Checking Gas Line Connections
1. Remove top lid and rear panel.
2. Check for leaks by spraying all connection points
with a non-corrosive gas leak detection fluid. You
should not see the solution be blown away or form
bubbles.
3. Check 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 (see Figure 5-4 ) and install the gas
pressure tester (manometer).
• Open the gas supply valve and verify the
pressure is within the specified values.
NOTE: Gas pressure can also be tested at the
manometer port on the fuel shut-off valve shown in
Figure 5-2 .
NOTE: See Fuel Requirements and Recommendations
for proper fuel pressure specifications. If the gas pressure
is not within specifications, contact the local gas supplier.
4. Close gas valve when completed.

socket screws.
