NOTICE

NFPA Standard No. 58 requires all persons handling and operating propane

to be trained in proper handling and operating procedures.

The required components in a propane vapor fuel system are as follows:

Component Description

Propane Tank Make sure to identify and use the correct tank size based on fuel flow

requirements and the lowest average temperature for your region. If the

tank is sized incorrectly, the generator set could run out of fuel. Refer to

the Fuel Line Selection appendix.

Shutoff Valve Useful during installation or in the event of a leak (may be required to

meet local codes).

Primary Regulator Located at the tank outlet, the primary regulator reduces the tank

pressure to the working pressure in the fuel supply line. Primary and

secondary regulators must be properly matched for a safe and functional

system. Consult with your propane supplier to ensure that the regulators

are properly sized.

Secondary

Regulator

Located near the generator set, the secondary regulator reduces the

higher line pressure to a working pressure that matches the

requirements in the Model Specifications section. Higher pressure before

the secondary regulator is necessary to ensure that there is enough fuel

available at the secondary regulator for a fully loaded generator set.

Fuel Line Connects to the fuel supply. It must be sized properly using the propane

fuel line sizing charts (refer to the Fuel Line Selection appendix).

Installation must comply with all national, state, and local codes.

Cummins Flexible

Fuel Line

Attached to radiator guard. Protects the fuel system from vibration,

expansion, and contraction.
