22 Installation Guidelines for 60 Hz Air-Cooled Generators
Installing and Connecting Fuel Lines
IMPORTANT NOTE: Natural gas and LP vapor are
highly volatile substances. Strictly adhere to all safety
procedures, codes, standards, and regulations.
Fuel line connections should be made by a certified
contractor familiar with local codes. Always use AGA-
approved gas pipe and a quality pipe sealant or joint
compound.
Verify the capacity of the natural gas meter or the LP tank
to provide sufficient fuel for both the generator and other
operating appliances.
Shutoff Valve
See Figure 5-2. The generator will require an external
manual shut-off valve (A) on the fuel line. The valve must
be easily accessible.
NOTE: Local codes determine the proper location.
Figure 5-2. Sediment Trap, Fuel Shut-Off Valve with
Manometer Port, and Flexible Fuel Line
Figure 5-3 illustrates a fuel shut-off valve with a
manometer port for making fuel pressure checks. This
optional accessory valve permits making pressure
checks for diagnostic purposes without going into the
generator enclosure.

Valves available through your local IASD:
• 1/2” ball valve, part number 0K8752
• 3/4” ball valve, part number 0K8754
• 1” ball valve, part number 0K8184
• 1-1/4” ball valve, part number 0L2844
• 1-1/2” ball valve, part number 0L2845
Flexible Fuel Line
See Figure 5-2. When connecting the fuel line to the
generator, use a listed assembly meeting the
requirements of ANSI Z21.75/ CSA 6.27—Connectors for
Outdoor Gas Appliances and Manufactured Homes or
AGA-approved flexible fuel line (B) in accordance with
local regulations.
The flexible fuel line shall not be connected directly to the
generator fuel inlet. Always connect the 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.
NOTE: Follow all installation instructions and warnings
provided with the flexible fuel line. Do not remove any
labels or tags.
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
according to local codes. See the owner’s manual for
more information.

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.
