Section 1 — General Information

1.7FUEL REQUIREMENTS

AND RECOMMENDATIONS

With LP gas, use only the vapor withdrawal sys- tem. 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 1.8 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 column (0.18 to 0.25); and for liquid propane vapor, 10 inches to 12 inches of water column (0.36 to 0.43 psi).

A seperate gas line and regulator may be need- ed to assure proper gas pressure to the genera- tor. Low gas pressure can cause hard starting and could affect engine durability.

3.Remove the pipe plug from the LP (left) outlet port.

4.Install the brass hose fitting in the LP (left) outlet port.

5.Install the pipe plug in the NG (right) outlet port.

6.Connect the carburetor fuel hose to the LP (left) outlet port of the demand regulator.

7.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.

1.9RECONFIGURING THE

FUEL SYSTEM

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

1.Turn the main gas supply off.

2.Remove the carburetor fuel hose and the brass hose fitting from the NG (right) outlet port of the demand regulator (Figure 1.4).

Install the generator set, in its protective enclosure, outdoors, where adequate cooling and ventilating air is always available. Consider these factors:

•Install the unit where air inlet and outlet open- ings 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.

•Allow sufficient room on all sides of the generator for maintenance and servicing. A good rule is to allow three feet of space on all sides.

•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.

•Install the generator as close as possible to the transfer switch. HOWEVER, REMEMBER THAT LAWS OR CODES MAY REGULATE THE DISTANCE.

The genset must be installed on a level surface. The base frame must be level within two (2) inches all around.
