Site Planning
Room Size Open frame generators must be protected from the environment while having good ventilation
and cooling. Here are some considerations for planning a generator room or enclosure:
S Never use the Genset room for storage as well. S The room must be large enough to contain the genset and all the accessories, such as
batteries and their charging system, transfer switch and other controls, and elements of the cooling and fuel systems.
S A minimum of 2 feet (preferably 4 feet), must be allowed on the two sides of the engine
for service access.
S On the generator end of the engine, allow a space equal to the length of the generator
(generator length only, not the entire genset).
S At the front of the engine, 4 feet of clearance is preferable. Allow clearance between
hot parts of the system (exhaust) and structural members of the building.
S Certain safety and building codes may require the genset room not to be used to house
any other mechanical or electrical equipment.
General Information 2‐3MN2408
Room Location Often a separate building located on the site away from the main building is the most simple and
cost effective. Major considerations when housing the genset in a separate building are:
S Maintain the building at a satisfactory temperature year round (to meet applicable
codes).
S Assure the genset is not located so far from the emergency loads that reliability is
compromised.
S The floor's load carrying capacity must be checked and must exceed the weight of the
genset and its associated equipment.
S Engine Cooling System
A genset with an engine mounted radiator is the least costly to install; however, the room must be located in a place where sufficient radiator cooling air can be brought into and exhausted from the room.
S Exhaust System
The exhaust system must minimize exhaust restriction. Exhaust restriction must be limited to 3 in. Hg (76 mm Hg) maximum, to ensure proper engine operation. The exhaust system should be as short and have as few bends as possible.
S Room Air
If the genset is cooled with an engine mounted radiator, and sufficient air is brought into and exhausted from the room to satisfy the radiator cooling requirements and the combustion air requirements, the room will not overheat when the genset is running. If a remote mounted radiator or a heat exchanger is used, and adequate air is circulated through the room to keep it at a reasonable temperature, there will be adequate air for combustion.
S Fuel Tanks (Diesel Only)
Locate the fuel storage tank as near the genset as possible. This will minimize the cost of fuel system installation and will maximize fuel system reliability.
S Controls and Transfer Switch
Locate the control switch gear as close to the emergency loads and the genset as practical. This will minimize the chances that a failure of the power line to the emergency load will go undetected. In locating the switchgear, accessibility for service and maintenance must be considered.
S Genset Noise
Internal combustion engines produce noise, so the room should be located away from occupied buildings. In addition the genset room can be treated to reduce noise transmission. In locating the genset room, both engine, fan and exhaust noise must be considered.
If noise within the genset room, or noise transmitted to the surrounding parts of the building are a concern, then the room must be made large enough to allow for installation of noise attenuating walls and noise absorbing walls. Light weight concrete blocks filled with sand or special “sound block” concrete blocks are commonly used. Noise attenuating, tight fitting windows and doors also help reduce noise transmission to the rest of the building. A double-walled room should be considered. Vibration isolators under the genset rails will also reduce the transmission of noise through the floor.
S Code Requirements
Building and safety codes deal with engine location. These requirements are concerned with fire rated walls, a location that minimizes the possibility of damage to the genset and interruption of the emergency system due to storms, foods, fire, vandalism, etc.
Codes often deal with the need to maintain certain temperatures in the genset room and with fuel system location. The most important codes in the USA are the National Fire Protection Association Code Numbers 99 and 110, but local codes must also be observed.
2‐4 General Information MN2408
Foundation Design WARNING: An open bottom stationary engine generator set must be installed over noncombustible
materials and shall be located such that it prevents combustible materials from accumulating under the generator set.
Foundation Checklist
A. Evaluate if a separate, isolated foundation is required for the application. B. Observe local codes on soil bearing capacity freezing and thawing. C. Design the separate foundation for the genset and specify the appropriate concrete mix. D. Determine if the application requires vibration isolators and if so, order as a factory option.
The foundation must be strong enough to support the weight of the genset and its associated equipment, must prevent any deflection of the genset base and absorb vibration produced by the rotating and reciprocating masses.
Setting The Genset On An Existing Concrete Floor Slab
S If an existing floor is used, the floor slab must be strong enough to carry 1.50 times the
genset wet weight (including coolant and oil) to accommodate dynamic loads.
S The actual mounting arrangement (ie., surface area in contact with the floor) will
determine the compressive strength required.
S The genset should be securely fastened to the floor slab with expansion anchors that fit
the mounting holes shown on the genset installation diagram.
S For installations not expected to be permanent, elastomer pad with non-slip surface
placed between the base and the floor will also prevent movement.
S Any floor/slab surface should be as flat as possible to prevent sub-base deflection.
Vibration Isolators
S Mounting to the pad, will result in overall reduced motion on other parts of the genset.
The trade-off is that slightly more vibration is transmitted to the structure.
S A more common practice when mounting to a concrete pad is to use vibration isolators.
The two most common types of vibration isolators are steel spring and elastomer pad. The primary purpose of vibration isolators is to reduce the noise and vibration which would be transmitted from the genset to the foundation or supporting structure.
S A simple and effective method of mounting and applying pad type isolators is to place
non-skidding type isolation pads directly between the sub-base and floor. The number of pads required will be determined by the load bearing capability of the pads and the genset's weight.
Figure 2‐1 Typical Installation of Spring Type Isolator
General Information 2‐5MN2408
S Steel spring isolators are a very effective and commonly used. Steel spring isolators
are typically 95-98% efficient (reduces the transmitted vibration 95-98%) while a pad type can be 75-88% efficient. Spring isolators also level the genset sub-base in the event the foundation pad is not perfectly level.
Spring steel isolators offer the highest level of vibration isolation, however higher levels of vibration (although not detrimental) may be seen on some areas of the genset when mounted on steel springs, due to the (almost) total isolation from the foundation. The base of most steel spring isolators contains a non-skid pad. The base should be mounted to the foundation pad as shown in Figure 2‐1 or as recommended by the isolator manufacturer.
A common practice is to pour a concrete pad directly on top of the floor slab and to mount the genset on this pad. The purpose of the pad is to facilitate cleaning around the genset and to provide a more level base. When using this method, floor strength must support the pad and the genset. The pad should be at least 6in (150mm) thick and extend beyond the genset in all directions 12in (300mm).
Weight Of The Genset
The dry weight of the entire genset is shown on the Generator Set Specification Sheet. The wet weight includes the fluids (coolant and oil). Figure 2‐2 can be used to design the foundation except in critical situations.
Figure 2‐2 Approximate Weight vs. kW Output
2‐6 General Information MN2408
Designing An Isolated Foundation
If the genset cannot be mounted directly on a floor slab, or if it is desirable to isolate it from the floor slab, then a separate foundation slab must be designed.
A massive concrete foundation is not required. Outside dimensions of the foundation should exceed the outside genset dimensions by 12in (300mm). For single genset installation, the foundation weight should be a minimum of 1.50 times the genset wet weight. For multiple genset installation, the foundation weight should be a minimum of 2.0 times the genset wet weight. Figure 2‐3 shows a method to calculate foundation thickness and the soil bearing load of the foundation and generator set. The soil load bearing capacity under the foundation must equal or exceed the load from the foundation and genset. If it does not, then a footing, as shown in Figure 2‐4 must be added to spread the load over a larger area.

Table 2‐1 shows approximate load bearing capacities for various types of soil if the actual load bearing capacity of the soil under the foundation is not known.
Caution: Check the local building codes for load bearing capacity requirements. Caution: If the soil is subject to freezing and thawing, the foundation must be extended below the frost
line. Check the local building codes.
S Reinforce the foundation with No. 8 gauge steel wire mesh placed horizontally on
6in (150mm) centers. As an alternative, use No. 6 re-bars on 12in (300mm) centers horizontally. Minimum cover over the bars should be 3in (76mm).
S Suggested concrete mixture by volume is 1 part cement, 2 parts sand, and 3 parts
aggregate. Maximum slump of 4in (100mm) and a 28-day compressive strength of 3000 psi (20,600 kPa).
S The size of the bolts holding the sub-base to the foundation should be sized to fit the
mounting holes shown on the Installation Diagram.
S Three-inch (76mm) iron pipe sleeves should be placed around the bolts in the
foundation to allow for any mislocation of the bolts after the foundation hardens. “J” or “L” type bolts are recommended for the foundation bolts.
S After the foundation is cured and the genset is located, the sleeves are filled with grout.

A. Exhaust outlets are not located upwind or near any building air intakes. B. Flexible piping section is used at engine exhaust outlet. C. Exhaust piping material is adequate for expected service. D. Exhaust piping sizing is adequate to prevent back pressure. E. Exhaust piping components are insulated as necessary to prevent operator burns and reduce pipe radiant heat losses. F. Pipe sleeves or fire proof materials are used where exhaust pipe passes through building materials as per local and state codes. G. Exhaust pipe includes rain cap or is horizontal.
The purpose of the exhaust system is to safely discharge the engine combustion products into the atmosphere outside the building. A silencer should be installed in the exhaust system to reduce noise levels. Compliance with local noise codes is always required.
Level Of Attenuation
In general, manufacturers offer three grades of silencers: industrial, residential, and critical. In most cases, these grades are comparable from make to make. However, attenuation curves for the silencer should be checked to assure the desired level of silencing is met.
System Placement
By this time, the general genset placement within the room or building has been decided. The routing of the exhaust system should be as direct as possible to the building exterior.
WARNING: Never allow the exhaust outlet to be positioned so that the exhaust gases are directed
towards any openings or air entry routes (doors, windows, vents, etc...) of an occupied building. When discharging the hot exhaust gases out of the building do not direct them towards anything that could catch fire or explode.
For aesthetic reasons, consider exhaust placement in relation to the building. Over a period of time, exhaust gas carbon deposits will tend to accumulate on any nearby wall or structure. Attention must also be given to exhaust noise in selecting placement of the exhaust system.
Multi-Engine Installations Caution: Do not connect multi-engine exhaust systems together. Each engine must have its own
exhaust system for proper operation.
Exhaust gases from an operating engine will migrate back through a non-operating engine and cause a hydraulic lock. This may interfere with starting of the second engine. The migrating gases will also tend to turn the turbos which are not being provided lubrication if the engine is not running. The use of check valves in the exhaust system are discouraged due to their tendency to “stick”.
Exhaust Manifold
There are two exhaust manifold types. Dry type which is standard and the optional water cooled. The dry type is simply exposed to the surrounding air and becomes very hot. Shields, insulating wraps, or other types of guards can be used to limit operator contact with the hot surfaces. This practice is common where engine room size is small, creating cramped conditions.
Water cooled exhaust manifolds are not available on all engine models. This type manifold has passages through which engine coolant is circulated to remove heat from the manifold surface. It also will help protect the operator from contact with the hot manifold surface. This will reduce the amount of heat that is radiated by the engine to the surrounding air by approximately 20%. In addition, this type manifold significantly increases the amount of heat the cooling system must dissipate. Marine and Mining Safety Administration (MSA) codes may require water cooled manifolds in all genset installations. If you are in doubt on your particular application, consult your Baldor Distributor.
Exhaust Gas Restriction
The maximum allowable back pressure, or system restriction, is 3 inches of mercury. If this back pressure is exceeded, the air-fuel ratio is reduced due to incomplete scavenging of the cylinders, fuel economy and power output is reduced, engine life is reduced and exhaust temperatures and smoke levels increase. Any restriction of the exhaust gas reduces horsepower. Take every precaution to reduce restriction. Proper design and installation will provide safe genset operation.
It is essential that all engine exhaust systems by designed with the least possible restriction to exhaust gas flow. This can be calculated through the use of Figure 2‐6, or in the case of simple exhaust systems, the nomograph in Figure 2‐6 may be used.
General Information 2‐9MN2408
Figure 2‐6 Exhaust System Calculations
Exhaust Piping Caution: The weight of the exhaust system must never be imposed on the turbo-charger outlet.
Damage to the turbo-charger and other components may result.
An exhaust system must withstand the vibration and thermal expansion that they are subjected to, yet supported well enough to remain independent of the engine.
The most common method of providing flexibility is with the use of bellows type flexible piping. This piping component allows lateral and linear movement of the piping system without subjecting fixed components to excessive stress. A minimum of 12 inches of flexible connection must be provided at the engine exhaust manifold to allow for thermal expansion and vibration. If the engine is to be mounted on spring type vibration isolators, increase the length to 24 inches. This component can be specified to be provided by your Baldor distributor. Flexible pipe should never be used for pipe bends or to cure misalignment problems.
Exhaust piping systems may be supported by a wide variety of methods to long as the system remains flexible, and capable of withstanding thermal expansion.
The material most commonly used for straight runs and elbows in exhaust systems is Schedule 40 black iron. If hanging weight is a problem, other materials may be used. Galvanized piping should never be used in exhaust system. Where exhaust piping passes through combustible material, exhaust thimbles must be used. See Figure 2‐7.
Figure 2‐7 Exhaust Pipe Thimble Installation
Rain Protection
Moisture entering the engine through an exhaust system can cause extensive damage. Exhaust outlets must have a rain cap or be horizontal to prevent such damage. See Figure 2‐7.

Transfer Switch
Transfer Switch Checklist
A. Locate transfer switch in a clean, dry place, near the emergency load. B. Provide a circuit breaker between the genset and the transfer switch. C. Put a flexible connection between the conduit and genset. D. Observe applicable codes in wiring-in the transfer switch and genset.
The transfer switch connects the genset to the emergency power system. The emergency power system may include several gensets and several transfer switches. Typically, the genset is wired to the emergency power system through a transfer switch as shown in Figure 2‐8.
Figure 2‐8 Typical Emergency power System Installations
Multiple Gensets can be arranged either in parallel or separately connected to dedicated emergency loads. Figure 2‐8 also shows a typical arrangement of two gensets in parallel with transfer switches for loads that have different levels of priority. A typical multiple genset installation is shown for NFPA 110 Level 1 and Level 2 emergency power circuits and a priority control to select the appropriate transfer switch.
Wattmeters should be installed on each genset so load sharing can be checked. The control system should include an automatic paralleling control. Paralleling identical gensets is not difficult, but paralleling dissimilar sets can cause load sharing problems. When designing an installation that includes the paralleling of dissimilar generators, contact your nearby Baldor Distributor.
Transfer Switch Location
The transfer switch location is important and key considerations are:
1. Locate the transfer switch as close to the emergency load as practical to avoid
2. Locate the transfer switch in a clean, dry, well ventilated location, away from excessive

the transfer switch. Baldor Gensets are available with properly sized circuit breaker built into the generator control through 1200 amp breakers. The circuit breaker can be separately mounted. In the case of very large circuit breakers, a separate floor mounted circuit breaker is easier to wire up than a wall mounted breaker.
genset. The flexible sections prevent vibration from damaging the conduit. All power conduits from the genset must contain all three phases.
General Information 2‐11MN2408
6. Conduit, wire, circuit protective device sizes, insulation etc. must conform to applicable local and national codes and regulations.
7. Be certain to seal around conduits that penetrate the walls of the genset room to reduce the amount of noise that is transmitted to the surrounding areas of the building and maintain site fire code rating.
Battery Starting System
This section describes the battery starting system (nominal 12 volt rating of the battery supply) for the engine, battery charger, and precautions to take if the ambient temperature is expected to be below 70 F (20C).
WARNING: If batteries are not mounted in the battery rack supplied with the genset, protect batteries
from vibration and do not locate them near a source of flame or spark. A battery presents a risk of fire and explosion because they generate hydrogen gas. Hydrogen gas is extremely explosive. Never jump start a battery, smoke in the area around the battery or cause any spark to occur in the area around the battery.
Battery Location
Locate batteries as close as possible to the genset to minimize starting circuit resistance, see Figure 2‐9. High starting circuit resistance substantially reduces starting cranking ability. Mount batteries on a level rack away from dirt and liquids. Allow space for servicing (checking water level and level of charge). Cold ambient temperature at the battery location substantially reduces the battery output.
Figure 2‐9 Battery Starting System
Battery Size
The ability to start the engine depends upon battery capacity, ambient temperature and coolant and oil temperatures. The Engine/Generator Set Data Sheet lists minimum recommended battery capacity.
Battery capacities decrease as ambient temperatures decrease so it is important to specify batteries with the appropriate CCA rating at a temperature no higher than the minimum ambient temperature for the application.
2‐12 General Information MN2408
Battery Charger
Battery Cables
An engine mounted alternator charges the batteries during engine operation. Standby gensets should include a solid state battery charger that is connected to utility power so the battery is charged continuously while the genset is not running. The battery charger should be connected to the utility power emergency circuit. The batteries on prime power gensets are charged by the engine mounted alternator, if equipped.
The output of the battery charger or the belt driven alternator must be connected directly to the battery or to the battery terminals on the starter to prevent the electronic governor from acting erratically. Make control connections to the genset control using a conduit with a flexible section at the genset to avoid damage due to genset vibrations.
The wire size (wire gauge) of the cables connecting the starter to the batteries must be large enough to ensure proper voltage at the engine starter motor during cranking. The total cranking circuit resistance includes the resistance of the cables from the starting motor to the battery and the resistance of all relays, solenoids, switches, and connections. The resistance of various sizes of cables is shown in Figure 2‐10. For purposes of calculating cranking circuit resistance to select cable size, the resistance of each connection can be taken as .00001 ohms and the resistance of each relay, solenoid, and switch can be taken as .0002 ohms. Figure 2‐10 illustrates an example of a typical cranking circuit resistance calculation.

Section 3 Receiving & Installation
Receiving & Inspection When you receive your generator, there are several things you should do immediately.
1. Observe the condition of the shipping container and report any damage immediately to the commercial carrier that delivered your system.
2. Verify that the part number of the system you received is the same as the part number listed on your purchase order.
3. If the system is to be stored for several weeks before use, be sure that it is stored in a location that conforms to published storage temperature and humidity specifications.
Lifting the Generator When lift or hoist equipment is used to lift the generator and move it to position, be careful not
to contact overhead wires or other obstacles. Be sure lift or hoist equipment has appropriate tires for the terrain to avoid becoming stuck or tipping over. If the shipping pallet is intact, use a fork lift to move the generator. If the shipping pallet has been removed, use two steel pipes through the “Lift Point” holes to lift the generator. See Figure 3‐1.
Figure 3‐1 Generator Lifting
Height
To lift the generator, always use spreader bars, chains, eyehooks and other hardware that is of sufficient strength to lift at least three times the weight of the generator.
Lift Point

Lift Point
Physical Location The mounting location of the system is important. It should be installed in an area that is
protected from direct harmful gases or liquids, dust, metallic particles, shock and vibration. It should be installed in an outdoor location so the exhaust fumes are vented to the atmosphere.
When the Generator is installed outdoors
The factory installed enclosure is designed to keep out undesirable weather elements while providing cooling and ventilation.
When the Generator is installed in a building it is essential to provide:
1. Adequate control and exhausting of the heated air.
2. An adequate and constant supply of incoming cooling air.
3. Adequate control and discharge of the engine's hot exhaust gases.
4. Adequate ventilation of the building when the engine shuts down.
Receiving & Installation 3‐1MN2408
WARNING: An open bottom stationary engine generator set must be installed over noncombustible
materials and shall be located such that it prevents combustible materials from accumulating under the generator set.
Several other factors should be carefully evaluated when selecting a location for installation:
1. For effective cooling and maintenance, the system should be mounted on a flat, smooth, noncombustible level surface. A concrete pad is ideal and provides a secure installation.
2. Installation should prevent water levels from reaching the generator. Drainage must be adequate to keep concrete pad free from standing water.
3. Installation should prevent obstructions by buildup of leaves, grass, sand, snow, etc. If these items pose a problem, consider building a small fence or other break to protect the unit from accumulation of debris.
4. Installation should place the generator as close as possible to the fuel supply and transfer switch.
5. At least twenty-four (24) inches clearance must be provided on all sides for air flow.
6. Access must be provided to allow the enclosure covers to be opened or removed for service and maintenance.
7. Maximum Ambient temperature is 122F (50C).

Secure the Generator
Six (eight for the GLC125) mounting bolts in the base frame secure the generator to the shipping pallet. Remove these bolts, lift the generator and remove the shipping pallet. Secure the generator to the concrete pad using
3
/8 anchor hardware (not provided) in the base frame mounting holes. See Figure 3‐2. Anchor bolts must be long enough to extend through the generator mounting frame.
Engine Cooling A sufficient flow of clean, cool air is required for combustion and to dissipate the heat produced
by the engine. Approximately 60% of the heat value of the fuel used is given off as heat (cooling air and exhaust).
The air that will cool the engine must be brought in from outside the building. A sufficient air-flow of rate “Cubic Feet per Minute” (CFM) will allow the incoming fresh air to cool the engine. This requires a power ventilation system of sufficient CFM to be located at the highest possible point of the building to exhaust hot air and draw in cool fresh air.
Note: The exhaust fan must not be located where it could easily become blocked by leaves,
snow, water, debris, etc.
It is recommended that the cool air intake have at least three (3) times the cross-sectional area of the power ventilation system. It is also recommended that the cool air intake be located as close as possible to the top of the generator set.
The exhaust fan must be connected to the AC power terminals of the generator set so that when the generator set starts it will provide immediate cooling air flow. The fan will operate until the generator set stops. To test the ventilation system, do the following:
Ventilation Test
1. Place a thermometer as close to the cool air intake of the engine's blower housing as you can without allowing the thermometer to touch any material surface.
2. Place another thermometer outside of the building or compartment in the open air (Keep the thermometer out of direct sunlight or any other heat sources).
3. Run the engine under maximum load for an extended period of time (at least one hour).
4. The temperature difference between the two should not exceed 15 degrees F.
Note that opening any door, window or other opening can upset the air-flow pattern and result in a significant reduction in the cooling air-flow across the generator set. This may result in overheating, fire, or explosion.
Receiving & Installation 3‐3MN2408
Hot Exhaust Gasses WARNING: Exhaust fumes/gases are extremely dangerous and can cause severe illness or death. Never
breath exhaust fumes produced by a running engine. Only run the engine outdoors where ventilation is plentiful. Exhaust gases contain carbon monoxide, a colorless, odorless and extremely dangerous gas that can cause unconsciousness or death. Symptoms of carbon monoxide poisoning include: dizziness, nausea, headaches, sleepiness, vomiting or incoherence. If you or anyone else experiences these symptoms, get out into fresh air immediately. Stop the engine and do not restart the engine until it has been inspected and if necessary repaired or reinstalled in a well ventilated area.
WARNING: Hot exhaust gasses must never be directed toward anything that may catch fire or explode.
It is extremely important to discharge engine exhaust gasses away from the engine and out of the building. If these gasses remain in the cylinder, poor performance or eventual engine damage may result. This condition results from excessive back-pressure, which could be caused by any one or a combination of the following conditions:
1. Exhaust pipe too long or the diameter is too small.
2. Excessive number of sharp bends in the exhaust system.
3. Obstruction in the exhaust system.
Backpressure must not exceed 20” of water column.
The direction of the discharged hot air and hot exhaust gases is important as they have the potential to create brown spots on the lawn or adjacent structures. In extreme cases this extremely hot air could cause dried grass or other debris to ignite.
Exhaust lines should be as short and straight as possible. Long pipe lengths and elbows tend to resist the flow of gases and accumulate carbon deposits. Each pipe fitting and elbow will further restrict the exhaust flow.
Guidelines for Exhaust System
1. If you are using a remote muffler it should be mounted as close to the engine as possible, since it will clog with carbon if it's operating temperature is too low.
2. If you are using a remote muffler a flexible coupling of 12” or more must be installed between the exhaust line and the manifold to absorb the engine's vibration. However, a short, solid section of pipe between 6” and 8” long should be placed between the connection of the manifold and the flexible coupling. This nipple will reduce the possibility of the hot gases burning up the flexible coupling.
3. It is extremely important that you do not allow the hot exhaust gases to re-circulate into the engine's cooling air intake.
4. Water is one by-product of combustion and is present in the exhaust pipes or muffler. This water must be kept from draining back into the engine. This can be done by slanting the horizontal section of the exhaust system piping downward slightly, away from the engine. A water trap consisting of a tee extension with a drain cock should also be provided. This water trap should be located between the flex coupling and the muffler, but as close to the engine as possible on a horizontal section of the exhaust piping.
5. It is also recommended that an exhaust rain cap be used whenever it is possible that rain could get into the system. This will help to prevent corrosion and damage to the exhaust system and engine.
6. The exhaust system is subject to the engine's vibration and it must therefore be solidly secured to reduce mechanical stress and the potential for breakage.
7. The engine's exhaust system is the hottest component of the installation and extreme care and considerations must be given to it.
3‐4 Receiving & Installation MN2408
8. As much of the exhaust piping as possible should be located near the power ventilation exhaust. This will reduce the radiant exhaust heat inside the building.
9. Keep all fuel and its associated piping away from all components of the engine exhaust system.
10. After the exhaust system is installed it should be inspected on a regular basis to assure there are no toxic exhaust gas leaks. In some areas this inspection may be provided by your local public service.
11. A carbon monoxide tester may be installed to detect the presence of the deadly gas during times when you are in the building with the engine running (during testing or maintenance).
WARNING: Never allow the exhaust outlet to be positioned so that the exhaust gases are directed
towards any openings or air entry routes (doors, windows, vents, etc...) of an occupied building. When discharging the hot exhaust gases out of the building do not direct them towards anything that could catch fire or explode.
WARNING: Exhaust fumes/gases are extremely dangerous and can cause severe illness or death. Never

Installation The generator is completely assembled, tested and adjusted at the factory before it is shipped to
you. The procedures presented in this manual are suggestions and it is the responsibility of the Owner/Operator to arrange for these procedures to be performed by licensed contractors according to all applicable codes including local codes for your Municipality/City/County and State. External connections required at the time of installation are:
1. Fuel System.
2. Electrical Connections - power wiring (optional transfer switch) and control wiring.
3. Battery (not included).
4. Ground Connection. After installation, the post installation checks must be performed prior to starting the engine. After these checks have been performed and the system operation is verified to be good, refer to
Section 5 Maintenance for periodic checks that must be performed at scheduled intervals to ensure continued operation with minimal problems.
Fuel Connections
Fuel selection is Natural Gas or LPV (Liquid Propane Vapor). If natural gas supply is used, follow the “Natural Gas Connections” procedure. If LPV supply is used, follow the “LP Vapor Connections” procedure. Table 3‐4 defines the flow rate required for each fuel type.

General Considerations
1. A generator set needs the engine to deliver 2 hp of energy to the alternator for every
1000 watts of electric output power (example: an 8000 watt generator needs the engine to deliver 16 hp of energy to the generator end).
2. An engine needs 10,000 BTU's of fuel energy per horsepower of engine power to
provide a sufficient supply of fuel (example: a 16 Hp engine needs 160,000 BTU's of fuel energy for it to work properly). This fuel must be supplied to the regulator on the generator set at a pressure of 6 oz (11 inches of water column). To achieve this 6 oz. pressure in a L.P. System, you will normally have to reduce the tank pressure by means of a primary regulator or a regulator system of 2 or more regulators.
3. There are 2,516 BTU's in one cubic foot of Propane (LP Fuel).
There are 1,096 BTU's in one cubic foot of Natural Gas.
4. There are 36.39 cubic feet in one gallon of Propane.
There are 57.75 cubic feet in one gallon of Natural Gas.
5. There are 8.58 cubic feet per pound of Propane.
There are 23.56 cubic feet per pound of Natural Gas.
6. When installing the piping for the gaseous fuel supply please refer to the pipe chart in
Tables 3‐5 and 3‐6 to be sure you are using piping of significantly large size to deliver the necessary amount of fuel.
7. If copper tubing is used, it should be “K” or “L” having a minimum wall thickness of
0.032 inches. Black Iron Pipe is recommended but follow building codes for your area.
