1. 

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. Determine where the
generator will be placed outside of the home.
Arrange for fuel  piping with shut-off valve to be run
to this location.  Keep in mind that GENERAC

®

recommends placement no closer than 3 feet to any
structure.

Local codes may dictate placement

farther from a structure.

The 3/4” fuel inlet is located

6 inches in from the rear of the unit on the right side
if facing the unit from the front.  The fuel inlet is 10.2
inches above ground. 

2.

Clear an area 

5-1/2

feet by 

5

feet of grass and

vegetation to a depth of 

5

inches. This includes the

distance the generator should be set away from a
structure (

3 feet

) and 

6

inches beyond the width and

length of the generator mounting pad 

(48" L x 24" W)

3.

Lay black poly-film to cover the area. 

4. 

Fill the area to ground level with pea gravel or
crushed stone.

5. 

Drive an 8-foot grounding rod into the ground to
grade. Make sure grounding rod and strap are not
exposed above ground level. (NEC code applies to
grounding method.)

6.

Determine where the flexible conduit will pass

through the house from inside to outside.  When you
are certain you have clearance on each side of the
wall,  drill a small pilot hole through the wall to mark

the location.  Drill a 1-3/4” diameter hole through the
sheathing and siding with hole saw.

7. 

While adhering to all local electrical codes, route the
30 foot conduit along ceiling/floor joists and wall
studs to the location where the conduit will pass
through the wall to the exterior of the house.
