TP-6049 9/0230 Section 6 Installation
Single-fuel generator sets that are not
emission-certified do not have the emission decal. An
authorized distributor/dealer can convert the fuel
system from natural gas to LP vapor (or vice-versa) on a
non-certified unit. Converting the fuel system includes
adjusting the fuel metering valve and checking the
exhaust emissions. The generator set service manual
explains the adjustment procedures.
6.7.4 Multi-Fuel Systems
Generator sets with multi-fuel systems are CARB- and
EPA-certified for both natural gas and LP vapor fuels.
Multi-fuel units are equipped with the fuel block shown in
Figure 6-6 and have specification numbers beginning
with GM. The multi-fuel system allows conversion from
natural gas to LP vapor (or vice-versa) in the field while
maintaining emissions-standard compliance. A trained
technician or authorized distributor/dealer can convert
the fuel system.
6.7.5 Fuel Conversion (multi-fuel
models only)
Two fuel connections on the fuel block allow field-
conversion between natural gas and LP vapor. The fuel
metering valves are factory-set and sealed to comply
with applicable emission standards and to provide the
best possible hot and cold starting.

Note: Do not adjust the factory-sealed fuel-metering
adjustments on the fuel block. Changing the
fuel-metering adjustments on multi-fuel units
may violate federal or state laws.
The manufacturer ships the generator set with the fuel
system connected for natural gas. To convert to LP gas,
use the following procedure to move the fuel line from
the natural gas outlet port to the LP outlet port in the fuel
block (or from the LP outlet to the natural gas outlet to
convert from LP to natural gas). See Figure 6-6 for the
fuel block and fuel inlet locations.
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (--) lead first
when disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or connected equipment, disable the generator
set as follows: (1) Move the generator set master switch to the
OFF position. (2) Disconnect the power to the battery charger.
(3) Remove the battery cables, negative (--) lead first.
Reconnect the negative (--) lead last when reconnecting the
battery. Follow these precautions to prevent starting of the
generator set by an automatic transfer switch, remote
start/stop switch, or engine start command from a remote
computer.
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling,
storing, and using fuels.
