INTRODUCTION
Thank you for your purchase of a Briggs & Stratton
Home Generator System (HGS).This product is intended
for use as an optional home standby system which provides
an alternate source of electric power and to serve loads
such as heating, refrigeration systems, and communication
systems that, when stopped during any power outage, could
cause discomfort, or the like.This product does not qualify
for emergency standby as defined by NFPA 70 (NEC).
Briggs and Stratton has 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 contractors should attempt
HGS installations.
Installations must strictly comply with
all applicable codes, industry standards
and regulations.
Your Briggs & Stratton Home Generator System 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.
Installation Assistance
For the Home Owner:
To help you make informed choices and communicate
effectively with your installation contractor(s),
Read and understand the
Owner Orientation Section of this manual
BEFORE
contracting or starting
your HGS installation.
To arrange for proper installation, contact the store at
which you purchased your Briggs & Stratton Home
Generator System, your dealer, a licensed electrician or
your utility power provider.
The HGS Warranty is V
OID unless the system
is installed by licensed electrical and
plumbing professionals.
For the Installing Dealer/Contractor:
For most applications, the Installation manual contains all
the information required to properly install and start the
Home Generator System.This Operator’s Manual
describes essential circuit selection, routine operation and
owner maintenance procedures.
If you need more information, call 1-800-743-4115,
between 8:00 AM and 5:00 PM CT.
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).
OWNER ORIENTATION
This section provides Home Generator System 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 System.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, equal compensations in piping
and wiring materials must be allowed for.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
System installation.
NOTE: In some areas you may need to acquire electrical
permits for installing the Home Generator System, 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.
INSTALLATION
6
Fuel Factors
An important consideration affecting the entire installation
is the type of fuel used by your Home Generator System.
The system was factory tested and adjusted using natural
gas as a fuel. Liquid propane (LP) may also be used as a fuel
(see the Installation Manual).
Although there are specific factors that are inherent to each
of these fuels, your location and the duration of possible
utility interruptions should guide your selection of fuel type.
For urban installations, Natural Gas (if available) should be
your fuel of choice. For remote installations, a Liquefied
Petroleum (LP) tank might better meet your needs.
For proper engine function, the following fuel guidelines are
recommended:
• 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) gas,
commercial grade HD5 propane with a minimum fuel
energy of 2500 BTUs/ft3with maximum propylene
content of 5% and butane and heavier gas content of
2.5% and minimum propane content of 90%.
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 HGS 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.
NOTE: 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.
Home Generator System Location
Before installing generator, consult with homeowner and
convey the following guidelines which may affect the
desired location.
Generator Clearances
Place generator in a well ventilated area which will allow
for removal of deadly exhaust gas. 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 (Figure 1). Prevailing winds
and air currents should be taken into consideration when
positioning generator.
General Location Guidelines
• Install the unit outdoors ONLY.
• Place the unit in a prepared location that is flat and has
provisions for water drainage.
• Install the unit 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 our outlet openings.
• Install the unit where the location of any services such as
phone, electrical, fuel, air conditioning, irrigation, including
covered, concealed and underground services will not be
affected or obstructed.
• The Home Generator System 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.
Propane and Natural Gas is extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.
WARNING
• Operate generator ONLY outdoors.
• Keep exhaust gas from entering a confined area through
windows, doors, ventilation intakes or other openings.
Running generator gives off carbon monoxide,
an odorless, colorless, poison gas.
Breathing carbon monoxide can cause nausea,
fainting or death.
WARNING
• Keep at least 5 ft. (152 cm) clearance on all sides of generator
including overhead.
Exhaust heat/gases can ignite combustibles or
structures causing a fire.
WARNING
INSTALLATION

• 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, you may
need to construct a windbreak to protect the unit.
• Install the generator as close as possible to the Transfer
Switch to reduce the length of wiring and conduit.
• Install the generator as close as possible to the fuel
supply to reduce length of pipes.
IMPORTANT: Laws or local codes may regulate the
distance to the fuel supply.
The Home Generator System is shipped already attached
to its mounting pad. Unless mandated by local code, a
concrete slab is not required.
If mandated by local code, construct a concrete slab at least
3 inches thick and 6 inches longer and wider than the unit.
Attach unit to slab with 1/4” diameter (minimum) masonry
anchor bolts long enough to retain the unit.
Essential Circuits
As a Home Generator System owner, it is important that
you clearly identify the circuits in your building that are
"essential" to you.
It is important that your installer understand 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 System for the
duration of normal power interruption.
The wattage reference guide shown in Figure 2 will assist
you with your decision-making process.It provides the
wattage used by many ordinary household devices. Use it as
a guide when selecting your essential circuits. Review this
information with your installer and ask about any technical
considerations that might affect the cost of your installation.

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 decal 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 System:
• Figure the watts required to start the largest motor.
• Add that to the total running watts of all other
connected loads.
This Briggs & Stratton Home Generator System
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 Guide” 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.
IMPORTANT:When using the 100 Amp or 200 Amp
transfer switch with the Home Generator System, you must
turn off any non essential loads. Failure to turn off non
essential loads could overload the generator causing it to shut
down. Some examples of non essential loads are as follows:
• Pool pump
• Hot tub
• Electric hot tub and/or pool heaters
• Central air conditioners
• Electric hot water heaters
• Electric range and/or oven
• Arc welder
• Non essential electric heaters
UNPACKING
Refer to the Installation Manual for detailed unpacking
instructions, if desired.
Delivery Inspection
After removing the carton, carefully inspect the Home
Generator System for any damage that may have occurred

BEFORE INITIAL START-UP
Engine Oil
This engine is shipped from the factory filled with the
recommended oil. Before starting the engine, check oil level
and ensure that engine is serviced as described in the
engine operator’s manual.
Oil Considerations
Your Home Generator System is equipped with an engine
that has been pre-run at the factory and does not require
the traditional “break-in” procedure.
The system is filled with synthetic oil (API SJ/CF 5W-30W).
This allows for system operation in the widest range of
temperature and climate conditions.
NOTE:The use of synthetic oil DOES NOT alter the
required oil change intervals described in the engine
operator’s manual.
Battery Connection
The Home Generator System is supplied with a 12 Volt DC
55 Amp-Hour, valve regulated battery. It is a sealed, lead-acid
rechargeable battery. It is installed in the unit and the
battery cables are connected at the factory.The generator’s
15 Amp fuse has been removed to prevent the unit from
starting during shipping.
NOTE:With the battery installed, all wiring to transfer
switch and Home Generator System 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 charger cannot
be used to recharge a battery that is completely discharged.
Gaseous Fuel System
• Ensure that all fuel connections are tight, secure and
without leaks.
• Ensure that all shutoff valves are OPEN and that
adequate pressure is available (see installation manual).
CAUTION
• Refer to engine manual for oil fill information.
• Damage to equipment resulting from failure to follow this
instruction will void warranty.
Any attempt to crank or start the engine before it has
been properly serviced with the recommended oil will
result in equipment failure.
• DO NOT install the 15 Amp fuse until all plumbing and wiring
has been completed and inspected.
Installing the 15A fuse could cause the engine to start.
CAUTION
• DO NOT operate engine if smell of fuel is present or other
explosive conditions exist.
• If you smell ‘raw’ gaseous fuel (natural or LP) near the unit,
immediately turn off the gas supply to the Home Generator
System.
• Contact your gas utility or the system installer for assistance
in determining the source of the smell.
Propane and Natural Gas is extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.

AUTOMATIC OPERATION
To select automatic operation, do the following:
1. Set the service disconnect or main distribution panel
circuit breaker that sends utility voltage to the transfer
switch to ON.
2. Set the generator’s main circuit breaker to its ON
position.
3. Set the 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.
The engine will crank and start when the utility voltage
drops out and the sensor has timed out. 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 the utility power after 5 minute minimum run time
and utility is restored.
4. The generator will run for an additional one minute for
engine cool down, then shut down.
NOTE: If utility 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 System will now start
automatically when utility power is lost and will supply
power to the transfer switch.
Servicing the System
To service system:
1. Set the system switch to OFF.
2. Set the generator’s main circuit breaker to its OFF
position.
3. Utility voltage is present. Disconnect power before
servicing by removing the two 2 Amp fuses from the
transfer switch.
Setting Exercise Timer
The Home Generator System 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 switch on the control panel is labeled “Set Exercise” (see
page 10).The specific day and the specific time of day this
switch is pressed is programmed into the control board
memory.This date and time is then used to automatically
initiate the system exercise cycle.The LED on the control
panel will flash until the set exercise is set.
To perform the Set Exercise procedure:
1. Choose the day and time you want your Home
Generator System to exercise.
2. On that da
y and time, press and hold down the “Set
Exercise” switch for three seconds.
NOTE:The LED will flash until the switch is pressed for
three seconds, then the LED will illuminate for 5 seconds
and turn off.
For example, if you press the “Set Exercise” switch on
Sunday morning at 10:00 AM, the unit will run an exercise
cycle the following Sunday at 10:00 AM (+/- 1/2 hour).
NOTE:“Set Exercise” will only work if the unit is in the
Automatic 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 12 Volt DC 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.
• To prevent possible injury that might be caused by such sudden
starts, always set the system switch to OFF.
• Remove the 15 Amp fuse before working on or around the
generator or transfer switch.
With the switch set to AUTO, the engine may crank
and start at any time without warning. Such automatic
starting normally occurs when utility source voltage
drops below a preset level or during the normal
exercise cycle.

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 oil temperature, over speed,
and other conditions.
The generator's control panel has a digital display to show
fault codes.An extra LED indicator is installed at a
convenient inside location.The LED will turn on and off in a
series of blinks if certain problems are detected in your
HGS.The blink pattern is repeated with a brief pause
between each series.The fault code as shown on the
control panel, and the number of blinks on the mounting
plate, indicates the detected fault and as follows:
Fault Codes / LED Flashes Fault Description
FC_1 / 1 Low battery voltage
FC_2 / 2 Low oil pressure
FC_3 / 3 Low voltage
FC_4 / 4 Engine fail to start
FC_5 / 5 Low frequency
FC_6 / 6 Engine overspeed
FC_7 / 7 Oil temperature high
FC_8 / 8 Transfer switch fault
Reset Fault Detection System
The operator must reset the fault detection system each
time it activates.To do so, place the system switch in the
OFF position for 5 seconds or more. Return the Home
Generator System to service after correcting the problem
by placing the system switch in the AUTO position.
A description of each fault and suggested remedies are as
follows:
No LED - Discharged Battery
This condition is caused by a completely discharged
battery.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.
Replace the battery after it has been fully recharged,
connecting the NEGATIVE cable last. Install the 15 Amp
fuse.
Low Battery Voltage
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 trickle charger circuit.
To remedy the problem, contact your local service center
to check the battery trickle charge output. Remove the
15 Amp fuse and disconnect the battery from the generator.
Take the battery to a local battery store for analysis.
Replace the battery after it has been fully recharged,
connecting the NEGATIVE cable last. Install the 15 Amp fuse.
Low Oil Pressure
This fault is indicated by fault code FC_2 and two blinks on
the LED indicator.The unit is equipped with an oil pressure
switch (Figure 4) using normally closed contacts that are
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 low oil pressure condition still exists, engine will start,
then shut down after about 20 seconds and diagnostic LED
will flash. In this case, contact an authorized service facility.

Low Voltage (Generator)
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 Home Generator System is overloaded.
To remedy the problem, contact your local service center.
Engine Fail To Start
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, 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 main circuit breaker is
in the ON (closed) 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 inside and outside 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
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 the preset limit.
• If the generator output frequency is below 55 Hz for
three seconds, the generator will shut down.
This condition is caused by a failed engine governor or by
excessive loads on the generator. To remedy the problem,
you may need to contact your installer or local service
center for assistance.
Engine Overspeed
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 instantly.
This condition is caused by a failed engine governor.To
remedy the problem, you should contact your installer or
local service center for assistance.
Oil Temperature High
This fault is indicated by fault code FC_7 and seven blinks
on the LED indicator.The contacts of the temperature
switch (Figure 4) are normally open. If the engine oil
temperature exceeds approximately 140°C (284°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 level, or debris in the engine cylinder
cooling fins.
To resolve the problem, remove any accumulated debris
and obstructions and let the engine cool down. Ensure that
the Oil Service door and/or the Control Panel door is
installed whenever the unit is running.
Transfer Switch Fault
This fault is indicated by fault code FC_8 and eight blinks
on the LED indicator (if transfer switch is equipped with
fault detection).
To remedy the problem, you should contact your installer
or local service center for assistance.
