INTRODUCTION

Thank you for your purchase of a Briggs & Stratton

Home Standby Generator (HSG).This product is intended for use as an optional home standby system which provides an alternate source of electric power and to serve loads such as heating, refrigeration systems, and communication systems that, when stopped during any power outage, could cause discomfort, or the like.This product does not qualify for emergency standby as defined by NFPA 70 (NEC).

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 licensed electrical and

plumbing contractors should attempt

HSG installations.

Installations must strictly comply with

all applicable codes, industry standards

and regulations.

Your Briggs & Stratton Home Standby Generator is supplied with this “Operator’s Manual” and a separate “Installation Manual” (part number 192385GS).These are important documents and should be retained by the owner after the installation has been completed.

Installation Assistance

For the Home 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 HSG installation.

To arrange for proper installation, contact the store at which you purchased your Briggs & Stratton Home Standby Generator, your dealer, a licensed electrician or your utility power provider.

The HSG Warranty is V

OID unless the system

is installed by licensed 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 Standby Generator.This Operator’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 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.

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.

Briggs & Stratton Power Products Home Generator

Operator’s Manual

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

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.

Home Standby Generator Location

Before installing generator, consult with homeowner and convey the following guidelines which may affect the desired location.

Generator Clearances

Place generator in a well ventilated area which will allow for removal of deadly exhaust gas. 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 (Figure 1). Prevailing winds and air currents should be taken into consideration when positioning generator.

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 in a location where sump pump discharge,

rain gutter down spouts, roof run-off, landscape irrigation, or water sprinklers will not flood the unit or spray the enclosure and enter any air inlet our outlet openings.

• Install the unit where the location of any services such as

phone, electrical, fuel, air conditioning, irrigation, including covered, concealed and underground services will not be affected or obstructed.

• 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.

WARNING

• Operate generator ONLY outdoors.

• Keep exhaust gas from entering a confined area through windows, doors, ventilation intakes or other openings.

Running generator gives off carbon monoxide, an odorless, colorless, poison gas.

Breathing carbon monoxide will cause nausea, fainting or death.

WARNING

Briggs & Stratton Power Products Home Generator

Operator’s Manual

• 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 Home 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

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.

Briggs & Stratton Power Products Home Generator

Operator’s Manual

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 Home 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 Home 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 system’s altitude above sea level and the ambient temperature range when determining total generator load.

IMPORTANT:When using the 100 Amp or 200 Amp transfer switch with the Home Standby Generator, you must

turn off any non essential loads. Failure to turn off non essential loads could overload the generator causing it to shut down. Some examples of non essential loads are as follows:

• Pool pump

• Hot tub

• Electric hot tub and/or pool heaters

• Central air conditioners

• Electric hot water heaters

• Electric range and/or oven

• Arc welder

• Non essential electric heaters

UNPACKING

Refer to the Installation Manual for detailed unpacking instructions, if desired.

Operator’s Manual

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 operator’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 operator’s manual.

Battery Connection

The Home Standby Generator is supplied with a 12Volt DC 33 Amp-Hour, valve regulated 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 unit from starting during 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.

Operator’s Manual

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.

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.

Operator’s Manual

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.
