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 can 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

can create hazards or hamper rescue or fire-fighting

operations.

9

Generator Placement

Before installing the generator, consult with the owner

and convey the following requirements, which must be

satisfied before the installation is complete. There are two

equally important safety concerns in regards to carbon

monoxide poisoning and fire. There are also several general

location guidelines that must be met before the installation is

considered complete.

WARNING



Engine exhaust contains carbon monoxide, a

poisonous gas that could kill you in minutes. You cannot

smell it, see it, or taste it. Even if you do not smell exhaust

fumes, you could still be exposed to carbon monoxide gas.

• Operate this product ONLY outdoors in an area that will

not accumulate deadly exhaust gas.

• Direct exhaust gas away from any windows, doors,

ventilation intakes, soffit vents, crawl spaces, open

garage doors or other openings that can allow exhaust

gas to enter inside or be drawn into a potentially

occupied building or structure.

• Carbon monoxide detector(s) MUST be installed and

maintained indoors according to the manufacturer’s

instructions/recommendations. Smoke alarms cannot

detect carbon monoxide gas.

• If you start to feel sick, dizzy, weak, or your carbon

monoxide alarm sounds while using this product, get to

fresh air right away. Call emergency services. You may

have carbon monoxide poisoning.



• DO NOT run this product inside homes, garages,

basements, crawlspaces, sheds, or other partially-

enclosed spaces even if using fans or opening doors and

windows for ventilation. Carbon monoxide can quickly

build up in these spaces and can linger for hours, even

after this product has shut off.

• ALWAYS place this product downwind and point the

engine exhaust (A) away from occupied spaces.

 (A) Exhaust outlet side of enclosure.

 (B)Air inlet side of enclosure.

Generator Location Considerations

The installation location of the generator has a direct effect

on:

1. The amount and size of the plumbing required to fuel the

generator.

2. The amount and size of the wiring required to control and

connect the generator.

3. The safety of the installation regarding exhaust gas and

carbon monoxide hazards, fire risks, proximity to other

utilities, and exposure to weather elements.

Specific location guidelines are discussed in the next

section. The owner and installer must consult one another

to determine how the site can affect installation costs and

compliance with local codes andstandards.

There are two critical safety concerns to be addressed -

carbon monoxide poisoning and the risk of fire, as follows:

Reduce the Risk of Carbon Monoxide Poisoning

The arrows in the figure below point to potential points of entry for Carbon Monoxide Gas.



10

All fossil fuel burning equipment, such as standby generators (A), contains carbon monoxide (CO) gas in the engine exhaust

(H). CO gas is odorless, colorless and tasteless and is unlikely to be noticed until a person is overcome. CO gas can kill you

so it is required that the following is included as part of the installation.

• Install generator (A) outdoors in an area that will not accumulate deadly exhaust gas (H).

• DO NOT install the generator (A) where exhaust gas (H) can accumulate and enter inside or be drawn into a potentially

occupied building or structure.

• In many states it is required by law to have a Carbon Monoxide (CO) detector that works in your home. Carbon monoxide

detector(s) MUST be installed and maintained indoors according to the manufacturer’s instructions / recommendations. A

CO detector is an electronic device that detects hazardous levels of CO. When there is a buildup of CO, the detector will

alert the occupants with an alarm and by flashing a visual indicator light. Smoke alarms cannot detect CO gas.

• Your neighbor(s) home can be exposed to the engine exhaust (H) from your standby generator (A) and must be

considered when installing your standby generator.

• Make sure exhaust gas (H) is kept away from:

(B) Windows

(C) Doors

(D) Ventilation Intakes

(E) Soffit Vents

(F) Garage Doors

(G)Crawl spaces or other openings that can allow exhaust gas to enter inside or be drawninto a potentially occupied building

or structure.



11

• Nearby structures may be exposed to the engine exhaust (H) from the generator (A) and must be considered when

installing the standby generator.

• Wind and air currents should be taken into consideration when positioning the generator (A). Place the generator in an

area where winds will carry the exhaust gas (H) away from any potentially occupied building or structure.

• DO NOT place the standby generator (A) in any area where leaves or debris can accumulate.

Reduce The Risk of Fire

Obey the installation requirements listed below. The figures below illustrate the minimum distances from structures and

vegetation to reduce the risk of fire.

The National Fire Protection Association (NFPA) standard NFPA 37 establishes criteria for minimizing the hazard of fire

during the installation and operation of stationary combustion engines. NFPA 37 limits the spacing of an enclosed generator

from openings in walls, structures and combustible materials outside the enclosure. The following generator placement

requirements are based on compliance to NFPA 37.



WARNING

Exhaust heat/gases could ignite combustibles or structures resulting in death or serious injury.

• Exhaust outlet of enclosure must have at least 5 ft. (1.5m) minimum clearance from any structure, shrubs, trees, or any

kind of vegetation.

• Enclosure must be at least 5 ft (1.5m) from windows, doors, any wall opening, shrubs, or vegetation over 12 inches (30.5

cm) in height.

• Enclosure must have a minimum of 5 ft. (1.5 m) overhead clearance from any structure, overhang, or trees.

• DO NOT place enclosure under a deck or other type of structure that may confine airflow.

• Smoke detector(s) MUST be installed and maintained indoors according to the manufacturer’s instructions. Carbon

monoxide alarms cannot detect smoke.

• Do not place enclosure in a manner other than shown in illustrations.

(E)Standby enclosure must have a minimum of 18 inches (45.7 cm) clearance from any structures with or without a fire

rating.

Other General Location Guidelines

• Place the standby generator in a prepared location that is

flat and has provisions for water drainage.

• Install the standby generator in a location where sump

pump discharge, rain gutter down spouts, roof run-off,

landscape irrigation, or water sprinklers will not flood the

unit or spray the enclosure and enter any air inlet or outlet

openings.

• Install the standby generator where it will not affect or

obstruct any services (including covered, concealed and

underground), such as telephone, electric, fuel (natural

gas / LPG vapor), irrigation, air conditioning, cable, septic,

sewer, well and so forth.

• Install the standby generator where leaves, grass, snow,

etc will not obstruct air inlet and outlet openings. If

prevailing winds will cause blowing or drifting, you may

need to construct a windbreak to protect the unit.

Fuel Installation Plan

WARNING

Propane and Natural Gas are extremely flammable

and explosive, which could cause burns, fire or explosion

resulting in death or serious injury.

• Installation must be performed by a licensed

professional.

• Install the fuel supply system according to NFPA 37 and

other applicable fuel-gas codes.

• Before placing the generator into service, the fuel

system lines must be properly purged and leak tested.

• NO leakage is permitted.

• DO NOT operate engine if smell of fuel is present.



NOTICE The supplied flexible fuel line is not to be

installed underground or in contact with the ground.

• The entire flexible fuel line must be visible for periodic

inspection and must not be concealed within nor contact

nor run through any wall, floor, or partition.

The information below is provided to assist gaseous fuel

system technicians in planning installations. In no way

should this information be interpreted to conflict with

applicable fuel gas codes. Consult with your local fuel

supplier or Fire Marshall if questions or problems arise.



WARNING

Propane and Natural Gas are extremely flammable

and explosive, which could cause burns, fire or explosion

resulting in death or serious injury.

• The generator is equipped with an automatic safety

gasfuel shut-off valve.

• DO NOT operate the equipment if the fuel shut-off valve

is missing or inoperative.

17

WARNING

Propane and Natural Gas are extremely flammable

and explosive, which could cause burns, fire or explosion

resulting in death or serious injury.

• LP gas is heavier than air and will settle in low areas.

• Natural gas is lighter than air and will collect in high

areas.

• The slightest spark could ignite these fuels and cause

an explosion.

• DO NOT light a cigarette or smoke.



TO THE INSTALLER:Consult with the generator owner(s)

and convey any technical considerations that can affect their

installation plans before applying these general guidelines.

The following general rules apply to gaseous fuel system

piping:

• The piping material must conform to federal and local

codes, be rigidly mounted, and be protected against

vibration.

• Piping should be protected from physical damage,

especially where it passes through flower beds, shrub

beds, and other cultivated areas where damage can

occur.

• Install the provided flexible fuel line (B) between the

generator fuel inlet port (A) and the rigid piping to

prevent thermal expansion and contraction from causing

excessive stress on the piping material.

• A union (C) or a flanged connection must be provided

downstream to permit removal.

• A manometer test port (D) should be installed for

vapor fuels. Use the port to install a manometer and

check if the engine receives the correct fuel pressure

for operation. A digital manometer (P/N 19495) or an

analogmanometeris available at your service center for

vapor fuels only. When the initial test runs are completed,

the manometer is removed and the port is plugged.

• For vapor fuels only: Where the formation of hydrates or

ice is known to occur, piping should be protected against

freezing. The termination of hard piping must include

a sediment trap (E) where condensate is not likely to

freeze.

• A minimum of one accessible, approved manual shutoff

valve (F) shall be installed in the fuel supply line within 6

ft (180 cm) of the generator.

• You must install a manual fuel shut-off valve in the interior

of the building.

• Where local conditions include earthquake, tornado,

unstable ground, or flood hazards, special consideration

shall be given to increase strength and flexibility of piping

supports and connections.

• Piping must be of the correct size to maintain the

required supply pressures and volume flow under

varying generator load conditions with all gas appliances

connected to the fuel system turned on andoperating.

• Use a pipe sealant or joint compound approved for

use with NG/LP on all threaded fittings to reduce the

possibility of leakage.

NOTICE Keep thread sealant out of the gas piping to

prevent component part damage.

• Installed piping must be properly purged and leak tested,

in accordance with applicable codes andstandards.

Fuel Type

An important consideration affecting the entire installation

is the type of fuel used by your generator. The system was

factory tested and adjusted using natural gas, but can be

converted to use LP vapor. For correct engine function,

factors that are inherent to each of these fuels, like your

location and the duration of possible utility interruptions, are

important considerations in the following fuel guidelines:

• Use clean, dry fuel that is free of moisture or

any particulate material. Using fuels outside the

recommendation values that follow can 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% is required.

Natural gas rating will depend on specific fuel, but typical

derates are between 10 and20% of the LP gas rating.

Natural gas or LP engines are certified to operate on natural

or liquid propane gas. The emissions control system for this

engine is EM (Engine Modifications).

Fuel Pressure

Both LP vapor and natural gas fuel supply pressure at the

generator’s fuel inlet port and must be between the following

levels at full load with all gas appliances turned on and in

operation.

• NG is 3.5-7” W.C.

• LP is 11-14” W.C.

Make sure that all gas line shutoff valves are OPEN and

that adequate fuel pressure is available whenever automatic

operation is desired.

For Natural Gas fuel pressure levels of 3.5 - 5" W.C., replace

the regulator assembly with service kit 6331-00 (available at

your local service dealer).

Power Loss

Air density is less at high altitudes, resulting in less available

engine power. Engine power will decrease by 3.5% for each

1,000 feet (300 m) above sea level and by 1% for each

10° F (5.6°C) above 77°F (25°C). Generators located in

these conditions must have their transfer switch adjusted

appropriately for this power decrease. See your Automatic

Transfer Switch manual on how to adjust for the power

decrease.

The Gaseous Fuel System

Fuel Pipe Sizing

NFPA 54 and 58 are common resources. The installer must

consider the specific gravity of gas, compensate for a nominal

amount of restriction from bends and fittings, and refer to

federal and local codes for guidance.

Fuel Conversion

The engine of your home generator system is factory

Calibrated and set to operate on natural gas (NG). It may also

be operated on liquefied petroleum (LP) vapor.



NOTICE Units are set to NG at the factory.
