1.6 Fuel System
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling,
storing, and using fuels.
WARNING
The fuel system. Explosive fuel vapors can cause severe
injury or death. Vaporized fuels are highly explosive. Use
extreme care when handling and storing fuels. Store fuels in a
well-ventilated area away from spark-producing equipment
and out of the reach of children. Never add fuel to the tank
while the engine is running because spilled fuel may ignite on
contact with hot parts or from sparks. Do not smoke or permit
flames or sparks to occur near sources of spilled fuel or fuel
vapors. Keep the fuel lines and connections tight and in good
condition. Do not replace flexible fuel lines with rigid lines. Use
flexible sections to avoid fuel line breakage caused by
vibration. Do not operate the generator set in the presence of
fuel leaks, fuel accumulation, or sparks. Repair fuel systems
before resuming generator set operation.
Gas fuel leaks. Explosive fuel vapors can cause severe
injury or death. Fuel leakage can cause an explosion. Check
the LPG vapor or natural gas fuel system for leakage by using
a soap and water solution with the fuel system test pressurized
to 6--8 ounces per square inch (10--14 inches water column).
Do not use a soap solution containing either ammonia or
chlorine because both prevent bubble formation. A successful
test depends on the ability of the solution to bubble.
Explosive fuel vapors can cause severe injury or death.
Take additional precautions when using the following fuels:
Propane (LPG)—Adequate ventilation is mandatory.
Because propane is heavier than air, install propane gas
detectors low in a room. Inspect the detectors per the
manufacturer’s instructions.
Natural Gas—Adequate ventilation is mandatory. Because
natural gas rises, install natural gas detectors high in a room.
Inspect the detectors per the manufacturer’s instructions.
Gas fuel systems operate on either LP vapor or natural
gas. Refer to the generator set specification sheet and
Section 1.6.3 for more detailed information on fuel
requirements.
Note: The fuel system installation must comply with the
National Electrical Coder (NEC) and applicable
local codes.
