OWNER ORIENTATION
This section provides Backup Power 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 Backup Power 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.
Your Briggs & Stratton Backup Power System is supplied
with this “Owners Manual” and a separate “Installation
Manual” (Generac part number 184957).These are both
important documents and should be retained by the owner
after the installation has been completed.
Installation Assistance
For the Home or Business Owner:
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.
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 BPS installation.
The factors mentioned above will have a direct
affect on the overall price of your Backup Power

NOTE: In some areas you may need to acquire electrical
Generator Location
The actual physical location of your backup generator has a
direct affect on:
permits for installing the Backup Power 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.
1. The amount of plumbing required to fuel your
generator.
Fuel Factors
2. The amount of wiring required to control and connect
your generator.
An important consideration affecting the entire installation
is the type of fuel used by your Backup Power 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).
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.
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.
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).
For proper engine function, the following fuel guidelines are
recommended:
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).
• Use clean, dry fuel, free of moisture or any particulate
material. Using fuels outside the following recommended
values may cause performance problems.

Gaseous Fuel System
• Ensure that all fuel pipe connections are tight, secure and
without leaks.
BEFORE INITIAL START-UP
Engine Oil
• Ensure that all shutoff valves are OPEN and that
adequate pressure is available.
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 on page 18
in “Checking Oil Level”.
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.
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.
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:
Oil Considerations
Your Backup Power System is equipped with an engine that
has been pre-run at the factory and does not require the
traditional “break-in” procedure.
• “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 sub-panel.
When utility power is restored, the system reconnects
utility power to the sub-panel, lets the engine ‘cool
down’, shuts off the generator, and waits for the next
utility power outage.
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 later in the
Maintenance section of this manual.
• “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.
Battery Connection
• “MANUAL” position starts the engine but does not
disconnect utility power from the sub-panel. It is used for
maintenance or diagnostic functions.
The Backup Power System is supplied with a 12Volt 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!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.
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.
The other controls and devices installed on the control
panel are described on page 10,“KnowYour System
Control Panel”.

Low BatteryVoltage
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
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.
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 battery only
with a genuine Generac part number 188443.
A light on the control panel called the Diagnostic LED will
turn on and off in a series of blinks.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 on the control panel and below:
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.

LowVoltage
Engine Overspeed
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 essential circuit sub-panel.
This fault is indicated by 6 blinks.This feature protects
devices connected to the essential circuit sub-panel by
shutting the generator down if its engine happens to run
faster than the preset limit.The overspeed fault is detected
as follows:
Remedy the problem (you may need to contact your
installer or Generac Technical Services for assistance), then
reset the Fault Detection system, as described above.
• 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.
Engine FailTo Start
This condition is caused by a failed engine governor.To
remedy the problem, you should contact your installer or
Generac Technical Services for assistance.When the
problem is corrected, reset the Fault Detection system as
described above.
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.
OilTemperature High
This fault is indicated by seven blinks.The contacts of the
temperature switch (Figure 6) are normally open. If the
engine temperature exceeds approximately 140°C (284°F),
the fault is detected and the engine shuts down.
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.
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.
Low Frequency
This fault is indicated by 5 blinks.This feature protects
devices connected to the essential circuit sub-panel by
shutting the generator down if its engine runs slower than
the preset limit.
Power During Fault Condition
Whenever the backup power 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 sub-panel loads.The generator is disconnected from
the automatic transfer switch for the duration of any
detected fault condition.
This condition is caused by a failed engine governor or by
excessive loads on the essential circuit sub-panel.To
remedy the problem, you may need to contact your
installer or Generac Technical Services for assistance.When
the problem is corrected, reset the Fault Detection system
as described above.
