OWNER ORIENTATION
This section provides Home Standby 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 Standby 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, 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 Standby
Generator installation.
6
Briggs & Stratton Power Products Home Generator
Owners Manual
NOTE: In some areas you may need to acquire electrical
permits for installing the Home 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 system.
Fuel Factors
An important consideration affecting the entire installation
is the type of fuel used by your Home Standby Generator.
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 HSG 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. 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).

• 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 is extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.

Essential Circuits
As a Home Standby Generator 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 Standby Generator 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 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
Standby Generator:
• Figure the watts required to start the largest motor.
• Add that to the total running watts of all other
connected loads.

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 Home 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 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 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 unit’s
15 Amp fuse, which isolates the battery and prevents the
unit from starting, has been removed for shipping.
NOTE:With the battery installed, all wiring to transfer
switch and Home Standby 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 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).
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.
• 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
• 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 Standby
Generator.
• Contact your gas utility or the system installer for assistance
in determining the source of the smell.
Propane and Natural Gas is extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.

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 AUTO/OFF/MANUAL 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 once 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 generator does not shut down after 10 minutes,
put AUTO/OFF/MANUAL switch to OFF and contact your
installer or local service center.
This completes the test procedures for automatic
operation.The Home Standby Generator 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 AUTO/OFF/MANUAL 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 Standby 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).
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
Standby Generator 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 for two
seconds.
4. 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 (+/- 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 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.
• To prevent possible injury that might be caused by such sudden
starts, always set the AUTO/OFF/MANUAL switch to OFF.
• Remove the 15 Amp fuse before working on or around the
generator or transfer switch.
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.

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 HSG.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 as follows:
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 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.
15
Briggs & Stratton Power Products Home Generator
Owners Manual
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 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 two blinks.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 10 seconds and diagnostic LED
will flash. In this case, contact an authorized service facility.
Low Voltage (Generator)
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 Home Standby
Generator is overloaded.
To remedy the problem, contact your local service center.
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.
Low Frequency
This fault is indicated by 5 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 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 6 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 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 seven blinks.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.
