TROUBLESHOOTING FOR GASEOUS FUEL SYSTEM
GASEOUS FUELS ARE HIGHLY COMBUSTIBLE AND CAN CAUSE
EXPLOSIONS, FIRE, INJURY, OR DEATH! THE FUEL SUPPLY SYSTEM
MUST ONLY BE INSTALLED AND ADJUSTED BY AN EXPERIENCED,
PROFESSIONAL TECHNICIAN USING APPROVED PIPING AND
COMPONENTRY.
PRIOR TO MAKING ANY ADJUSTMENTS THAT WILL TAKE THE
GENERATOR SET OUT OF IT'S FACTORY PRESET CONDITION,
PLEASE NOTE THE CONDITION / SETTING OF THE ADJUSTING
DEVICE. THIS WILL ALLOW YOU TO RETURN TO THE FACTORY PRESET CONDITIONS IF IN
THE EVENT OF MAKING AN ADJUSTMENT THE GENERATOR SET'S PERFORMANCE GETS
WORSE.
Prior to troubleshooting the gaseous fuel systems in regards to an engine not
starting, make sure that that the engine has ignition. If the engine does not have a
'spark', the problem is not due to a faulty fuel supply, but rather is due to a problem
in the engine control circuitry or the engine itself.
BASIC DESCRIPTION
The gaseous fuel system on your generator operates on 6 ounces of pressure. If the fuel is
liquid propane (LP), it must be first vaporized before being delivered to the generator. Once at
the generator, and electric valve keeps fuel from flowing unless the engine is running. Inside
the generator is a regulator (called the secondary regulator) that delivers fuel based on engine
vacuum.
Proper maintenance is key to reliable performance. We recommend only those skilled and
licensed for repair of gaseous fuel powered generating systems be enlisted to service this
product. This basic guide is to assist those knowledgeable with generators in correction of fuel
related operation and starting problems.
INITIAL CHECKS
v Fuel supply is on and available at the fuel valve.
v Engine has spark and rotates at normal speed (if not, consult the engine operating guide for
assistance in your area).
v Battery is charged and connected properly
v Assume nothing. If you have not checked it, consider it not checked.
