gas line shutoff valves are OPENand that
fuel pressure is available whenever automatic

Power Loss
Air density is less at high altitudes, resulting in less available
engine power. Specifically, engine power will decrease3.5%
for each 1,000feet (300 meters) abovesealevel and 1% for
each 10° F(5.6°C) above 77% (25°C). Makesure you and
your installer consider these factors when determining total
generator load.
Fuel Pipe Sizing
Thereare numerous on-line or otherwise-puNished
referencesfor fuel pip sizing. For example,NFPA54-Natural
FuelGas 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, referto federal and local codes
for guidance.

Fuel Conversion
The engine of your generator system is factory calibrated
to run on natural gas (NG)or on liquefied petroleum (LP)
vapor, To convert to either fuel, follow these steps:
NOTICE Units are set to NG at the factory'.
1, insert key into lock of front panel.Gently push down
on roof above the lock to aid in turning the key,Turn
key one quarterturn clockwise,
2, Lift roof to the open position.
3, Pressthe control board OFFbutton,
4, Remove15 Amp fuse from control panel,
5, Removethe rear panel,
6, Locatethe fuel selectorswitch (A), locatedon top of
the fuel regulator (B). Using a 5 mm Allen wrench, turn
the selector switch to either LPor NG,
7, Install tamper proof plug supplied with unit.
Hug fits over fuel selector switch with convex

Generator AC Connection System
A single-phase, three-wire ACconnection system is usedin
the home generator. The stator assembly consists of a pair
of stationary windings with two leads brought out of each
winding. The junction of leads22 and 33 forms the neutral
lead,as shown schematically and as a wiring diagram. A
complete schematic and wiring diagram can be found laterin
this manual.
NOTICENeutral is not bonded to ground at generator.
NOTICE Generator must be usedwith only an ULapproved
transfer switch that is compatible with the generator.

Grounding the Generater
The homegenerator must be installed as part of a system
that includes a listed transfer switch, with neutral to ground
bonding at the transfer switch in accordancewith installation
instructions. Unless mandatedby local code, additional
grounding to earth at the generator is not required. Any
grounding at generator must use metal piercing lock
washers (or equal), UL listed terminals installed per terminal
supplier's instructions, and comply with nationalelectrical
codes and local requirements.
Utility Circuit Connection
"240V Utility" leads must be routed in conduit. The "240V
Utility" leadsdeliver powerto the generator's circuit board,
optional batterywarmer and optional oil warmer. This power
also chargesthe batter},.When power on these leads is lost,
the generatorwill start.
Using installerosuppliedminimum 30or, 6 AWGcopper
wire, or 300V, 4 AWG aluminum wire*, connect eachcontrol
circuit terminal in the generator (Utility A and Utility B)to
the fuse block in the automatic transfer switch.
*UseNational Electric Code for correction factors and wire
size calculations.
Generater Power Connection
Using installer supplied minimum 300V, 6 AW6 wire,
connect generator power output Line 1, Line 2, neutral and
ground to the corresponding Line 1, Line2, neutral and
ground in the transfer switch.
Transfer Switch Communication
Using installer supplied #18 AW6 twisted pair conductors,
no greater than 200 ft in length, connect Tx Rxand Tx Rx
GNDfrom the generatorterminal block to T!R and 6ND on
the transfer switch control board. When making connections,
obeywire type and torque specifications printed on the
circuit breakerand neutral/ground connectors.
