1.8 Fuel Conversion

The multi-fuel system allows conversion from natural
gas to LPG (or vice-versa) in the field while maintaining
emissions-standard compliance. A trained technician
or an authorized distributor/dealer can convert the fuel
system.
After converting the fuel system, change the Fuel Type
setting on the controller. See the Operation Manual for
instructions to change settings at the controller, or use a
personal (laptop) computer and Kohlerr SiteTecht
software to change the setting.
Rating Change
Converting the fuel will change the generator set rating.
See the generator set specification sheet for ratings with
natural gas and LP. Order a new nameplate with the
updated rating and fuel information from an authorized
distributor/dealer, if necessary. Provide the following
information from the original nameplate:
D Model Number
D Spec Number
D Serial Number
D Fuel (original and new)
D kW
Attach the new nameplate over the old one. Do NOT
cover the UL listing information on the old nameplate.

1.8.1 Fuel Conversion, 14RESA/RESAL
Equipped with Fuel Block
Note: Model 14RESA/RESAL generator sets built
before June 26, 2014 use a fuel block for the fuel
type selection. See Figure 1-9 and use the
instructions in this section for fuel conversion.
Model 14RESA/RESAL generators built June 26,
2014, or later are not equipped with the fuel block.
These units use fuel orifice fittings installed in the
hose fitting at the fuel regulator. See Section
1.8.2 for fuel conversion instructions.
Two fuel connections on the fuel block allow field-
conversion between natural gas and LPG. 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 may violate federal or state
laws.
Use the following procedure to convert from natural gas
(NG) to LPG. See Figure 1-9 for the fuel system
component locations.
