Connecting LPG/ NG Fuel
~
WARNING! Liquid Petroleum gas (LPG) and Natural Gas (NG) are extremely
flammable which could cause burns or fire resulting in death or serious injury.
e The fuel supply line must always be shut off when the engine is not running. Failure to shut
off fuel may allow fuel to leak at the generator.
e Do not place the LPG/NG sources in the path of muffler outlet or near any ignition source.
e Keep a fire extinguisher near the generator all the time.
e Do not use or store LPG/NG portable sources not in use near generator or in a building, garage
or enclosed area.
e All LPG/NG supply/ piping lines must be installed bya qualified plumber.
e If you smell gas, close off a II gas sources and contact a qualified plumber to inspect and
repair the LPG or NG system.
Prior to each days first use spray a soapy water solution on LPG/NG fuel connections to check
for leaks.
e Never use a gas container, LPG/ NG connector hose, LPG cylinder or NG source that appears
to be damaged.
e Do not connect or disconnect the LPG/ NG source in an enclosed area.
e LPG is heavier than air and can accumulate in confined/ low spaces if there is a leak.
NOTICE If a fuel supply connection is necessary it must be installed in accordance with all local
codes or regulations, or in the absence of local codes or regulations, in accordance with the
National Fuel Gas Code (NFPA 54/ANSI 2223.1) and CSA B149.1 (Natural Gas and Propane
Installation Code). as applicable. If possible the fuel supply connection should be close to the
outdoor operating location. This will reduce the cost of the flexible fuel run. An approved flexible
fuel line must be installed between the generator LPG/NG Hose Connector (Inlet) and the fuel
supply connection. In no case should this information be interpreted to conflict with any local,
state, or national code. If in doubt, always follow local codes.
e Always keep the LPG cylinder in an upright position.
e Use only DOT LPG cylinders in vapor service with type 1, right hand ACME threads. Verify the
re-qualification date on the cylinder has not expired.
e All new cylinders must be purged of air and moisture prior to filling. The purging process
should be done by your propane gas supplier.
Attach the LPG regulator hose assembly (included) to the LPG hose connector (inlet) on the control
panel of the generator. Tighten the nut with a 19 mm or adjustable wrench. Remove the safety plug
or cap from the LPG cylinder valve. Attach the LPG regulator to the cylinder valve. Do not use a
wrench to tighten LPG cylinder nut. Tighten the nut by hand clockwise to a positive stop. Using a
wrench may damage LPG cylinder components.
