3. Where the gas line is to enter the generator, install a T-fitting
to allow for gas pressure monitoring. On one opening of the
fitting install a ¼" NPT nipple and threaded plug. In some
cases a sediment trap may also be installed.
4. 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.
5. 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.
6. After checking for leaks, check the gas pressure at the
T-fitting installed earlier 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.
7. When finished checking the gas pressure, close the manual
shutoff valve.
