INSTALLATION
OWNER ORIENTATION
This section provides the Home Standby Generator owner 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 the Home Standby Generator. A thorough understanding of these options will provide fundamental control over the cost of installation, as well as ensure 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. As the distance from the existing electrical service and gaseous fuel supply increases, so must the piping and wiring materials. This is necessary to comply with local codes, overcome electrical voltage drops and gaseous fuel pressure drops.
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.
INSTALLATION PROCEDURES
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.
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 generator.
Fuel Factors
An important consideration affecting the entire installation is the type of fuel used by your Home Standby Generator. The generator was factory tested and adjusted using natural gas as a fuel. liquid propane vapor (LP) may also be used as fuel by installing the included conversion kit.
For proper generator performance, the following fuel guidelines are recommended:
In engines set up to run on liquid 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%.

INSTALLATION
Essential Circuits
Consult with owner to clearly identify the circuits in building that are "essential".
It is important that you understand which circuits the owner wants 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 the owner with their decision-making process. It provides the wattage used by many ordinary household devices. Use it as a guide when selecting essential circuits. Review this information with the owner and convey any technical considerations that might affect the cost of 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 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 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.

INSTALLATION
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 generator’s altitude above sea level and the ambient temperature range when determining total generator load.
Disconnect Box Mounting Guidelines
The disconnect box is a NEMA Type 3R enclosure suitable for outdoor use. Installations must strictly comply with all applicable codes, industry standards and regulations.
Guidelines for mounting the disconnect box include:
•The disconnect box must be installed with appropriate hardware for conduit connections.
•Install disconnect box on a firm, sturdy supporting structure, making sure it is level and plumb.
•NEVER install disconnect box where any corrosive substance might drip onto enclosure.
•Protect disconnect box at all times against excessive moisture, dust, dirt, lint, construction grit and corrosive vapors.

INSTALLATION
THE GASEOUS FUEL SYSTEM
WARNING
Propane and Natural Gas are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
•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 System owner(s) and convey any technical considerations that might affect their installation plans before applying these general guidelines.
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.
•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.
•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.
Fire or explosion can cause severe burns or death.
•Before placing the Home Generator System into service, the fuel system lines must be properly purged and leak tested.
•NO leakage is permitted.
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 that meets UL 569 and CSA 8.3 (supplied) between the Home Generator System Fuel Inlet port and rigid piping to prevent thermal expansion or contraction from causing excessive stress on the piping material.
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.
Consider the following factors when planning to install the fuel supply system:
The Home Generator System engine is fitted with a fuel mixer system that meets the specifications of the California Air Resources Board for “tamper-proof” dual fuel systems. The unit will run on natural gas or liquefied propane vapor.
•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 System. 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. LP fuel supply pressure should be 11 to 14 inches of water (in. W.C.) at full load.
13
INSTALLATION
The Home Generator System unit 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.
The manometer port permits temporary installation of a manometer (Figure 5), to ensure that the engine receives the correct fuel pressure to operate efficiently throughout its operating range.
Figure 5 — Temporary Manometer Installed
When the initial test runs are completed, the manometer is removed and the port is plugged. A typical final fuel connection assembly is shown in Figure 6.

Generator AC Connection System
A single-phase, three-wire AC connection system is used in the Home Standby Generator. The stator assembly consists of a pair of stationary windings with two leads brought out of each winding. The junction of leads 22 and 33 forms the neutral lead. A complete schematic and wiring diagram can be found on pages 26-27.
NOTE: Neutral is not bonded to ground at generator.
Grounding the Generator
Ground the Home Generator System per applicable codes, standards, and regulations. The GND lug is located in the disconnect box.
Generator Control Circuit Connection
Control circuit interconnections consist of "240V AC Utility" leads. These two leads must be routed in conduit. Control lead functions are briefly described as follows:
•Leads deliver utility power to generator’s circuit board, oil warmer, optional battery warmer and charge the battery.
Using installer-supplied minimum 300V, 14 AWG copper wire, connect control circuit terminals in the disconnect box to the Transfer Switch.
Remote Diagnostic LED Plate
The light on the remote LED plate is referred to as the Diagnostic LED. The LED will stay lit indicating the generator is in ready mode and will turn on and off in a series of blinks if certain faults are detected in the Home Standby Generator. A mounting plate is supplied so that it can be installed at a convenient indoor location. The owner will use it to observe the status of the Home Standby Generator. Consult with the owner for a convenient location.
To install the remote diagnostic LED plate:
•Mount installer-supplied electrical box to wall.
•Using installer-supplied wire, connect the remote LED leads to the “Remote Status Light” in disconnect box.
NOTE: LED leads are polarity sensitive.
• Attach mounting plate to electrical box.
Refer to the section Fault Detection System for operation.
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.
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 engine manual for oil fill information.
•Damage to equipment resulting from failure to follow this instruction will void warranty.
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 generator is filled with synthetic oil (API SJ/CF 5W30W). This allows for generator 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.
17
INSTALLATION
Battery Connection
The Home Standby Generator is supplied with a 12 Volt DC, AGM type, 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 unit’s 15 Amp fuse, which isolates the battery and prevents the unit from starting, has been removed for shipping. The battery will lose some charge charge prior to installation of the generator. If battery voltage is below 12 Volts, charge the battery.
IMPORTANT: If battery voltage is below 5 Volts, it may not take a charge and you will need a new battery.
WARNING
Storage batteries give off explosive hydrogen gas during recharging.
Slightest spark will ignite hydrogen and cause explosion.
Battery electrolyte fluid contains acid and is
extremely caustic.
Contact with battery contents will cause severe chemical burns.

2.Remove the 15 Amp fuse from the control panel.
3.Service or replace battery as required.
4.Connect the red battery cable to the battery positive terminal (indicated by POSITIVE, POS, or (+)).
5.Connect the negative battery cable to the negative battery terminal (indicated by NEGATIVE, NEG, or (-).
6.Ensure hardware on both positive and negative battery terminals is secure.
7.Reinstall the 15 Amp fuse in the control panel.
8.Set the generator's “AUTO/OFF/MANUAL” switch to
AUTO.
18
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.
6.Repeat process until engine starts.
7.Listen for unusual noises, vibration or other indications of abnormal operation. Check for oil leaks while the engine runs.
8.Let engine warm up for about five minutes to allow internal temperatures to stabilize. Then, set generators main circuit breaker to ON (or closed) position.
FUEL SYSTEM SELECTION
The engine of your Home Standby Generator is factory calibrated to run on natural gas (NG). It may also be operated on liquid propane vapor (LP).
To configure the fuel system for LP use:
1.LP fuel inlet pressure must be between 11 and 14 inches water column.
2.Set AUTO/OFF/MANUAL switch to OFF.
3.Pull service disconnect from disconnect box.
4.Remove 15 Amp fuse.
5.Change main jet in fuel mixer following instruction sheet provided in LP conversion kit.
6.Reinstall 15 Amp fuse.
7.Reinstall service disconnect in disconnect box.
8.Set AUTO/OFF/MANUAL switch to AUTO.
9.Reset exercise timer following instructions in Setting Exercise Timer.
The generator is now ready to operate automatically using LP fuel. With a fixed main jet for LP gas, there is no need to perform any engine adjustments for LP operation.
INITIAL START-UP (NO LOAD)
Begin testing the generator without any electrical loads connected, as follows:
1.Set AUTO/OFF/MANUAL switch to OFF.
2.Set generator’s main circuit breaker to OFF (open) position.
3.Install 15 Amp fuse in control panel.
4.Set AUTO/OFF/MANUAL switch to MANUAL.
NOTE: When the Home Standby Generator is started for the very first time, it will require that air in the gaseous fuel lines be purged. This may take a few minutes.
5.DO NOT crank engine for more than 15 seconds, then pause for 15 seconds to reduce heat in starter.
9.Connect an RMS AC voltmeter and a frequency meter to check generator output at load side of circuit breaker. Voltage should be 230-240 Volts, frequency should be 62.0 - 62.5 Hz.
10.Check generator output between one generator connection lug and neutral lug, then between other generator connection lug and neutral lug. In both cases, voltage reading should be between 115-120 Volts.
11.Set AUTO/OFF/MANUAL switch to OFF. Engine will shut down.
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 70 percent of the nominal supply voltage, the sensor energizes a six second timer.
•Once the timer has expired, the generator will 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 generator will go to engine cool-down.
19
INSTALLATION
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 generator run time is five minutes.
SETTING EXERCISE TIMER
The Home Standby Generator is equipped with an exercise timer that will start and exercise the generator 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” (see page 7). On the specific day and time the switch is pressed, the control board is programmed. This date and time is then used to automatically initiate the generator exercise cycle.
To perform the Set Exercise procedure:
1.Choose day and time you want Home Standby Generator to exercise.
2.On that day and time, set AUTO/OFF/MANUAL switch to OFF position.
3.Press and hold down “Set Exercise” switch for two seconds.
4.Set 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 hour).
NOTE: “Set Exercise” will only work if the unit is in the Automatic mode and this exact procedure is followed.
If you want to change the day and time the unit exercises, simply perform the “Set Exercise” procedure at the day and time you want it to take place.
INSTALLATION INSPECTION
Before placing the Home Standby Generator into service, inspect the entire installation carefully. Ensure that any scratches or broken paint on the inside or outside of the enclosure are touched up with the supplied paint.
Complete the ”Installation Checklist” as you make the inspection. Ensure all items have been filled-in and all signatures have been obtained. Instruct the owner to mail the white copy to:

AUTOMATIC OPERATION
To select automatic operation, do the following:
1.Set service disconnect or main distribution panel circuit breaker that sends utility voltage to transfer switch to
ON.
2.Set generator’s main circuit breaker to ON position.
3.Set AUTO/OFF/MANUAL switch to AUTO.
Checking Automatic Operation
To check the system for proper automatic operation, proceed as follows:
1.Turn OFF service disconnect or main distribution panel circuit breaker sending power to automatic transfer switch.
The generator 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 generator output supplying load, turn ON service disconnect or main distribution panel circuit breaker that supplies utility power to automatic transfer switch.
3.Automatic transfer switch will transfer loads back to utility power after five minute minimum run time and utility is restored.
4.Generator will run for approximately an additional minute for engine cool down, then shut down.
5.Install control panel access door and roof following instructions in Removable Roof and Access Door.
NOTE: If generator does not shut down after approximately 10 minutes, put AUTO/OFF/MANUAL switch to OFF and contact your 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.Remove roof by removing four screws and lifting off.
2.Remove screw at top of control panel access door.
3.Pull access door outward (away) from unit while pulling door upward and out of base. Door will come free of generator enclosure.
4.Set AUTO/OFF/MANUAL switch to OFF.
5.Set generator’s main circuit breaker to OFF position.
6.Pull service disconnect from disconnect box.
7.Remove 15A fuse from control panel.
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, over speed, and other conditions.
A light on the remote LED plate is called the Diagnostic LED. The LED will turn on and off in a series of blinks if certain problems are detected in your Home Standby Generator. The blink pattern is repeated with a brief pause between each series. The number of blinks in the series indicates the detected fault, as listed on the mounting plate and as follows:
21
OPERATION
Number of LED Flashes |
Fault Description |
2 |
Low oil pressure |
4 |
Engine failed to start |
5 |
Low frequency |
6 |
Engine overspeed |
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.
Install the battery after it has been fully recharged or replaced, connecting the NEGATIVE cable last. Install the 15 Amp fuse.
WARNING
Battery posts, terminals and related accessories contain lead and lead compounds - chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
Low Oil Pressure
This fault is indicated by two blinks. The generator is equipped with an oil pressure switch (Figure 11). Should oil pressure drop, switch contacts close and the engine is shut down.
Figure 11 — Low Oil Pressure
Oil Pressure Switch
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, generator will start, then shut down after approximately 10 seconds and diagnostic LED will flash. In this case, contact your local service center.
Engine Fail To Start
This fault is indicated by four blinks. This feature prevents the generator from damage by continually attempting to start. Each time the system is directed to start, the generator will crank for 15 seconds, pause for 15 seconds, crank for
15 seconds, pause for 15 seconds, and repeat. If the generator does not begin producing electricity after approximately 90 seconds, the generator 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, failed engine ignition, or the engine air filter is clogged. You may need to contact your local service center for assistance if you can’t remedy these problems.
Low Frequency
This fault is indicated by five 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 may be potentially caused by a failed engine governor. To remedy the problem, you should contact your local service center for assistance.
This condition may also be potentially caused by excessive loads on the generator. Turn off devices one at a time and check the frequency. To remedy the problem, you may need to contact your local service center for assistance.
Engine Overspeed
This fault is indicated by six 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 immediately.
This condition is potentially caused by a failed engine governor. To remedy the problem, you should contact your local service center for assistance.
