Page 23: Section 5 Gaseous Fuel Systems
Gaseous Fuel Systems Section 5 Gaseous fuels, such as LP and natural gas, are highly volatile and their vapors are explosive. LP gas is heavier than air and will settle in low areas. Natural gas is lighter than air and will settle in high areas. Even the slightest spark can ignite these fuels and cause an explosion. -
Page 24: Lp-Vapor Withdrawal System
Gaseous Fuel Systems between the rigid supply piping and the gas connection at the generator, and must be installed straight without bends or kinks. The primary regulator outlet and the generator connection point must be sized correctly to provide the gener- ator with the required volume and pressure when it is operating at 100% of its rated load. -

Gaseous Fuel Systems 5.4.2— Definitions The following definitions are provided for use in this manual. Table 5-1. Definitions Term Description The design pressure loss in the system under maximum probable flow conditions, from the point of deliv- Allowable Pressure ery to the inlet connection of the generator set, shall be such that the supply pressure at the generator is Drop greater than or equal to the minimum pressure required by the generator at its full load capacity. -
Page 27: Operating Fuel Pressure
Gaseous Fuel Systems The required fuel pressure to the unit is measured before the fuel shutoff solenoids at the inlet to the unit • mounted regulator. A 1/8 inch pipe port in the pressure regulator body, or in the piping just before the pressure regulator, is provided for this purpose. -
Page 28: Recommended Fuel Pressure Regulators
Gaseous Fuel Systems 5.4.7— Recommended Fuel Pressure Regulators Use only direct acting fuel pressure regulators, such as those made by Fisher® or Maxitrol® or any other listed regu- lator manufacturer. 5.4.8— Primary Fuel Pressure Regulator The following are the recommended “best practices” with regard to specifying, sizing, and installing the primary fuel pressure regulator. - Page 29 Gaseous Fuel Systems There are several pipe sizing programs available for use on the Internet and from various manufacturers. If used it is highly recommended that the minimum pressure drop value always be used (0.5 inches w.c or less). This will ensure that the piping system is sized correctly to handle the generator set volume at full load, and during cranking and load transients, while also remaining above the minimum operating pressure.

Gaseous Fuel Systems Length Height Propane Diameter Figure 5-3. Typical Propane Tank Dimensions NOTE: The minimum LP tank size is 250 gallons, unless unit calculations dictate use of a larger tank. Vertical tanks, which are measured in pounds, will not usually meet the minimum tank size (250 Gallons x 4.20 Pounds = approximately a 1050 pound vertical tank minimum). -
Page 33: Final Test Procedure
Gaseous Fuel Systems NOTE: Below 45º F. the neoprene core of the plug does not recover it's original shape as rapidly as it would at higher temperatures. Therefore, upon removal of the gauge adapter probe, the valves may not close fully and immediately, or they may remain slightly open until the operating temperature is above 45º... - Page 34 Gaseous Fuel Systems Cranking Pressure. Pressure when the unit is cranking. Must not drop more than 1 in. w.c. below Static Pres- sure or below the minimum pressure listed in the unit specification sheet. If it does, it may indicate that fuel sup- ply piping is not correctly sized, or that primary regulator is improperly sized or mounted too close to the generator connection point.

Electrical System Storage batteries give off EXPLOSIVE hydrogen gas. This gas can form an explosive mixture around the battery for several hours after charging. The slightest spark can ignite the gas and cause an explo- sion. An explosion can shatter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. - Page 42 Electrical System Red Lead From Starter A = Protective Cover Black Lead B = Battery Strap To Frame Battery Figure 6-6.
