• Make sure that the engine is allowed to cool thoroughly before performing maintenance or operation tasks.

• Clean the exhaust pipe thoroughly.

1.12 The Hazards of Carbon Monoxide

Carbon monoxide (CO) is an odorless, colorless, tasteless and non-irritating gas. You cannot see it or smell it. Red blood cells, however, have a greater affinity for CO than for oxygen. Therefore, exposure even to low levels of CO for a prolonged period can lead to asphyxiation (lack of oxygen) resulting in death. Mild effects of CO poisoning include eye irritation, dizziness, headaches, fatigue and the inability to think clearly. More extreme symptoms include vomiting, seizures and collapse.

Engine-driven generator sets produce harmful levels of carbon monoxide that can injure or kill you.

Special Risks of CO near the Home

WARNING

Toxic Gases Carbon monoxide (CO) gas can cause nausea, fainting, or death. Residents

can be exposed to lethal levels of CO when the generator set is running. Depending on air temperature and wind, CO can accumulate in or near the home.

To protect yourself and others from the dangers of CO poisoning, it is recommended that reliable, approved, and operable CO detector alarms are installed in proper locations in the home as specified by their manufacturer.

Protecting Yourself from CO Poisoning

• Locate the generator set in an area where there are no windows, doors, or other access points into the home.

• Make sure all CO detectors are installed and working properly.

• Pay attention for signs of CO poisoning.

• Check the exhaust system for corrosion, obstruction, and leaks every time you start the generator set and every eight hours when you run it continuously.

FIGURE 6. TYPICAL NATURAL GAS INSTALLATION

Natural Gas Supply Line Size

The natural gas supply meter may need to be exchanged for a higher capacity meter to supply the additional gas consumed by the generator set.

Use the total load requirement of the generator set to determine the size of the fuel supply pipe. Use the tables and charts in the Fuel Line Selection appendix to determine the correct pipe size.

An older site might require upgrading and repair of the gas supply system. Schedule an upgrade or repair to minimize power and gas supply interruptions.

Make sure the full load fuel supply pressure at the inlet to the generator fuel shutoff valves matches the requirements in the Model Specifications section.

Propane Fuel System

Propane vapor can be used as a primary fuel source or as a backup fuel source for the generator sets with two independent fuel sources connected to the generator set.

4 Secondary Regulator

WARNING

Fuel leaks can lead to explosive accumulations of gas. Propane sinks in air and can accumulate inside housings, basements, and other below-grade spaces. Prevent gas leaks and the accumulation of gaseous fuel in the event of a leak.

Page 40

4. Installation 8-2017

NOTICE

NFPA Standard No. 58 requires all persons handling and operating propane to be trained in proper handling and operating procedures.

The required components in a propane vapor fuel system are as follows:

Component Description

Propane Tank Make sure to identify and use the correct tank size based on fuel flow

requirements and the lowest average temperature for your region. If the tank is sized incorrectly, the generator set could run out of fuel. Refer to the Fuel Line Selection appendix.

Shutoff Valve Useful during installation or in the event of a leak (may be required to

meet local codes).

Primary Regulator Located at the tank outlet, the primary regulator reduces the tank

pressure to the working pressure in the fuel supply line. Primary and secondary regulators must be properly matched for a safe and functional system. Consult with your propane supplier to ensure that the regulators are properly sized.

Secondary Regulator

Located near the generator set, the secondary regulator reduces the higher line pressure to a working pressure that matches the requirements in the Model Specifications section. Higher pressure before the secondary regulator is necessary to ensure that there is enough fuel available at the secondary regulator for a fully loaded generator set.

Fuel Line Connects to the fuel supply. It must be sized properly using the propane

fuel line sizing charts (refer to the Fuel Line Selection appendix). Installation must comply with all national, state, and local codes.

Propane Fuel Requirements

Propane presents the hazard of fire or explosion that can cause severe personal injury or death. Do not permit any flame, spark, arc-producing equipment, switch, pilot light, cigarette, or other ignition source near the fuel system. Keep an ABC type fire extinguisher nearby.

Fuel leaks can lead to explosive accumulations of gas. Propane sinks in air and can accumulate inside housings, basements and other below-grade spaces. Prevent gas leaks and the accumulation of gaseous fuel in the event of a leak.

Use clean, fresh HD-5 grade propane or equivalent product consisting of at least 90% propane.

5 Propane Tank

WARNING

NOTICE

NFPA Standard No. 58 requires all persons handling and operating propane to be trained in proper handling and operating procedures.

Page 42

4. Installation 8-2017

NOTICE

Commercial propane may contain more than 2.5% butane, which can result in poor fuel vaporization and low tank pressure, resulting in poor engine starting and operation in below 32 °F (O °C) temperatures.

Propane Tank Size

When propane is used, size the tank correctly to ensure successful generator set operation.

Considerations when figuring the proper propane tank size:

• Temperature is a critical factor that affects the size of the tank. ◦ Ambient temperatures can affect how quickly liquid is converted to

gas.

◦ Generator set fuel consumption is the same regardless of the

surrounding temperatures.

◦ Colder weather climates require larger fuel tanks. Larger tanks have

greater surface area, allowing more liquid propane to vaporize and maintain the required fuel rate.

◦ Propane is stored as liquid. Keep the fuel tank at least 50% full to

operate properly. Fuel tanks that are less than 50% full may not have the capacity to vaporize enough propane to operate the generator set and other LP appliances.

• Propane tanks are sized by their internal volume in gallons, not the

amount of fuel they can hold (which is less).

• Propane tanks are generally filled to only 80% of their capacity.

Therefore, a 500-gallon (1892 L) tank results in 400-gallon (1514 L) tank capacity.

• Low ambient temperatures affect the amount of fuel available from the

propane tank.

• Approximately 60% of the fuel (in gallons) filled in the tank can be

effectively used. Therefore, a 500-gallon (1892 L) tank results in 240gallon (908 L) usable capacity.

To assist in the proper installation of the propane tank, follow the guidelines below.

• Consult your tank and propane supplier for assistance in all aspects of

determining tank size, selection of components and installation requirements.

• Fit the propane tanks with a pressure reducing regulator before

connection to the generator set to prevent fuel system damage.

• Locate the propane tanks and all other fuel system components at least

10 feet (3 meters) from any source of combustion (including the generator set). The fuel supplier or local code may require a larger distance between the tank and source of combustion.

Page 43

4. Installation8-2017

• Install the propane tanks according to all national and local codes and

standards, and as required by the fuel tank and fuel supplier.

Refer to the Fuel Line Selection appendix for propane figures and tables.

Propane Vapor Fuel Supply Line Size and Pressure

Fuel line size depends on the amount of fuel needed to run the generator set at full load at the distance the fuel must be moved.

To correctly size the fuel pipe, you must also take other loads operated from the fuel supply line into consideration, such as space heating and water heating equipment.

Use the total fuel requirement of the generator set and other connected appliances to determine the size of the fuel supply pipe. Use the tables and charts in the Fuel Line Selection appendix to determine the correct pipe size.

See the Model Specifications section for fuel system specifications, including fuel consumption and required fuel system pressure at the generator set.

See the Propane Fuel System section for a typical propane vapor installation. See the Fuel Line Selection appendix for fuel capacity at given distances and

pipe size.

NOTICE

Make sure the fuel supply pressure at the inlet of the generator set fuel regulator (at service port) matches the requirements in the Model Specifications section.

Testing the Fuel System for Leaks

After assembly and before initial operation, all of the fuel system components must be tested and proven free of any leaks.

WARNING

Fuel presents the hazard of explosion or fire which can result in severe personal injury or death. Do not use an open flame to check for leaks. Do not smoke or allow any flame, spark, pilot light, arc-producing equipment, switch or other ignition sources around fuel or fuel components. Keep multi-type ABC fire extinguishers close by.

NOTICE

Follow any local codes and standards, as they may require a different method or documentation of a leak test.

Perform the following fuel piping system leak check:

1. After assembly and before initial operation of generator set, test all fuel system components as required per the National Fuel Gas Code (NFPA 54).

2. The National Fuel Gas Code requires that the generator set be isolated from the piping system by disconnecting it and capping the outlet prior to test. The test pressure required is the greater of 1.5 times the supply pressure or 3 psi (20.7 kPa) minimum.

3. After successfully completing the previous step, connect the generator set to the fuel piping system.

4. To verify that all connections from the fuel piping system to the generator set are free of leaks, conduct a bubble test using an approved leak detection solution (or equivalent method) with the system pressure of 0.8 to 1.0 psi (5.5 to

7.0 kPa).

5. Spray the bubble solution on all of the joints.

6. Inspect all of the joints and monitor the line pressure. If bubbles appear, there is a leak.

7. If any leaks are found, repair the joint or replace components as needed.

8. Verify the leak has been fixed.

NOTICE

The leak detection solution (that is, bubble solution) must be non-corrosive and be free of ammonia and chlorine.

General

Generator set wattage capacity is sufficient to handle maximum anticipated load. At least 5 feet of clearance to combustible materials is provided. At least 3 feet of

clearance is provided around the entire generator set for service and ventilation. The generator set is located in an area not subject to flooding. All installers have read and are familiar with the Generator Set Installation manual and

the Health and Safety manual. All installers have been thoroughly briefed on preventive maintenance procedures. All installers have read and understand all important safety instructions.

Generator Set Support

The floor, roof or earth on which the generator set rests is strong enough and will not allow shifting or movement. Local codes for soil bearing capacity were followed.

5. Startup and Configuration8-2017

The generator set is properly supported and secured to an approved base. The supporting base is of non-combustible material and extends 6 inches all around

the generator set.

Fuel System

Verify that the generator set is configured to the fuel being used. (See the Fuel Selection and Fuel System Connection section.)

Fuel line size has been verified for generator set fuel consumption and pressure. Approved flexible fuel line is installed between main fuel supply and the generator

set’s fuel system near the generator set Fuel lines are properly installed, supported and protected against damage. Fuel supply shutoff valves are installed to turn off fuel flow in case of leaks. No leaks are found in fuel supply line as a result of leak testing fuel systems. The inside of all fuel supply lines is free of contaminants. Fuel pressure is at 6-13 inches of water column (1.5 - 3.2 kPa) under any condition. Fuel pressure maintains at least 6 inches water column (1.5 kPa) when the generator

set is at rated load. The installation is compliant with all state and local codes and regulations.

AC and DC Wiring

Wire sizes, wire types, insulation, conduits and connection methods all meet applicable codes.

Page 72

5. Startup and Configuration 8-2017

Tick Item

AC and DC wires are separated in their own conduit to prevent electrical induction. All load, line and generator connections are well made and correct.

Generator Set Pre-Start

A safety check was performed just before starting. The generator set engine is properly serviced with oil and coolant. The battery is properly installed, serviced and charged. The battery charger and engine coolant heater are connected and operational, if

applicable. All generator set covers and safety shields are installed correctly. The fuel supply is turned on. All fuel shutoff valves are operational. The date and time have been set in the generator set control. The generator set operating mode has been selected.

5.7 Startup

Automated Machinery Accidental or remote starting of the generator set can cause severe personal

injury or death. Isolate all auxiliary supplies and use an insulated wrench to disconnect the

starting battery cables, negative (–) cable first.

After verifying that the installation was completed correctly, start and test the system. Make sure to connect the battery cables to the battery with the positive (+) cable first.

Read through the Operator Manual and perform the maintenance and pre-start checks as instructed.

The following information applies to C70 N6, C80 N6, and C100 N6 generator set models only: Adaptive learn is an engine ECM function that allows the generator set

to "learn" its environment. There are small differences in the performance of each engine and fuel system component, so the ECM uses inputs from the engine sensors to adjust running conditions to operate more consistently for each individual generator set. After installation is complete and while testing the overall system function, the generator set must be run with no active faults under load (that is, transfer switch connected to maximum customer load available) until the engine temperature reaches 80 °C (175 °F) to allow the adaptive learn function to initialize.

WARNING

Page 73

5. Startup and Configuration8-2017

A.0 Fuel System Pipe Sizing Introduction

Incorrect fuel line size may cause the generator set to not run or provide full power output.

Tables are included in this section to help calculate pipe sizing for natural gas and propane vapor withdrawal under specified conditions. Consult NFPA 54 or other applicable codes for other operating conditions or other fuel system installation requirements.

Refer to the Engineering Application Manual T-030: Liquid Cooled Generator Sets manual (A040S369) for more information.

To determine the optimal fuel line size, the following information is needed:

TABLE 20. REQUIRED INFORMATION FOR DETERMINING FUEL

LINE SIZE

Category Description

Fuel Flow Requirements for the Generator Set

Fuel Source (Natural Gas or Propane Vapor)

Fuel Line Length (Including Fittings)

Fuel Line Type (e.g., Copper Tubing or Iron Pipe)

NFPA 54 has selection tables for other approved fuel lines. Verify with the authorities having jurisdiction the allowed fuel line type for the generator set installation.

Fuel flow requirements have a large impact on fuel line size.

Fuel sources can affect fuel line size. Natural gas installations generally require a higher fuel flow rate compared to propane vapor installations, since propane has a higher energy content.

As fuel line lengths increase, they may require larger diameter fuel lines. Be sure to consider the equivalent length of all of the fittings (elbows, tees, valves) in the installation in addition to the straight pipe length.

Most fuel line types are iron pipe or copper tubing. Be sure to use the sizing chart for the fuel line type when sizing the fuel line.

NOTICE

Sizing of gas piping for proper fuel delivery, both flow and pressure, can become quite complex. A simplified method is to convert all fittings, valves, etc. to equivalent lengths of pipe in the diameter(s) being considered. The total equivalent length can then be related to flow capacity. Equivalent lengths of pipe fittings and valves can be found in the table below.

The remaining tables in this section show maximum gas capacity for equivalent lengths of various pipe sizes.

Here are some basic but very important steps that all installers must follow to make sure that fuel lines are sized correctly:

1. Verify adequate fuel flow, quality, and pressure available from the natural gas utility connection or the propane system.

2. Obtain the maximum fuel consumption requirements at full load for the specific generator set from the Model Specifications section and for all gas appliances attached to the pipe system.

3. Make a list of all the fittings and valves in the proposed system used in this generator set installation.

4. Determine the equivalent length of all fuel line fittings (elbows, tees, and valves). (See the NFPA Pipe Fittings table in this appendix to determine the equivalent lengths for all fuel line fittings.)

5. Add the equivalent length of the fuel line fittings to the lengths of straight pipe to determine the total equivalent length of the system.

6. Choose the applicable table in this appendix based on the fuel type (natural gas, propane vapor or liquid propane) and fuel line material.

7. Determine the fuel line size at full load:

a. Locate the equivalent length of pipe (or next larger equivalent

length) in the left hand column.

b. Move across the row to where the maximum flow capacity

number is as large or larger than the maximum fuel consumption.

c. Move to the top of that column to where the minimum nominal

pipe size or tubing size required for the system as designed is shown.
