Fuel Conversion / Gas Connections

Installing and Connecting Gas Lines

DANGER
IMPORTANT NOTE: Natural gas and LP vapor are
highly volatile substances. Strictly adhere to all safety
procedures, codes, standards, and regulations.
Gas 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

The generator will require an external manual shut-off
valve on the fuel line. The valve must be easily
accessible. See A in Figure 5-3.
NOTE: Local codes determine the proper location.
Figure 5-2. Accessory Valve with Manometer Port
NOTE: Figure 5-2 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.

Authorized Service Dealers (IASD):

Flexible Fuel Line

When connecting the gas line to the generator, use a
listed assembly that meets 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.
(000192)
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. See B in
NOTE: Follow all installation instructions and warnings
provided with the flexible fuel line. Do not remove any
labels or tags.

Sediment Trap

Some local codes require a sediment trap. The fuel
regulator connection has an integrated sediment trap.
See C in Figure
Figure 5-3. Sediment Trap, Fuel Shut-Off Valve with
Manometer Port, and Flexible Fuel Line
000743
The sediment trap must be cleaned periodically
according to local codes. See the owner's manual for
more information.
