Briggs & Stratton Power Products Home Generator System
Owners Manual
INTRODUCTION
Congratulations on your purchase of a Briggs & Stratton
Home Generator System (HGS).Your HGS was designed to
provide automatic auxiliary electrical power for the
duration of normal power interruption. It is not intended
for use as primary power in place of utility nor for use in
life-support applications.The generator unit has been
engineered and tested to exacting standards of
performance and reliability and is equipped with a UL®
listed Automatic Power Transfer Switch.
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 qualified 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 “Owners Manual”, a separate “Installation Manual”
(part number 190838) and a Warranty Sheet (part number
190881).These are important documents and should be
retained by the owner after the installation has been
completed.
Installation Assistance
For the Home or Business 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, or your utility power
provider.
The HGS Warranty is V
OID unless the system
is installed by certified 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 Owner’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.
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.
6
Briggs & Stratton Power Products Home Generator System
Owners Manual
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.
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%.
CAUTION!This equipment 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 backup 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.
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.
Generator Clearances
The generator enclosure must be a minimum of 3 ft.
(92 cm) from combustible material (NFPA 37). Leave at
least 3 ft. (92 cm) all around the enclosure for access to the
inside of the enclosure (NEC Art. 110-26a,Art. 110-26b).
The unit’s exhaust port must be at least 5 ft. (152 cm) from
any building opening (window, door, vent etc.), and the
exhaust must not be able to accumulate in any occupied
area (Figure 1).

installation details.Variations to this illustration are related
to code issues, piping distances and materials.
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. Because the Home Generator System is
equipped with an Automatic
Transfer Switch, your selection
of essential circuits will be transferred to the Home
Generator System within 15 seconds (+/- 5 seconds).
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 3 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 “Backup 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 does not give wattage,
multiply 120 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
emergency 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 for a maximum of 500 hours of
operation per year. The standby rating is only applicable
for emergency and 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.

•“AUTO” position is the normal operating position. If a
utility power outage is sensed, the system will start the
generator, let it reach stable operating speed, then
connect generator power to the transfer switch.When
utility power is restored, the system reconnects utility
power to the transfer switch, lets the engine stabilize
internal temperatures, shuts off the generator, and waits
for the next utility power outage.While waiting, it
maintains battery with trickle charge.
•“OFF” position turns off running generator, takes system
out of Automatic mode and resets any detected faults.
•“MANUAL” position starts the engine but does not
disconnect the transfer switch from utility power. It is
used for maintenance or diagnostic functions.

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 owner’s manual.
CAUTION! Any attempt to crank or start the
engine before it has been properly serviced with the
recommended oil will result in an engine failure that
is not covered under warranty.
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.
In order to provide a greater “backup” capability, 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
owner’s manual.
Battery Connection
The Home Generator System is supplied with a 12 Volt DC
18 Amp-Hour sealed rechargeable battery. It is installed in
the unit and the battery cables are connected at the
factory.The unit’s 15 Amp fuse has been removed for
shipping (this prevents the unit from starting).
CAUTION! DO NOT install the 15 Amp fuse
until all plumbing and wiring has been completed
and inspected. Failure to install the fuse as described
in the Installation Manual could cause the engine to
start.
NOTE:With the battery installed, 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 pipe connections are tight, secure and
without leaks.
• Ensure that all shutoff valves are OPEN and that
adequate pressure is available.
If you smell ‘raw’ gaseous fuel (natural or LP) near the unit,
immediately turn off the gas supply to the generator.
Contact your gas utility or the system installer for
assistance in determining the source of the smell.
The AUTO/OFF/MANUAL Switch
This three-position device is referred to herein as
“AUTO/OFF/MANUAL”. It is found on the control panel, as
shown earlier, and is used as follows:
•“AUTO” position is the normal operating position. If a
utility power outage is sensed, the system will start the
generator, let it reach stable operating speed, then
connect generator power to the transfer switch.
When utility power is restored, the system reconnects
utility power to the transfer switch, lets the engine ‘cool
down’, shuts off the generator, and waits for the next
utility power outage.
•“OFF” position turns off a running generator, takes the
system out of Automatic mode and resets faults.The unit
will not exercise, but the ‘Set Exercise’ setting is not lost.
•“MANUAL” position starts the engine but does not
disconnect utility power from the transfer switch. It is
used for maintenance or diagnostic functions.
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 AUTO/OFF/MANUAL switch
to OFF and remove the 15 Amp fuse before
working on or around the generator or transfer
switch.
The other controls and devices installed on the control
panel are described on page 11,“Know Your System
Control Panel”.

AUTOMATIC OPERATION
To select automatic transfer operation, do the following:
1. Set the main distribution panel circuit breaker that
sends utility voltage to the transfer switch to ON.
2. Set the AUTO/OFF/MANUAL switch to AUTO.
3. Set the generator’s main circuit breaker to its ON
position.
Checking Automatic Operation
To check the system for proper automatic operation,
proceed as follows:
1. Check that AUTO/OFF/MANUAL is set to OFF.
2. Apply utility power to the Automatic Transfer Switch
by turning ON the main distribution panel circuit
breaker.
3. Set the AUTO/OFF/MANUAL switch to AUTO.The
Automatic Power System is now ready for automatic
operation.
4. Turn OFF the main distribution panel circuit breaker
sending power to the automatic transfer switch.
The engine will crank and start once the utility voltage
drops out and the sensor has timed out.After starting, the
Automatic Power Transfer System will transfer essential
circuit loads to the generator. Let the system go through its
entire automatic operation sequence.
5. With the generator output supplying its loads, turn
ON the main distribution panel circuit breaker that
supplies utility power to the Automatic Power Transfer
Switch.
6. After about 6 seconds, the automatic transfer switch
will transfer loads back to the utility power.
7. About one minute after re-transfer, the engine will shut
down.
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.
Stopping the System
To disable the power transfer system for maintenance:
1. Ensure that the main distribution panel circuit breaker
that sends utility voltage to the transfer switch is ON.
2. Set the AUTO/OFF/MANUAL switch to OFF.
3. Set the generator’s main circuit breaker to its OFF
position.
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 12 minutes and then shuts down. Electrical
load transfer DOES NOT occur during the exercise cycle
(unless an utility power outage occurs).
15
Briggs & Stratton Power Products Home Generator System
Owners Manual
A switch on the control panel is labeled “Set Exercise”
(depicted on 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.
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, set the AUTO/OFF/MANUAL
switch to OFF.
3. Press and hold down the “Set Exercise” switch until
the Diagnostic LED turns on (about five seconds).
4. Hold the switch down until the Diagnostic LED turns
off. Release the Set Exercise switch.
5. Set the AUTO/OFF/MANUAL switch to AUTO.“Set
Exercise” is complete.
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.
NOTE:“Set Exercise” will only work if the unit is in the
Automatic mode and this exact procedure is followed.The
exerciser does not need to be re-set if the 15 Amp fuse is
removed or changed.The exerciser will need to be re-set 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.

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.
A light on the generator's control panel is called the
Diagnostic LED.A similar LED indicator is installed at a
convenient inside location. Both LED's will turn on and off
in the same series of blinks if certain problems are
detected in your HGS.The blink pattern is repeated with a
brief pause between each series.The number of blinks in
the series indicates the detected fault, as listed near the
control panel, on the mounting plate and below:
Number of LED Flashes Fault Description
1 Low battery voltage 2 Low oil pressure 3 Low voltage 4 Engine fail to start 5 Low frequency 6 Engine overspeed 7 Oil temperature high
Reset Fault Detection System
The operator must reset the fault detection system each
time it activates.To do so, place the AUTO/OFF/MANUAL
switch in the OFF position for 30 seconds or more.
Return the Home Generator System to service after
correcting the problem by placing the
AUTO/OFF/MANUAL switch in the AUTO position.
A description of each fault and suggested remedies are as
follows:
No Blinks - ‘Dead’ Unit
This condition is caused by a completely dead starting
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 in the battery compartment after it has
been fully recharged, connecting the NEGATIVE cable last.
Install the 15 Amp fuse. Reset the Fault Detection system
as described above.
Low Battery Voltage
This fault is indicated by one blink.This condition occurs if
the generator cannot start because the starting battery
output power is below that needed to ‘turn-over’ the
engine. Causes for this problem may be a failed battery or a
failed trickle charger circuit.
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 in the battery compartment after it has
been fully recharged, connecting the NEGATIVE cable last.
Install the 15 Amp fuse. Reset the Fault Detection system
as described above. Check battery trickle charge output.
Low Oil Pressure
This fault is indicated by two blinks.The unit is equipped
with an oil pressure switch (Figure 5) 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, fix any obvious
oil leak and/or add the recommended oil to the FULL mark
on the dipstick. Reset the Fault Detection system as
described above.
If low oil pressure condition still exists, engine will start,
then shut down after about 10 seconds and diagnostic LED
will flash. In this case, contact an authorized service facility.

Briggs & Stratton Power Products Home Generator System
Owners Manual
Low Voltage
This fault is indicated by three blinks.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 overloaded circuits
in the transfer switch.
Remedy the problem (you may need to contact your
installer or Briggs and Stratton Technical Services for
assistance), then reset the Fault Detection system, as
described above.
Engine Fail To Start
This fault is indicated by four blinks.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 15 seconds, pause for 15 seconds, crank for
15 seconds, pause for 15 seconds, and repeat. If the system
does not begin producing electricity after approximately
90 seconds, the unit will stop cranking and the LED will
blink.
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.When the
problem is corrected, reset the Fault Detection system as
described above.
Low Frequency
This fault is indicated by 5 blinks.This feature protects
devices connected to the transfer switch by shutting the
generator down if its engine runs slower than the preset
limit.
This condition is caused by a failed engine governor or by
excessive loads on the transfer switch.To remedy the
problem, you may need to contact your installer or Briggs
and Stratton Technical Services for assistance.When the
problem is corrected, reset the Fault Detection system as
described above.
Engine Overspeed
This fault is indicated by 6 blinks.This feature protects
devices connected to the transfer switch by shutting the
generator down if its engine happens to run faster than the
preset limit.The overspeed fault is detected as follows:
• If the generator output frequency runs at 72 Hz for five
seconds, the generator will shut down.
• If the generator output frequency reaches 75 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
Briggs and Stratton Technical Services for assistance.When
the problem is corrected, reset the Fault Detection system
as described above.
Oil Temperature High
This fault is indicated by seven blinks.The contacts of the
temperature switch (Figure 5) are normally open. If the
engine 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, 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.When the problem is
corrected, reset the Fault Detection system as described
above.
Power During Fault Condition
Whenever the Home Generator System is in an
uncorrected fault condition, the automatic transfer switch
is reset to UTILITY POWER.This means that when utility
power is restored, utility power will be applied to the
essential circuit loads.The generator is disconnected from
the automatic transfer switch for the duration of any
detected fault condition.

GENERATOR
MAINTENANCE
The generator warranty does not cover items that have
been subjected to operator abuse or negligence.To receive
full value from the warranty, the operator must maintain
the system as instructed in the engine owner’s manual.
All adjustments should be made at least once each season.
Follow the requirements in the engine owner’s manual.
Generator maintenance consists of keeping the unit clean
and dry. 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.
Check the cleanliness of the unit frequently and clean when
dust, dirt, oil, moisture or other foreign substances are
visible on its exterior surface.
NOTE:Do Not use direct spray from a garden hose to
clean generator.Water can enter the engine and cause
problems. In addition, if water enters the generator through
cooling air slots, some water will be retained in voids and
cracks may develop in the rotor and stator winding
insulation.Water and dirt buildup on the generator internal
windings will eventually decrease the insulation resistance
of these windings.
Changing Engine Oil
• Place the oil drain tube into an approved container.
• Push in and rotate the oil drain fitting 1/4 turn
counterclockwise. Slowly pull outward until oil starts
draining (Figure 6). DO NOT pull the oil drain fitting off
the engine.
• When the oil has drained, push the oil drain fitting in
and rotate 1/4 turn clockwise until it locks in place.
• Slide the oil drain tube up into the clamp on the
generator.
CAUTION!Any attempt to crank or start the engine
before it has been properly filled with the recommended oil
will result in engine failure.
To fill your engine with oil:
• Follow the synthetic oil grade recommendation and oil
fill instructions given in the engine owner’s manual.
To Clean the Generator
CAUTION! NEVER insert any object or tool
through the air cooling slots, even if the engine is
not running.
• Use a damp cloth to wipe exterior surfaces clean.
• A soft, bristle brush may be used to loosen caked on
dirt, oil, etc.
• A vacuum cleaner may be used to pick up loose dirt and
debris.
• Low pressure air (not to exceed 25 psi) may be used to
blow away dirt. Inspect cooling air slots and openings on
the generator.These openings must be kept clean and
unobstructed.
