Fuel Conversion / Gas Connections
26 Installation Guidelines For 50 Hz Air-Cooled Generator Sets
Installing and Connecting Fuel Lines
IMPORTANT NOTE: NG and LP gas are highly vola-
tile substances. Strictly adhere to all safety proce-
dures, codes, standards, and regulations.
IMPORTANT NOTE: The fuel inlet to the generator
set has NPT threads. NPT threads are tapered and
require the use of pipe thread sealant.
Fuel line connections should be made by a certified con-
tractor familiar with local codes. Always use AGA-
approved gas pipe and a quality pipe sealant or joint
compound.
Verify capacity of NG meter or LP tank to provide suffi-
cient fuel for both the generator set and other operating
appliances.
Fuel Shutoff Valve
See Figure 5-3 . Local codes, standards, or regulations
may require an external manual fuel shutoff valve (A) to
be installed on the fuel supply line to the generator set.
The fuel shutoff valve must be readily accessible. The
installer is responsible for supplying this fuel shutoff
valve.
Figure 5-3. Sediment Trap, Fuel Shutoff Valve with
Manometer Port, and Flexible Fuel Line
NOTE: Fuel shutoff valve must be installed at a readily
accessible location, and within 1.8 m (6 ft) of generator
fuel inlet.
NOTE: Figure 5-4 illustrates a fuel shutoff valve with a
manometer port for making fuel pressure checks. This
optional accessory fuel shutoff valve permits making
pressure checks for diagnostic purposes without going
into the generator set enclosure.

Flexible Fuel Line
See Figure 5-3 . The generator set requires a flexible
connection to the fuel supply line. A flexible fuel line (B)
with NPT threads is included. The installer must verify
that any component used to connect the generator set to
fuel supply meets requirements of all applicable codes,
standards, laws, and regulations.
The flexible fuel line must not be connected directly to the
generator set fuel inlet. Always connect flexible fuel line
to an approved gas fitting.
The purpose of flexible fuel line is to isolate vibration from
the generator set to reduce possibility of a gas leak at
one of the connection points.
NOTE: Follow all installation instructions and warnings
provided with flexible fuel line. Do not remove any labels
or tags.
NOTE: Flexible fuel line must be installed horizontally
and has to be installed between the fuel shutoff valve and
generator fuel inlet.
Sediment Trap
See Figure 5-3 . Some local codes require a sediment
trap (C). The fuel regulator has an integrated sediment
trap with a 3/4 in NPT inlet for fuel supply connection.
The sediment trap must be cleaned periodically accord-
ing to local codes. See owner’s manual for more informa-
tion.
ISO000192
Fuel and vapors are extremely
flammable and explosive. No leakage
of fuel is permitted. Keep fire and
spark away.
