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 Kohler

SiteTech

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:

Model Number

kVA

Spec Number

Amps

Serial Number

Volts

Fuel (original and new)

Attach the new nameplate over the old one. Do NOT

cover the UL listing information on the old nameplate.

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 equipment connected to the set, disable the

generator set as follows: (1) Press the generator set off/reset

button to shut down the generator set. (2) Disconnect the

power to the battery charger, if equipped. (3) Remove the

battery cables, negative (--) lead first. Reconnect the negative

(--) lead last when reconnecting the battery. Follow these

precautions to prevent the starting of the generator set by the

remote start/stop switch.

Explosive fuel vapors.

Can cause severe injury or death.

Use extreme care when handling,

storing, and using fuels.

WARNING

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.

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.
