20 Installation Guidelines for 60 Hz PowerPact™
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 and Figure 5-3 .
NOTE: Local codes determine the proper location.
Figure 5-2. Accessory Valve with Manometer Port
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 IASDs:
• 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
Flexible Fuel Line
When connecting the gas 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 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. See
C in Figure 5-3 .
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. Install the
recommended sediment trap as illustrated. See
D in
Figure 5-3 .
