Lp Gas Fuel System - Kohler 4CKM Operation And Installation Manual

LP Gas Fuel System

Use a flexible hose designated for use with LP gas
between the generator set and main tank. Care must be
taken when routing the fuel line. A two inch minimum
clearance is required between the fuel line and any bare
exhaust components. Electrical wiring can not be tied to
any fuel lines and should be routed so that it will not
inadvertently contact fuel lines. If the flexible hose
passes through sheet metal, install grommets or clamps
to prevent hose abrasion. The LP fuel system shall
conform to section 3-6.4 of NFPA58, " Storage and
Handling of Liquified Petroleum Gases."
For LP gas system, use UL classified pipe joint sealing
compound to prevent dangerous fuel leaks. Use a
sealing compound approved for use with LP gas. Apply
UL classified sealing compound at all fuel line pipe
joints.
After all the LP connections have been completed, the
entire system shall be test pressurized to 6-8 ounces
(10-14 inches water column). Test the connections for
leakage with soapy water or bubble solution. Do not use
solutions that contain ammonia or chlorine, since the
soap will not bubble for an accurate leakage test.
The gas and supply pressure should not exceed six
ounces. To check inlet pressure, remove plug on fuel
inlet for gas regulator. Insert ounce pressure gauge or
manometer. Adjust operating pressure to 4-6 ounces or
7-11 inches water column; inlet pressure is adjusted on
primary regulator.
The use of flexible fuel lines should be limited to areas
where vibration and/or movement of connected
components is likely (such as main fuel line to generator
set). Use seamless steel tubing wherever long main fuel
lines are required.

NOTE
WARNING
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling, storing,
and using fuels.
Explosive fuel vapors can cause severe injury or
death. Fuel leakage can cause an explosion. Check LP
vapor gas fuel system for leakage using a soap-water
solution with fuel system test pressurized to 6-8 ounces
per square inch (10-14 inches water column). Do not
use test solutions that contain ammonia or chlorine,
since the soap will not bubble for an accurate leakage
test.
Explosive fuel vapors can cause severe injury or
death. Fuel leakage can cause an explosion. Check LP
vapor gas or natural gas fuel system for leakage using a
soap-water solution with fuel system test pressurized to
6-8 ounces per square inch (10-14 inches water
column). Do not use test solutions that contain
ammonia or chlorine, since the soap will not bubble for
an accurate leakage test.
Fuel leakage could cause an explosion. After all LP-gas
connections have been completed, the entire system
must be test pressurized to 6-8 ounces (10-14 inches
water column).
Gas pressure above 10 ounces can result in
non-operation of the gas valve.
