Installation Guide
components become extremely hot during operation. Make sure unit is disconnected from main
power and main gas lines before converting
Two fuel connections on the fuel block allow eld conversion between natural gas (NG) and Liquid Propane
(LPG). The fuel metering valves are factory-set and sealed to provide the best possible hot and cold starting.
Use the following procedure to convert fuel from one type to another.
Natural Gas (NG) and Liquid Propane (LPG) Conversion
• Use a pressure reducing valve to reduce LPG pressure supply.
• Pushing the button as attached pictures show below to the natural
gas or LP vapor per the fuel which you want to use. Push in for
LPG and out for NG.
LPG = button in
Liquid propane (LP Vapor) NG = button out
In engines set up to run on Liquid propane, please check the fuel
supply pressure, lower or higher pressure range will result in
equipment failure. Inlet pressure 1.7kPa to 3.5kPa, and gas line
should be no longer than 16 feet or 5 meters, the inner diameter shall
not be less than (0.63”) or 16mm.

INSTALLING & CONNECTING GAS LINES
1. Natural gas and LP Vapors are highly explosive
substances; you must follow all safety, codes,
standards and regulations.
Use a certied plumber or licensed contractor familiar with
local codes to make all gas line connections. Always use
AGA-approved gas pipe and a quality pipe sealant or joint
compound. Verify the capacity of the natural gas meter or
the LP tank in regards to providing sufcient fuel for both
the generator and other operating appliances.
2. Most all applications will require an external manual shutoff valve on the fuel line.
3. Only use UL Listed or AGA-approved exible fuel line in accordance with local regulations, when connecting
the gas line to the generator. The section of exible fuel line is to ensure that vibration from the generator
does not create a gas leak at a connection point. Because of this, it’s important the fuel line be installed
with as few connection points and bends as possible.
4. Do not bend exible fuel line to avoid using an elbow. Bending the exible fuel line decreases its ability to
absorb vibrations and defeats the pur p o s e . I t a l s o p revents smooth fuel ow.
5. After checking for leaks, check the gas pressure at the REGULATOR to make sure there’s enough gas
pressure for generator operation. See Owner’s Manual for fuel pressure specications.
If not within these limits, contact your local gas supplier.
6. After checking and testing gas pressure regulator, close the main shutoff valve.
