When connecting the gas line to the generator, use a short 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.
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.
Check the gas pressure at the secondary regulator to make sure there’s enough pressure for proper generator operation.
The local gas supplier is responsible for ensuring adequate pressure, so if the pressure is too low, or if it’s greater than 14 inches of water column, contact the gas supplier.
When you’ve finished checking the gas pressure, close the manual shutoff valve.
