THE GASEOUS FUEL
SYSTEM
WARNING
Propane and Natural Gas are extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.
• LP gas is heavier than air and will settle in low areas.
• Natural gas is lighter than air and will collect in high areas.
• The slightest spark can ignite these fuels and cause an explosion.
The information provided below is to assist

be interpreted to conflict with applicable fuel gas
codes. Consult with your local fuel supplier or
Fire Marshall if questions or problems arise.
TO THE INSTALLER: Consult with the Home
Generator System owner(s) and convey any
technical considerations that might affect their
installation plans before applying these general
guidelines.
The following general rules apply to gaseous fuel system
piping:
• The piping should be of a material that conforms to
federal and local codes, rigidly mounted and protected
against vibration.
• Piping should be protected from physical damage where
it passes through flower beds, shrub beds, and other
cultivated areas where damage could occur.
• Install the flexible, gaseous hose (supplied) between the
Home Generator System Fuel Inlet port and rigid piping
to prevent thermal expansion or contraction from
causing excessive stress on the piping material.
CAUTION
The supplied flexible gaseous pipe is not to be installed
underground or in contact with the ground.
• The entire flexible gaseous pipe must be visible for periodic
inspection and must not be concealed within, contact, or run
through any wall, floor, or partition.
INSTALLATION

NOTE: Where local conditions include earthquake,
tornado, unstable ground, or flood hazards, special
consideration shall be given to increase strength and
flexibility of piping supports and connections.
• Piping must be of the correct size to maintain the
required supply pressures and volume flow under varying
generator load conditions with all gas appliances
connected to the fuel system turned on and operating.
• Use an approved pipe sealant or joint compound on all
threaded fittings to reduce the possibility of leakage.
• Installed piping must be properly purged and leak tested,
in accordance with applicable codes and standards.
WARNING
Propane and Natural Gas is extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.
• Before placing the Home Generator System into service, the
fuel system lines must be properly purged and leak tested.
• NO leakage is permitted.
Consider the following factors when planning to
install the fuel supply system:
The Home Generator System engine is fitted with a fuel
mixer system that meets the specifications of the California
Air Resources Board for "tamper-proof" dual fuel systems.
The unit will run on natural gas or liquefied propane vapor.
• A minimum of one accessible, approved manual shutoff
valve shall be installed in the fuel supply line within 6 ft
(1.8 m) of the Home Generator System. A union or
flanged connection shall be provided downstream from
this valve to permit removal of controls.
• Natural gas fuel supply pressure at the generator's fuel
inlet port should be between 5 to 7 inches of water (in.
W.C.) at full load. LP fuel supply pressure should be 11 to
14 inches of water (in.W.C.) at full load.
