ITEMS YOU MUST PURCHASE:
• Battery - Automotive type Group 26 negative
ground minimum 350 CCA at 0°F (7 kW) or a
minimum 525 CCA at 0°F (10 kW, 13 kW and
16 kW)
• 40 Amp (7 kW) or 70 Amp (10 kW, 13 kW and
16 kW) double pole circuit breaker (Must be
compatible with your main distribution panel.)
• Grounding rod with grounding strap
• Padlock (To lock external connection box)
• Crushed stone or pea gravel (approximately
10-12 cubic feet)
• Black poly-film or other vegetation blocking
fabric (5-1/2' x 5')
• Silicone caulk
• Pipe sealant (suitable for gaseous fuel
connections)
• Fasteners (to mount external connection box
and automatic transfer switch with built-in
emergency load center)
TOOLS REQUIRED:
Drill, drill bits, hole saw
(type and length will be
determined by the materials you will be drilling
and cutting), open-end wrenches or adjustable
wrenches, socket wrenches or nut drivers,
standard and Phillips screwdrivers, level, sledge
hammer, channel-lock pliers, spade shovel,

9a. Make the connection between the rigid fuel piping and the
generator using the supplied threaded flexible fuel line. The flex
hose should be straight.
Do not bend the hose in place of using
pipe elbows. Use a pipe sealant suitable for gaseous fuel
connections. Check connections for leaks by opening manual
fuel shut-off valve and swab or spray connections with soapy
water. If a leak exists the area will bubble with the presence of
the soapy water.
9b. If a leak is located, shut off fuel, and disconnect flexible piping.
Dry the threaded ends and reapply an adequate amount of pipe
sealant. Reconnect flexible fuel line, open fuel supply and
recheck for leaks. If leak still exists, repeat step 9b.
STEP 2
FUEL HOOK UP & CHECK FOR LEAKS
PLEASE NOTE: Natural gas pressure to the fuel
inlet on the generator must be 5 - 7” W.C. (0.18 to
0.25 psi). LP gas pressure to the fuel inlet on the
generator must be 10 - 12” W.C. (0.36 to 0.43 psi)
A primary regulator must be used if unit is
connected to an LP fuel tank (Primary regulator is
not supplied).

1. It will be necessary to pay a visit to your local municipal offices
to apply for a building permit. Building permits are necessary to
ensure proper installation, safety and adherence to all local
building code specifications. The location and phone number
can be found in the government section of your local phone book.
2. Plan the location of your generator. NOTE: Do not place the
generator directly under a window. Select an area outside of
your home nearest your incoming gas service.
3. Arrange for installation of rigid gas piping (per local code
specifications) to the location where you intend to position your
generator. Fuel piping should include a fuel shut-off valve. The
termination of the rigid piping should be aligned with the
generator fuel inlet located at the rear of the compartment.
4. Clear an area 5-1/2 feet by 5 feet minimum of grass and vegetation
to a depth of 5 inches. This includes the distance the generator
should be set away from any structure (3 feet) and 6 inches beyond
the width and length of the generator mounting pad (48” L x 24” W).
NOTE: Local codes may supercede these requirements.
5. Lay black poly-film to cover the area.
6. Fill the area to ground level with pea gravel or crushed stone.
7. Place the generator, which is attached to the mounting pad, on
the area you have just prepared.
8a. Drive an 8 ft. grounding rod into the ground to grade.
8b. Attach one end of the grounding strap (No. 12 AWG stranded
copper wire) to grounding rod and the other end to the grounding
lug (located at rear corner of unit). Make sure grounding rod and
strap are not exposed above ground level. (NEC code applies to
grounding method.)
NOTE: Generator mode switch should be placed in the “off”
position. Generator main line circuit breaker should be
switched to “off” or open position.

Converting to LP gas
From the factory, units are set-up for natural gas
operation. To convert for operation on LP gas refer to
