NOTE
: Air density is less at high altitudes,
resulting in less available engine power.
Specifically, engine power will decrease 3.5% for
each 1,000 feet (300 meters) above sea level
and 1% for each 10°F (5.6°C) above 77°F
(25°C). If the generator is not developing full
power, make sure these factors have been
considered when determining total generator
load output.
Reconfigure The Fuel System
The engine of your Home Standby Generator System is
factory calibrated to run on natural gas (NG). It may also
be operated on liquefied propane gas (LPG). There is no
additional hardware/equipment required to switch
between either fuel. However, LPG fuel inlet pressure
must be between 11 and 14 inches water column.
To reconfigure the fuel system for LPG use:
1. Open the control panel access door.
2. Set the SYSTEM switch to
OFF
.
3. Set the generator main circuit breaker
OFF
.
4. Remove the 15 Amp fuse.
5. Remove the cap from the fitting marked LPG
above the fuel regulator (
Fig. 5).
6. Remove the fuel supply hose from the NG fitting.
7. Pull hose through hole in sheet metal bulkhead
towards engine.
8. Remove and reverse fuel hose bushing and plug
in sheet metal bulkhead (Plug in top hole, bushing
in bottom hole).
9. Insert fuel hose in bottom hole towards regulator.
10. Install the hose on the LPG fitting.
11. Install the cap on the NG fitting (
Fig. 5).

12. Reinstall the 15 Amp fuse.
13. Set the generator main circuit breaker
ON
.
14. Set the SYSTEM switch to
ON
.
• Close the control panel access door.
The system is now ready to operate using LPG fuel.
The fuel mixer is set at the factory. No field adjustments
are required.
GENERATOR AC CONNECTION
SYSTEM
A single-phase, three-wire AC connection system is
used in the Home Generator System. The stator
assembly consists of a pair of stationary windings with
two leads brought out of each winding. The two windings
are connected together in series, resulting in a fixed
240VAC, 60Hz output. Stator output leads #11 and #44
are the two hot leads. The junction of leads #22 and #33
form the neutral lead (Fig. 6)
.
