Installation Manual
Piping must be of the correct size to maintain the
required supply pressures and volume flow under varying
conditions.
• Use an approved pipe sealant or joint compound on all
threaded fittings to reduce the possibility of leakage.
• Installed piping must be properly purged and leak tested,
in accordance with applicable codes and standards.

• Before placing the Home Standby Generator into service, the
fuel system lines must be properly purged and leak tested.
• NO leakage is permitted.
Consider the following factors when planning to
install the fuel supply system:
The Home Standby Generator engine is fitted with a fuel
mixer system that meets the specifications of the California
Air Resources Board for "tamper-proof" dual fuel systems.
The unit will run on natural gas or liquefied propane.
• A minimum of one manual shutoff valve should be placed
in the fuel supply line and located outside the building to
facilitate servicing the generator.
• Natural gas fuel supply pressure at the generator's fuel
inlet port should be between 5 to 7 inches of water (in.
W.C.) at full load. LP fuel supply pressure should be I I to
14 inches of water (in.W.C.) at full load.
The Home Standby Generator unit has been
factory set to run on natural gas. If you need to
change from natural gas to LP gas, the unit will need to be
reconfigured, as described on page 13.
It is recommended that the fuel connection incorporate
the following components:
• A manual fuel shut-off valve located in the interior of the
building.
• A manual fuel shut-off valve located outside the building,
just before the generator unit.
• The termination of hard piping should include a sediment
trap.
• A manometer port should be provided.
The manometer port permits temporary installation of a
manometer (Figure 5), to ensure that the engine receives
the correct fuel pressure to operate efficiently throughout
its operating range.
When the initial test runs are completed, the manometer is
removed and the port is plugged.A typical final fuel
connection assembly is shown in Figure 6.
