Product Manual A

4. Installation7-2018

Gaseous-fuel supply system design, materials, components, fabrication, assembly,

installation, testing, inspection, operation, and maintenance must comply with the

applicable codes. See NFPA Standards No. 37, 54, and 58. If this is a seismic

installation, refer to IBC codes and standards. Where seismic installation is

required, there may be specific anchorage requirements for the generator set and

other installed components.

Most codes require a manual shutoff valve ahead of a flexible fuel hose. The

generator set includes electric (battery-powered) shutoff valves.

NOTICE

It is recommended that a shutoff valve be located near the generator set for

emergency shut off or servicing the generator set. Follow applicable codes.

Until the generator set is connected, cap the fuel line stub-up at the generator set to

prevent dirt from entering and gas from discharging if the gas supply shutoff valve is

opened accidentally.

To determine the required capacity, refer to the Fuel Line Selection section.

Fuel Line Connections

WARNING

Fuel presents the hazard of fire or explosion that can result in severe

personal injury or death. Do not smoke or allow any flame, spark, pilot light

or other ignition sources near fuel or in the installation area. Read the

important safety precautions in this manual.

1. Refer to the Outline and System Drawings appendix for the location of the fuel

supply connection through the side of the generator set.

2. Install a flexible fuel hose, which must be used between the engine's fuel

system and fuel supply line to protect the fuel system from damage caused by

vibration, expansion and contraction. The fuel hose must be installed according

to all applicable codes and standards.

Installing Fuel Lines

The basic components required for fuel line installation are as follows:

• Flexible fuel line (attached to the radiator guard)

• Fuel line

• Shutoff valve

• Fuel supply

To install the fuel lines:

1. Connect a flexible fuel line to the fuel connection ports on the generator set.

2. Connect the opposite end of the flexible fuel line to the fuel source line near the

shutoff valve.
