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.Reverse procedure steps
10.To adjust the system to run on LP fuel, simply turn the adjuster screw that is accessed from inside the front of the unit, 1/4 turn clockwise. This will now set the system for maximum power and best performance on LP fuel.
11.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 you experience prob- lems with the unit producing maximum power, follow the procedure in Section 2.6 (Adjusting the Regulator).

1.9LOCATION
◆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 5 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
The transfer switch shipped with this generator is enclosed in a NEMA 1 enclosure. This type of enclo- sure is intended for indoor use only. Follow these rules:
•Install the transfer switch indoors on a firm, stur- dy supporting 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 corrosive vapors.
1.10 BATTERY INSTALLATION
Fill the battery with the proper electrolyte fluid if nec- essary and have the battery fully charged before installing it.
Before installing and connecting the battery, complete the following steps:
1.Set the generator's Auto/Off/Manual switch to OFF.
2.Turn off utility power supply to the transfer switch.
3.Remove the 5A and 15A fuses from the generator control panel.
If the Auto/Off/Manual switch is not set to its OFF position, the generator can crank and start as soon as the battery cables are connected. If the utility power supply is not turned off, sparking can occur at the battery posts and cause an explosion.
