Installation Manual
• Install flexible gaseous pipe (supplied) between the Home
Generator System Fuel Inlet port and rigid piping.
CAUTION!
Connector is not to be installed
underground or in contact with the ground.
_k CAUTION!
Entire flex connector must be visible
for periodic inspection and must not be concealed
within, contact, or run through any wall, floor, or
partition.
• 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.
Consider the following factors when planning to
install the fuel supply system:
The Home Generator System engine is fitted with a fuel
carburetion 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-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 Generator System 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 18.
It is recommended that the fuel connection incorporate
the following components:
• 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 6), 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 7.
