Installation

We sincerely appreciate your patronage. For this reason, Briggs & 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 home generator system installations. Installations must strictly comply with all applicable codes, industry standards and regulations.

Your Briggs & Stratton 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 Briggs & Stratton 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.

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.

If you need more information, call [phone], 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.

Fuel Factors

This home generator system was factory tested and adjusted using natural gas. It can also operate on 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:

•Use clean, dry fuel, free of moisture or any particulate material. Using fuels outside the following recommended values may cause performance problems.

•For engines set up to run on propane vapor (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%.

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.

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.

Generator Clearances

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.

Essential Circuits

As a home generator owner, it is important that you clearly identify the circuits in your building that are “essential” to you.

It is also 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 generator for the duration of normal power interruption.

The wattage reference table that follows 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 your installation. This chart serves as a guide only. For exact wattage use an appropriate wattage meter.

BRIGGSandSTRATTON.COM

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 nameplate does not list 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 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 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 table 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.

In a utility outage, you need to ‘manage’ power distribution by turning off non-essential loads. 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

Delivery Inspection

Carefully inspect the home 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.

Operation

Important Owner’s Considerations

Engine Oil

notice

Any attempt to crank or start the engine before it has been properly serviced with the recommended coolant or oil will result in equipment failure.

•Refer to Maintenance in the Operator’s Manual and engine manual for coolant and oil fill information.

•Damage to equipment resulting from failure to follow this instruction will void engine and generator warranty.

This engine is shipped from the factory pre-run and filled with non-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 and ensure that engine is serviced as described in the engine operator’s manual.

NOTE: The use of multi-grade oil does not alter the required oil change intervals described in the engine operator’s manual.

Coolant System

This engine is shipped from the factory filled with a 50-50 mix of automotive (Dex-Cool™ orange) anti-freeze

and water. This will provide optimum year round protection against freezing, boiling and corrosion. The coolant system incorporates a water heater that operates when ambient temperature is below 80ºF AND utility power is present at the transfer switch. Before starting the engine, check coolant level as described in the engine operator’s manual.

Battery

The installer must supply a sealed, rechargeable 12 Volt DC, 650 Cold Cranking Amps (CCA) 55 amp hour starting battery. The battery may not be at full charge when installed. If battery voltage is below 12 Volts, charge the battery. See Battery in the Maintenance section for details.

15 Amp Fuse

The generator’s 15 Amp fuse is critical to correct system operation. 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.

caution

With the system 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 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.

Checking Automatic Operation

To check the system for proper automatic operation, proceed as follows:

1.Turn OFF main distribution panel circuit breaker sending power to automatic transfer switch.

The engine will crank and start when utility voltage is lost and the sensor has timed out. Let the system go through its entire automatic operation sequence.

2.With generator output supplying its loads, turn ON main distribution panel circuit breaker that supplies utility power to Automatic Transfer Switch.

3.The automatic transfer switch will transfer loads back to 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.

13

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).

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 Automatic 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.

Maintenance

Servicing the System

To service the home generator system:

1. Remove 15 Amp fuse from control panel. 2, Set control panel System switch to OFF.

3.Set the generator’s main circuit breaker to its OFF position.

4.Utility voltage is present. Disconnect power before servicing by removing the two 10 Amp fuses from the transfer switch.

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 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 5 seconds or more. Remedy the fault condition, then return the home generator to service by placing the system switch in the AUTO position.

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.

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 which 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 a Briggs & Stratton 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 a Briggs & Stratton Authorized Dealer.

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 a Briggs & Stratton 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:

•If the generator output frequency is 65-70 Hz, after three seconds, the generator will shut down.

•If the generator output frequency is greater than 70 Hz, the generator will shut down immediately.

This condition is caused by a failed engine component. To remedy the problem, contact your installer or a Briggs & Stratton Authorized Dealer.

15

High Temperature (FC_7)

This fault is indicated by fault code FC_7 and seven blinks on the LED indicator. The contacts of the coolant temperature switch are normally open. If the engine coolant temperature exceeds approximately 115.5°C (240°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 or coolant level, or debris in the engine compartment or radiator.

To resolve the problem, let the engine cool down and remove any accumulated debris and obstructions. Ensure that the 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 a Briggs & Stratton 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.

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.

NOTE: DO NOT use direct spray from a garden hose to clean generator. Water can enter the engine and generator and cause problems.

Engine Maintenance

An engine manual was packaged with this system. Please refer there for all engine-related maintenance topics. However, proper engine cooling and lubrication are so important we give them special mention here.

Engine Oil

The system is filled with the recommended non-synthetic oil (API SL 10W-30W). This allows for system operation in a wide range of temperature and climate conditions.

NOTE: Refer to the engine operator’s manual for recommended oil change intervals.
