Section 1 — General Information

1.6SYSTEM SET LED

The “System Set” LED is lit when all of the following conditions are true:

1.The AUTO/OFF/MANUAL switch is set to the AUTO position.

2.The UTILITY voltage being supplied to the unit is being sensed by the PCB. If the UTILITY sense voltage is not connected to the unit or if it is below 168 volts AC, then the System Set light will flash rapidly. This indicates that if the AUTO/OFF/MANUAL switch is placed in the Auto position , the generator will start.

3.The “Not In Auto” dip switch is set to the OFF position on the control board.

4.No alarms are present, for example, low oil pres- sure, high temperature, etc.

1.7FUEL 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.

Air-cooled 8.5 kW Generator

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.

1.9RECONFIGURING THE

FUEL SYSTEM

To reconfigure the fuel system from NG to LP, follow these steps:

NOTE:

The primary regulator for the propane supply is NOT INCLUDED with the generator. A fuel pres- sure of 11 to 14 inches of water column (0.4 to 0.5 psi) to the fuel inlet of the generator MUST BE SUPPLIED.

1.Turn off the gas supply. (if connected)

2.Open the roof and remove the door.

3.Remove the battery. (if installed)

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 Section 1.9 for instructions on reconfiguration of the fuel system.

Recommended fuels should have a Btu content of at least 1,000 Btus per cubic foot for natural gas; or at least 2,520 Btus per cubic foot for LP gas. Ask the fuel supplier for the Btu content of the fuel.

Required fuel pressure for natural gas is 5 inches to 7 inches water colum (0.18 to 0.25 psi); and for liquid propane, 11 inches to 14 inches of water column (0.4 to 0.5 psi).

NOTE:

4.Remove the engine air in baffle located on the left- hand side of the battery compartment. Two M6 screws are located on top of the baffle and two M6 screws are located on the inside of the baffle towards the back.

5.Remove the small hose clamp and hose from the fuel regulator. It may be necessary to pry the hose off of the brass fitting using a screwdriver to gen- tly lift up the hose edge.

6.Remove the small brass hose fitting from the reg- ulator casting.

7.Place the small fuel jet, thread side first, into the threaded hole originally occupied by the brass hose fitting (Figure 1.4).

8.Using a short No. 2 Phillips screw driver, thread the small fuel jet into the regulator casting. Do not over tighten.

Figure 1.4 - Demand Regulator

Any piping used to connect the generator to the fuel supply should be of adequate size to ensure the fuel pressure NEVER drops below 4 inches water colum for natural gas or 10 inches water col- umn for liquid propane for all load ranges.
