5. Remove the small brass hose fitting from the idle
circuit port of the regulator housing.
6. Remove the small jet (0D5698A) located in the
side of the regulator housing and install it into the
small threaded hole in the idle circuit port on the
regulator.
7. Refit the brass hose fitting to the idle circuit port
of the regulator. Use pipe thread sealant to reseal
the threads on the hose fitting.
8. Identify both adjustment screws.
NOTE:
One adjustment screw can be accessed from the
front of the unit and the second can be accessed
from the back of the unit.
9. To adjust the system to run on LP fuel, turn the
adjuster screw that is accessed from inside the
front of the unit 1/4 turn clockwise. This will set
the system for max power and best performance
on LP fuel.
10. The fuel system will now allow the engine to run
on LP fuel. It may be necessary to make minor
adjustments to the preset screw settings to
achieve maximum power. If there are problems
with the unit producing maximum power, follow
the procedure in Section 2.6 “Adjusting the
Regulator”.
11. Reverse procedure steps 1-4 to reinstall the
demand regulator.

1.9 LOCATION
1.9.1 GENERATOR
Install the generator set, in its protective enclosure,
outdoors, where adequate cooling and ventilating air
is always available. Consider these factors:
• Install the unit where air inlet and outlet openings
will not become obstructed by leaves, grass, snow,
etc. If prevailing winds will cause blowing or drift-
ing, you may need to consider using a windbreak
to protect the unit.
• Install the generator on high ground where water
levels will not rise and endanger it.
• Allow sufficient room on all sides of the generator
for maintenance and servicing. A good rule is to
allow 3 feet of space on all sides.
• Where strong prevailing winds blow from one
direction, face the generator air inlet openings to
the prevailing winds.
• Install the generator as close as possible to the fuel
supply, to reduce the length of piping.
• Install the generator as close as possible to the
transfer switch. HOWEVER, REMEMBER THAT
LAWS OR CODES MAY REGULATE THE DIS-
TANCE.
1.9.2 TRANSFER SWITCH
1.9.2.1 7 kW, 12 kW and 15 kW Units
Transfer switches for use with these generators are
sold separately and can be purchased from Generac
Authorized Dealers.
• Install the transfer switch on a firm, sturdy sup-
porting structure.
• To prevent switch distortion, level the switch if nec-
essary. This can be done by placing washers
between the switch enclosure and mounting sur-
face.
• Never install the switch where water or any corro-
sive substance might drip onto the enclosure.
• Protect the switch at all times against excessive
moisture, dust, dirt, lint, construction grit and cor-
rosive vapors.
• Failure to utilize a Generac/Guardian transfer
switch with this generator will void the warranty.
Transfer switches available for these generators are:
• Model 004678-0 — 100 Amp, 2 Pole, 250 Volt
NEMA 1 (indoor rated) or
• Model 004635-0 — 200 Amp, 2 Pole, 250 Volt
NEMA 3R (outdoor rated)
