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.

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 (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 propane (LP) gas, 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 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.

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.

Delivery Inspection

After removing the carton, carefully inspect the Home Standby 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. If loss or damage is noted after delivery, separate the damaged materials and contact the carrier for claim procedures. Missing or damaged parts are not warranted.

Approved Transfer Switches

The Home Standby Generator should be used ONLY with Briggs & Stratton Power Products UL approved Transfer Switches. Connection to any other transfer switch will void your generator warranty.

•Keep at least 5 ft. (152 cm) clearance on all sides of generator including overhead.

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

WARNING

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

Breathing carbon monoxide can cause nausea, fainting or death.

•Operate generator ONLY outdoors.

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

•Install the unit outdoors ONLY.

•Place the unit in a prepared location that is flat and has provisions for water drainage.

•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.

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 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.

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.

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.

•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 Standby 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

Consult with the Home Standby 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 Standby 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.

install the fuel supply system:

The Home Standby Generator 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.

•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 Standby 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. LP fuel supply pressure should be 11 to 14 inches of water (in.W.C.) at full load.

The Home Standby Generator 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 on page 18.

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.

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.

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.

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 70 percent of the nominal source voltage, a time delay starts timing and the generator 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 generator run time is five minutes.

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

20

Briggs & Stratton Power Products Home Standby Generator

Installation, Start-Up and Operator’s Manual

between each series.The number of blinks in the series indicates the detected fault, as listed on the mounting plate and as follows:

Number of LED Flashes	Fault Description
2	Low oil pressure
4	Engine failed to start
5	Low frequency
6	Engine overspeed

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.

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.

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.

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.

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.

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.
