SAFETY
l Only use natural gas hoses that comply with local, state,
or federal laws. Hose requirements may vary in different
regions. Check with the authority having local jurisdiction
(AHJ).
l Verify that the natural gas supply line from the house
was properly installed by a qualified plumber and that
the natural gas hose is securely connected before using
the generator.
l Before starting the engine, purge the natural gas supply
line and perform a leak test.
l Always disconnect the generator and natural gas hose
from the natural gas supply line when the gas supply is
being pressure tested.
l Keep the natural gas hose and natural gas supply line away
from the muffler and other heated surfaces.
l Keep a fire extinguisher near the generator at all times.
LEAK TESTING
See Figure 4.
NOTICE
Connections on the hose and the nat-
ural gas/propane inlet were tested at the factory to
make sure there were no gas leaks. However, ship-
ping and handling may have loosened connections.
We recommend that you always test for leaks before
using the generator.
To test for natural gas (NG) leaks:
l Connect the natural gas hose to the natural gas/propane
inlet on the generator and to the natural gas supply line.
l Brush the inlet, hose connections, and gas supply valve
with a soapy solution made of a 20/80 mixture of mild soap
and water.
l If bubbles begin growing, there is a leak.
• If the leak is at the inlet, contact customer service. DO
NOT USE THE GENERATOR.
• If the leak is at the hose connections, reinstall the hose
securely and perform the check again. If the leaks persist,
DO NOT USE THE GENERATOR.
• If the leak is at the natural gas supply line, DO NOT
USE THE GENERATOR.
To test for LPG/Propane leaks:
l Connect the LPG/propane hose to the natural gas/propane
inlet on the generator and to the cylinder valve.

l Open the cylinder valve. If you hear a rushing sound, im-
mediately turn off the cylinder valve. This noise indicates
a significant leak at the connection. Replace the cylinder
or have it repaired.
l Brush the inlet, hose connections, and LP gas cylinder with
a soapy solution made of a 20/80 mixture of mild soap and
water.
l If bubbles begin growing, there is a leak.
• If the leak is at the inlet, contact customer service. DO
NOT USE THE GENERATOR.
• If the leak is at the hose connections, reinstall the hose
securely and perform the check again. If the leaks persist,
DO NOT USE THE GENERATOR.
• If the leak is at the natural gas supply line, DO NOT
USE THE GENERATOR.
