24 Installation Guidelines for 60 Hz Air-Cooled Generators
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.
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
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 enclosure.

Fuel shutoff valves available through an IASD:
• 1/2 in ball valve, part number 0K8752
• 3/4 in ball valve, part number 0K8754
• 1 in ball valve, part number 0K8184
• 1-1/4 in ball valve, part number 0L2844
• 1-1/2 in ball valve, part number 0L2845
Flexible Fuel Line
See Figure 5-2. When connecting flexible fuel line (B) to
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
the connection points. Installation of a flexible fuel line is
a fuel gas code and installation requirement.
NOTE: Follow all installation instructions and warnings
provided with the flexible fuel line. Do not remove any
labels or tags. Flexible fuel line must be installed horizon-
tally, and must be installed between fuel shutoff valve and
generator fuel inlet.
Sediment Trap
See Figure 5-2. Some local codes require a sediment
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.

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.
