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

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:

• 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), 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.

Unpacking Precautions

The unit is shipped bolted to its mounting pad, ready for installation. Avoid damage from dropping, bumping, collision, etc. Store and unpack carton with the proper side up, as noted on the shipping carton.

CAUTION

Installing the 15A fuse could cause the engine to start.

Observe that the 15 Amp fuse has been removed from

• the control panel for shipping.

DO NOT install this fuse until all plumbing and wiring has

• been completed and inspected.

Delivery Inspection

After removing the carton, carefully inspect the home generator for any damage that may have occurred during shipment.

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.

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.

IMPORTANT: When using the 100 Amp or 200 Amp transfer switch with the home 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

The Gaseous Fuel System

WARNING

Propane and Natural Gas are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

• Installed piping must be properly purged and leak tested, in accordance with applicable codes and standards.

WARNING

Propane and Natural Gas are extremely flammable and explosive.

LP gas is heavier than air and will settle in low areas.

• Natural gas is lighter than air and will collect in high

• areas.

The slightest spark can ignite these fuels and cause an

• explosion.

DO NOT light a cigarette or smoke.

•

The information provided below is to assist gaseous fuel system technicians in planning installations. In no way should this information be interpreted to conflict with applicable fuel gas codes. Consult with your local fuel supplier or Fire Marshall if questions or problems arise.

TO THE INSTALLER: Consult with the home generator

owner(s) and convey any technical considerations that might affect their installation plans before applying these general guidelines.

The following general rules apply to gaseous fuel system piping:

• The piping should be of a material that conforms to federal and local codes, rigidly mounted and protected against vibration.

• Piping should be protected from physical damage where it passes through flower beds, shrub beds, and other cultivated areas where damage could occur.

• Install the flexible, gaseous hose (supplied) between the home generator Fuel Inlet port and rigid piping to prevent thermal expansion or contraction from causing excessive stress on the piping material.

NOTE: Where local conditions include earthquake, tornado, unstable ground, or flood hazards, special consideration shall be given to increase strength and flexibility of piping supports and connections.

CAUTION

The supplied flexible gaseous pipe is not to be installed underground or in contact with the ground.

•

The entire flexible gaseous pipe must be visible for periodic inspection and must not be concealed within, contact, or run through any wall, floor, or partition.

• Piping must be of the correct size to maintain the required supply pressures and volume flow under varying generator load conditions with all gas appliances connected to the fuel system turned on and operating.

• Use an approved pipe sealant or joint compound on all threaded fittings to reduce the possibility of leakage.

Fire or explosion can cause severe burns or death.

Before placing the home generator into service, the fuel

• system lines must be properly purged and leak tested.

NO leakage is permitted.

•

Consider the following factors when planning to install the fuel supply system:

The home generator engine is fitted with a fuel mixer system that meets the specifications of the California Air Resources Board for “tamper-proof” fuel systems.

• A minimum of one accessible, approved manual shutoff valve shall be installed in the fuel supply line within 6 ft (1.8 m) of the home generator. A union or flanged connection shall be provided downstream from this valve to permit removal of controls.

• Natural gas fuel supply pressure at the generator’s fuel inlet port should be between 5 to 7 inches of water (in. W.C.) at full load with all gas appliances turned on and operating.

• LP gas fuel supply pressure should be 11 to 14 inches of water (in. W.C.) at full load with all gas appliances turned on and operating.

The Home Generator has been factory set to run on natural gas. If you need to change from natural gas to LP gas, the unit will need to be reconfigured, as described in Fuel System Selection.

It is recommended that the fuel connection incorporate the following components:

• A manual fuel shut-off valve located in the interior of the building.

• A manual fuel shut-off valve located outside the building, just before the generator unit.

• Where the formation of hydrates or ice is known to occur, piping should be protected against freezing. The termination of hard piping should include a sediment trap where condensate is not likely to freeze.

• A manometer port should be provided.

12 BRIGGSandSTRATTON.COM

The manometer port permits temporary installation of a manometer to ensure that the engine receives the correct fuel pressure to operate efficiently throughout its operating range.

NOTE: A digital manometer, P/N 19495, is available at your local Briggs & Stratton service center.

When the initial test runs are completed, the manometer is removed and the port is plugged. A typical final fuel connection assembly is shown here, where (A) is the fuel supply and (B) goes to the home generator.

Final Installation Considerations

Engine Oil

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 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 synthetic oil (API SJ/CF 5W-30W). This allows for system operation in the widest 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 synthetic oil does not alter the required oil change intervals described in the engine operator’s manual.

Battery

The home generator is supplied with a sealed, lead-acid, rechargeable, 12 Volt DC 33 Amp-Hour, 350 cold cranking amps (CCA), 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 system switch in the AUTO position, 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.

15 Amp Fuse

The generator’s 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.

Fuel Supply System

Ensure that all fuel pipe connections are tight, secure and without leaks.

Ensure that all gas line shutoff valves are OPEN and that adequate fuel pressure is available whenever automatic operation is desired.

Fuel System Selection

The engine of your Home Generator System is factory calibrated to run on natural gas (NG). It may also be operated on liquid propane (LP) vapor.

System Control Panel

Compare this Control Panel illustration with your generator to familiarize yourself with the location of these important controls:

A - Set Exercise Switch — Used to set the exercise cycle

start time and day-of-the-week. Exercise cycle only occurs in AUTO mode.

B - Circuit Breaker — Protects the generator from shorts

and other over-current conditions. Must be ON to supply power to the Automatic Transfer Switch.

C - 15 Amp Fuse — Protects the home generator DC control

circuits. If the fuse has ‘blown’ (melted open) or was removed, the engine cannot crank or start. Replace the fuse using only an identical ATO 15A fuse.

D - System Switch — This two-position switch is the most

important control on the system and is used as follows:

• “AUTO” position is the normal operating position. If a

utility power outage is sensed, the system will start the generator. When utility power is restored, AUTO lets the engine stabilize internal temperatures, shuts off the generator, and waits for the next utility power outage.

• “OFF” position turns off running generator, prevents

unit from starting and resets any detected faults.

E - Manual Over-Ride Switch — With system switch in

AUTO position, push the manual over-ride switch to start the generator. To turn off the generator, push and hold the manual over-ride switch again until engine stops.

F - Digital Display — Displays the total number of hours

the generator has been running and fault codes. Used to schedule maintenance tasks and for troubleshooting operational problems with the home generator. All fault conditions are described in Fault Detection System.

Operation

Automatic Operation Sequence

The generator’s control panel houses a logic control circuit board. This control board constantly monitors utility power source voltage. Should that voltage drop below a preset level, control board action will signal the engine to crank and start.

When utility source voltage is restored above a preset voltage level, the engine is signaled to shut down.

The actual system operation is not adjustable and is sequenced by sensors and timers on the control board, as follows:

Utility Voltage Dropout Sensor

• This sensor monitors utility source voltage.

• If utility source voltage drops below about 70 percent of the nominal supply voltage, the sensor energizes a 10 second timer. The timer is used to ‘sense’ brown-outs.

• Once the timer has expired, the engine will crank and start.

Utility Voltage Pickup Sensor

This sensor monitors utility power supply voltage. When that voltage is restored above 80 percent of the nominal source voltage, a time delay starts timing and the engine will go to engine cool-down.

Engine Cool-down Timer

• When the load is transferred back to the utility power source, the engine cool-down timer starts timing.

• The timer will run for about one minute, then the generator will stop.

• Minimum engine run time is 5 minutes.

Automatic Operation

To select automatic operation, do the following:

1. Set the 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 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.

•

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 the 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 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 when utility power is lost and will supply power to the transfer switch.

20 BRIGGSandSTRATTON.COM

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 then 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 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 system:

1. Set the system 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.

Fault Detection System

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 Low oil pressure FC_2 Low voltage Engine fails to start Low frequency Engine overspeed High temperature Transfer switch fault

The remote LED indicator is installed at a convenient inside location. The LED will remain lit when the generator is in AUTO. The LED will turn on and off in a series of blinks that correspond to the fault detected in your home generator. The blink pattern is repeated with a brief pause between each series of blinks.

FC_1 1

2 FC_3 3 FC_4 4 FC_5 5 FC_6 6 FC_7 7 FC_8 8

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 system switch in AUTO position, 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

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 ONLY with same type battery as described in Battery in Installation.

Replace the battery after it has been fully recharged, connecting the NEGATIVE cable last. Then install the 15 Amp fuse.

Low Oil Pressure

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 (A).

Reset Fault Detection System

The operator must reset the fault detection system each time it activates. To do so, place the 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:

22 BRIGGSandSTRATTON.COM

The oil pressure switch uses 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 the low oil pressure condition still exists, the engine will start, then shut down after about 20 seconds. The fault code will appear and the LED will flash. In this case, contact a Briggs & Stratton Authorized Dealer.

Low Voltage (Generator)

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

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 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.

Engine Overspeed

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 governor. To remedy the problem, contact your installer or a Briggs & Stratton Authorized Dealer.

High Temperature

This fault is indicated by fault code FC_7 and seven blinks on the LED indicator. The contacts of the temperature switch (A) are normally open. If the engine oil temperature exceeds approximately 148.9°C (300°F), the fault is detected and the engine shuts down.

Low Frequency

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 governor or by excessive loads on the generator. To remedy the problem, contact your installer or a Briggs & Stratton Authorized Dealer.

Common causes for this condition include running the unit with all access covers 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 the access covers are installed whenever the unit is running.

Transfer Switch Fault

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. 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.
