Gaseous Fuel System
Before Installing Fuel System
Consult with the user regarding any technical considerations
that might affect their installation plans. The entire flexible
steel fuel line must be visible for periodic inspection and
must not be concealed within nor contact or run through any
wall, floor, or partition. The piping should be of a material
that conforms to national rules and regulations of the
respective country, rigidly mounted and protected against
vibration.
Piping should be protected from physical damage where
it passes through flower beds, shrub beds, and other
cultivated areas where damage could occur.
1. Install the flexible steel fuel line
(B)
(supplied) between
the generator fuel inlet port
(A)
and rigid piping. This
will prevent thermal expansion, contraction, or any
generator movement from causing excessive stress on
the piping material.
2. A union
(C)
or flanged connection shall be provided
downstream to permit removal of generator.
3. A manometer port should be provided
(D)
to enable
measurement of fuel pressure. A digital manometer,
Part Number 19495, is available at your local Briggs &
Stratton authorized service provider. When the initial
test runs are completed, the manometer is removed and
the port is plugged.
4. The termination of hard piping should include a
sediment trap
(F)
where condensate is not likely to
freeze. Where formation of hydrates or ice is known to
occur, piping should be protected against freezing.
5. A minimum of one accessible, approved manual shutoff
valve
(E)
shall be installed in fuel supply line per
national rules and regulations of the respective country.
Piping must be of the correct size to maintain the required
supply pressures and volume flow under varying generator
load conditions with all gas appliances connected to the fuel
system turned on and operating.
Use a pipe sealant or joint compound approved for use with
NG/LPG on all threaded fittings to reduce the possibility of
leakage.
Where local weather conditions include earthquake,
tornado, unstable ground, or flood hazards, special
consideration shall be given to increase strength and
flexibility of piping supports and connections.
Purge and leak test the installed piping in accordance with
applicable national rules and regulations of the respective
country.

WARNING
Propane and Natural Gas are
extremely flammable and explosive, which could
cause burns, fire or explosion resulting in death
or serious injury. The slightest spark could ignite
these fuels and cause an explosion. LP gas
is heavier than air and will settle in low areas.
Natural gas is lighter than air and will collect in
high areas. Before installing and/or servicing
fuel supply system:
DO
• Do
install fuel supply system according to
applicable national rules and regulations of
the respective country.
• Do
properly purge and leak test fuel system
lines.
• Do
wipe up any oil spills immediately.
• Do
keep the area near the generator clean
and free of debris.
DO NOT
• Do not
permit leakage.
• Do not
leave combustible materials in the
generator compartment.
• Do not
operate engine if smell of fuel is
present or other explosive conditions exist.
• Do not
smoke around generator.
• Do not
have any open flames around
generator.
