Fuel Conversion/Gas Connections
Installing and Connecting Gas
Lines
Both natural gas and LP vapor are highly combustible
substances, so strict adherence to all safety procedures,
codes, standards and regulations is essential.
Gas line connections should be made by a certified
plumber 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
in regards to providing sufficient fuel for both the
generator and other operating appliances.

Shutoff Valve

Most applications will require an external manual full flow
shut-off valve on the fuel line. The valve must be easily
accessible. See A in Figure 5-2
NOTE: Local codes determine the proper location.

NOTE: Figure 5-2 (B) illustrates a fuel shut-off valve with
a manometer port for making fuel pressure checks. This
accessory valve permits making pressure checks without
going into the generator enclosure.
Valves available through Generac and Independent
Authorized Service Dealers:

Flexible Fuel Line

When connecting the gas line to the generator, use UL
Listed or AGA-approved flexible fuel line in accordance
with local regulations. See C in
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. It is important that the line be
installed with as few bends as possible. The flexible fuel
line should be horizontal and plumbed parallel to the
back of the generator.
CAUTION
Equipment damage. Do not bend flexible fuel line.
Bends in fuel line restrict fuel flow and reduce
ability to absorb vibration.

Sediment Trap

Some local codes require a sediment trap. Install the
recommended sediment trap as illustrated. See D in
Figure 5-3.
