fatigue, dizziness, nausea, vomitting, confusion, fainting, siezures or death.
.
1.2.1 GENERAL HAZARDS
• For safety reasons, the manufacturer recommends that this equipment be installed by a Service Dealer or other competent, qualified electrician
or installation technician who is familiar with applicable codes, standards and regulations. The operator also must comply with all such codes,
standards and regulations. Only an Authorized Service Dealer is allowed to perform warranty service on this unit.
• The engine exhaust fumes contain carbon monoxide, which can be DEADLY. This dangerous gas, if breathed in sufficient concentrations, can
cause unconsciousness or even death. Do NOT alter or add to the exhaust system or do anything that might render the system unsafe or in
noncompliance with applicable codes and standards.
• Install a battery-operated carbon monoxide alarm indoors, according to manufacturer’s instructions/recommendations.
• Adequate, unobstructed flow of cooling and ventilating air is critical to correct generator operation. Do not alter the installation or permit even
partial blockage of ventilation provisions, as this can seriously affect safe operation of the generator. The generator MUST be installed and
operated outdoors only.
• Keep hands, feet, clothing, etc., away from drive belts, fans, and other moving or hot parts. Never remove any drive belt or fan guard while the
unit is operating.
• When working on this equipment, remain alert at all times. Never work on the equipment when physically or mentally fatigued.
• Inspect the generator regularly, and contact the nearest Dealer for parts needing repair or replacement.
• Before performing any maintenance on the generator, disconnect its battery cables to prevent accidental start up. Disconnect the cable from the
battery post indicated by a NEGATIVE, NEG or (–) first, then remove the POSITIVE, POS or (+) cable. When reconnecting the cables, connect
the POSITIVE cable first, the NEGATIVE cable last.
• Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and may result in dangerous operating
conditions from leaking exhaust gases, fuel leakage, oil leakage, etc.
3
1.2.2
ELECTRICAL HAZARDS
• All generators covered by this manual produce dangerous electrical voltages and can cause fatal electrical shock. Utility power delivers extremely
high and dangerous voltages to the transfer switch, as does the standby generator when it is in operation. Avoid contact with bare wires,
terminals, connections, etc., while the unit is running. Ensure all appropriate covers, guards and barriers are in place, secured and/or locked
before operating the generator. If work must be done around an operating unit, stand on an insulated, dry surface to reduce shock hazard.
• Do not handle any kind of electrical device while standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRICAL
SHOCK MAY RESULT.
• The National Electrical Code (NEC) requires the frame and external electrically conductive parts of the generator to be connected to an approved
earth ground. Local electrical codes also may require proper grounding of the generator electrical system.
• After installing this home standby electrical system, the generator may crank and start at any time without warning. When this occurs, load circuits
are transferred to the STANDBY (generator) power source. To prevent possible injury if such a start and transfer occur, always set the generator
to the OFF mode, remove the 7.5 Amp fuse from the generator control panel, and disconnect the battery before working on equipment.
• In case of accident caused by electric shock, immediately shut down the source of electrical power. If this is not possible, attempt to free the
victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a nonconducting implement, such as a dry rope or board, to
free the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medical help.
• Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in electric shock, or may get caught in moving
components causing injury.
1.2.3
FIRE HAZARDS
• For fire safety, the generator must be installed and maintained properly. Installation must always comply with applicable codes, standards, laws
and regulations. Adhere strictly to local, state and national electrical and building codes. Comply with regulations the Occupational Safety and
Health Administration (OSHA) has established. Also, ensure that the generator is installed in accordance with the manufacturer’s instructions
and recommendations. Following proper installation, do nothing that might alter a safe installation and render the unit in noncompliance with the
aforementioned codes, standards, laws and regulations.
• Keep a fire extinguisher near the generator at all times. Extinguishers rated “ABC” by the National Fire Protection Association are appropriate for
use on the standby electric system. Keep the extinguisher properly charged and be familiar with its use. Consult the local fire department with any
questions pertaining to fire extinguishers.
1.2.4
EXPLOSION HAZARDS
• Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Ensure that no combustible materials are left in the generator
compartment, or on or near the generator, as FIRE or EXPLOSION may result. Keep the area surrounding the generator clean and free from
debris.
• Gaseous fluids such as natural gas and liquid propane (LP) gas are extremely EXPLOSIVE. Install the fuel supply system according to applicable
fuel-gas codes. Before placing the home standby electric system into service, fuel system lines must be properly purged and leak tested according
to applicable code. After installation, inspect the fuel system periodically for leaks. No leakage is permitted.

Install the generator set, in its protective enclosure, outdoors, where adequate cooling and ventilating air is always available (Figure 1.9). Consider
these factors:
• The installation of the generator must comply strictly with NFPA 37, NFPA 54, NFPA 58 and NFPA 70 standards.
• 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, consider using a windbreak to protect the unit.
• Install the generator on high ground where water levels will not rise and endanger it. It should not operate in or be subjected to standing water.
• Allow sufficient room on all sides of the generator for maintenance and servicing. This unit must be installed in accordance with current applicable
NFPA 37 and NFPA 70 standards, as well as any other federal, state and local codes for minimum distances from other structures. DO NOT install
under wooden decks or structures unless there is at least 5 ft (1.52 m) of clearance above the generator, 3 ft (.91 m) of clearance on sides and
front, and a minimum of 18 in (457 mm) of clearance at the back of the unit.
• Install the unit where rain gutter down spouts, roof run-off, landscape irrigation, water sprinklers or sump pump discharge does not flood the unit or
spray the enclosure, including any air inlet or outlet openings.
• Install the unit where services will not be affected or obstructed, including concealed, underground or covered services such as electrical, fuel,
phone, air conditioning or irrigation. This could affect Warranty Coverage.
• Where strong prevailing winds blow from one direction, face the generator air inlet openings to the prevailing winds.
• Install the generator as close as possible to the fuel supply to reduce the length of piping. REMEMBER THAT LAWS OR CODES MAY
REGULATE THE DISTANCE AND LOCATION.
• Install the generator as close as possible to the transfer switch. REMEMBER THAT LAWS OR CODES MAY REGULATE THE DISTANCE AND
LOCATION.
• The generator must be installed on a level surface. The generator must be level within a 0.5 in (13 mm) all around.
• The generator is typically placed on pea gravel, crushed stone or a concrete pad. Check local codes to see what type is required. If a concrete
pad is required, all federal, state and local codes should be followed.
3.1.1
INSTALLATION GUIDELINES FOR STATIONARY AIR-COOLED 8, 11, 13, 14, 15, 16, 17 AND 20 KW GENERATORS
The National Fire Protection Association has a standard for the installation and use of stationary combustion engines. That standard is NFPA 37, its
requirements limit the spacing of an enclosed generator set from a structure or wall (Figure 1.10).
NFPA 37, Section 4.1.4, Engines Located Outdoors: Engines, and their weatherproof housings if provided, that are installed outdoors shall be
located at least 5 ft (1.52 m) from openings in walls and at least 5 ft (1.52 m) from structures having combustible walls. A minimum separation shall
not be required where either of the following conditions exist:
1. The adjacent wall of the structure has a fire resistance rating of at least 1 hour.
2. The weatherproof enclosure is constructed of noncombustible materials and it has been demonstrated that a fire within the enclosure will not
ignite combustible materials outside the enclosure.
Annex A — Explanatory Material
A4.1.4 (2) Means of demonstrating compliance are by means of full scale fire test or by calculation procedures.
Because of the limited spaces that are frequently available for installation, it has become apparent that exception (2) would be beneficial for many
residential and commercial installations. With that in mind, the manufacturer contracted with an independent testing laboratory to run full scale fire
tests to assure that the enclosure will not ignite combustible materials outside the enclosure.
NOTE: Southwest Research Institute tesing approves 18 in (457 mm) installation minimum from structure. Southwest Research is a
nationally recognized third party testing and listing agency.
The criteria was to determine the worst case fire scenario within the generator and to determine the ignitability of items outside the engine enclosure
at various distances. The enclosure is constructed of non-combustible materials, and the results and conclusions from the independent testing lab
indicated that any fire within the generator enclosure would not pose any ignition risk to nearby combustibles or structures, with or without fire service
personnel response.
11
Figure 3.2 — Southwest Research Institute Decal (located inside the generator, next to the generator’s data decal)
http://www.swri.org/4org/d01/fire/listlab/listprod/director.htm
Based on this testing and the requirements of NFPA 37, Sec 4.1.4, the guidelines for installation of the generators listed above are
changed to 18 in (457 mm) from the back side of the generator to a stationary wall or building. For adequate maintenance and airflow
clearance, the area above the generator should be at least 5 ft (1.52 m) with a minimum of 3 ft (.91 m) at the front and ends of the enclosure. This
would include trees, bushes and shrubs. Vegetation not in compliance with these clearance parameters could obstruct air flow. In addition, exhaust
fumes from the generator could inhibit plant growth. See Figure 3.1 and the installation drawing within the owner’s manual for details.
Generator exhaust contains DEADLY carbon monoxide gas. This dangerous gas can cause unconsciousness or death. Do not place the unit near
windows, doors, fresh air intakes (furnaces, etc.) or any openings in the building or structure, including windows and doors of an attached garage.
supply is not turned off, sparking can occur at the battery posts and cause an explosion.
If the generator is not set to the OFF mode, it can crank and start as soon as the battery cables are connected. If the utility power
3.2 SITE PREPARATION
• Locate the mounting area as close as possible to the transfer switch and fuel supply.
• Leave adequate room around the area for service access (check local code), and place high enough to keep rising water from reaching the
generator.
• Choose an open space that will provide adequate and unobstructed airflow.
• Place the unit so air vents won’t become clogged with leaves, grass, snow or debris. Make sure exhaust fumes will not enter the building through
eaves, windows, ventilation fans or other air intakes (see the “Site Selection” section).
• Select the type of base, gravel or concrete, as desired or as required by local laws or codes. Verify your local requirements before selecting.
3.2.1
CRUSHED STONE OR GRAVEL
• Dig a rectangular area approximately 5 in (127 mm) deep and about 6 in (152 mm) longer and wider than the footprint of the generator. Cover with
polyurethane film, if desired, and fill with pea gravel or crushed stone. Compact and level the stone. A concrete pad can be poured if desired or
required. The pad should be 4-5 in (102-127 mm) thick and extend 6 in (152 mm) beyond the outside of the generator in all directions.

Generator Placement
4.1 GENERATOR PLACEMENT
With the Site Selection and Preparation performed, proceed with placement and installation of the generator itself.
All of the air-cooled generators come with a composite pad. The composite pad elevates the generator and helps prevent water from pooling around
the bottom of the generator (Figure 3.1). You can place the generator with a composite pad on 4 in (102 mm) of pea gravel that is compacted or on a
concrete pad. Check local codes to see what type of site base is required. If a concrete pad is required, all federal, state and local codes should be
followed. Place the generator on its mounting pad and position correctly as per the dimensional information given in Section 2.
NOTE: Generator must be level within 0.5 in (13 mm).
13
Figure 4.1 — Composite pad
When mounting the generator to concrete, there are four mounting holes available for securing the generator, if codes require (two holes inside the
front of the generator compartment and two holes in the back). See Figure 3.2.

5.2 FUEL REQUIREMENTS AND RECOMMENDATIONS
With LP gas, use only the vapor withdrawal system. This type of system uses the vapors formed above the liquid fuel in the storage tank.
The engine has been fitted with a fuel carburetion system that meets the specifications of the 1997 California Air Resources Board for tamper-proof
dual fuel systems. The unit will run on natural gas or LP gas, but it has been factory set to run on natural gas. Should the primary fuel need to be
changed to LP gas, the fuel system needs to be reconfigured. See the Fuel Conversion section for instructions on converting the fuel system.
Recommended fuels should have a Btu content of at least 1,000 Btus per cubic foot (37.26 megajoules per cubic meter) for natural gas; or at least
2,500 Btus per cubic foot (93.15 megajoules per cubic meter) for LP gas. Ask the fuel supplier for the Btu content of the fuel.
Required fuel pressure for natural gas is 3.5-7” water column (7-13 mm mercury). Required fuel pressure for for liquid propane vapor is
10-12” water column (19-22 mm mercury). The primary regulator for the propane supply is NOT INCLUDED with the generator.
NOTE: All pipe sizing, construction and layout must comply with NFPA 54 for natural gas applications and NFPA 58 for liquid propane
applications. Once the generator is installed, verify that the fuel pressure NEVER drops below it’s required fuel pressure rating. For further information regarding NFPA requirements refer to their website at www.nfpa.org.
Prior to installation of the generator, the installer should consult local fuel suppliers or the fire marshal to check codes and regulations for proper
installation. Local codes will mandate correct routing of gaseous fuel line piping around gardens, shrubs and other landscaping to prevent any
damage.
Special considerations should be given when installing the unit where local conditions include flooding, tornados, hurricanes, earthquakes and
unstable ground for the flexibility and strength of piping and their connections.
Use an approved pipe sealant or joint compound on all threaded fittings.
All installed gaseous fuel piping must be purged and leak tested prior to initial start-up in accordance with local codes, standards and regulations.
16
5.3 FUEL CONSUMPTION
NOTE: Required fuel pressure for natural gas is 3.5-7 in water column (7-13 mm mercury). The required fuel pressure for LP Vapor is 10-12
in water column (19-22 mm mercury).
These are approximate values, use the appropriate spec sheet or owner’s manual for specific values.

and
is heavier than air and tends to settle in low areas.
Gaseous fuels such as natural gas and liquid propane (LP) gas are highly explosive. Even the slightest spark can ignite such fuels

NOTE: A minimum of one approved full flow manual shut-off valve must be installed in the gaseous fuel supply line. The valve must be
easily accessible. Local codes determine the proper location.
NOTE: THE GAS SUPPLY AND PIPE MUST BE SIZED AT 100% LOAD BTU / MEGAJOULE RATING.
5.4 FUEL LINE SIZING
• First, determine what size pipe is required. Refer to NFPA 54 for NG or NFPA 58 for LP for further information.
• Always refer to the owner’s manual for the proper BTU / megajoule and required gas pressures. To calculate BTU or Megajoules:
– Natural Gas: BTU=Cubic feet / hour x 1000
Megajoules=Cubic meters / hour x 37.26
– Liquid Propane Vapor: BTU=Cubic feet / hour x 2500
Megajoules=Cubic meters / hour x 93.15
• Start by measuring the distance from the generator to the gas source. The generator should be plumbed directly from the source, not off the end
of an existing system.
• When measuring the pipe length, add 2.5 ft (.76 m) for every angle or bend in the pipe and add that to the overall pipe distance.

GAS INSTALLATION SUMMARY
GAS PIPE SIZING IS ONE OF THE MOST COMMONLY MADE MISTAKES. A PROPERLY SIZED GAS PIPE IS CRITICAL TO THE PROPER OPERATION OF THE GENERATOR. THE GENERATOR INLET SIZE HAS NO BEARING ON
THE PROPER GAS PIPE SIZE.
NOTE: THE GAS SUPPLY AND PIPE MUST BE SIZED AT 100% LOAD BTU / MEGAJOULE RATING.
5.5 INSTALLING & CONNECTING GAS LINES
1. Both natural gas and LP Vapor are highly volatile substances, so strict adherence to all safety procedures, codes, standards and
regulations is essential.
Gas line connections should be made by a certified plumber familiar with local codes. Always use AGA-approved gas pipe and a quality
pipe sealant or joint compound.
Verify the capacity of the natural gas meter or the LP tank in regards to providing sufficient fuel for both the generator and other operating
appliances.
• Fuel Regulator installed per laws or regulator manufacturer’s specifications
• AGA approved gas pipe
• Flexible fuel line
– Do not bend!!!
– Do not attach directly to generator
– Check all connections for leaks
• Sediment trap near generator (if applicable or required by code)
• Full flow rated shut-off near generator per local jurisdiction or code
18
2. Most applications will require an external manual full flow shutoff valve on the fuel line.
Figure 5.2 — Full Flow Shutoff Valve
3. When connecting the gas line to the generator, use the provided section of UL Listed or AGA-approved flexible fuel line in accordance with
local regulations. The purpose of the flexible fuel line is to ensure that vibration from the generator does not cause a gas leak at one of the
connection points, so it’s important that the line be installed with as few bends as possible. Configure the sediment trap (if applicable or
required by code) as illustrated.
SEDIMENT TRAP
Figure 5.3 — Sediment Trap
Figure 5.4 — Incorrect Routing of Flexible Hose
19
4. Never bend the flexible fuel line to avoid using an elbow. Bending the flexible line decreases its ability to absorb vibrations and defeats its
purpose, as well as constricts the actual fuel flow. See Figure 5.5.
5. Check for leaks by spraying all connection points with a soap solution made of dishwashing soap and water. You should not see the solution be
“blown away” or form “bubbles”. Next, check the gas pressure at the regulator in the generator by following these steps.
– Close gas supply valve.
– Remove the top gas pressure test port from the regulator (see Figure 5.6) and install the gas pressure tester (manometer).
– Open the gas supply valve and ensure that the pressure is within the specified values.
NOTE: See owner’s manual or spec sheet for proper fuel pressure specifications. If the gas pressure is not within specifications, contact
the local gas supplier.
4) Close gas valve when completed.

NOTE: When sizing a secondary regulator for LP or high pressure natural gas applications be sure to note the maximum individual load
capabilities which will be lower than total capacity. This could impact generator starting performance if sized too small.
NOTE: It is not recommended to reduce the fuel pipe size exiting the secondary regulator unless necessary to accommodate the ½” or ¾”
flexible fuel line that is shipped with the generator. This may potentially cause starting or performance issues.

7.2 GENERATOR ACTIVATION
When battery power is applied to the generator during the installation process, the controller will light up. However, the generator still needs to be
activated before it will automatically run in the event of a power outage.
Activating the generator is a simple, one-time process that is guided by the controller screen prompts. Once the product is activated, the
controller screen will not prompt you to activate again, even if you disconnect the generator battery.
After obtaining your activation code, please complete the following steps at the generator’s control panel in the Activation Chart.
Upon first power up of the generator, the display interface will begin an installation wizard. The installation wizard will prompt the user to set the
minimum settings to operate the generator. These settings are: Current Date/Time and Exercise Day/Time. The maintenance intervals will be
initialized when the exercise time is entered.
The exercise settings can be changed at any time via the “EDIT” menu.
If the 12 volt battery is disconnected or the fuse removed, the installation wizard will operate upon power restoration. The only difference is the
display will only prompt the customer for the current Time and Date.
7.2.1
SETTING THE EXERCISE TIMER
This generator is equipped with an exercise timer. Once it is set, the generator will start and exercise every seven days, on the day of the week and
at the time of day specified. During this exercise period, the unit runs for approximately 12 minutes and then shuts down. Transfer of loads to the
generator output does not occur during the exercise cycle unless utility power is lost.
IF THE INSTALLER TESTS THE GENERATOR PRIOR TO INSTALLATION, PRESS THE “ENTER” BUTTON TO SKIP SETTING UP THE
EXERCISE TIMER.
17 and 20 kW units can run at 2,400 rpm while exercising. While providing the necessary periodic exercise operation, the lower rpm also reduces
fuel consumption, engine wear and noise.
NOTE: The exerciser will operate only when the generator is placed in the AUTO mode and will not work unless this procedure is performed. The current date/time will need to be reset every time the 12 volt battery is disconnected and then reconnected, and/or when the
fuse is removed.
7.3 BEFORE INITIAL START-UP
NOTE: These units have been run and tested at the factory prior to being shipped and do not require any type of break-in.
‹Never operate the engine with the oil level below the “Add” mark on the dipstick. Doing this could damage the engine.
NOTE: This unit comes filled with 30 weight organic oil from the factory. Check the oil level and add the appropriate viscosity and amount
if necessary.

7.3.1 Installation Assistant
Interconnect System Self Test Feature (follow the on-screen prompts)
Upon power up, this controller will go through a system self test which will check for the presence of utility voltage on the DC circuits. This is done to
prevent damage if the installer mistakenly connects AC utility power sense wires into the DC terminal block. If utility voltage is detected, the controller
will display a warning message and lock out the generator, preventing damage to the controller. Power to the controller must be removed to clear this
warning.
Utility voltage must be turned on and present at the N1 and N2 terminals inside the generator control panel for this test to be performed and pass.
