Ng To Lpg Conversion - Kohler KG2204 Operation

OPERATION

NG to LPG Conversion

The KG2204 engine is easily configurable for use with
either NG or LPG. System configuration for NG or LPG
requires a mechanical setting on the fuel pressure
regulator and an electrical setting change at the ECM.
These adjustments will ensure that the proper fuel and
spark timing is supplied to the engine.
NOTE:
The fuel pressure regulator is factory preset for NG.
When using NG, no mechanical adjustment is required.
Accidental starts can cause
severe injury or death.
Disconnect and ground spark
plug leads before servicing.
Before working on engine or equipment, disable
engine as follows: 1) Disconnect spark plug leads.
2) Disconnect negative (–) battery cable from battery.
Before disconnecting negative (–) ground cable,
make sure all switches are OFF. If ON, a spark will
occur at the ground cable terminal which could cause
an explosion if hydrogen gas or LPG/NG fuel vapors
are present.

WARNING
Fire. Can cause severe injury or death.
Do not smoke or permit flames or sparks near fuels or
the fuel system.

WARNING
Explosive fuel can cause fires and
severe burns.
If a gaseous odor is detected,
ventilate the area and contact an
authorized service technician.
LPG (Liquefied Petroleum Gas) is extremely
flammable and tends to settle in low areas where a
spark or flame could ignite the gas. Do not start or
operate this engine in a poorly ventilated area where
leaking gas could accumulate and endanger the
safety of persons in the area.
NG (Natural Gas) is extremely flammable, is lighter
than air, and rises. Do not start or operate this engine
in a poorly ventilated are where leaking gas could
accumulate and endanger the safety of persons in the
area.
To ensure personal safety, installation and repair of
LPG/NG fuel supply systems must be performed only
by qualified LPG/NG system technicians. Improperly
installed and maintained LPG/NG equipment could
cause the fuel supply system or other components to
malfunction, causing gas leaks.
Observe federal, state, and local laws governing
LPG/NG fuel, storage, and systems.
