3. Gas Hook-up Installation for Natural Gas or LPG (if needed)
You can power this generator with gasoline, natural gas (NG), or propane (LP) gas. The generator
is designed so that it is easy to switch between fuel sources. However, there are special initial
hook-up requirements for natural gas and propane:
WARNING:
If you choose to operate the generator on NG or LPG, you must have the fuel line system
installed by a certified gas technician.
Specific requirements for each type of hook-up are given below:
Natural Gas (NG)
Hook-up
Contact your gas utility company for installation of a natural gas hook-
up for the generator.
WARNING:
Natural gas is a highly explosive gas. All natural gas hook-ups must
be completed by trained personnel from your natural gas utility
company and inspected as required by your local building code.
♦ This product is designed to operate on NG at a gas pressure range of 4 to
6 ounces per square inch (7”-11” of water column) and requires a
minimum NG flow rate of 3.25 CFM.
♦ The standard gas pressure normally delivered to your building by your
utility company may be higher or lower than the required 4-6 ounces per
square inch (7”-11” of water column):
o If your standard delivery pressure exceeds 4-6 ounces per square
inch (7”-11” water column), you will need a pressure-reducing
regulator installed. Excessive gas pressure will permanently
damage this product and void the warranty if the generator is not
installed correctly with a pressure-reducing regulator as needed.
Note: The regulator supplied with this product is NOT a
pressure-reducing regulator, but one can be supplied
and installed by your gas utility technician at the time
of fuel system hook-up.
o If your standard delivery pressure is lower than 4-6 ounces per
square inch (7”-11” water column), you will need changes to your
natural gas service to provide elevated delivery pressure. In
addition you will need to have a pressure-reducing devices installed
for your other natural gas appliances.
Propane (LPG)
Hook-up Contact your local propane supplier to install a propane fuel system for
the generator.
WARNING:
LPG is a highly explosive gas. A qualified propane technician
must make the valve and hose connection between the propane
tank and generator in accordance with all local regulations and
electrical codes. All LPG hook-ups should be completed by
trained personnel from propane supplier and inspected as
required by your local building code.
