28 Installation Guidelines For Australian 50 Hz Air-Cooled Generators

Checking Gas Line Connections

Check Gas Pressure

1. Check gas pressure at the regulator in the

generator by following these steps.

• Close gas supply valve.

• See Figure 5-7. Remove the top gas pressure test

port from the regulator and install the gas pressure

tester (manometer).

Figure 5-7. Checking Pressure with Manometer

• Open the gas supply valve and verify the pressure

is within the specified values.

• Record static gas pressure:

NOTE: Gas pressure can also be tested at the fuel shut-

off valve shown in Figure 5-2 if the valve is equipped with

a manometer port.

NOTE: See the owner’s manual or the spec sheet for

proper fuel pressure specifications. If the gas pressure is

not within specifications, contact the local gas supplier.

2. Close gas valve when completed. Keep manome-

ter connected for future tests of the generator while

starting, running, and under loads.

Perform Leak Test

All products are tested at the factory before shipping to

ensure the performance and integrity of the fuel system.

However, it is important to perform a final fuel system

leak test before starting the generator. The entire fuel

system should be tested from supply to regulator.

See Figure 5-8. Perform a final fuel system leak test

after generator installation. The test will identify possible

leaks at all connection points (A).

It is best practice to perform a fuel system leak test

during normally-scheduled maintenance.

Figure 5-8. Connection Points to Leak Check

Check for leaks by spraying all connection points with a

non-corrosive gas leak detection fluid. The solution

should not be blown away or form bubbles.

DANGER

Explosion and fire. Fuel and vapors are extremely

flammable and explosive. No leakage of fuel is

permitted. Keep fire and spark away. Failure to do

so will result in death or serious injury.
