2. Most applications will require an external manual full flow
shutoff valve on the fuel line.
3. Where the gas line is to enter the generator enclosure. Install
a 3 - 5“ long piece of ½” black iron pipe threaded at both
ends (Not provided). Thread one end into the generator fuel
regulator using the reducing bushing provided. On the other
end of the pipe thread a ½” standard pipe Tee as shown (Not
provided).
4. Make sure the center leg of the Tee is pointing straight down
when fully tightened onto the pipe.
5. Thread a 3 – 4” long piece of ½” black iron pipe threaded
at both ends (not provided) into the Tee Fitting. Fully tighten.
Thread a ½” Pipe cap (not provided) to the other end of the
pipe. Fully tighten. This downward pointing pipe will serve as
a water and sediment trap and should be periodically emptied
once the generator is in service.
6. 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.
7. 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.
8. After checking for leaks, check the gas pressure at the
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.
Correct static fuel pressure should be:
• Natural Gas = 5-7 inches water column
• LP = 10-12 inches water column
9. When finished checking the gas pressure, close the manual
shutoff valve.
