SAVETHESE INSTRUCTIONS
This manual contains important instructions that should be
followed during installation and maintenance of the generator
and battery.
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 VOID 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
7
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/ft
3
with 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
Install generator outdoors in an area which will not accumulate
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.
WARNING
Propane and Natural Gas are extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.
• 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.
Figure 1 — Home Generator System Location
Exhaust Port
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.
• Keep at least 3 ft. (91 cm) clearance on all sides of generator
including overhead.
INSTALLATION

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.
• 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

INSTALLATION
13
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).
NOTICE
Any attempt to crank or start the engine before it has been
properly serviced with the recommended oil will result in
equipment failure.
• Refer to engine manual for oil fill information.
• Damage to equipment resulting from failure to follow this
instruction will void warranty.
CAUTION
Installing the 15A fuse could cause the engine to
start.
• DO NOT install this fuse until all plumbing and wiring has been
completed and inspected.
WARNING
Propane and Natural Gas are extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.
• 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.
OPERATION
14
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 11). 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 day 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.
CAUTION
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.
• 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.
MAINTENANCE

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.
