Installation
We sincerely appreciate your patronage. For this reason, we
have made every effort to provide for a safe, streamlined
and cost-effective installation. Because each installation is
unique, it is impossible to know of and advise the trade of all
conceivable procedures and methods by which installation
might be achieved. Neither could we know of possible
hazards and/or the results of each method or procedure. For
these reasons,
Only current licensed electrical and plumbing contractors
should attempt home generator system installations.
Installations must strictly comply with all applicable
codes, industry standards and regulations.
Your home generator is supplied with this “Operator’s
Manual” and a separate “Installation Manual”. These are
important documents and should be retained by the owner
after the installation has been completed.
For the Home Owner:
To help you make informed choices and communicate
effectively with your installation contractor(s),
Read and understand Owner Orientation in this
manual before contracting or starting your home
generator installation.
To arrange for proper installation, contact the store at which
you purchased your home generator, your dealer, a licensed
electrician or your utility power provider.
The home generator warranty is VOID unless the
system is installed by licensed electrical and
plumbing professionals.
Every effort has been made to ensure that information in this
manual is accurate and current. However, we reserve the
right to change, alter, or otherwise improve the product and
this document at any time without prior notice.
The Emission Control System for this generator is warranted
for standards set by the U.S. Environmental Protection
Agency and by the California Air Resources Board (CARB).
For the Installing Dealer/Contractor:
For most applications, the Installation manual contains
all the information required to properly install and start
the home generator. This Operator’s Manual describes
essential circuit selection, routine operation and owner
maintenance procedures.

743-4115, between 8:00 AM and 5:00 PM CT.
Owner Orientation
This section provides home generator owners with the
information necessary to achieve the most satisfactory and
cost effective installation possible.
The illustrations are for typical circumstances and are meant
to familiarize you with the installation options available with
your home generator. A thorough understanding of these
options will provide fundamental control over the cost of
your installation, as well as ensure your final satisfaction
and security.
Federal and local codes, appearance, noise levels, fuel types,
and distances are the factors that must be considered when
negotiating with an installation professional. Remember
that as the distance from the existing electrical service and
gaseous fuel supply increases, and the number of 90 degree
bends in the fuel supply increases; 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 installation.
NOTE: In some areas you may need to acquire electrical
permits for installing the home generator, building permits
for installing gas lines, and permits for noise allowances.
Your installer should check your local codes AND obtain the
permits before installing the system.
8 BRIGGSandSTRATTON.COM
Fuel Factors
An important consideration affecting the entire installation is
the type of fuel used by your home generator. The system
was factory tested and adjusted using either natural gas
or liquid propane (LP vapor). For proper engine function,
factors that are inherent to each of these fuels, your
location and the duration of possible utility interruptions are
important considerations in the following fuel guidelines:
• Useclean,dryfuel,freeofmoistureorany
particulate material. Using fuels outside the
following recommended values may cause
performance problems.
• Inenginessetuptorunonpropane(LP),commercial
grade HD5 propane with a minimum fuel energy of
2500 BTUs/ft3 with maximum propylene content of
5% and butane and heavier gas content of 2.5% and
minimum propane content of 90%.
Power Decrease at High Altitude or High Temperature
Air density is less at high altitudes, resulting in less available
engine power. Specifically, engine power will decrease 3.5%
for each 1,000 feet (300 meters) above sea level and 1% for
each 10° F (5.6°C) above 77°F (25°C). Make sure you and
your installer consider these factors when determining total
generator load.
Generator Location
The actual physical location of your home generator has a
direct affect on:
1. The amount of plumbing required to fuel
your generator.
2. The amount of wiring required to control and connect
your generator.
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.
The generator must be installed outdoors. DO NOT install
generator where exhaust gas could accumulate and enter
inside or be drawn into a potentially occupied building.
Ensure exhaust gas is kept away from any windows, doors,
ventilation intakes or other openings that can allow exhaust
gas to collect in a confined area. Prevailing winds and air
currents should be taken into consideration when positioning
generator. See the Installation Manual for full details on safe
generator location.
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.
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: Propane and Natural Gas are extremely
flammable and explosive.
Fire or explosion can cause severe burns
or death.
The home generator is equipped with an automatic safety •
gas “fuel shut-off” valve.
DO NOT operate the equipment if the “fuel shut-off” valve •
is missing or inoperative.

Operation
Important Owner’s Considerations
Engine Oil
This engine is shipped from the factory pre-run and filled
with synthetic oil (API SL 10W-30W). This allows for system
operation in a wide range of temperature and climate
conditions. Before starting the engine, check oil level as
described in the engine manual.
Battery
The home generator is supplied with a sealed, lead-acid,
rechargeable, 12 Volt DC 55 Amp-Hour, valve regulated
battery. It is installed in the unit and the battery cables are
connected at the factory.
With the battery installed, all wiring to transfer switch and
home generator completed, utility power supplied to the
Automatic Transfer Switch, and the unit in AUTO mode,
the battery receives a trickle charge while the engine is not
running. The trickle charge cannot be used to recharge a
battery that is completely discharged.
WARNING: Contact with muffler and engine parts can
result in serious burns.
DO NOT touch hot parts and AVOID hot exhaust gases.•
Allow equipment to cool before touching.•
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 • Maintenance in the Operator’s Manual and engine
manual for oil fill information.
Damage to equipment resulting from failure to follow this •
instruction will void engine and generator warranty.

15 Amp Fuse
The generator’s 15 Amp fuse is critical to correct system
operation. The 15 Amp fuse was removed at the factory to
prevent the unit from starting during shipping. Your installer
will ensure the fuse is properly installed upon completion of
the installation.
Automatic Operation
To select automatic operation, do the following:
1. Confirm 15 Amp fuse is installed in control panel.
2. Set the main distribution panel circuit breaker that
sends utility voltage to the transfer switch to ON.
3. Set the generator’s main circuit breaker to its
ON position.
4. Set the control panel system switch to AUTO.
Checking Automatic Operation
To check the system for proper automatic operation, proceed
as follows:
1. Turn OFF the service disconnect or main distribution
panel circuit breaker sending power to the automatic
transfer switch.
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 will now start automatically and will
supply power to the transfer switch when utility power
is lost.
Setting Exercise Timer
The home generator is equipped with an exercise timer that
will start and exercise the system once every seven days.
During this exercise period, the unit runs for approximately
20 minutes and then shuts down. Electrical load transfer
DOES NOT occur during the exercise cycle (unless an utility
power outage occurs during the cycle).
A button on the control panel is labeled “Set Exercise” (see
System Control Panel). The specific day and the specific
time of day this button is pressed is programmed into the
control board memory. This date and time is then used
to automatically initiate the system exercise cycle. The
“SET EXERCISE” legend on the control panel will flash until
the set exercise cycle is set.
To perform the Set Exercise procedure:
1. Choose the day and time you want your home
generator to exercise.
2. On that day and time, press and hold down the “SET
EXERCISE” button for three seconds.
NOTE: “SET EXERCISE” will flash until the button is
pressed for three seconds, then “SET EXERCISE” will
illuminate for 5 seconds, and finally turn off.
3. The unit will then start and run it’s 20 minute
exercise cycle.
For example, if you press the “Set Exercise” button on
Sunday morning at 10:00 AM, the unit will run an immediate
exercise cycle and an exercise cycle every following Sunday
at 10:00 AM (+/- 1/2 hour).
NOTE: “Set Exercise” will only work if the unit is in the AUTO
mode and this exact procedure is followed. The exerciser will
need to be re-set if the 15 Amp fuse is removed or changed,
or if the 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 system switch set to AUTO,
the engine may crank and start at any time
without warning.
To prevent possible injury that may be caused by such •
sudden starts, always set the system switch to OFF if
performing maintenance on the system.
Remove the 15 Amp fuse before working on or around •
the generator or transfer switch.
14 BRIGGSandSTRATTON.COM
Maintenance
Servicing the System
Before performing any generator maintenance, always
perform the following steps:
1. Remove 15 Amp fuse from control panel.
2. Set control panel system switch to OFF.
3. Set generator’s circuit breaker to its OFF position.
4. Utility voltage is present at generator control panel.
Disconnect power before servicing control panel by
removing the fuses from the transfer switch.
5. After all servicing has been completed, replace 15 Amp
fuse in control panel and reset exercise timer. See
Setting Exercise Timer in Operation.
Fault Detection System
The generator may have to run for long periods of time
with no operator present. For that reason, the system is
equipped with sensors that automatically shut down the
generator in the event of potentially damaging conditions,
such as low oil pressure, high temperature, over speed, and
other conditions.
The generator’s control panel has a digital display that shows
fault codes, like “FC_1”. The table below lists the detected
fault, the fault code as displayed on the control panel, and
the number of LED flashes (also described as ‘blinks’) seen
on the remote LED indicator.
Fault Description Fault Codes LED Flashes
Low battery voltage FC_1 1
Low oil pressure FC_2 2
Low voltage FC_3 3
Engine fails to start FC_4 4
Low frequency FC_5 5
Engine overspeed FC_6 6
High temperature FC_7 7
Transfer switch fault FC_8 8
The remote LED indicator is installed at a convenient inside
location. The LED will remain lit when the generator is in
AUTO. Should a system fault be detected, the LED will turn
on and off in a series of blinks that identify the problem. The
blink pattern is repeated with a brief pause between each
series of blinks.
Reset Fault Detection System
The operator must reset the fault detection system each time
it activates. To do so, place the control panel system switch
in the OFF position for 30 seconds or more. Remedy the
fault condition, then return the home generator to service by
placing the system switch in the AUTO position, installing
the 15 Amp fuse, and resetting the exercise timer. See
Setting Exercise Timer in Operation.
A description of each fault and suggested remedies are as
follows:
No LED - Discharged Battery
If there is a detected fault condition but the LED is
not blinking, this is because the battery is completely
discharged. To remedy the problem, remove the 15 Amp
fuse and disconnect the battery from the generator. Take
the battery to a local battery store for analysis. Replace the
battery after it has been fully recharged, connecting the
NEGATIVE cable last. Then install the 15 Amp fuse in the
control panel.
NOTE: With the battery installed, all wiring to transfer switch
and home generator completed, utility power supplied to
the Automatic Transfer Switch, and the unit in AUTO mode,
the battery receives a trickle charge while the engine is not
running. The trickle charge is not able to recharge a battery
that is completely discharged. See Battery in Maintenance.
Low Battery Voltage (FC_1)
This fault is indicated by fault code FC_1 and one blink on
the LED indicator. This condition occurs if the generator
cannot start because the starting battery output power is
below that needed to crank the engine. Causes for this
problem may be a faulty battery or battery charge circuit.
To remedy the problem, contact your local service center to
check the battery charge output. Remove the 15 Amp fuse
and disconnect the battery from the generator. Take the
battery to a local battery store for analysis.
Replace the battery after it has been fully recharged,
connecting the NEGATIVE cable last. Then install the 15 Amp
fuse in control panel and reset exercise timer. See Setting
Exercise Timer in Operation.
Low Oil Pressure (FC_2)
This fault is indicated by fault code FC_2 and two blinks on
the remote LED indicator. The unit is equipped with an oil
pressure switch that uses normally closed contacts held
open by engine oil pressure during operation. Should oil
pressure drop below the 8 psi range, switch contacts close
and the engine is shut down.
To remedy the low oil pressure condition, add the
recommended oil to the FULL mark on the dipstick.
If the low oil pressure condition still exists, the engine will
start, then shut down again. The fault code will appear and
the LED will flash. In this case, contact an Authorized Dealer.
Low Voltage (Generator, FC_3)
This fault is indicated by fault code FC_3 and three blinks on
the LED indicator. This condition is caused by a restriction in
the fuel flow, a broken or disconnected signal lead, a failed
alternator winding, the control panel circuit breaker is open,
or the generator is overloaded.
To remedy the problem, contact your installer or an
Authorized Dealer.
15
Engine Fail To Start (FC_4)
This fault is indicated by fault code FC_4 and four blinks on
the LED indicator. This feature prevents the generator from
damaging itself if it continually attempts to start in spite
of another problem, such as no fuel supply. Each time the
system is directed to start, the unit will crank for 10 seconds,
pause for 10 seconds, and repeat. If the system does not
begin producing electricity after approximately 2 minutes,
the unit will stop cranking and the LED will blink.
Check to make sure the generator’s main circuit breaker is in
the ON position in order for the sensing leads to verify that
the unit is running.
The most likely cause of this problem is no fuel supply.
Check the internal and external fuel shut off valves to
ensure they are fully open. Other causes could be failed
spark plug(s), failed engine ignition, or the engine air filter
is clogged. You may need to contact your installer for
assistance if you can’t remedy these problems.
Low Frequency (FC_5)
This fault is indicated by fault code FC_5 and five blinks on
the LED indicator. This feature protects devices connected
to the transfer switch by shutting the generator down if
the engine runs slower than 55 Hz for three seconds. This
condition is caused by a failed engine component or by
excessive loads on the generator. To remedy the problem,
contact your installer or an Authorized Dealer.
Engine Overspeed (FC_6)
This fault is indicated by fault code FC_6 and six blinks on
the LED indicator. This feature protects devices connected
to the transfer switch by shutting the generator down if
the engine happens to run faster than the preset limit. The
overspeed fault is detected as follows:
• Ifthegeneratoroutputfrequencyis65-70Hz,after
three seconds, the generator will shut down.
• Ifthegeneratoroutputfrequencyisgreaterthan70Hz,
the generator will shut down immediately.
This condition is caused by a failed engine component.
To remedy the problem, contact your installer or an
Authorized Dealer.
High Temperature (FC_7)
This fault is indicated by fault code FC_7 and seven blinks
on the LED indicator. The contacts of the temperature
switch are normally open. If the engine temperature exceeds
approximately 149°C (300°F), the fault is detected and the
engine shuts down.
Common causes for this condition include running the
unit with access doors removed, obstructed air inlet or
exhaust port, low oil level, or debris in the engine cylinder
cooling fins.
To resolve the problem, let the engine cool down and remove
any accumulated debris and obstructions. Ensure that all
access doors are installed whenever the unit is running.
Transfer Switch Fault (FC_8)
This fault is indicated by fault code FC_8 and eight blinks on
the LED indicator (if transfer switch is equipped with fault
detection). The most likely cause of this fault is a blown fuse
in the transfer switch.
To remedy the problem, contact your installer or an
Authorized Dealer.
Generator Maintenance
The generator warranty does not cover items that have been
subjected to operator abuse or neglect. To receive full value
from the warranty, the operator must maintain the system as
instructed in the engine operator’s manual.
All adjustments should be made at least once each season.
Follow the requirements in the engine operator’s manual.
Generator maintenance consists of keeping the unit
clean. Operate the unit in an environment where it will
not be exposed to excessive dust, dirt, moisture or any
corrosive vapors. Cooling air louvers on the enclosure
must not become clogged with snow, leaves, or any other
foreign material. To prevent generator damage caused by
overheating, keep the enclosure cooling inlets and outlets
clean and unobstructed at all times.
Check the cleanliness of the unit frequently and clean when
dust, dirt, oil, moisture or other foreign substances are
visible on its exterior/interior surface. Inspect the air inlet
and outlet openings inside and outside the enclosure to
ensure air flow is not blocked.
NOTE: DO NOT use direct spray from a garden hose to clean
generator. Water can enter the engine and generator and
cause problems.
