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,NEPA 54,NFPA 58 and NEPA 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.
• Mow 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 5ft.(1,52m)of clearance above the generator,3ft.(.91m)of clearance on sides and
front,and a minimum of 18in,(457mm)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.5in(13mm)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,ail 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 5ft.(1,52m)from openings in walls and at least 5ft.(1,52m)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 materiels 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 18in.(457mm)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.

Compliant With Clause (21
of Section 4.1.4 of 1FPA 37
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,him
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 18in.(457mm)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 Off.(1.22m)with a minimum of 3ft,(.91 m)at the front and ends of the enclosure.This
would include trees,shrubs and vegetation shorter than 12in.(305mm)in height.Vegetation taller than 12in.(305mm)in height must have a
clearance of 60in.(1524mm).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.
®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
supply is not turned off,sparking can occur at the battery posts and cause an explosion.
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 wilt 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.
3.11 CRUSHED STONE OR GRAVEL
• Dig a rectangular area approximately 5in.(127mm)deep and about 6in.(152mm)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 4-5in.(102.127mm)thick and extend 6in. (152mm)beyond the outside of the generator in all directions.
NOTE: If a concrete pad is required,follow all applicable Federal,State or local codes,

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(7-13mm mercury).Required fuel pressure for for liquid propane vapor is
10-12"water column(19-22mm 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 fur-
ther 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.

A DANGER!
Gaseous fuels such as natural gas and liquid propane(LP)gas are highly explosive. Even the slightest spark can ignite such fuels
and cause an explosion.No leakage of fuel is permitted.Natural gas,which is lighter than air,tends to collect in high areas.LP gas
is heavier than air and tends to settle in low areas.
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 1 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 I megajoule and required gas pressures.To calculate BTU or Megajoules:
-- Natural Gas: BTU=Cubic feet/hour x 1000
Megajoules=Cubic meters i 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 2.5ft.(.76m)for every angle or bend in the pipe and add that to the overall pipe distance,

GAS PIPE SIZING IS ONE OF THE MOST CQMMONL Y MADE MISTAKES A eRQPERLY SIZED QAS PIPE IS(Wirt
CAL 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 I 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 flaw rated shut-off near generator per local jurisdiction or code
1$
ZS/DZ 39Vd 313 1dIa1SfQNI DO DV Z6117E8ED98 bT:9T ETDZI0Ef60
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 at the
connection points,so it's important that the line be Installed with as few trends as possible.Configure the sediment trap(if applicable or
required by code)as illustrated.

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.
