Installing and Connecting Fuel Lines

DANGER
Explosion and fire. Fuel and vapors are extremely
flammable and explosive. No leakage of fuel is
permitted. Keep fire and spark away. Failure to do
so will result in death or serious injury.
IMPORTANT NOTE: NG and LP gas are highly vola-
tile substances. Strictly adhere to all safety proce-
dures, codes, standards, and regulations.
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 and other operating
appliances.

Fuel Shutoff Valve

See Figure 5-2. The generator will require an external
manual fuel shutoff valve (A) on the fuel line.
NOTE: Fuel shutoff valve must be installed at a readily
accessible location, and within 6 ft (1.8 m) of generator
fuel inlet.
Figure 5-2. Sediment Trap, Fuel Shutoff Valve with
Manometer Port, and Flexible Fuel Line
Figure 5-3 illustrates a fuel shutoff valve with a manome-
ter port for making fuel pressure checks. This optional
accessory fuel shutoff valve permits making pressure
checks for diagnostic purposes without going into the
generator enclosure.

Fuel shutoff valves available through an IASD:

Flexible Fuel Line

See
generator, use a listed assembly meeting the require-
ments of ANSI Z21.75/ CSA 6.27—Connectors for Out-
door Gas Appliances and Manufactured Homes or AGA-
approved flexible fuel line in accordance with local regu-
lations.
Flexible fuel line must not be connected directly to gener-
ator 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 to reduce possibility of a gas leak at one of
A
the connection points.
NOTE: Follow all installation instructions and warnings
B
provided with flexible fuel line. Do not remove any labels
C
or tags. Flexible fuel line must be installed horizontally,
and must be installed between fuel shutoff valve and
001816
generator fuel inlet.

Sediment Trap

See
trap (C). The fuel regulator connection has an integrated
sediment trap.
The sediment trap must be cleaned periodically accord-
ing to local codes. See owner's manual for more informa-
tion.
