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.

◆1.9.1 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.

•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.
