Onan BGE User Manual

Keep fuel lines awayfrom hot engine or exhaust areas.
This reduces chance of vaporlock. Install lines so that
they are accessible and protected from damage. Use
metal straps without sharp edges
to secure them.

breaking.
PROPANE (LPG) FUEL SYSTEM
(60 Hz Only)
+- Fuel System Provisions
' .- . Onan liquid LPG generator sets contain afiltercartridge
and magnet
in the fuel solenoid valve to protect the
solenoid valve and regulator valves from dirt and con-
taminants. The solenoid valve and
filter is shown in
Figure 11. Figure 12 shows the flow diagram for the
liquid LPG fuel system components used on thegenera-
tor

Generator set operation using liquid LPG is very sensi-
tive to altitude, temperature, and
BTU content of the gas.
Variation
in any one of these factors directly affects the
performance of the generator
set. Because of this, minor
adjustments
might be required after the installation,
refer to Generator Set Service
Manual if adjustmentsare
required.

Recommended Fuel
Use clean, fresh commercial propane or HD-5 grade
liquid propane gas in a mixture of at least 90 percent
propane. Propane
fuels otherthan HD-5 gradecan con-
tain more than
2.5 percent butane and can result in poor
fuel vaporization
and poor engine starting in low
ambient temperatures (below 32°F or
OOC).
Fuel Consumption
It should be noted that under varying electrical loads,
fuel consumption of engines for recreational vehicle
generator set varies accordingly. Average fuel con-
sumption
at various loads is shown in the table below.
LPG FUEL CONSUMPTION
Propane Fuel Lines and Supply Tank .
The installer must review all codes that apply to the
particular installation. Paragraph
3-5.1 (Gas Piping Sys-
tems) of NFPA Pamphlet 501C deals specifically with
propane fuel linesbutdoesnotnecessady coverall applicable
codes and regulations. You
can obtain this pamphlet
from the address listed in the beginning of this manual.
When installing the fuel lines, keep the following in
mind:
1. Install all propane fuel lines so they are accessible,
yet protected from damage.

Do NOT run fuel lines in conjunction with electrical

Most propane (LPG) liquid withdrawal generator set
installations are designed to share the vehicle propane
fuel supplytank(s). The vehicle propane fuel supply tank
MUST have a dip tube to ensure liquid withdrawal.
An excess flow valve MUST be mounted internal to the
propane
fuel supplytank(s) per NFPA 501 C, Paragraph
3-4.4. This excess flow valve and propane fuel lines
MUST be sized
so the excess flow valve will close with a
completely
severed (broken) propane fuel line. For
operation at the lowest ambient temperature, a valve
rated at
2.6 gallons per hour (9.9 Vhr) flow rate and 6.5
pounds per square inch (45 kPa) differential pressure is
recommended. Consult the Natural LP Gas Association
for
the limitations of excess flow valves.
