3. When connecting the gas line to the generator, use the provided section of UL Listed or AGA-approved flexible
fuel line in accordance with local regulations. The purpose of the flexible fuel line is to ensure that vibration from
the generator does not cause a gas leak at one of the connection points, so it’s important that the line be installed
with as few bends as possible. Configure the sediment trap (if applicable or required by code) as illustrated.
4. Never bend the flexible fuel line to avoid using an elbow. Bending the flexible line decreases its ability to absorb
vibrations and defeats its purpose, as well as constricts the actual fuel flow. See Figure 5-4.
5. Check for leaks by spraying all connection points with a soap solution made of dishwashing soap and water. You
should not see the solution be “blown away” or form “bubbles”. Next, check the gas pressure at the regulator in
the generator by following these steps.
– Close gas supply valve.
– Remove the top gas pressure test port from the regulator, and install the gas pressure tester (manometer). See
Figure 5-5.
– Open the gas supply valve and ensure that the pressure is within the specified values.
6. Close gas valve when completed.
