6.15 Natural Gas

Natural gas is in a vapor state as supplied from the utility. This fuel system, therefore, consists of the same basic components and is used in the same general sequence as LP gas systems. When the heating content of the fuel falls below 1000 BTU, as it does with manufactured sewage and some natural gas fuels, the set will not produce rated power.

The primary regulator may or may not be furnished by the supplier. It is the responsibility of the supplier to insure that sufficient pressure is present at all times to operate the primary regulator. Installation, repair, and alteration to gas piping should be undertaken only by the supplier or with supplier’s permission. Piping should never be used to ground any electrical apparatus. The piping should be rigidly mounted but protected against damage from vibration. Where flexible connections are needed use only fuel line approved for gas fuels. See Figure 6-10.

6.16 Combination Gas-Gasoline

Most engines, especially the smaller models, will operate successfully on gas or gasoline without extensive modification or complicated mechanical changeover. With a combination gas-gasoline fuel system, changeover involves only a few simple steps.

These systems normally utilize a gaseous fuel as the primary fuel with gasoline for emergency operation. In some areas natural gas is available at reduced cost on an “interrupted service” basis. In some cases a by-product gas is the primary fuel, but it may at times be unavailable. Continued operation is assured under these conditions by switching over to gasoline. The changeover is done manually at the generator set.

Either a combination gas-gasoline carburetor or a gasoline carburetor with a gas adapter is used. Natural or LP gas can be used with these carburetor combinations.

With the exception of the carburetor and addition of a gas adapter, the combination gas-gasoline systems utilize the same basic components as those in the natural and LP gas systems. See Figure 6-11.
