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 home

generator system installations. Installations must strictly

comply with all applicable codes, industry standards

and regulations.

Your home 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.

For the Home 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 home

generator installation.

To arrange for proper installation, contact the store at which

you purchased your home generator, your dealer, a licensed

electrician or your utility power provider.

The home 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.

The Emission Control System for this generator is warranted

for standards set by the U.S. Environmental Protection

Agency and by the California Air Resources Board (CARB).

For the Installing Dealer/Contractor:

For most applications, the Installation manual contains

all the information required to properly install and start

the home generator. This operator’s manual describes

essential circuit selection, routine operation and owner

maintenance procedures.

If you need more information in this matter, please call

(800) 743‑4115, between 8:00 AM and 5:00 PM CT.

Owner Orientation

This section provides home 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 home 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 home generator installation.

In some areas you may need to acquire electrical permits for

installing the home 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.

Fuel Factors

An important consideration affecting the entire installation is

the type of fuel used by your home 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.

WARNING Propane and Natural Gas are extremely

flammable and explosive.

Fire or explosion can cause severe burns

or death.

The home 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.

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 3.5%

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.

Generator Location

The actual physical location of your home generator has a

direct affect on:

1. The amount of plumbing required to fuel

your generator.

2. The amount of wiring required to control and connect

your generator.

Specific location guidelines are discussed in the installation

manual. Acquaint yourself with that information and confer

with your installer. Be sure to ask how your site might

affect installation costs and compliance with local codes

and standards.

The generator must be installed outdoors. DO NOT install

generator where exhaust gas could accumulate and enter

inside or be drawn into a potentially occupied building.

Ensure exhaust gas is kept away from any windows, doors,

ventilation intakes or other openings that can allow exhaust

gas to collect in a confined area. Prevailing winds and air

currents should be taken into consideration when positioning

generator. See the installation manual for full details on safe

generator location.

Essential Circuits

As a home generator owner, it is important that you clearly

identify the circuits in your building that are “essential” to

you. Your installer will then know which circuits you want

to include as “Essential Circuits”. Depending on the power

consumed by these circuits, most or all of them can be

switched to the home generator for the duration of normal

power interruption.

The wattage reference table that follows will assist you with

your decision-making process. It provides the wattage used

by many ordinary household devices. Use it when selecting

your essential circuits. Review this information with your

installer and ask about any technical considerations that

might affect your installation. This chart serves as a guide

only. For exact wattage use an appropriate wattage meter.

WARNING Running engine gives off carbon monoxide,

an odorless, colorless, poison gas.

Breathing carbon monoxide can cause headache,

fatigue, dizziness, vomiting, confusion, seizures,

nausea, fainting or death.

Operate generator ONLY outdoors.•

Install a battery operated carbon monoxide alarm near •

the bedrooms.

Keep exhaust gas from entering a confined area through •

windows, doors, ventilation intakes, or other openings.

WARNING Exhaust heat/gases can ignite combustibles

or structures causing a fire.

DO NOT install the generator closer than 5 feet (1.5m) •

from any combustibles or structures with combustible

walls having a fire resistance rating of less than 1 hour.

Essential Circuit Selection

When selecting the essential circuits that will be switched

to “Standby Power,” it is important that the sum of the

combined circuit loads does not exceed the wattage/

amperage capacity of the generator. To help you with your

selection of essential circuits, please consider the following:

 • Addupthetotalwattageofallelectricaldevicestobe

connected at one time. This total should NOT be greater

than the generator’s wattage capacity.

The rated wattage of lights can be taken from light

bulbs. The rated wattage of tools, appliances and

motors can usually be found on a data plate or label

affixed to the device.

 • Iftheappliance,toolormotornameplatedoesnot

list wattage, multiply volts times the ampere rating to

determine watts (Volts x Amps = Watts).

Some electric motors (induction types) require about

three times more watts of power for starting than for

running. This surge lasts for only a few seconds. Be

sure you allow for this high starting wattage when

selecting electrical devices that will be energized by the

home generator:

  • Figurethewattsrequiredtostartthelargestmotor.

  • Addthattothetotalrunningwattsofallother

connected loads.

This generator complies with the following “stationary

standby power rating”:

The standby power rating is applicable for supplying

power for the duration of normal power interruption. No

sustained overload capability is available for this rating.

This rating is applicable to installations served by

a reliable normal utility source. This rating is only

applicable to variable loads with an average load factor

of 80% of the standby rating. The standby rating is

only applicable for optional standby power where

the generator set serves as the backup to the normal

utility source.

Use the wattage reference table provided and mark those

circuits you consider “critical” or “essential”. Make sure you

and your installer consider the system’s altitude above sea

level and the ambient temperature range when determining

total generator load.

This engine is shipped from the factory filled with a

50-50 mix of automotive (Dex-Cool™ orange) anti-freeze

and water. This will provide optimum year round protection

against freezing, boiling and corrosion. The coolant system

incorporates a water heater that operates when ambient

temperature is below 80ºF AND utility power is present at

the transfer switch. Before starting the engine, check coolant

level as described in the engine operator’s manual.

Battery

The installer must supply a valve-regulated, rechargeable

12 volt DC starting battery. See Battery in Final Installation

Considerations in the installation manual.

With the battery installed, all wiring to transfer switch and

generator completed, utility power supplied to the automatic

transfer switch, and the unit in AUTO mode, the battery

receives a trickle charge while the engine is not running. The

trickle charge cannot be used to recharge a battery that is

completely discharged.

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.

Automatic Operation

To select automatic operation, do the following:

1. Confirm 15 Amp fuse is installed in control panel.

2. Set the main distribution panel circuit breaker that

sends utility voltage to the transfer switch to ON.

3. Set the generator’s circuit breaker to its ON position.

4. Set the control panel system switch to AUTO.

Checking Automatic Operation

To check the system for proper automatic operation, proceed

as follows:

1. Turn OFF the service disconnect or main distribution

panel circuit breaker sending power to the automatic

transfer switch.

When utility voltage is lost and the sensor has timed

out, the engine will crank and start. Let the system go

through its entire automatic operation sequence.

2. With the generator output supplying its loads, turn ON

the service disconnect or main distribution panel circuit

breaker that supplies utility power to the automatic

transfer switch.

3. The automatic transfer switch will transfer loads back

to utility power after a 5 minute minimum run time and

utility power is available.

4. The generator will run for an additional one minute for

engine cool down, then shut down.

If utility power is restored and generator does not shut down

after 10 minutes, set system switch to OFF and contact your

installer or local service center.

This completes the test procedures for automatic operation.

The home generator will now start automatically and will

supply power to the transfer switch when utility power

is lost.

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.

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 • Maintenance in the operator’s manual and engine

manual for coolant and oil fill information.

Damage to equipment resulting from failure to follow this •

instruction will void engine and generator warranty.

CAUTION With the system switch set to AUTO,

the engine may crank and start at any time

without warning.

To prevent possible injury that may be caused by such •

sudden starts, always set the system switch to OFF if

performing maintenance on the system.

Remove the 15 Amp fuse before working on or around •

the generator or transfer switch.

Setting Exercise Timer

The home generator is equipped with an exercise timer that

will start and exercise the system once every seven days.

During this exercise period, the unit runs for approximately

20 minutes and then shuts down. Electrical load transfer

DOES NOT occur during the exercise cycle (unless an utility

power outage occurs).

A button on the control panel is labeled “SET EXERCISE”

(see System Control Panel). The specific day and the

specific time of day this button is pressed is programmed

into the control board memory. This date and time is then

used to automatically initiate the system exercise cycle. The

“SET EXERCISE” legend on the control panel will flash until

the set exercise cycle is set.

To perform the Set Exercise procedure:

1. Choose the day and time you want your home

generator to exercise.

2. On that day and time, press and hold “SET EXERCISE”

for three seconds.

“SET EXERCISE” will flash until the button is pressed

for three seconds, then “SET EXERCISE” will illuminate

for 5 seconds, and finally turn off.

3. The unit will then start and run it’s 20 minute

exercise cycle.

For example, if you press SET EXERCISE on Sunday morning

at 10:00 AM, the unit will run an immediate exercise cycle

and an exercise cycle every following Sunday at 10:00 AM

(+/- 1/2 hour).

“Set Exercise” will only work if the unit is in the AUTO mode

and this exact procedure is followed. The exerciser will need

to be re-set if the 15 Amp fuse is removed or changed, or if

the starting battery is disconnected.

If you want to change the day and time the unit exercises,

simply perform the “Set Exercise” procedure at the exact

weekday and time you want it to take place.

Maintenance

Servicing the System

Before performing any generator maintenance, always

perform the following steps:

1. Set generator’s circuit breaker to its OFF position.

2. Set control panel system switch to OFF.

3. Remove 15 Amp fuse from control panel.

4. Utility voltage is present at generator control panel.

Disconnect power before servicing control panel by

removing the fuses from the transfer switch.

5. After all servicing has been completed, replace fuses in

transfer switch, replace 15 Amp fuse in control panel,

set system switch and circuit breaker ON and reset

exercise timer. See Setting Exercise Timer.

Fault Detection System

The generator may have to run for long periods of time

with no operator present. For that reason, the system is

equipped with sensors that automatically shut down the

generator in the event of potentially damaging conditions,

such as low oil pressure, high temperature, over speed, and

other conditions.

The generator’s control panel has a digital display that shows

fault codes, like “FC_1”. The table below lists the detected

fault, the fault code as displayed on the control panel, and

the number of LED flashes (also described as ‘blinks’) seen

on the remote LED indicator.

Fault Description Fault Codes LED Flashes

Low battery voltage FC_1 1

Low oil pressure FC_2 2

Low voltage FC_3 3

Engine fails to start FC_4 4

Low frequency FC_5 5

Engine overspeed FC_6 6

High temperature FC_7 7

Transfer switch fault FC_8 8

The remote LED indicator is installed at a convenient inside

location. The LED will remain lit when the generator is in

AUTO. Should a system fault be detected, the LED will turn

on and off in a series of blinks that identify the problem. The

blink pattern is repeated with a brief pause between each

series of blinks.

Reset Fault Detection System

The operator must reset the fault detection system each

time it activates. To do so, place the control panel system

switch in the OFF position for 30 seconds or more. Remedy

the fault condition, then return the generator to service by

installing the 15 Amp fuse, placing the system switch in the

AUTO position, and resetting the exercise timer. See Setting

Exercise Timer in Operation.

A description of each fault and suggested remedies are

as follows:

No LED ‑ Discharged Battery

If there is a detected fault condition but the LED is

not blinking, this is because the battery is completely

discharged. To remedy the problem, remove the 15 Amp

fuse and disconnect the battery from the generator. Take

the battery to a local battery store for analysis. Reinstall

battery after it has been fully recharged, connecting the

NEGATIVE cable last. Then reset the fault detection system,

as described earlier.

Low Battery Voltage (FC_1)

This fault is indicated by fault code FC_1 and one blink on

the LED indicator. This condition occurs if the generator

cannot start because the starting battery output power is

below that needed to crank the engine. Causes for this

problem may be a faulty battery or battery charge circuit.

To remedy the problem, contact your local service center to

check the battery charge output. Remove the 15 Amp fuse

and disconnect the battery from the generator. Take the

battery to a local battery store for analysis.

Reinstall the battery (replace if necessary - see Battery in

Final Installation Considerations in the installation manual).

Then reset the fault detection system, as described earlier.

Low Oil Pressure (FC_2)

This fault is indicated by fault code FC_2 and two blinks on

the remote LED indicator. The unit is equipped with an oil

pressure switch that uses normally closed contacts held

open by engine oil pressure during operation. Should oil

pressure drop below the 8 psi range, switch contacts close

and the engine is shut down.

To remedy the low oil pressure condition, add the

recommended oil to the FULL mark on the dipstick.

If the low oil pressure condition still exists, the engine will

start, then shut down again. The fault code will appear and

the LED will flash. In this case, contact an authorized dealer.

Low Voltage (Generator, FC_3)

This fault is indicated by fault code FC_3 and three blinks on

the LED indicator. This condition is caused by a restriction in

the fuel flow, a broken or disconnected signal lead, a failed

alternator winding, the control panel circuit breaker is open,

or the generator is overloaded.

To remedy the problem, contact your installer or an

authorized dealer.

Engine Fail To Start (FC_4)

This fault is indicated by fault code FC_4 and four blinks

on the LED indicator. This feature prevents the generator

from damaging itself if it continually attempts to start in

spite of another problem, such as no fuel supply. Each

time the system is directed to start, the unit will crank for

10 seconds, pause for 10 seconds, and repeat. If the system

does not begin producing electricity after approximately

2 minutes, the unit will stop cranking and the LED will blink.

Check to make sure the generator’s circuit breaker is in the

ON position in order for the sensing leads to verify that the

unit is running.

The most likely cause of this problem is no fuel supply.

Check the internal and external fuel shut off valves to

ensure they are fully open. Other causes could be failed

spark plug(s), failed engine ignition, or the engine air filter

is clogged. You may need to contact your installer for

assistance if you can’t remedy these problems.

Low Frequency (FC_5)

This fault is indicated by fault code FC_5 and five blinks on

the LED indicator. This feature protects devices connected

to the transfer switch by shutting the generator down if the

engine runs slower than 55 Hz for three seconds.

This condition is caused by a failed engine component or by

excessive loads on the generator. To remedy the problem,

contact your installer or an authorized dealer.

Engine Overspeed (FC_6)

This fault is indicated by fault code FC_6 and six blinks on

the LED indicator. This feature protects devices connected

to the transfer switch by shutting the generator down if

the engine happens to run faster than the preset limit. The

overspeed fault is detected as follows:

•Ifthegeneratoroutputfrequencyis65-70Hz,afterthree

seconds, the generator will shut down.

•Ifthegeneratoroutputfrequencyisgreaterthan70Hz,

the generator will shut down immediately.

This condition is caused by a failed engine component.

To remedy the problem, contact your installer or an

authorized dealer.

18 BRIGGSandSTRATTON.COM

High Temperature (FC_7)

This fault is indicated by fault code FC_7 and seven blinks

on the LED indicator. The contacts of the temperature

switch are normally open. If the engine temperature exceeds

approximately 115°C (240°F), the fault is detected and the

engine shuts down.

Common causes for this condition include running the

unit with all access doors removed, obstructed air inlet or

exhaust port, low oil or coolant level, or debris in the engine

compartment or radiator.

To resolve the problem, let the engine cool down and remove

any accumulated debris and obstructions. Ensure that all

access doors are installed whenever the unit is running.

Transfer Switch Fault (FC_8)

This fault is indicated by fault code FC_8 and eight blinks

on the LED indicator (if transfer switch is equipped with

fault detection).

The most likely cause of this fault is a blown fuse in the

transfer switch. To remedy the problem, contact your

installer or an authorized dealer.

Generator Maintenance

The generator warranty does not cover items that have been

subjected to operator abuse or neglect. To receive full value

from the warranty, the operator must maintain the system as

instructed in the engine operator’s manual.

All adjustments should be made at least once each season.

Follow the requirements in the engine operator’s manual.

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.

Engine Maintenance

An engine manual was packaged with this system. Refer to

that manual for all engine-related maintenance topics, such

as oil, oil filter, air cleaner, coolant, spark plugs and so forth.

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.
