dead front

plate.

NOTE:

In order to maintain separation of circuits, the DC control wires

must be separated from the AC control wires. A piece of fiber-

glass sleeving has been provided in the manual kit to achieve

this. Slide the sleeving over the AC wires OR the DC wires, but

not both. Sleeving should extend over the wires from the conduit

connector in the conduit plate up to the terminal blocks.

6. Once all connections are made, reattach the conduit

connector plate to the output circuit breaker panel making

sure no wires are trapped behind the panel.

7. Reattach the dead front plate to the output circuit breaker

panel with hardware removed in Step 1. Make sure to

reconnect the grounding wire.

generator through the slot in the dead front plate. Push the

padlock hasp back until it clicks and locks into place.

9. To complete the external electrical connections snap in the

output circuit breaker cover that is supplied loose with the

generator into the output circuit breaker panel. Allow the cover

to swing down providing weather protection for the circuit

breaker.

The padlock hasp will now protrude through the circuit

breaker cover and it is recommended that once installation

of the generator is completed a padlock be used to provide

suitable security to the generator.

BATTERY INSTALLATION

The correct size battery for this generator that will fit easily and

provide the required starting ability is any maintainable automotive

style group 26R with a minimum of 525 CCA @ 0 deg F.



Before attempting to install the battery make

sure the auto/off/manual switch is in the off

position. Remove the main fuse from the
