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 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 capacity of NG meter or LP tank to pro-
vide sufficient 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
illustrates a fuel shutoff valve with a
Figure 5-3
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.

Flexible Fuel Line

See Figure 5-2. When connecting flexible fuel
line (B) to 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 in accordance
with local regulations.
Flexible fuel line must not be connected
directly to generator 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 possi-
bility 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 horizontally, 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 connec-
tion has an integrated sediment trap.
The sediment trap must be cleaned periodi-
cally according to local codes. See owner's
manual for more information.
