OWNER ORIENTATION
This section provides the Standby Generator owner 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 the Standby Generator. A thorough
understanding of these options will provide fundamental
control over the cost of installation, as well as ensure 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.As the distance
from the existing electrical service and gaseous fuel supply
increases, so must the piping and wiring materials.This is
necessary to comply with local codes, overcome electrical
voltage drops and gaseous fuel pressure drops.
The factors mentioned above will have a direct
affect on the overall price of your Standby
Generator installation.
NOTE: In some areas you may need to acquire electrical
permits for installing the Standby 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 generator.
Fuel Factors
An important consideration affecting the entire installation
is the type of fuel used by your Standby Generator.The
generator was factory tested and adjusted using natural gas
as a fuel. Liquid propane (LP) may also be used as fuel by
installing the included conversion kit.
For proper generator performance, the following fuel
guidelines are recommended:
In engines set up to run on propane (LP) gas, 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%.
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.
INSTALLATION
PROCEDURES
Unpacking Precautions
The unit is shipped bolted to its mounting pad, ready for
installation.Avoid damage from dropping, bumping, collision,
etc. Store and unpack carton with the proper side up, as
noted on the shipping carton.
Delivery Inspection
After removing the carton, carefully inspect the Standby
Generator for any damage that may have occurred during
shipment.
IMPORTANT: If loss or damage is noted at time of
delivery, have the person(s) making delivery note all damage
on the freight bill and affix his signature under the
consignor's memo of loss or damage. If loss or damage is
noted after delivery, separate the damaged materials and
contact the carrier for claim procedures.Missing or
damaged parts are not warranted.
Approved Transfer Switches
The Standby Generator should be used ONLY with Briggs
& Stratton Power Products UL approved Transfer Switches.
Connection to any other transfer switch will void your
generator warranty.
• The Home Standby 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.
Propane and Natural Gas are extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.

Standby Generator Location
Before installing generator, consult with homeowner and
convey the following guidelines which may affect the
desired location.
Generator Clearances
The generator enclosure must be a minimum of 3 ft. (92 cm)
from combustible material. Leave at least 3 ft. (92 cm) all
around the enclosure for access to the inside of the enclosure.
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).
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 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 Standby Generator 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
Consult with owner to clearly identify the circuits in
building that are "essential".
It is important that you understand which circuits the
owner wants to include as "Essential Circuits". Depending
on the power consumed by these circuits,most or all of
them can be switched to the Standby Generator for the
duration of normal power interruption.

Briggs & Stratton Power Products Standby Generator
Installation, Start-Up and Owner’s Manual
The wattage reference guide shown in Figure 2 will assist
the owner with their decision-making process. It provides
the wattage used by many ordinary household devices. Use
it as a guide when selecting essential circuits. Review this
information with the owner and convey any technical
considerations that might affect the cost of 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 does not give 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 Standby
Generator:
• Figure the watts required to start the largest motor.
• Add that to the total running watts of all other
connected loads.
This Briggs & Stratton Standby 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 Guide” provided and mark
those circuits you consider “critical” or “essential”. Make
sure you and your installer consider the generator’s
altitude above sea level and the ambient temperature range
when determining total generator load.

THE GASEOUS FUEL
SYSTEM
Consult with the Standby Generator owner(s) and convey
any technical considerations that might affect their
installation plans before applying these general guidelines.
The following general rules apply to gaseous fuel system
piping:
• The piping should be of a material that conforms to
federal and local codes, rigidly mounted and protected
against vibration.
• Install flexible gaseous pipe (supplied) between the
standby generator fuel inlet port and rigid piping.
• Piping must be of the correct size to maintain the
required supply pressures and volume flow under varying
conditions.
• Use an approved pipe sealant or joint compound on all
threaded fittings to reduce the possibility of leakage.
• Installed piping must be properly purged and leak tested,
in accordance with applicable codes and standards.
Consider the following factors when planning to
install the fuel supply system:
The Standby Generator engine is fitted with a fuel mixer
system that meets the specifications of the California Air
Resources Board for “tamper-proof” dual fuel systems.The
unit will run on natural gas or liquefied propane.
• A minimum of one manual shutoff valve should be placed
in the fuel supply line and located outside the building to
facilitate servicing the generator.
• Natural gas fuel supply pressure at the generator's fuel
inlet port should be between 5 to 7 inches of water (in.
W.C.) at full load. LP fuel supply pressure should be 11 to
14 inches of water (in.W.C.) at full load.
The Standby Generator unit has been factory set to
run on natural gas. If you need to change from natural
gas to LP gas, the unit will need to be reconfigured, as
described on page 17.
It is recommended that the fuel connection incorporate
the following components:
• A manual fuel shut-off valve located in the interior of the
building.
• A manual fuel shut-off valve located outside the building,
just before the generator unit.
• The termination of hard piping should include a sediment
trap.
• A manometer port should be provided.
• The entire flexible gaseous pipe must be visible for periodic
inspection and must not be concealed within, contact, or run
through any wall, floor, or partition.
The supplied flexible gaseous pipe is not to be installed
underground or in contact with the ground.
CAUTION
The information provided below is to assist
gaseous fuel system technicians in planning
installations. In no way should this information
be interpreted to conflict with applicable fuel gas
codes. Consult with your local fuel supplier or
Fire Marshall if questions or problems arise.
• LP gas is heavier than air and will settle in low areas.
• Natural gas is lighter than air and will collect in high areas.
• The slightest spark can ignite these fuels and cause an explosion.
Propane and Natural Gas are extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.
WARNING
The manometer port permits temporary installation of a
manometer (Figure 5), to ensure that the engine receives
the correct fuel pressure to operate efficiently throughout
its operating range.
NOTE:A digital manometer, P/N 19495, is available at your
local Briggs and Stratton Power Products service center.
When the initial test runs are completed, the manometer is
removed and the port is plugged.A typical final fuel
connection assembly is shown in Figure 6.
Fuel Consumption
See Figure 7 for fuel supply requirements at half and full
load for both natural gas and LP vapor.
13
Briggs & Stratton Power Products Standby Generator

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.
Oil Considerations
Your Standby Generator is equipped with an engine that
has been pre-run at the factory and does not require the
traditional “break-in” procedure.
The generator is filled with synthetic oil (API SJ/CF 5W30W).This allows for generator 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 Standby Generator is supplied with a 12 Volt DC
33 Amp-Hour 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 battery from discharging and
the unit from starting during shipping.
If it is necessary to service the battery, proceed as follows:
1. Set generator's “AUTO/OFF/MANUAL” switch to
OFF.
2. Pull service disconnect from disconnect box.
3. Remove 15 Amp fuse from control panel.
4. Service or replace battery as required.
5. Connect red battery cable to positive battery terminal
(indicated by POSITIVE, POS, or (+).
6. Connect black battery cable to negative battery
terminal (indicated by NEGATIVE, NEG, or (-).
7. Ensure hardware on both positive and negative battery
terminals is secure.
8. Reinstall 15 Amp fuse in control panel.
9. Reinstall service disconnect in disconnect box.
10. Set generator's “AUTO/OFF/MANUAL” switch to
AUTO.
11. Reset exercise timer following instructions “Setting
Exercise Timer” on page 19.
NOTE:With the battery installed and utility power
available to the Transfer Switch, the battery receives a
trickle charge whenever the engine is not running.The
trickle charge only prevents self-discharge and cannot be
used to recharge a battery that is completely discharged.
Fuel Supply System
Ensure that all fuel pipe connections are tight, secure and
without leaks.
Ensure that all gas line shutoff valves are OPEN and that
adequate fuel pressure is available whenever automatic
operation is desired.
FUEL SYSTEM SELECTION
The engine of your Standby Generator is factory calibrated
to run on natural gas (NG). It may also be operated on
liquid propane (LP).
To configure the fuel system for LP use:
1. LP fuel inlet pressure must be between 11 and
14 inches water column.
2. Set AUTO/OFF/MANUAL switch to OFF.
3. Pull service disconnect from disconnect box.
4. Remove 15 Amp fuse.
5. Change main jet in fuel mixer following instruction
sheet provided in LP conversion kit.
NOTE:You will need a specialty tool, as described on
page 9, to change the main jet.
6. Reinstall 15 Amp fuse.
7. Reinstall service disconnect in disconnect box.
• 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
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.

Installation, Start-Up and Owner’s Manual
8. Set AUTO/OFF/MANUAL switch to AUTO.
9. Reset exercise timer following instructions “Setting
Exercise Timer” on page 19.
The generator is now ready to operate automatically using
LP fuel.With a fixed main jet for LP gas, there is no need to
perform any engine adjustments for LP operation.
INITIAL START-UP (NO LOAD)
Begin testing the generator without any electrical loads
connected, as follows:
1. Set AUTO/OFF/MANUAL switch to OFF.
2. Set generator’s main circuit breaker to OFF (open)
position.
3. Install 15 Amp fuse in control panel.
4. Set AUTO/OFF/MANUAL switch to MANUAL.
NOTE:When the Standby Generator is started for the
very first time, it will require that air in the gaseous fuel
lines be purged.This may take a few minutes.
5. DO NOT crank engine for more than 15 seconds per
minute to reduce heat in starter.
6. Repeat process until engine starts.
7. Listen for unusual noises, vibration or other indications
of abnormal operation. Check for oil leaks while the
engine runs.
8. Let engine warm up for about five minutes to allow
internal temperatures to stabilize.Then, set generators
main circuit breaker to ON (or closed) position.
9. Connect an accurate AC voltmeter and a frequency
meter to check generator output at load side of circuit
breaker.Voltage should be 230-240 Volts, frequency
should be 62.0 - 62.5 Hz.
10. Check generator output between one
emergency/generator connection lug and neutral lug,
then between other emergency/generator connection
lug and neutral lug. In both cases, voltage reading
should be between 115-120Volts.
11. Set AUTO/OFF/MANUAL switch to OFF. Engine will
shut down.
AUTOMATIC OPERATION
SEQUENCE
The generator’s control panel houses a logic control circuit
board.This control board constantly monitors utility power
source voltage. Should that voltage drop below a preset
level, control board action will signal the engine to crank
and start.
When utility source voltage is restored above a preset
voltage level, the engine is signaled to shut down.
The actual system operation is not adjustable and is
sequenced by sensors and timers on the control board, as
follows:
Utility Voltage Dropout Sensor
• This sensor monitors utility source voltage.
• If utility source voltage drops below 70 percent of the
nominal supply voltage, the sensor energizes a six second
timer.
• Once the timer has expired, the generator will start.
Utility Voltage Pickup Sensor
This sensor monitors utility power supply voltage.When
that voltage is restored above 70 percent of the nominal
source voltage, a time delay starts timing and the generator
will go to engine cool-down.
Engine Cool-down Timer
• When the load is transferred back to the utility power
source, the engine cool-down timer starts timing.
• The timer will run for about one minute, then the
generator will stop.
• Minimum generator run time is five minutes.
19
Briggs & Stratton Power Products Standby Generator
Installation, Start-Up and Owner’s Manual
SETTING EXERCISE TIMER
The Standby Generator is equipped with an exercise timer
that will start and exercise the generator 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 7). On the specific day and time the switch is pressed,
the control board is programmed.This date and time is
then used to automatically initiate the generator exercise
cycle.
To perform the Set Exercise procedure:
1. Choose day and time you want Standby Generator to
exercise.
2. On that da
y and time, set AUTO/OFF/MANUAL switch
to OFF position.
3. Press and hold down “Set Exercise” switch for two
seconds.
4. Set 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 (+/- 1 hour).
NOTE:“Set Exercise” will only work if the unit is in the
Automatic mode and this exact procedure is followed.
If you want to change the day and time the unit exercises,
simply perform the “Set Exercise” procedure at the day and
time you want it to take place.
INSTALLATION
INSPECTION
Before placing the Standby Generator into service, inspect
the entire installation carefully. Ensure that any scratches or
broken paint on the inside or outside of the enclosure are

free of generator enclosure.
4. Set AUTO/OFF/MANUAL switch to OFF.
5. Set generator’s main circuit breaker to OFF position.
6. Pull service disconnect from disconnect box.
7. Remove 15A fuse from control panel.
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, over speed, and other conditions.
A light on the remote LED plate is called the Diagnostic
LED.The LED will turn on and off in a series of blinks if
certain problems are detected in your Standby Generator.
The blink pattern is repeated with a brief pause between
21
Briggs & Stratton Power Products Standby Generator
Installation, Start-Up and Owner’s Manual
each series.The number of blinks in the series indicates the
detected fault, as listed on the mounting plate and as
follows:
Number of LED Flashes Fault Description
2 Low oil pressure
4 Engine failed to start
5 Low frequency
6 Engine overspeed
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 Standby Generator 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 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 Oil Pressure
This fault is indicated by two blinks.The generator is
equipped with an oil pressure switch (Figure 11). Should oil
pressure drop, 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, generator will start,
then shut down after approximately 10 seconds and
diagnostic LED will flash. In this case, contact your local
service center.
Engine Fail To Start
This fault is indicated by four blinks.This feature prevents
the generator from damage by continually attempting to
start. Each time the system is directed to start, the
generator will crank for 15 seconds, pause for 15 seconds,
crank for 15 seconds, pause for 15 seconds, and repeat. If
the generator does not begin producing electricity after
approximately 90 seconds, the generator 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,
failed engine ignition, or the engine air filter is clogged.You
may need to contact your local service center for
assistance if you can’t remedy these problems.
Low Frequency
This fault is indicated by five blinks.This feature protects
devices connected to the transfer switch by shutting the
generator down if the engine runs slower than the preset
limit.
This condition may be potentially caused by a failed engine
governor.To remedy the problem, you should contact your
local service center for assistance.
This condition may also be potentially caused by excessive
loads on the generator.Turn off devices one at a time and
check the frequency.To remedy the problem, you may need
to contact your local service center for assistance.
Engine Overspeed
This fault is indicated by six blinks.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 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 immediately.
This condition is potentially caused by a failed engine
governor.To remedy the problem, you should contact your
local service center for assistance.
