1.6FUEL 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 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:

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.

1.8RECONFIGURING THE FUEL SYSTEM

◆1.8.1 7 KW, 410CC

To reconfigure the fuel system from NG to LP, follow these steps (Figure 1.3):

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 main gas supply (if connected).

2.Open the roof and remove the door.

3.Remove the battery (if installed).

4.Disconnect wire #0 and wire #14 from the gas solenoid on top of the demand regulator.

5.Remove the carburetor fuel hose from the outlet port of the demand regulator.

6.Remove the demand regulator by removing the fastener that retains the regulator mounting bracket.

7.Remove the square headed steel pipe plug from outlet port #1 and the brass hose barb fitting from outlet port #2.

8.Refit the brass hose barb fitting to outlet port #1 and the square headed steel pipe plug to outlet port #2.

9.Reverse procedure steps 1-5 to reinstall demand regulator.

10.Take the plastic plug supplied in the poly-bag with the generator and press it into the 3/4” hole on the bottom of the air cleaner base (Figure 4.6).

11.Reverse the procedure to convert back to natural gas.

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.
