are also several general location guidelines that must be
met before the installation in considered complete.
Exhaust Side of the Generating Set
A - Exhaust outlet side of weatherproof enclosure
A
WARNING Running engine gives off carbon
monoxide, an odorless, colorless, poison gas.
Breathing carbon monoxide could result
in death serious injury, headache, fatigue,
dizziness, vomiting, confusion, seizures,
nausea or fainting.
Operate this product ONLY outdoors in an area that
will not accumulate deadly exhaust gas.
Keep exhaust gas away from any windows, doors,

and maintained indoors according to the
manufacturer’s instructions/recommendations.
Smoke alarms cannot detect carbon monoxide gas.
10
All fossil fuel burning equipment, such as standby
generating sets, contains carbon monoxide (CO) gas
in the engine exhaust. CO gas is odorless, colorless
and tasteless and is unlikely to be noticed until a
person is overcome. CO gas can kill you so it is
required that the following is included as part of the
installation:
Install generating set outdoors in an area that will
not accumulate deadly exhaust gas.
DO NOT install generating set where exhaust gas
could accumulate and enter inside or be drawn
into a potentially occupied building or structure.
It may be required to have a Carbon Monoxide
(CO) detector in operating condition in your home.
Carbon monoxide detector(s) (A) MUST be
installed and maintained indoors according to the
manufacturer’s instructions / recommendations.
A CO monitor is an electric device that detects
hazardous levels of CO. When there is a buildup
of CO, the monitor will alert the occupants by
flashing visual indicator light and alarm. Smoke
alarms cannot detect CO gas.
Your neighbor(s) home may be exposed to the
engine exhaust from your standby generating
set and must be considered when installing your
standby generating set.
Ensure exhaust gas is kept away from:
B - windows
C - doors
D - ventilation intakes
E - soffit vents
F - garage doors
G - crawl spaces or other openings that can allow
exhaust gas to enter inside or be drawn into a
potentially occupied building or structure.

The Gaseous Fuel System
The information below is provided to assist
gaseous fuel system technicians in planning
installations. In no way should this information
be interpreted to override applicable fuel gas
codes. Consult with your local fuel supplier or Fire
Marshall if questions or problems arise.
TO THE INSTALLER: Consult with the generating
set owner(s) and convey any technical
considerations that might affect their installation
plans before applying these general guidelines.
The following general rules apply to gaseous fuel
system piping:
NOTICE The supplied flexible
steel fuel line
is not to be
installed underground or in contact with the ground.
The entire
flexible
steel fuel line must be visible for
periodic inspection and must not be concealed
within nor contact nor run through any wall, floor,
or partition.
The piping should be of a material that conforms
to federal and local codes, 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.
NOTICE The illustration is representative of a typical
installation. Your installation may differ.
Install the
flexible
steel fuel line (B) (supplied)
between the generating set fuel inlet port (A)
and rigid piping to prevent thermal expansion,
contraction, or any standby movement from
causing excessive stress on the piping material.
A union (C) or flanged connection shall be
provided downstream to permit removal of
standby.
A manometer port should be provided (D). A
digital manometer, P/N 19495, is available at
your Briggs & Stratton service center. When the
initial test runs are completed, the manometer
is removed and the port is plugged. The
manometer port permits temporary installation of
a manometer to ensure that the engine receives
the correct fuel pressure to operate efficiently
throughout its operating range.
Where the formation of hydrates or ice is known
to occur, piping should be protected against
freezing. The termination of hard piping should
include a sediment trap (F) where condensate is
not likely to freeze.
A minimum of one accessible, approved manual
shutoff valve (E) shall be installed in the fuel
supply line within 180 cm of the generating set.
A manual fuel shut-off valve should be installed
in the interior of the building.
Where local conditions include earthquake,
tornado, unstable ground, or flood hazards,
special consideration shall be given to increase
strength and flexibility of piping supports and
connections.
Piping must be of the correct size to maintain
the required supply pressures and volume flow
under varying generating set load conditions
with all gas appliances connected to the fuel
system turned on and operating.
Apply thread sealant approved for use with NG/
LPG on all male threads only per sealant
manufacturer’s instructions and applicable
codes and standards.
NOTICE Keep thread sealant out of the gas
piping to prevent component part damage.
Installed piping must be properly purged and
leak tested, in accordance with applicable codes
and standards.
WARNING
Propane and Natural Gas are
extremely flammable and explosive,
which could cause burns, fire or
explosion resulting in death or serious
injury.
LP gas is heavier than air and will settle in low
areas.

Fuel Factors
An important consideration affecting the entire
installation is the type of fuel used by your generator.
The system was factory tested and adjusted
using natural gas, but can be converted to use LP
vapor. For proper engine function, factors that are
inherent to each of these fuels, your location and the
duration of possible utility interruptions are important
considerations in the following fuel guidelines:
Use clean, dry fuel, free of moisture or any
particulate material. Using fuels outside the
following recommended values may cause
performance problems.
In engines set up to run on propane (LP),
commercial grade HD5 propane with a minimum
fuel energy of 2500 BTUs/ft3 with maximum
propylene content of 5% and butane and heavier
gas content of 2.5% and minimum propane
content of 90% is required.
Natural gas rating will depend on specific fuel but
typical derates are between 10 to 20% off the LP gas
rating.
Natural gas or LP engines are certified to operate on
natural or liquid propane gas. The emissions control
system for this engine is EM (Engine Modifications).
Fuel Pressure
Both LP vapor and natural gas fuel supply pressure
at the generator’s fuel inlet port should be between
the following levels at full load with all gas appliances
turned on
and operating.
NG is 5-7” W.C.
LP is 11-14” W.C.
Ensure that all gas line shutoff valves are OPEN and
that adequate fuel pressure is available whenever
automatic operation is desired.
Power Loss
Air density is less at high altitudes, resulting in less
available engine power. Specifically, engine power
will decrease 3.5% for each 300 meters (1,000 feet)
above sea level and 1% for each 5.6°C (10° F) above
25°C (77°F). Make sure you and your installer consider
these factors when determining total generator load.
Fuel Pipe Sizing
There are numerous on-line or otherwise-published
references for fuel pip sizing. For example, NFPA
54-Natural Fuel Gas Code, 2006 (Item #: 320-6031-06)
is a common resource.
The installer should consider the specific gravity of gas
and compensate for a nominal amount of restriction
from bends, fittings, etc. If an unusual number of
fittings, bends, or other restrictions are used, refer to
federal and local codes for guidance.

Fuel Conversion
The engine of your generating set system is factory
calibrated to run on natural gas (NG). It may also be
operated on liquefied petroleum (LP) vapor.
To configure the 6 kVA fuel system for LP use:
1. Set generating set system switch to OFF.
2. Remove 15 Amp fuse from control panel.
3. Remove roof and side panels.
4. Change main jet in fuel mixer following
instructions provided in LP Conversion Kit.
5. Replace side panels and roof.
6. Reinstall 15 Amp fuse in control panel.
7. Set generating set system switch to AUTO.
The system is now ready to operate automatically using
LP vapor fuel.
To configure the 8 kVA fuel system for LP use:
1. Set generating set system switch to OFF.
2. Remove 15 Amp fuse from control panel.
3. Open oil fill access panel.
4. Connect the fuel select solenoid by joining the
two-pin electrical connector.
5. Reinstall 15 Amp fuse in control panel.
6. Set generating set system switch to AUTO.
7. Close access panels.
The system is now ready to operate automatically using
LP vapor fuel.
