Generator Placement Shipment Contents Installation Factors to Consider The illustrations shown in this manual depict typical circumstances. They are meant to familiarize you with the installation options available for the generator. Always consider installation factors such as federal and local codes, appearance, noise levels, fuel types, and distances. As the distance increases from the existing electrical service and gaseous fuel supply, and the number of bends in the fuel supply increases, installers must make compensations for piping and wiring materials. These compensations are necessary to comply with local codes and overcome drops in electrical voltage and drops in gaseous fuel pressure. Delivery Inspection Avoid damage from dropping, bumping, or colliding with the shipping carton. After removing the carton, carefully inspect the generator for any damage that may have occurred during shipment. If an owner discovers loss or damage at the time of delivery, the owner should ask the person(s) making the delivery to document the loss or damage on the freight bill and aix a signature under the consignor’s memo of loss or damage.

• DO NOT run this product inside homes, garages, basements, crawl spaces, sheds, or other partially enclosed spaces, even if using fans or opening doors and windows for ventilation. Carbon monoxide can quickly build up in these spaces and can linger for hours, even after this product has shut o.

Figure 1 (A) Exhaust Outlet Side of Enclosure(B) Air Inlet Side of Enclosure Generator Location Considerations The installation location of the generator directly aects:

• The amount and size of the plumbing required to fuel the generator

• The amount and size of the wiring required to control and connect the generator

• The safety of the installation regarding exhaust gas and carbon monoxide hazards, fire risks, proximity to other utilities, and exposure to weather elements The Generator Locations section addresses specific location guidelines. The owner and installer must consult one another to determine how the site can aect installation costs and compliance with local codes and standards. Two critical safety concerns include carbon monoxide poisoning and fire. Reducing the Risk of Carbon Monoxide Poisoning In high concentrations, carbon monoxide (CO) can be fatal in minutes. However, the eects of lower concentrations can also be lethal. This gas poses serious dangers to humans and their animals because no one can smell, see, or taste it. Symptoms of exposure to CO include:

• Inability to think coherently

• Loss of physical coordination

• Tightness across the chest

Generator Placement Reducing the Risk of Carbon Monoxide Poisoning If you (or someone nearby) suers from any of the above symptoms, immediately seek fresh air and call for emergency medical help for possible carbon monoxide poisoning. If your carbon monoxide alarm sounds while using this product, immediately seek fresh air (even if you experience none of the previously mentioned symptoms). Carbon Monoxide Detectors Note: Installing functioning CO alarms indoors is the only way to recognize CO gas. Common smoke alarms do not detect CO gas and will not alert occupants of its presence. A CO detector is an electronic device that detects hazardous levels of CO. When a buildup of CO occurs, the detector will alert the occupants by sounding an alarm and by flashing a visual indicator light. By law many states require a home to have a functioning carbon monoxide (CO) detector. You must install and maintain carbon monoxide detector(s) indoors according to the manufacturer’s instructions and recommendations. Contact the local building inspection division for any relevant requirements regarding the use of CO detectors. See National Fire Alarm and Signaling Code (NFPA) 72 Code and Section R315 in the International Residential Code (ICC) for additional details. Potential CO Entry Points Operation Guidelines: Note: Operate this product only outdoors and in an area that will not allow this deadly exhaust gas to collect. Never operate this product inside homes, garages, basements, crawl spaces, sheds, under a deck, or other partially enclosed areas and understand that using fans and opening doors in these areas may not provide adequate ventilation. Carbon monoxide can quickly accumulate in these forbidden spaces and can remain in the air for several hours after this product has shut o. Installation Guidelines: Follow all illustrations in this manual when placing an enclosure. Always point the generator’s engine exhaust away from occupied areas. Never expose your neighbors’ homes to the engine exhaust flowing from your standby generator during the installation process. Never place the standby generator in any area where leaves or debris can accumulate. Generator exhaust can enter through windows, doors, and other openings of a structure. Understand that exhaust and CO can seep into a structure through the smallest openings. Not for Reproduction12 Part No. 80106286 Revision C Generator PlacementReducing the Risk of Carbon Monoxide Poisoning Protecting the Structure Check the structure to ensure that the sealing and caulking remains adequate enough to prevent air from leaking in or out. Examine the structure for voids, cracks, or openings surrounding windows, doors, soits, pipes, and vents, as these areas can permit exhaust gas and CO to enter the structure.

Generator Placement Reducing the Risk of Carbon Monoxide Poisoning The following table includes some examples of potential entry points for CO gas.

Windows and doors Openings that are part of a structure’s architecture can permit fresh air and CO into the structure, especially when open. B Garage door An open or improperly unsealed garage door can allow CO to flow into a garage. C Attic vent Generator exhaust can enter through attic vents and the vents for soits, crawl spaces, and ridges or roofs.

Basement windows Basement windows or hatches that permit ventilation to or from the structure’s lower level also allow CO gas to enter the structure.

Furnace intake or exhaust vent Air intakes and furnace exhaust pipes are common entry points for CO gas. F Wall cracks Any cracks in a structure’s walls, including the foundation and mortar, and any gaps around windows, doors, and pipes can let CO in. G Dryer vent Sometimes the exhaust vent for the clothes dryer lets CO gas into the structure.

Airflow restrictions Areas featuring structural corners and heavy vegetation restrict the airflow and collect exhaust gas.

Makeup air system Note: Keep all mechanical and gravity outdoor air intake openings for HVAC supply air systems 10 ft (3,0488 m) horizontally from the generator’s enclosure. Refer to section 401 in the ICC Mechanical Code for details on requirements.

Carbon monoxide detector(s) Note: Installing functioning CO alarms indoors is the only way to recognize CO gas. Common smoke alarms do not detect CO gas and will not alert occupants of its presence. Not for Reproduction14 Part No. 80106286 Revision C Generator PlacementReducing the Risk of Fire Reducing the Risk of Fire To help prevent fires, the generator must be installed a safe distance from all combustible materials. The unit’s engine, alternator, and exhaust system components can become very hot during operation. Reduce the likelihood of a fire by keeping the unit properly ventilated, properly maintained, free of fuel leaks, and away from combustible materials. Also, flammable debris may collect within or outside the generator enclosure and may possibly ignite, causing a fire. Federal and international standards describe the minimum safe clearances around and above the generator’s enclosure. Distance Requirements An owner must maintain minimum clearances around the generator enclosure. These clearances exist primarily for fire prevention, but they also ensure adequate space for maintenance tasks, such as removing the unit’s front and end panels.

Generator Placement Federal and International Standards

LOCATION ITEM EXPLANATION

A Front and end clearance Maintain a 3 ft (.91 m) minimum clearance from the front and ends of the generator. Keep shrubs, bushes, plants, and trees this same minimum distance from the unit and never use vegetation to conceal the unit. B Rear clearance Since fuel and electrical connections occur here, keep 18 inches (45.70 cm) minimum clearance per independent testing laboratory, unless state codes tell you otherwise.

Windows, vents, and openings Keep all operable windows, doors, vents, window wells, or openings in the wall away from the point of the generator. See Protecting the Structure section in this manual. D Existing wall Keep the generator at least 18 inches (457 mm) away from existing walls. E Removable fence Keep removable fences at least 3 ft (.91 m) away from the front of the generator. Removable fences include visual surrounds, fence panels, and temporary barriers without footings. F Overhead clearance Maintain a 5 ft (1.52 m) minimum clearance from all structures, overhangs, and projections on a wall. G (not shown) Maintenance and servicing Allow adequate space to perform routine maintenance, such as servicing the engine and replacing the battery. Never use shrubs, bushes, trees, or plants to conceal the generator. Federal and International Standards Generator installation must strictly adhere to ICC, IFGC, NFPA 37, NFPA 54, NFPA 58, and NFPA 70 standards. National Fire Protection Association (NFPA) 37: This standard addresses the installation and use of stationary combustion engines. Its requirements describe keeping an enclosed generator a specific distance from a structure or wall. This standard also requires that when you locate a generator, you provide adequate space to perform maintenance and repair tasks and space for the maneuvering of first responders. NFPA 37, Section 4.1.4, Engines Located Outdoors: This requirement specifies that engines and their weatherproof housings (if provided) installed outdoors must remain at least 5 ft (1.52 m) from openings in walls and at least 5 ft (1.52 m) from structures with combustible walls. The standard does not require a minimum separation if the following conditions exist:

1. The structure’s adjacent wall has a fire-resistance

rating of at least one hour.

2. Where a fire test involving consumption of the

available combustibles, within the engine or, if provided, its weatherproof housing demonstrates that a fire originating at the engine or its weatherproof housing will not ignite combustible structures. Annex A—Explanatory Material A4.1.4 (2): This requirement means that demonstrating compliance involves conducting a full-scale fire test or by following calculation procedures. This requirement concludes that due to the limited space frequently available for installation of the unit, exception (2) is beneficial for many residential and commercial installations. The manufacturer has contracted with an independent testing laboratory to conduct full-scale fire tests. The ultimate goal of the fire testing was to determine the absolute worst fire scenario within the generator and to calculate the ignition risk of items outside the engine enclosure at specific distances. Note that the enclosure is constructed of non-combustible materials. Outcomes from independent lab tests showed that any fire that started within the generator enclosure would not pose any ignitability risk to nearby combustibles or structures for at least one hour. Not for Reproduction16 Part No. 80106286 Revision C InstallationReducing the Risk of Fire Combining results from these full-scale tests and the requirements of NFPA 37, Sec 4.1.4, the guidelines for installation of the generators previously mentioned change to 18 inches (45.72 cm) from the back side of the generator to a stationary wall or building. To maintain clearance for proper maintenance and airflow, the area above the generator must be at least 5 ft (1.52 m), with a minimum of 3 ft (.91 m) at the front and ends of the enclosure. Keep trees, shrubs, plants, and bushes within these clearance requirements to prevent the obstruction of airflow. Also, note that exhaust fumes flowing from the generator could stifle plant growth. See Figure 3 for details. Other General Location Guidelines

• Place the standby generator in a prepared location that is flat and has provisions for water drainage.• Install the standby generator in a location where sump pump discharge, rain gutter downspouts, roof runo, landscape irrigation, or water sprinklers cannot flood the unit or spray the enclosure and enter any air inlet or outlet openings.• Install the standby generator where it cannot aect or obstruct any services (including covered, concealed, and underground), such as telephone, electric, fuel (natural gas or LPG vapor), irrigation, air conditioning, cable, septic, sewer, well, etc.• Install the standby generator where leaves, grass, snow, and other materials cannot obstruct the air inlet and outlet openings. Construct a windbreak to protect the unit if the area is prone to prevailing winds, blowing, and drifting. INSTALLATION Lifting the Generator WARNING Hazardous Voltage – Contact with power lines could cause electric shock or burns, resulting in death or serious injury.• If lifting or hoisting equipment is used, DO NOT contact any power lines.• DO NOT lift or move the generator without assistance.Proper tools, equipment, and qualified personnel must be used in all phases of handling and moving the generator.

• A licensed professional must perform the installation.

• Install the fuel supply system according to NFPA 37 and other applicable fuel-gas codes.

• Before placing the generator into service, properly purge and leak-test the fuel system lines.

• NO leakage is permitted.

• DO NOT operate the engine if you smell fuel. DO NOT install the supplied flexible fuel line underground or in contact with the ground.

• Keep the entire flexible fuel line visible for periodic inspection. Do not conceal it or run it within any wall, floor, or partition. Never let the line contact these structures. The following information addresses the planning phase of installations for technicians specializing in gaseous fuel systems. Always obey the local applicable fuel-gas codes aecting the installation site. Consult your local fuel supplier or fire marshal with any questions or problems. Not for Reproduction20 Part No. 80106286 Revision C InstallationFuel Installation Plan WARNING Propane and natural gas are extremely flammable and explosive, which could cause burns, fire, or explosion, resulting in death or serious injury.

• The generator features an automatic safety gas fuel shut-o valve.

• DO NOT operate equipment if the shut-o valve is missing or inoperative.

• Liquefied Petroleum (LP) gas is heavier than air and settles in low areas.

• Natural gas is lighter than air and collects in high areas.

• The slightest spark could ignite these fuels and cause an explosion.

• DO NOT light a cigarette and DO NOT smoke. TO THE INSTALLER: Consult with the generator owner(s) and address any technical considerations aecting their installation plans before applying these guidelines. The following general rules apply to piping on gaseous fuel systems:

• The piping material must follow federal and local codes, with rigid mounting and protection against vibration.

• Protect piping from physical damage, especially where it passes through flower and shrub beds and other cultivated areas where damage can occur.

• Install the provided flexible fuel line (B) between the generator fuel inlet port (A) and the rigid piping to prevent excessive stress on the piping material due to thermal expansion and contraction.

• Provide a union (C) or flanged connection downstream to allow for future removal.

• Install a manometer test port (D) for vapor fuels. Use the port to install a manometer and check if the engine receives the proper fuel pressure adequate for operation. See the service center for a digital or analog manometer designed for vapor fuels only (part number 19495). After completing the initial test runs, remove the manometer and plug the port.

• For vapor fuels only: Protect piping from freezing in areas that are prone to the formation of hydrates or ice. When terminating hard piping, use a sediment trap (E) where condensate liquid cannot likely freeze.

• Install a minimum of one accessible, approved manual shut-o valve (F) in the fuel supply line within 6 ft (1.8 m) of the generator.

• Install a manual shut-o valve in the interior of the building.

• Increase strength and flexibility of the piping supports and connections in areas prone to earthquakes, tornados, flood hazards, and unstable ground.

• Ensure that the size of the piping is adequate enough 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 a pipe sealant or joint compound approved for use with natural gas/liquefied petroleum on all threaded fittings to reduce the possibility of leakage. Keep thread sealant out of the gas piping to prevent damage to component parts.

• Properly purge and leak-test piping according to applicable codes and standards. Figure 9 (A) Generator Fuel Inlet (B) Flexible Fuel Line (C) Union Fitting (D) Manometer Test Port (E) Sediment Trap (F) Manual Shut-o Valve Not for ReproductionPart No. 80106286 Revision C

• LHV (Low Heat Value) is the more realistic rating. ** Gross heat value does not consider heat lost in the form of water during combustion. *** Density is given in “Cubic Feet of Gas per Gallon of Liquid.”

Weight is given in “Pounds per Gallon of Liquid.” Fuel Type Consider the type of fuel that your generator uses, as it aects the entire installation process. The system was factory tested and adjusted using natural gas, but it can be converted to use liquefied petroleum vapor. For correct engine function, consider factors that aect each of these fuels, such as the location and the duration of possible utility interruptions. Follow these guidelines when choosing fuel type:

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

• In engines set up to run on propane (liquefied petroleum), only use commercial-grade HD-5 propane. Natural gas or LP engines are certified to operate on natural or liquid propane gas. The emissions control system for this engine is EM (Engine Modifications). Fuel Pressure Both LP vapor and natural gas fuel supply pressure at the generator’s fuel inlet port must be a minimum value at full load with all gas appliances turned on and in operation. Natural Gas must be 3.5-7 inches Water Column (WC). Liquefied Petroleum must be 11-14 inches WC. Ensure that all gas line shut-o valves are OPEN and that adequate fuel pressure is available whenever automatic operation is needed. Not for Reproduction22 Part No. 80106286 Revision C InstallationFuel Installation Plan Power Loss Air density decreases at high altitudes, resulting in less available engine power. Engine power can decrease by 4.8% for each 1000 ft (305 m) above rated altitude of 800 ft (250 m) and by 1.1% for each 10° F (5.6° C) above 77° F (25° C). Adjust the transfer switch of any generator located in an area aected by high altitudes and drops in power. See the Automatic Transfer Switch Manual for details on the process of adjusting for a power decrease. The Gaseous Fuel System Fuel Pipe Sizing An installer commonly uses NFPA 54 and 58 as resources on this topic. The installer must consider the specific gravity of gas, compensate for a nominal amount of restriction from bends and fittings, and refer to federal and local codes for guidance. Fuel Conversion The engine of your home generator system is factory calibrated and set to operate on natural gas, but it can also operate on liquefied petroleum vapor. Units are set to NG at the factory. To convert to either fuel, follow these steps:

Maintenance Servicing the System 15-Amp Fuse Ensure that the fuse is correctly installed before operating the generator. Automatic Operation Sequence The generator’s controller monitors utility voltage. If the utility voltage drops below a preset level, the controller signals the engine to crank and start. When the utility voltage restores above a preset voltage level, the engine receives signals to shut down. The actual system operation is not adjustable and undergoes sequencing by sensors and timers on the controller in the following manner: Utility Voltage Dropout Sensor

• This sensor monitors the utility source voltage.• If the utility source voltage drops below approximately 70% of the nominal supply voltage, the sensor initiates a timer.• The engine cranks and starts once the timer has expired. Utility Voltage Pickup Sensor This sensor monitors the utility voltage. When the utility voltage restores above approximately 80% of the nominal source voltage, a shut-down timer initiates and the engine cools down. Engine Cool-down Timer When the system senses the utility power, the load transfers to the utility source and the engine enters a five-minute cool-down period. Setting the Exercise Timer 1.

Engine Oil The engine is filled with full synthetic oil (API SJ/CF 5W-30). This oil allows for system operation in the widest range of temperature and climate conditions. The manufacturer recommends using Briggs & Stratton® 80028446 SAE 5W-30 full synthetic engine oil. Other full synthetic high-quality detergent oils are acceptable if classified for service SJ or higher. Do not use special additives. Note: An acceptable oil at all temperatures includes full synthetic oil that:

• Meets International Lubricant Specification Advisory Committee (ILSAC) GF-2 standards

• Carries the API certification mark

• Features an API service symbol with “SJ/CF energy conserving” or higher Using full synthetic oil does not alter the required oil change intervals described in the Operation section.

Figure 24 Electronic Governor System The engine electronic governor system oers improved control and increased generator performance compared to mechanically governed systems. The result is a smooth steady-state operation without the “hunting” common to many mechanical governors. The system also reduces speed variations under engine loading and unloading and significantly reduces frequency fluctuation when the engine runs under higher loads. The electronic governor system features a stepper motor (B), stepper motor throttle control linkages (C), and throttle side linkage (A). The controller contains a digital controller that processes engine speed information and sends appropriate commands to the stepper motor to control the position of the engine throttle. Since the electronic governing system controls the engine throttle demand based on generator load, the following service codes and/or conditions could arise from an electronic governing system issue:

• Engine does not start

• Unstable no-load engine control While troubleshooting any of these conditions, use the controller’s actuator test to initiate a verification of the electronic governor system.

Figure 25 Electronic Governing Check The generator has an electronic governing check feature that will turn on the stepper motor and move the throttle linkage clockwise and counterclockwise within the throttle limits. The test will rotate the stepper motor and move the throttle arm between the wide open throttle and dead idle limits for up to ten seconds. This check lets you visually verify whether or not the stepper motor functions correctly and whether or not the control linkages are connected. The engine will not attempt to start during this test. If the stepper motor does not move or if a linkage binds, the generator requires service. If the stepper motor does not move, ensure the stepper motor connector is attached.
